gcc (GCC) 4.1.2 (Ubuntu 4.1.2-0ubuntu4)
I had two c++ files with private classes and other public functions. I linked
them with a third unit of main code (using gcc command line). Now the linker
linked the second compilation unit to the private class in the first
compilation unit not to its private class. The conflict was not detected by GCC
but was detected by MSVC. It result in the program getting SEGV in weird and
incomprehensible ways. The fix was to wrap the private classes in anonymous
namespaces.
Please add detection for this sort of conflicting symbols.
To build compilation unit
g++ -g -O0 -I../../lib_content_adaptor/include CContentPluginExample.cpp -c
-o CContentPluginExample.o
To build executable
g++ -g -O0 -o drivable_plugin drivable_plugin.o CContentPluginExample.o
-L/usr/lib/debug/lib -L../../build/x86/libs -l_content_manager
-l_content_adaptor -l_os -lpthread
