IceWM building on Termux

[IntinteDAO]

Unfortunately I'm very weak in C++ code, so I'd love to know if you are able to help make suitable patches or improve the IceWM code to also include Termux.

What is Termux? Termux is a terminal emulator and tool for Android. So you could say it's kind of like Cygwin for Android. Termux has its own X Server, and while it is Linux itself (because Android is Linux), it is based on Android Libc instead of GNU Libc, and the default compiler is Clang.

So I generally build code using CMake. The configuration executes correctly, but I get an error when building:

Maybe you have some idea how to fix it?

Replace the #ifdef __linux__ at line 662 with:

#if defined(__linux__) && defined(_GNU_SOURCE)

If that doesn't work, give the output of gcc -dM -E - </dev/null.

[IntinteDAO]

Thank you for reply. This code doesn't work.

gcc: https://privatebin.arch-linux.cz/?cf6de9f4a0341fa6#FdewKVgBPvqVnQF2w9zbq9Pxwc7PTwoBog1h76oU8h2w

clang: https://bin.nixnet.services/?6250b0193a36a80b#EQFjiJRcu7Mmiqvk6nd3PcdbKpyF3LkdKCLvx6x414w3

[gijsbers]

Why doesn't it work?

Does this work?

#if defined(__linux__) && defined(_GNU_SOURCE) && !defined(__ANDROID__)

Why? Reason.

[IntinteDAO]

This one works. I'm working with new issues now

[IntinteDAO]

The project is builded, now I tested and give u feedback

[IntinteDAO]

I also needed to change something in icewm-menu-fdo, because desktop files in Termux is /data/data/com.termux/files/usr/share instead /usr/share.
