i tried reproducing this on latest master (ubuntu 26.04 natively, plus an
ubuntu:20.04 container with gcc 10.5.0-1ubuntu1~20.04), with both make and
cmake, and it builds fine.
nuttx itself doesn't pass -lgcc_s. the gcc driver adds it to every dynamic
link, so a plain `gcc hello.c` would likely fail the same way on the affected
machine. the link-time `libgcc_s.so` comes from `libgcc-10-dev`, not
`libgcc-s1` (which only has the runtime `.so.1`), so that may be why installing
libgcc-s1 didn't help.
@PlutusCN @wangtao13 could you share the output of:
echo 'int main(){return 0;}' > t.c && gcc t.c -o t
gcc -print-file-name=libgcc_s.so
dpkg -l | grep libgcc
ls -l /usr/lib/gcc/x86_64-linux-gnu/*/libgcc_s*
and check whether `sudo apt install --reinstall libgcc-10-dev` (or the
version matching your gcc) fixes it?
