Linkage problems with a dll in Visual Studio #152

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
1. Create a dll with yaml-cpp 0.3.0 under Visual Studio 8 2005.

2. Try to link "run_tests"

This gives the linker errors

Error 1 error LNK2019: unresolved external symbol "void __cdecl 
YAML::operator>>(class YAML::Node const &,class YAML::Binary &)" 
(??5YAML@@YAXABVNode@0@AAVBinary@0@@Z) referenced in function "public: class 
YAML::Binary const __thiscall YAML::Node::to(void)const " 
(??$to@VBinary@YAML@@@Node@YAML@@QBE?BVBinary@1@XZ) parsertests.obj

Error 2 fatal error LNK1120: 1 unresolved externals 
....\yaml-cpp_dll\build\test\Debug\run-tests.exe 1

This looks like just not exporting the symbols, a la issue 88.

I fixed it. In include/yaml-cpp/binary.h:
