[ILUG] [OT] Autoconf query

[Mel]

This is for anyone that uses autoconf.

When I want to check if a library is available, I put

AC_CHECK_LIB(lib, func)

into configure.in and this works for most libraries such as pthreads

AC_CHECK_LIB(pthreads, pthread_attr_init)

but it doesn't work for WINE. I tried

AC_CHECK_LIB(wine, MAIN_WinelibInit)

I know the function is there and I know the program would work if I didn't
check fo rth library but configure always returns that it's not there. I
checked with nm to be sure and got

[mel at morpheus lib]$ nm -B libwine.a | grep MAIN
00001e20 T MAIN_GdiInit
00001ba8 T MAIN_KernelInit
00001af0 T MAIN_MainInit
00001ec8 T MAIN_UserInit
         U MAIN_WineInit
00002048 T MAIN_WinelibInit
0000adf0 T MAIN_GetLanguageID
0000a8c0 t MAIN_GetProgramName
0000a93c T MAIN_ParseDebugOptions
0000c49c T MAIN_ParseLanguageOption
0000c648 T MAIN_ParseModeOption
0000c6b4 t MAIN_ParseOptions
0000a8a0 T MAIN_Usage
0000c7fc T MAIN_WineInit


so it's defo there. How does AC_CHECK_LIB work and why might it be
returning me garbage?
