I am trying to build python wheels for multiple platforms using cibuildwheel on Github Actions, and I have succeeded with the MacOS and Linux images only after installing/upgrading automake, bison, flex, and swig. After that, to compile the C++ library and build the wheel it is essentially just autoreconf/configure/make/make install/python setup.py bdist_wheel. On the Windows image, I have tried many different things, but I am just too unfamiliar with Windows to make any progress. Chocolatey has winflexbison3 and swig, but does not appear to have autotools available. The Windows image README mentions pacman as a package manager, but I haven't successfully called it because it's not on PATH.
Is it possible to use a POSIX shell script like bash (not cmd or PowerShell) to do the whole build inside of Github's Windows image? If so, how can I install automake/autoconf/bison/flex/swig and then autoreconf/configure/make/make install? Specifically, how do I write the script and how do I call it in the Github Actions yml file?

I am trying to compile dlib 19.4 using the vcpkg tool
since I am having trouble compiling CMAKE and working with Boost.Python
to fix compiler issues for dlib.
Though I am having problems even running the basic steps
to get the vcpkg package to work:
(I also downloaded Visual Studio 2017 for this tool)
Looking at executed command (git init), you initialized empty git repository for vcpkg - that is likely wrong. This bootstrap.ps1 script fails internally when trying to fetch existing revisions. vcpkg doesn't want to reside in just any git repository, it wants "its" git repository. vcpkg uses git as a distribution platform and later to perform updates.
So instead, you should clone vcpkg repository to some directory, e.g.:
C:\test>git clone https://github.com/Microsoft/vcpkg.git vcpkg_test
Cloning into 'vcpkg_test'...
...
Checking out files: 100% (876/876), done.
C:\test>cd vcpkg_test
C:\test\vcpkg_test>powershell -exec bypass scripts\bootstrap.ps1
https://github.com/Microsoft/vcpkg/
Additionally I see errors regarding VS2017 C++ support. VS2017 is an IDE with multiple optionally supported languages (i.e. you could have only C# support installed). Please make sure you have "Desktop development with C++" workload installed - as vcpkg is for C++. You can update the installation at any time by running installer again (Modify).

I have an application that I built using Qt Creator on Linux and want to deploy it now. However, I don't want to statically build it as I don't want it to be open-sourced. I tried the ldd ./YourExecutable command, however that only lists (and not add) the additional dependencies the application needs in order for it to run. My question is, how do I gather the necessary dependencies without having to individually look for these files? Is there a tool, such as windeployqt.exe on Windows, that I can use on Linux for the same purpose? Or is there a better approach than the one I'm thinking of?
Get Cygwin setup.exe: http://www.cygwin.com/
1.1. Run setup.exe and continue to package selection list.
1.2. Under Devel catagory select tools you need for compiling your source. For
example 'GNU make'.
1.3. Finish installing.
Get linux crosscompilers for cygwin:
"cygwin-gcc-linux.tar.bz2" (68.2 Mb).
md5sum: 340e91a346f5bb17e660db10e43005b8
These compilers are made with crosstool 0.28-rc37. This package contains:
gcc-3.3.4 and gcc-2.95.3 for i386 (glibc 2.1.3) and gcc-3.3.3 for amd64
(glibc 2.3.2).
Note! There is now newer version of GCC avaible with glibc 2.3.2:
"cygwin-gcc-3.3.6-glibc-2.3.2-linux.tar.bz2 (i386, x86_64)".
2.1. Copy 'cygwin-gcc-linux.tar.bz2' to 'c:\cygwin' or install directory which
you selected in setup.exe.
2.2. Open Cygwin shell and change directory to root with 'cd /'.
2.3. Uncompress to Cygwin root with command:
'tar -jxvf cygwin-gcc-linux.tar.bz2'.
Cross-compilers are installed under '/opt/crosstool'. You can use theim
directly or with commands: gcc-linux, g++-linux, gcc-linux-2.95,
g++-linux-2.95, gcc-linux-x86_64 and g++-linux-x86_64.

