The upstream project doesn't have this problem because they don't use -Wl,--no-undefined.

I leave it unresolved because I can't find other ways to solve the problem. The environ symbol doesn't exist in any shared library, so it can't be resolved by adding -l arguments. I also tried to add crt1.o to the linking arguments, but it also doesn't work.

If I use /usr/lib/crt1.o:
ld: /usr/lib/crt1.o: relocation R_X86_64_32 against `_DYNAMIC' can not be used when making a shared object; recompile with -fPIC
/usr/lib/crt1.o: error adding symbols: Bad value
clang++: error: linker command failed with exit code 1 (use -v to see invocation)

If I use /usr/lib/gcrt1.o:
ld: /usr/lib/gcrt1.o: relocation R_X86_64_32 against `_DYNAMIC' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcrt1.o: error adding symbols: Bad value
clang++: error: linker command failed with exit code 1 (use -v to see invocation)

If I use /usr/lib/Scrt1.o:
/usr/lib/Scrt1.o: In function `_start':
/usr/src/lib/csu/amd64/crt1.c:(.text+0xa4): undefined reference to `__preinit_array_start'
ld: /usr/lib/Scrt1.o: relocation R_X86_64_PC32 against undefined hidden symbol `__preinit_array_start' can not be used when making a shared object
ld: final link failed: Bad value
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
