Hi all. I have a locally-built relocatable GCC toolchain (GCC 4.8.0 / binutils 2.23.2). By this I mean that the compiler was built to install into a location that no longer exists and was built against a sysroot that no longer exists. All its builtin paths no longer exist on the system. The only way the compiler can find anything is if I add the --sysroot flag to all invocations... which I do. I'm building some executables and a shared library, then I'm linking the shared library with some unit test programs, all using this same compiler with the same value of --sysroot. I know the --sysroot is good. I want the executables to not depend on the version of GCC installed on the target system so I'm linking them with -static-libgcc -static-libstdc++ (it's all C++ code, both the executables and shared library). This works fine: they link, ldd shows no prerequisites, and they run fine on all the target platforms even the old ones. Note that these executables do NOT link the shared library. When I build the .so I do _not_ use the -static-* flags and when I use ldd on the .so I see it referencing the real system libstdc++. That's OK. If I link the unit test programs with the shared library normally by hand, everything links and works fine. However it turns out that in my build system it's tricky to get the real executables to use the -static-* flags but the test programs to NOT use the -static-* flags... and when I try to link the unit test programs with the -static-* flags AND with the shared library, I get a ton of failures (see below). It's odd to me that linking my exe with -static-* works, and linking with my shared object without -static-* works, but linking with my shared object AND with -static-* fails. Any thoughts? /.../cc/generic/bin/../lib/gcc/x86_64-generic-linux-gnu/4.8.0/../../../../x86_64-generic-linux-gnu/bin/ld: warning: libstdc++.so.6, needed by ../libSharedLib.so, not found (try using -rpath or -rpath-link) ../libSharedLib.so: undefined reference to `__cxa_allocate_exception@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__cxa_throw@CXXABI_1.3' ../libSharedLib.so: undefined reference to `operator delete(void*)@GLIBCXX_3.4' ../libSharedLib.so: undefined reference to `operator new(unsigned long)@GLIBCXX_3.4' ../libSharedLib.so: undefined reference to `vtable for __cxxabiv1::__class_type_info@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__cxa_end_catch@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__cxa_rethrow@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__cxa_call_unexpected@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__gxx_personality_v0@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__cxa_free_exception@CXXABI_1.3' ../libSharedLib.so: undefined reference to `operator delete[](void*)@GLIBCXX_3.4' ../libSharedLib.so: undefined reference to `typeinfo for std::exception@GLIBCXX_3.4' ../libSharedLib.so: undefined reference to `__dynamic_cast@CXXABI_1.3' ../libSharedLib.so: undefined reference to `vtable for __cxxabiv1::__si_class_type_info@CXXABI_1.3' ../libSharedLib.so: undefined reference to `__cxa_begin_catch@CXXABI_1.3' ../libSharedLib.so: undefined reference to `vtable for __cxxabiv1::__vmi_class_type_info@CXXABI_1.3' ../libSharedLib.so: undefined reference to `operator new[](unsigned long)@GLIBCXX_3.4' ../libSharedLib.so: undefined reference to `__cxa_pure_virtual@CXXABI_1.3' collect2: error: ld returned 1 exit status
