I'm following the instructions here: https://github.com/symless/synergy-core/wiki/Compiling for compiling on OSX. I've "finished" everything. But I don't understand what to do to install synergy once the compiler has completed? I was expecting a nice output directory somewhere with a synergy.app or something in it. Am I missing something? I've used the GUI method using QT to compile the code as I didnt scroll down far enough initially to realise you can do it on the command line. But either way I've managed to get to the end of the instructions for compiling and I'm a little lost now.
Thanks
Once it's compiled, Synergy binaries are outputted to the build/bin directory inside whatever directory you cloned the Synergy source to (it was ~/git/synergy-core in my case).
You can run ~/git/synergy-core/build/bin/synergy (replacing with whatever your path is) to start the Synergy configuration UI which lets you configure your server or client as desired.

SO!
Let's say I have a number of settings (GCC compiler 9.3.0 built from source, as the distribution I have to use has a very old one, along with environment setup) for a new Kit in QtCreator.
I have managed to setup an environment for compilation and execution of compiled binaries, and made a script to make it work (like qmake -nocache -recursive/make/sudo make install, direct execution of g++, and other stuff).
One thing that script can't do at the moment, is that it cannot create a kit for QtCreator with new compilers and environment being set as required, so after running a script, its user has to go through setting it up himself through GUI, which is bad, because this can cause misconfiguration.
This thing I'm trying to create is going to be used by around ~200 people in my company, so leaving readme.txt with instructions just doesn't go well enough for me - I don't want running around fixing missing "{" and "}" in Environment description in created Kits, and other stuff.
Are there ways to create Kits for QtCreator automatically from command line? Maybe, there's some files to edit?
I've looked into this one a few years back (I wanted to do something similar for registering Buildroot toolchains automatically in QtCreator), and I was unable to find an off the shelf solution. So i think there are 2 ways to implement this:
a) Implementing a command line utility the manipulate the ~/.config/QtProject/qtcreator/{toolchains,profiles}.xml files. Maybe by (re)using the existing C++ implementation within QtCreator, or just re-implement it ie. in Python. Back than I didn't start to work on this as there was no real business need.
b) Switching to qbs, as qbs has support for setting up toolchains from the command line ( see: https://doc.qt.io/qbs/cli-setup-toolchains.html)
If you decide to go with solution a), please let me know and maybe we can partner up to implement it.
Check out the command line sdktool bundled with QtCreator:
The SDK tool can be used to set up Qt versions, tool chains, devices
and kits in Qt Creator.
There still is a lot of knowledge about Qt Creator internals required
to use this tool!
I haven't tried it yet, but I did find the executable under Tools/QtCreator/libexec/qtcreator subdirectory of the Qt Creator installation directory. ./sdktool --help works for me under Linux.
I am using Code::Blocks with wxwidgets and I have include and lib folders under Document\wxwidgets. I am very new to c++ libraries. In Code::Blocks project initialization, I entered the location for wxwidgets. Then in setting/global enviornment variables I entered in base the Document\wxwidgets again. Still, I am not able to run the app. It shows the error in the include/wx/platform.h file where it says
C:\Users\Programming coder\Documents\wxwidgets\include\wx\platform.h|148|fatal error: wx/setup.h: No such file or directory|
I am not able to solve this and would appreciate some help. Also I checked and the wx folder does not seem to be there in the location. I don't know if that is normal.
Also, I downloaded the headers(include) from the wxwidgets github repo download page, wxWidgets-3.1.1-headers.7z. Any help appreciated.
Also, I am aware some questions exist already, but their problems are in different because most are using linux. Also I am using Code::Blocks IDE.
You need to build wxWidgets itself before building the applications using it. Its build process will create the setup.h file which is currently missing.
Note that, in principle, you could also use precompiled binaries, but in this case you must use exactly the same compiler as was used for compiling them, i.e. TDM gcc.
