I’m porting the open source JAUS library from Linux to QNX.
After adjusting the Makefiles to use qcc (with the 3.3.5 compiler), switching from shared libraries to static ones and doing a few other minor changes to the Makefiles and code I have the project compiling and linking.
However when I link one of the test executables I get the following warning:
/usr/qnx630/host/qnx6/x86/usr/bin/i386-pc-nto-qnx6.3.0-ld: …/libopenJaus/lib/libopenJaus.a(FileLoader.o)(.debug_info+0x145e5): unresolvable relocation against symbol _ZZNSt13basic_filebufIcSt11char_traitsIcEE5_InitEP6_FiletNS2_7_InitflEE7_Stinit' /usr/qnx630/host/qnx6/x86/usr/bin/i386-pc-nto-qnx6.3.0-ld: ../libopenJaus/lib/libopenJaus.a(FileLoader.o)(.debug_info+0x1f24b): unresolvable relocation against symbol _ZGVNSt7codecvtIcc9_MbstatetE2idE’

I’ve never seen this before. It doesn’t appear to be an actual error because the executable is still created and seems to run fine. I suspect it’s because the code is a mix of C libraries with C++ high level wrappers/applications. But I don’t like seeing warnings during compilation and would like to clear this up. Does anyone know what this means?
TIA,
