Title: msvc calling a dll built by c::b
Post by: coding_ant on December 12, 2010, 02:43:23 pm

1. I recently built a dll(C language), using default settings. (test_gcc.dll   test_gcc.dll.a)
2. I built another dll project(msvc 6.0 C++ language), using test_gcc.dll.a as an input.(test_msvc.dll)
3. I built an host execuatable project using msvc 6.0.(test.exe)

when i debug test_gcc.dll, an segment error will pop up. Can anybody give me some hints what i missed?

Yes, You wrote bad source code is the most likely cause.

thx, i reviewed my code and fixed a bug. Now i run into another, when i debug test_gcc.dll using c::b, i was presented with a pop-up dialog saying "signal SIGSEGV,Segmentation fault" when i call any exported function that is before i execuate any code in the test_gcc.dll. so any idea?

Search more about compiler/DLL binary incompatibility. Even different major versions of GCC produce incompatible binaries, so that's might be your case. Can't tell for sure, though.