I'd like to use open source library on Windows. (ex:Aquila, following http://aquila-dsp.org/articles/iteration-over-wave-file-data-revisited/) But I can't understand anything about "Build System"... Everyone just say like, "Unzip the tar, do configure, make, make file" at Linux, but I want to use them for Windows. There are some several questions.
i) Why do I have to "Install" for just source code? Why can't I use these header files by copying them to the working directory and throw #include ".\aquila\global.h" ??
ii) What are Configuration and Make/Make Install? I can't understand them. I just know that configuration open source with Windows need "CMake", and it is configuration tool... But what it actually does??
iii) Though I've done : cmake, mingw32-make, mingw32-make install... My compiler said "undefined references to ...". What this means and what should I do with them?
You don't need to install for sources. You do need to install for the libraries that get built from that source code and that your code is going to use.
configure is the standard name for the script that does build configuration for the software about to be built. The usual way it is run (and how you will see it mentioned) is ./configure.
make is a build management tool (as the tag here on SO will tell you). One of the most common mechanisms for building code on linux (etc.) is to use the autotools suite which uses the aforementioned configure script to generate build configuration information for use by generated makefiles which make then uses to build the software. make is also the way to run the default build target defined in a makefile (which is often the all target and which usually builds the appropriate library/binary/etc.).
make install is a specific, secondary, invocation of the make tool on the install target which (generally) installs the (in this case previously) built code into an appropriate location (in the autotools/configure universe the default location is generally under /usr/local).
cmake is, again as the SO tag says, a build system that generates configuration files for other build tools (make, VS, etc.). This allows the developers to create the build configuration once and build on multiple platforms/etc. (at least in theory).
If running cmake worked correctly then it should have generated the correct information for whatever target system you told it to use (make or VS or whatever). Assuming that was make that should have allowed mingw32-make to build the software correctly (assuming additionally that mingw32-make is not a distinct cmake target than make). If that is not working correctly then something is still missing from your system (and cmake probably should have caught that).
But to give any more detail you will need to give more detail about what errors you are actually getting and from what command.
(Oh, and on Windows, and especially if you plan on building your software with VS (or some other non-mingw32-make tool) the chances of you needing to run mingw32-make install are incredibly small).
For Windows use cmake or latest ninja.
The process is not simple or straight, but achievable. You need to write CMake configuration.
Building process is not simple and straight, that's why there exists language like Java(that's another thing though)
Rely on CMake build the library, and you will get the Open-Source library for Windows.
You can distribute this as library for Windows systems, distribute and integrate with your own software, include the Open Source library, in either cases, you would have to build it for Windows.
Writing CMake helps, it would be helpful to build for other platforms as well.
Now Question comes: Is there any other way except CMake for Windows Build
Would you love the flavor of writing directly Assembly?
If obviously answer is no, you would have to write CMake and generate sln for MSVC and other compilers.
Just fix some of the errors comes, read the FAQ, Documentation before building an Open Source library. And fix the errors as they lurk through.
It is like handling burning iron, but it pays if you're working on something meaningful. Most of the server libraries are Open Source(e.g. age old Apache httpd). So, think before what you're doing.
There are also not many useful Open Source libraries which you could use in your project, but it's the way to Use the Open Source libraries.
Firstly, I come from Windows-VisualStudio-C++ background. Now I am developing in a Ubuntu environment.
With the help of a Makefile, I built a mymodule.so and copied it to the modules folder within apache. Now, it appears that the module is working fine. But I would like to debug into this module to understand it better.
So, first, is there any way I can get something similar to the Visual Studio debugger type of feel while debugging this module?
Now, i read that i can use gdb to debug into apache modules, can somebody tell me in detail how this is done or point me to some resource that does it.
Ideally, i would like to single step and stuff. I am trying Code::Blocks IDE which has some debugging support. Using the IDE and custom make file, I build the module. Copied it to module location, but how do i debug.
How do i hook to the apache process. Should I use Attach to Process. I tried that with the pid of httpd, but with no success.
Also, while building is there some flag that i should set so that the .so file is debuggable?
I am pretty basic with Linux because i come from windows programming background. Kindly suggest how I go about this.
