[Dev-C++] Trying to link libmysqld.lib (Update)

[Josep S. <sub...@ar...>]

I thought maybe the lib for embedded mysql that comes with mysql is intended
for VisualC++ and that could be the reason why it doesn't work with
Dev-C++...

I have generated a libmysqld.def file with impdef(
http://webclub.kcom.ne.jp/ma/colinp/gcc.html) and then the library
libmysqld.a with dlltool (<-- included with mingw) but to no avail: Dev-C++
keeps spitting the same error (see below) log out when trying to compile
this new lib!
Anyone has an idea???

Actually, the def file and import library is not needed at all for GCC,=20
as it can use the DLL directly when linking.

Can you see the missing symbols in the def file BTW?
(Attaching that too would be a good idea)

Yes, the missing symbols are all there. For example mysql_error (Although
the compile log refers to something like "mysql_error@4" instead of just
"mysql_error":

...
[Linker error] undefined reference to `mysql_error@4'
...

And here is the .def file (after I created one with impdef, I found there
already was one .def file in another directory!):

MinGW can link directly to most of the DLLs. If your lib is a DLL (and 
not a static lib), you can add it to your linker options like it was 
just another lib.

By linking directly to libmysqld.dll instead of .a or .lib, the same errors
occur!

Thanks,
Josep

Could you create an archive of the lib, dll, def, .a, headers, sources=20
(actually everything required to compile your app), and put it up=20
somewhere, so I can download and experiment?

If you cannot put it up anywhere, then send it to this address (as a=20
last resort):
