libktx for Windows 7?

[samsonsite1]

Hello,
How to compile libktx under Windows 7? I don't have Windows 10 or WSL (Windows Subsystem for Linux).
bash.exe executable is obviously missing on my system, and it doesn't seem available either.

Compiling requires C++11 (at least Visual Studio 2015 but VS 2017 or later is recommended as we have to disable a bunch of warnings in VS 2015) so the first thing to determine is if that version of VS or later can run on Windows 7. Only 64-bit builds are supported so you'll need a 64-bit Windows 7 to run the software. Git for Windows includes a bash executable that can be used. It is based on MinGW and is likely easier to install and more lightweight than Cygwin, the other obvious alternative for getting bash.

Have you tried using the released Windows package on Windows 7? I do not have a Windows 7 machine so I can't try it myself.

Git For Windows, that worked, thank you.

btw, compiling with VS 2015 fails for Release mode.

To build astcenc-avx2-static under Release mode, I had to disable C/C++ Optimization for it.

The VS 2015 Release builds are working in our CI. According to the CI purveyor, they have VS 2015 with Update 3. Are you running at least that version? A very similar problem appeared in VS 2019 in one of its updates. A later update fixed it.
