Hello,
It seems like the recent changes to make --no-allow-shlib-undefined
broke pructl.
lib/libc/stdlib/atexit.c uses a weak _Block_copy symbol, but
pructl does not use atexit_b, and yet gets the following error:
: && /usr/bin/cc -Werror -O2 -pipe -fstack-protector-strong -isystem /usr/local/include -fno-strict-aliasing -std=c99 -fstack-protector-strong CMakeFiles/pructl.dir/pructl.c.o -o pructl -Wl,-rpath,/usr/local/lib: /usr/local/lib/libpru.so && :
ld: error: /lib/libc.so.7: undefined reference to _Block_copy [--no-allow-shlib-undefined]
cc: error: linker command failed with exit code 1 (use -v to see invocation)
What is the correct fix? It seems like atexit.c or the linker should
be fixed, as pructl doesn't use atexit_b at all.