It sounds like you want to use the shared library deployment option:
http://doc.qt.io/qt-5/linux-deployment.html#creating-the-application-package
Then if you wanted to go further than that, you could look into making a .rpm or a .deb .
There are lots of examples of qt projects that are now available on GitHub and have packages made. Usually for prebuilt binaries you need to make one for x86 and a separate one for x64.
Hope that helps.
So for example I am creating some app that uses boost or openCV and on my developer machine all that is installed so app compiles without any problem. But I wonder how to make app tell OS to download libs I use on first run? Is it possible? (sorry - I am linux noob)
This is what package managers are for. What you do is you compile your project, and then you build a package (e.g. .deb or .rpm), using the appropriate tools. While doing so, you can specify where the various files in your package should go, but also which other packages your package relies on. These are known as "dependencies", and package managers like apt and rpm are pretty good at resolving them.
Here's the official debian guide to making packages to give you an idea:
http://www.debian.org/doc/maint-guide/
Alternatively, you can just distribute your program as-is and list the dependencies in the install instructions; users will then have to manually install them through their package manager before running your program.
I am trying to set up a development environment to play around with developing Qt apps for Symbian devices. I have succesfully set up the environment and am able to create simple apps such as HelloWorld and get them to run on my device. I would now like to try using the QtMobility package, but I am struggling to get it to work in QtCreator.
I got some sample code for using the camera (initially I only had QtMobility 1.0.2, but I have now downloaded the 1.1.0 technology preview version). I followed the instructions in the help file to install it, here is what I did:
Extracted the zip file to C:\QtMobility
Opened a Qt Command prompt and ran configure (in the QtMobility directory)
Ran mingw32-make
Ran mingw32-make install
Finally I updated my PATH variable to include C:\QtMobility\lib
I went back to QtCreator (restarted it) and looked at the cpp file that first calls the macro QTM_USE_NAMESPACE but it is still underlined in red, because it can't find the qmobilityglobal.h file.
Does anyone know if I have missed anything out during the installation that will tell the QtCreator where to find the QtMobility header files?
mingw32-make suggests you're building for win32-mingw target environment. To work with Symbian SDKs, you should be building for e.g. symbian-abld instead. The configure.bat script will auto-detect the target you are building for. Just make sure that QT_PATH environment variable points to a location where you have a Symbian build of the Qt toolchain.
(Also note that make install is unnecessary with symbian-abld - the build step already puts everything in place in Symbian SDK directories.)
I've been strugling for two weeks to create an environment for building a gstreamer plugin on windows (needed for a songbird addon).
I've installed MSYS, MinGW and Cygwin, then installed GStreamer OSSBuild, and I also downloaded the sources for Songbird, which come with their own precompiled version of gstreamer.
I was unable to run gst-inspect (or any other gstreamer applications) from the songbird sources and I figured I will settle for OSSBuild (as I was able to run gst-inspect from the compiled OSSBuild).
When following the instructions for building a GST plugin (found here) through, cygwin will not recognize the OSSBuild and the build fails when running autogen, with the following error:
checking for GST... no
configure: error:
You need to install or upgrade the GStreamer development
packages on your system. On debian-based systems these are
libgstreamer0.10-dev and libgstreamer-plugins-base0.10-dev.
on RPM-based systems gstreamer0.10-devel, libgstreamer0.10-devel
or similar. The minimum version required is 0.10.16.
configure failed
I could also not use MSYS or MinGW as they are unable to run autogen at all.
I understand that cygwin should have it's own gstreamer development packages but I couldn't find how to install them.
My question: How do I install the gstreamer packages in cygwin or how do I build using cygwin with the OSSBuild dependencies?
In short, how do I get an environment where I can build a gstreamer plugin under windows?
you can install precompiled gstreamer packages for cygwin at cygwinports. there you will find installation instructions and a list of available packages. you should not need to build them from source.
Configure's most likely going to look for libtool (.la) or pkg-config (.pc) files. Since OSSBuild is built using MSVC, you're not likely to get those files so configure can pick them up. However, you can manually create them and set them in a location to be picked up by the script. I do know that OSSBuild does have as its goal to eventually provide Visual Studio-compatible C/C++ project templates for GStreamer plugins as well as libtool and pkg-config files, but they're not available just yet.
If you checkout the OSSBuild source and can follow MSVC property files, you can see how the plugins are setup and configured.
