I'm working on a Rust project which uses the Graphviz library. Currently, I'm working on Ubuntu-based system where first I need to install Graphviz then I can use commands like:
dot -Tsvg test.gv -O
But what I need is a standalone executable that I can bundle up with my Rust project, so:
Whoever is using the project doesn't have to install Graphviz as a dependency first in their system.
I can use the bundled Graphviz executable to run the commands which are not dependent on the fact that the user has Graphviz installed or not.
It should be OS-independent so I can run the Graphviz dot command from the project on every platform.
So, is there any way to do this?
Thanks in advance!
Since I'm using Electron to integrate with Graphviz and use on any OS. I'm using a node module that works beautifully with Graphviz and also supports the HTML-like label (expat library) too.

I'm trying to install Yesod through cabal on my HP computer, but the building process fails when shakespeare library gets the turn. MSYS2+MinGW in the path, the rest actually works. What could be the issue? I have my suspicions that it might be due to the x64 processor I have, but not sure.
Tried installing globally with runhaskell, but same story.
C:\Users\Ivan Kretov>cabal install shakespeare
Warning: The install command is a part of the legacy v1 style of cabal
usage.
Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become
the default in the next version of cabal-install. Please file a bug if
you cannot replicate a working v1- use case with the new-style commands.

I'm looking for a way to build an Erlang project on Windows. I have Erlang installed and all project files, including makefile, cloned from GitHub. I would like to build the project as if I was using make command on Linux and run it. What tools can I use to do that?
I'd try cygwin. https://www.cygwin.com
http://erlang.org/doc/installation_guide/INSTALL-WIN32.html
You can either build erlang with cygwin or use gnu-make in combination with a native windows build of erlang
If you're asking "how do I run make in Windows?" then you can use Cygwin, the newly-available Bash shell, or the MinGW tools. These will all give you some level of ability to run make, though not every makefile will work.
If you're asking "how can I build an Erlang project using a makefile?" then you are looking for erlang.mk. Note that Rebar3 (which is configured with Erlang terms and looks nothing like a make system) was recently selected as the "official" build tool, but erlang.mk is quite popular and is well-maintained.
It says that Elixir has a tool called elixirc and Erlang has a tool called erlc to compile modules for use. It says immediately after this that you can then run code with the elixir command line tool.
Is there a way to compile a binary executable with Elixir or Erlang? (one which I can chmod +x binary_name and then run from the same directory with ./binary_name)
Escripts support that to some extent but you still need Erlang installed in your machine. See this answer for more information: Elixir or Hex portable package format?
Make sure you checkout Distillery. It does what you need, without having to deal with Rebar.
Add this to your mix.exs file's dependencies then run mix release.
defp deps do
[{:distillery, "~> 0.9"}]
end
Their documentation is great:
Home - Distillery Documentation
You can use tools like rebar to generate a release that also contains the erts, which makes it possible to run said release on a machine where erlang is not installed. But the erts included corresponds to the operating system on which the release was built, i.e. windows binaries if built on windows.
You can use Elixir's built-in releases as of Elixir 1.9. It is a lightweight alternative to Distillery.
Caveats:
It will not create anything remotely like Go does with a single binary executable that you can run almost anywhere. Also your target will have to match the CPU architecture and OS.
To build a release run:
mix release
Read more here:
https://hexdocs.pm/mix/Mix.Tasks.Release.html
There are a few tools now that allow you to create a self contained executable binary that doesn't require any dependencies on the target machine. They support multiple platforms.

