Description

Hello.

I have successfully built uchardet in my cross environment (build is amd64, host is arm). Now I'm trying to link to it.

cat test.c

int main() { return 0; }

arm-unknown-linux-gnueabi-gcc test.c -luchardet

/usr/libexec/gcc/arm-unknown-linux-gnueabi/ld: warning: libstdc++.so.6, needed by /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so, not found (try using -rpath or -rpath-link) /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to __gxx_personality_v0@CXXABI_1.3' /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to vtable for __cxxabiv1::__si_class_type_info@CXXABI_1.3' /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to __cxa_pure_virtual@CXXABI_1.3' /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to vtable for __cxxabiv1::__class_type_info@CXXABI_1.3' /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to operator new(unsigned int)@GLIBCXX_3.4' /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to __cxa_end_cleanup@CXXABI_1.3' /usr/arm-unknown-linux-gnueabi/usr/lib/libuchardet.so: undefined reference to `operator delete(void*)@GLIBCXX_3.4' collect2: error: ld returned 1 exit status

arm-unknown-linux-gnueabi-gcc test.c -luchardet -lstdc++

As you can see without adding -lstdc++ I cannot link to uchardet. This problem affects real applications (e.g. mpv), which rely on linker flags provided by uchardet.pc. But uchardet.pc provides only -luchardet, while -lstdc++ is listed under Libs.private. Is there a sane way to deal with this problem?

Thank you.

P.S. gcc test.c -luchardet on native system works just fine.
