[osg-users] problem compiling OSG2.4 on MinGW

[王韬]

I have compiled OSG on devcpp , and OK.

I transform all .lib to .a like these steps:
 pexports zlib1.dll > zlib1.def
 dlltool -k -d zlib1.def -l libzlib1.a
or like these steps
 reimp -d libmysql.lib
 dlltool -k -d libmysql.def -l libmysql.a

and under CMAKE,choose these .a files instead of .lib files.

I hope i have explained clearly.i am poor in english.

Hi,

  I'm having a "cannot find -ljpeg" problem compiling OSG2.4 on MinGW, 
but when I do a ls on C:/Program Files/OpenSceneGraph/lib, I see:

C:/Program Files/OpenSceneGraph/lib/libjpeg.lib
C:/Program Files/OpenSceneGraph/lib/libjpegD.lib

(these are Michael's Prebuilt OSG binaries for Windows.) Do you know 
what I did wrong?

Thanks,

Linh