Thanks in advance,
Arjun
I think you can attach to an apache process using gdb (at 1111, where 1111 is the PID of the process, or in Code::Blocks) and set breakpoints in your module functions, if the module was compiled with debug. You will need to be root or the same user as the apache process.
gcc -g flag is used to build binaries with the debug info.
I've been interested in "D" for a couple of years now and recently decided to start actually playing with it. I've been able to grasp the basics quite easily, I love the basic feature set of the language and the more I read about it, the more impressed I get.
Now, I'm very interested in writing a custom web application server as a hobby project and I want it to be a simple binary, using dynamically linked libraries for the actual web applications. I believe D to be the perfect language for this venture.
There is only one big problem... over the past couple of days, I have been completely unable to get any kind of IDE setup working. I can compile and run everything just fine on the command line, but everything I try in any of the IDE's available (Code::Blocks, eclipse+descent, Xcode with D plugin, and even the windows D-IDE running in VirtualBox on Windows XP Pro) the only thing that ever happens is:
object.d: Error: module object cannot read file 'object.d'
After two days of trying different things and following tutorials, this is really getting on my nerves. I want to learn to use D efficiently, but I need some comfy tool chain that includes code completion in the editor if I want to keep my sanity, which I obviously do.
[edit:added emphasis to the really important bit]
Is there anyone that can help me set up eclipse or (preferably) netbeans (but no plugin seems to be publicly available) to give me compile and run abilities in the IDE, along with code completion? on my Mac, running Mac OS X 10.6?
I want to use the phobos libraries (and therefor a 2.0 compiler) but I don't really care if its dmd or gdmd (gdcmac).
[addition]
I believe we can assume that my dmd compiler installation is in order because it works from the commandline. I just don't want to use it from the commandline because its tedious. The question is about and IDE, the compiler works, its just IDEs that won't
Well, the persistent bugger in me could not leave the problem alone and I finally got it to work.
The required components to get it all working on Mac OS X 10.6 are:
DMD compiler
Eclipse "Galileo" (version 3.4)
Descent
DSSS
a change to /usr/etc/rebuild/default
a new file i hacked together /usr/etc/rebuild/macosx.conf
global and per-project settings for Eclipse
After following these instructions you'll have Eclipse able to do code completion on your D projects and you'll be able to build/run from within the IDE as well.
The actual steps to get it operational are as follows.
install the digitalmars dmd 2.0 compiler
download the binary distribution from digitalmars.com (direct link to 2.041)
unzip the downloaded file into ~/somefolder (that created a ~/somefolder/dmd2 folder for me which I'll use for the duration of this example.)
in the terminal (/Applications/Utilities/Terminal.app) move the files to their destination
sudo mv ~/somefolder/dmd2/osx/bin/* /usr/bin/ enter your login password when asked
move the just copied dmd.conf to its location: sudo mv /usr/bin/dmd.conf /etc/dmd.conf
sudo mv ~/somefolder/dmd2/osx/lib/* /usr/lib/
sudo mv ~/somefolder/dmd2 /usr/
use your favorite text editor to edit /etc/dmd.conf to contain the following:
[Environment]
DFLAGS=-I/usr/dmd2/src/phobos -I/usr/dmd2/src/druntime/import -L-L/usr/lib
Download and install your favorite Mac OS X version of eclipse out of the umpteen hundreds available at http://www.eclipse.org/downloads/ (I picked a cocoa version for c/c++)
Install Descent (almost as per the normal instructions in the wiki)
run Eclipse (don't bother running as root)
goto Help -> Install New Software from the menu bar. (wtf does that do in the Help menu?!)
copy/paste http://downloads.dsource.org/projects/descent/update-site into the url field.
follow on screen instructions to finish installation.
install dsss from sourceforge (direct link to .dmg)
use the installer package on the disk image like any other.
create a file /usr/etc/rebuild/macosx.conf and paste the following snippet into it. (and save, duh)
profile=phobos

change the /usr/etc/rebuild/default file to read: profile=dmd-macosx
Set up Eclipse to have code completion
In the global eclipse preferences navigate tp D => Build Path => User Libraries
click New, type "std", press OK select the newly created entry, click Add Directory
navigate to /usr/dmd2/src/phobos/std and add it.
