libmysql and mingw
Daniel Boyd
In my latest attempt, I downloaded this file:
http://devpaks.org/details.php?devpak=105
In ProjectCenter, I added libmysql.a to my libraries. Then, I added
the include directory in the project inspector.
Here is the relevant snippet of my GNUmakefile.preamble generated by
ProjectCenter:
# Additional include directories the compiler should search
ADDITIONAL_INCLUDE_DIRS += -Ic:/GNUstep/libmysql-5.0.5-1sid/include
# Additional library directories the linker should search
ADDITIONAL_LIB_DIRS += -LC:/GNUstep/libmysql-5.0.5-1sid/lib
# Additional GUI libraries to link
ADDITIONAL_GUI_LIBS += -lmysql
Here are some of the errors I'm getting when I try to compile my
program: (note, this source compiles in Linux)
$ make
This is gnustep-make 2.4.0. Type 'make print-gnustep-make-help' for help.

I had a quick look at the logs, and couldn't see anything that seemed
related to GNUstep.
Can you use libmysql without gnustep-make ?
You may want to try creating a simple .c file that uses your libmysql
and compile/link it with GCC directly. If that doesn't work, you know
there is some basic problem with the libmysql you're using. Maybe you
need it packaged differently for MinGW - or you'd need to ask the people
who packaged it for help or instructions.
If that works and it only doesn't work when you compile/link it using
gnustep-make, then there obviously is a problem with gnustep-make; you
may want to compare the gcc command line that works with the one used
by gnustep-make (which you can see by using 'make messages=yes') and see
if you can spot what is the troublesome compiler/linker flag. Of
course if this is the case, please come back with more logs/information
and I'll see if I can help.
I hope this provides some suggestions on how you can move forward.
Thanks
