Hello All! I have followng problem some dll - which I try build under gcc 3.3.1 used STL Port dll - but this dll is builded under VC6 - so I have 1 lib (assumed as import lib) and 1 dll (this dll is stripped - so I can't used NM for make def. file) When I try build(linking process) together - I recieved undefined reference to `_STL::........' and this every time - neither I pass stl_port.lib in linking libraries or stl_port.dll I am using MinGw 3.3.1 (together with MinGw Developer studio) but same problem under CygWin So , question , is any problem when I try linking VC6 builded libraries /dll or I can pass some parameter in linking options ? Is any critical diffirencies between VC and GCC builded libraries ? Thank you