Set up Eclipse project.
You have to do this manually for every D project you'll make
Create a new project with the "D => D Project" wizard (thanks to Descent)
Go into project properties (right click project in the Project Explorer and choose Properties)
In the list to the left select D Build Path and in the panel that appears choose the Include Path tab.
Click the Add Library button and choose std in the second page of the wizard.
Configure the extarnal build tool
Go to External tools configurations... (from the dropdown in the little green play button with the toolbox in front of it in the build/run/debug toolbar thingy)
In the list to the left right click Program and choose New from the context menu.
give your config a decent name like "Build with dsss" and set the following options:
Location: /usr/bin/dsss
Working Directory: full path to directory with your dsss.conf file for the project
(if you don't have a dsss.conf file create one on the commandline: dsss genconfig)
Arguments: build (or rebuild, or clean, or...)
repeat steps 2 and 3 above for as many build/run options as you require.
Congratulations, everything should work now.
If for some reason this does not work for you, let me know and I'll be happy to figure out where it went wrong and help you to get it working. If there's a better or simpler way, I'd love to know about it as well.
object.d: Error: module object cannot read file 'object.d'
clearly indicates that it can't find the libraries properly. So, the first question is how your dmd.conf is set up. You need to make sure that it's pointing to the correct places for src/phobos, src/druntime/import, and osx/lib - wherever you put those. Personally, I put the dmd code in a subfolder of home and don't try and install it in /usr, but the instructions do tell you to install them there as the default, so it should work.
Assuming that your dmd.conf looks okay, the most likely situation is that it's actually using the wrong dmd.conf. Per the instructions on the digital mars site ( http://www.digitalmars.com/d/2.0/dmd-osx.html ):
dmd will look for the initialization file dmd.conf in the following sequence of directories:
1. current working directory
2. directory specified by the HOME environment
3. variable directory dmd resides in
4. /etc/
My guess is that you put dmd.conf in /etc and have been editing that one but left the original dmd.conf in
/where_dmd_is/dmd2/osx/bin/
Certainly, I've had that happen to me a time or two. In any case, the first thing that you need to make sure of is that the dmd.conf that you're editing is the one that dmd is using (so make sure that the places where dmd looks first don't have a dmd.conf), and the second thing that you need to make sure of is that the paths in your dmd.conf correctly point to where the dmd stuff is. If those two things are correct, then dmd should find the libraries correctly.
On a side note, I would point out, however, given your comment about wanting to use shared libraries is that shared libraries don't work correctly with D2 right now (I have no idea whether they work with D1 since I don't use D1 - I suspect that they don't though). There have been discussions about it on the D newsgroup ( http://www.digitalmars.com/NewsGroup.html ), so you can look there. It is something on the radar and is being looked into, but doesn't fully work yet. Also, you can look to the newsgroup for further help on D-related issues. It's probably the best place to ask right now.
If it's a question of an IDE, as far as eclipse goes, I believe that the plugin to look at is descent: http://www.dsource.org/projects/descent
Unfortunately, I haven't tried it myself yet, so I don't know how good it is. According to its wiki page, it's primarily intended for D1 but does support D2 to at least some extent.
If you wanna get started quickly (aka Double-click-install): D for Xcode
Requirements:
Xcode
That's it. Installs the latest dmd compiler, so it works in Terminal too etc.
As i keep seeing this question coming back in my search results every now and then, I figured I'd keep it relevant.
Nowadays; In the Mountain Lion era, a much easier solution exists in the Mono-D project
Just install MonoDevelop (or Xamarin Studio) and follow the five minute installation manual
(You can use Phobos on D 1.0. Anyway…)
Where did you install the Phobos and druntime headers?
<the .zip file>/src/druntime/
<the .zip file>/src/phobos/
Usually I copy them into /usr/include.
(Also, try to edit dmd.conf to use the absolute path:
[Environment]
DFLAGS=-I/usr/include/phobos -I/usr/include/druntime/import -L-L/usr/lib
)
