Cannot build on termux

[ytest6709]

When tried to building the clib, it get error while trying to make install

src/common/clib-package.c:1081:5: error: call to undeclared function 'pthread_cancel'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
 1081 |     pthread_cancel(fetch->thread);
      |     ^
src/common/clib-package.c:1081:5: note: did you mean 'pthread_once'?
/data/data/com.termux/files/usr/include/pthread.h:258:5: note: 'pthread_once' declared here
  258 | int pthread_once(pthread_once_t* _Nonnull __once, void (* _Nonnull __init_routine)(void));

And were tried to build with CFLAGS="-Wno-error=implicit-function-declaration"

It get failed with

ld.lld: error: undefined symbol: pthread_cancel
>>> referenced by clib-package.c                                >>>               /data/data/com.termux/files/usr/tmp/clib-package-b790c2.o:(fetch_package_file)
cc: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:53: clib] Error 1

How can I fix this?

Unfortunately, bionic (Android's libc) does not implement pthread_cancel. An easy fix is to disable threads completely by running make with NO_PTHREADS=1.
