Re: [osg-users] problem compiling OSG2.4 on MinGW
Hi Philip, The Find modules distributed as part of OSG with CMake search C:/Program Files/OpenSceneGraph/lib at configure time (not sure why). Because that's where the Win32 binary installer puts the OSG libs and 3rd party libs. It's one of the possible locations where they might be on a system. Unfortunately on Windows there is no system-wide lib path, so all we can do is look in a few possible locations, or hope that the user has defined OSG_LIB_PATH. Otherwise, the user will have to manually specify the path to each lib.

Re: [osg-users] problem compiling OSG2.4 on MinGW
I did that and it passed that problem. Now I'll just keep getting the sources of the missing libraries and compile it myself; I was hoping someone would have all the MinGW compiled osg dependent libraries available on the web.

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