pkg install libcrypt

Also there no dev packages. Termux no longer does splitting. So libcrypt-dev == libcrypt, same with other packages.

My question is : error: crypt.h: No such file or directory

suhan-paradkar commented 3 years ago

My question is : error: crypt.h: No such file or directory

Yea.. that can be solved by pkg install libcrypt

You may need to manually specify CPPFLAGS.. Pointing to $PREFIX/include

ghost commented 3 years ago

Yes, crypt.h is in $PREFIX/include.

You may also try termux-chroot, if your build tool tries to use locations like /usr/include which do not exist in Termux because it is not FHS-compliant.

Amazing, It's work! Thanks for your help!

Maybe disabling nls may help

ghost commented 3 years ago

@suhan-paradkar There issues with threading, not with NLS. Termux (Android) has limited support for pthreads. Many stuff is missing.

gcc isn't supported by Termux officially, this could also lead to problems. clang should be used instead. The right use of gcc is only for GNU extensions of C language, which are not parts of the standard C. Though nowadays only rare software relies on GNU extensions.

Does Termux's Python support packaging as a dynamic library? Then use my C code to call the Python generated .so file?

I have tested some Python packaging tools and found that the resulting.so file cannot be called. such as: Nuitka.

I asked the author of Nuitka, and this is his response: https://github.com/Nuitka/Nuitka/issues/1163.

What's different about the Python environment on the Termux?

ghost commented 3 years ago

Yes, our Python supports dynamic libraries.

Your issue is most likely https://github.com/android-ndk/ndk/issues/201. Binary doesn't expose symbols to loaded shared libraries. You should link your .so file with libpython to obtain symbols, otherwise it would not work. Android dynamic linker is not same as on normal Linux distributions - that's one of major differences you should know when using Termux.

If you need a traditional behavior, then use proot'ed or chroot'ed variants of Linux distributions inside Termux either through proot-distro or third-party installers.
