[Mingw-users] dll.a linking headache

[Vetrov M. <mu...@ma...>]

Hi,

Got error "The procedure entry point mysql_init@4 could not be located 
in the dynamic link library libmySQL.dll" after starting test app.

History:

1. created .def and .a files from libmySQL.dll (compiled with VC++50, 
__cdecl, 8-byte struct member alignment,multithreaded):

  pexports libmySQL.dll -o > libmySQL.def
  dlltool  -def libmySQL.def -dllname libmySQL.dll --output-lib libmySQL.a

2. Got error about undef reference to the mysql_init@4 while compiling 
test app that called that function. I read mailing lists and then I 
tried different combinations of libmySQL.a location on the compile line 
without any success.

3. I read "Stdcall and DLL tools of MSVC and MinGW" article, but it says 
that function@n should go with __stdcall and not with __cdecl!!! 
However, I manually changed def file line from

mysql_init  @63

to

mysql_init@4  @63

and recreated libmySQL.a.

4. Test app compiled sucessfully, but I got error "The procedure entry 
..." (see the first line) when I ran it.

I'll be glad to get any ideas what I have done wrong.
