Hello everyone.
I've been trying to use MySQL in an application on Windows, but I 
always get
 Symbol Undefined _mysql_init


problem might be. I've tried several libs, and tried to compile 
it myself (always converted using coffimplib), but it fails, no 
matter what. I've also tried to make a def file out of the lib, 
and the functions are definitly listed as exports there.
Any idea what I might doing wrong?

Are you also including the library on the command line with -L-l? For 
example, for ncurses:

   dmd ... -L-lncurses ...

And if needed, also -L-L to specify the location of library files for 
the linker.

 Yes, I am including it. Tried pragma and command line. And I don't get a
 message that the lib couldn't be found.
 What exactly is -L-l supposed to do? Is this valid in DMD 2.057? I get
 an error with it (Unknown Option).

 Mars


-L is dmd's the linker flag option. Anything after that is passed to the 
linker. So -L-l passes -l to the linker:

Let me rephrase that, is this valid for OPTLINK?
Unknown Option : LLIBMYSQL


foo.d bar.lib).

No, in fact I couldn't find how to pass a library search path to 
optlink. It can be added to the sc.ini file, but I couldn't find 
a command line option. -l is an ld flag.

The way I did it is
1) Download C connector from mysql's website, 6.0.2 is version headers 
were made for. Remember you'll need the 32-bit one if you're using DMD 
on Windows.
2) Create the binding functions using extern(System).
3) For Windows, use 'coffimplib libmysql.dll libmysql.lib', and build 
with "PathToFile/libmysql.lib". Example: 'dmd test.d libmysql.lib'
3b) For Linux, just link to libmysqlclient. a with -L"libmysqlclient.a" 
or by just passing path.
4) Make sure that libmysql.dll (for Windows) is in the application 
folder otherwise you'll get errors when trying to run.

 Oh man... that was the problem. The file I used was using extern(C).
 Thought that was okay, it's a C lib after all. Thank you!

 Mars


A number of libraries on Windows use a different calling convention. Any 
functions declared WINAPI or PASCAL in the C headers need to be declared 
either extern(Windows) or, if cross-platform, extern(System).
