Compilation fails (cdefs.h, stdio.h)

[nitardus]

I cannot get gcc to work at all: Even if I try to compile a simple Hello World program, I get the following output:

In file included from /data/data/com.termux/files/usr/include/sys/cdefs.h:429,
from /data/data/com.termux/files/usr/include/stdio.h:41,
from hello.c:1:

This is the output of gcc -v:

Any suggestions what has gone wrong? Thanks!

Try ndk r16 from this website https://chromium.googlesource.com/android_ndk/+archive/refs/heads/r16

Would you elaborate on your answer? What are these files? How does the NDK relate to this problem?

Android dropped support for gcc from ndk r18 thats why i am using a older ndk.

The container compressed folders which contain header files for c and c++ and libraries .

Decompress the files files using zarchiver then on termux use CD to navigate to one of the folder with c headers then go to bits and move all the files from there to $PREFIX/includes/bits then exit the bits directory then remove bits and copy all the folders and header files inside the folder to $PREFIX/includes. Repeat the steps for the second folder with c++ headers . Goto the folder containing libraries and move libgnustl_shared to $PREFIX/lib .

Now you can compile c programs with gcc file.c and c++ programs with g++ file.cpp -lgnustl_shared .

See #141 for what needs to be edited to get rid of the undefined "INTRODUCED_IN" in the standard headers

This issue is due to failing of setup-patchforgcc script. If you run it with -v flag, you will find these errors