I'm working on windows 7 64bit system using clozure cl (version 1.8-r15286m) with quicklisp installed.
I need some freetype2 bindings for common lisp. (map characters to glyphs + kerning info)
I've tried to install "cl-freetype2" using
(ql:quickload "cl-freetype")
from 32bit clozure cl, and I've run into several problems.
"grovel.lisp" (located in quicklisp/software/cffi_0.11.1/grovel/grovel.lisp) assumes that I have gcc installed at "c:/msys/1.0/bin/gcc.exe" (I have mingw-gcc in path, but not there). Fixed by replacing "c:/msys/1.0/bin/gcc.exe" with "gcc" in "grovel.lisp".
When trying to compile cffi bindings for freetype2, same file does not include drive letters when passing include directories to compiler (i.e. instead of -i"d:/somedir" it passes -i"/somedir" to gcc`).
"grovel.lisp" tries to include unix include directories.
I cannot fix #2 myself.
I found this discussions, tried both listed patches, and neither of them worked. (first one breaks cffi, because ccl can't find neither "namestring-prefix" function nor "pathname-prefix" function), second one does not fix the problem.
What can I do in this situation?
I'd prefer to avoid fixing "groveller" myself, I simply need some bindings for freetype2.
Basically, I need to be able to
Load truetype font.
Map unicode char to glyph.
Get kerning information for pair of glyphs.
Load glyph bitmap.
Any ideas?
Figured it out.
Installing cl-freetype2 via quicklisp requires fully functional installation of MinGW.
Ensure that mingw-gmp is installed. (mingw-get install gmp)
Ensure that mingw/bin directory is within system path (right click on "My Computer"->Properties->Advanced->Environment Variables). Is Set. Should be something like "D:/development/MinGW/bin " (assuming MinGW is installed in "d:/development").
Locate "grovel.lisp" within your ccl installation, and replace ""c:/msys/1.0/bin/gcc.exe" with "gcc". You don't have to do that if gcc is installed at this location.
Launch mingw shell.
download unpack and install latest Freetype2 tarball using ".configure && make && make install", similarly to unix enviornment.
Locate freetype-6.dll copy it into freetype.dll and move freetype.dll into location within system path.
(Assuming that MinGW is installed in "d:/development/MinGW"), create CPATH user environment variable with following context: D:\development\MinGW\msys\1.0\local\include\freetype2;D:\development\MinGW\msys\1.0\local\include. That is - if you didn't specify "/usr" prefix during freetype2 compilation.
From within mingw shell, launch wx86cl and try (ql:quickload "cl-freetype2"). It should work properly.
If it still doesn't work, in all your root drives create directory junctions to directory in which mingw is installed. (i.e. "c:/development" linking to "d:/development", etc).
I must admit that this was much hassle, so I still think that it'll be a better idea to make a small dll that provides minimal set of functions I need while using freetype internally, then load this dll using cffi. This should be much easier.
Is it possible to create Windows executable files for Python and C/C++ code within the Eclipse workbench? If yes, then how can this be done?
This is how I create .exe files from eclipse, in windows. Is not within the eclipse workbench but it might help you. To avoid problems, I would recommend to download everything for 32 bit even if you use 64 bit computer.
Install python 2.6
Install Eclipse
Install py2exe
In eclipse go to Help > Install new software and install pydev plugin from http://pydev.org/updates/
In windows preferences point the python interpreter to the location of your python.exe in your computer (C:/Python26)
you might need to add py2exe to the libraries
create a python module called setup.py with a code similar to this one:
from distutils.core import setup
import py2exe
setup(windows=['H:/yourworkspace/YourPythonProject/src/yourprogram.py'])
open windows console and type
python H:/yourworkspace/YourPythonProject/src/setup.py py2exe
this will create a .exe located in C:/Python26/dist folder. It should work if you double click it but you cannot take it to a computer without python or any of the libraries that you´ve used. To do that, you can use Inno Setup.
It's very easy to use, basically it will ask for the location of the .exe, the dlls and folders that you want to add (I don't know about this so I add most of the things inside my C:/Python26/dist and it works). Inno setup will create an script and generate a .exe that you can install in any computer. You might need to edit the [Icons] part of the script, I had problems with that before to add an icon to the application.
That should hopefully work,
good luck.
Not sure I understand what you're asking as you're mixing Python/C++ in your question...
If you want to embed Python in some library, Google for 'embed python in c++'
If you just want to package Python to run Python code with extension modules, search for py2exe or cx-Freeze (personally, I like cx-Freeze better).
I don't think any of this is PyDev/Eclipse dependent (this should be IDE agnostic).
In addition to Fabio's answer:
In terms of C/C++, if you compile it on windows, eclipse does create yourprog.exe file automaticaly in order to be executed (in case if you have your main function written in C/C++). Look for your executable in bin folder of your project.
In terms of compiler: I use Cygwin. It simulates Linux environment. It contains (not by default though) g++ compiler, which, because of cygwin, compiles it in binary that can be launched in Windows (i.e. .exe file). I am not sure exactly about whether Linux binary is then converted to Windows binary or it is directly compiled for windows, but I know that this .exe file alone works if you run it.
Let me know if you need help installing Cygwin.
