I need to set up sqllite for Perl on a Windows box. However - Perl is probably being run over the network from a central server, and I do not know what modules will be available on initial running of my script.
I can guarantee Perl 5.8+ (activestate) or Perl 5.10+ (strawberry).
Therefore, I need to package sqlite & the associated Perl module(s) in the project directory itself. Having Goggled around, I don't see any immediate zipfile to do this.
DBD::SQLite is included into Strawberry (any version) and ActivePerl (AFAIK starting from 5.8.8 build 820). For other modules you can use PAR::Packer to package into .exe.
The DBD::SQlite distribution should have everything you need for SQLite. It comes with the Perl interface and all the SQLite stuff you need. You'll also need the basic DBI package too.
However, I encourage you to set up whatever application you have to install as a Perl distribution with dependencies, etc. Then you just install your application as a Perl module with the normal Perl tools. You specify whatever you need in the tool configuration at installation time. That way you aren't creating some new system that you have to explain to other Perl programmers, create new tools for, or maintain in some odd way.
You can even set up your own internal mini-CPAN with just the modules you need so you can control it within your network. See, for instance, my DPAN stuff.

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'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.
Is there any way to create executable binaries from Ruby/Rake task?
I have simple FileUtil tool written in ruby and I'd like to package it somehow into script that can be run or OSX, Linux or Windows. Is there any way to do that?
Ruby is an interpreted language and not a compiled one like C or Java. Then answering your question is not so easy.
But there are some tools that permit you to protect your source code (encrypting) and creating some packages that are runnable cross platform (but in this case you should ever resolve any dependency).
This question covers pretty good how you can distribuite your code without (or encrypting) your source code: Can you Distribute a Ruby on Rails Application without Source?
Other useful tools that I have founded in these moments:
- Compiling a rake https://github.com/luislavena/rake-compiler
- Debian (.deb) packaging http://crohr.me/pkgr/
I am supposed to switch our development environment from ActiveState Perl 5.6.0 to Strawberry Perl 5.12 but I am stuck on one Module.
We have created our own Module which also includes a dll (for performance reasons). Now that module was compiled for Perl 5.6.0. The Problem is, that we do not have the sourcecode anymore, but we need to get that module somehow working with the new Perl Version.
Is there even any chance to do this, without having to recompile that module for perl 5.12?
When I try to load it, it says that it cant find the required dll, but the path is correct and the file is there, so it seems to be a loading problem with the versions.
TIA
Patrick
No. The Perl library is not guarantee to maintain binary compatibility between major versions, and something compiled for 5.6 is not binary compatible with the Perl 5.12 library. The only way to load that module is if Perl 5.6 is involved somehow.
I downloaded everything described as in pygtk for installation. Everything went fine until when I tried to type "import gtk", it threw an ImportError as follows:
from gtk import _gtk
ImportError: DLL load failed: ...(something unreadable)
Then I re-install the pygtk-2.22.0 again, the same problem existed. So what to do please? Thanks in advance!
The error you describe is usually caused by the python bindings (pygtk/pygobject/pycairo) being unable to load a dll it needs to function properly. Most of those errors are either caused by:
the GTK+ runtime not being on your PATH environment variable. This has long been
the advice on how to get pygtk working on Windows. Please don't change your user
or system PATH environment variable, it is no longer needed with the all-in-one
installer.
multiple GTK+ runtime versions are on your PATH environment variable and the first
(leftmost) one is not compatible with the pygtk/pygobject/pycairo versions you use.
This is why adding the GTK+ runtime to your PATH environment variable is a bad idea:
it is easy to mix up versions (sometimes GTK+ related installers add their bin
directory to PATH on installation which contains an older or incomplete runtime).
a rare case where some software package installed libintl.dll and iconv.dll into
%WINDIR%\system or %WINDIR%\sytem32
The most straightforward way to avoid the dll hell described above is to use the
PyGTK All-in-one installer (http://download.gnome.org/binaries/win32/pygtk/2.22/).
It contains both the Python bindings, the GTK+ runtime and even Glade and does
no longer require you to change the PATH environment variable.
Small warning: if you decide to use the all-in-one installer, you'll have to uninstall
the separate pygtk/pygobject/pycairo packages you've used before (or you'll be in
a world of trouble...)
read the source code, perhaps there is a need for a specific version of pygtk
edit the source code to work with your pygtk version
I had this issue as well. You didn't mention for sure in your answer, so I'll suggest the obvious (well...the obvious to people that have used it a while, perhaps). Did you use the following three lines of code to import? You have to use these, in order, to import PyGTK.
I'm assuming your version here is 2.24 like mine. If not, change it to the version you have.
import pygtk
pygtk.require('2.24')
import gtk
That should suffice in importing gtk.
Problem
As others have noted, don't put gtk in the path. I know, its tempting, and it works for XYZ, but it (to say the least) gets confusing. Dependency hell is bad enough on a platform like Linux which tries to make it easy for you.
For clarification, what the PyGTK All In One does for you is to install (what appears to be) a full gtk+ runtime directly in your python packages folder, so e.g. in C:\Python\Lib\site-packages\gtk-2.0\runtime
Solution
NOTE: %YOURPYTHONPATH% is an EXAMPLE variable which contains the path of your Python installation (e.g. C:\Python, or C:\Python27, or whatever it actually is). I suggest setting %PYTHON_DIR% or %PYTHON_PATH% if you want to use a variable to do this, as more programs are likely to use this.
To get your XYZ program requiring GTK to work, add %YOURPYTHONPATH%\Lib\site-packages\gtk-2.0\runtime\bin to the PATH when running your program; the correct versions of the DLLs it needs to link against are in that folder. All other GTK+ runtimes I had installed (GTK+/GTK2-Runetime) gave me errors.
Again; Do not attempt to set a user or system level variable (don't open up the dialog pictured below) as this will likely cause problems for you later unless you VERY sure you know what you are doing. If you are reading this, you most likely don't know as much as you think you do. Instead, alter the path in a cmd prompt, or use a batch/script file to set it up for you.
After you install the pygtk.org package, install each of these in the following order:
pycairo-1.8.6.win32-py2.6.exe
pygobject-2.20.0.win32-py2.6.exe
pygtk-2.16.0+glade.win32-py2.6.exe
gtk+-bundle_2.16.6-20100912_win32.zip
