Hello, Maybe someone from the list can help me out. I'm trying to build a project that contains a number of executables, static and shared libraries using cygwin/autotools, but I'm having trouble with libtool. At certain point during the build, the linker returns an undefined reference error: ../lib/.libs/libopenmodeller.a(libenv_io_la-raster_gdal.o)(.text+0xa59): In function `_ZN10RasterGdal6createEPcR6Header': /home/ricardo/wcs/modeller/src/lib/env_io/raster_gdal.cpp:217: undefined reference to `_GetGDALDriverManager' The command that generated this error is: /bin/bash ../../libtool --mode=link g++ -g -O2 -o om_console.exe om_console-om_console.o om_console-occurrences_file.o om_console-request_file.o -L/usr/local/lib -lgdal ../lib/libopenmodeller.la which in turn runs this: g++ -g -O2 -o om_console.exe om_console-om_console.o om_console-occurrences_file.o om_console-request_file.o -L/usr/local/lib /usr/local/lib/libgdal.dll.a /usr/lib/libjpeg.dll.a -ltiff -lpng -lz -L/usr/lib -lpq ../lib/.libs/libopenmodeller.a -L/usr/local/lib -L/usr/local/lib Not sure why gcc doesn't find the symbols in libgdal.dll.a. nm says the symbol is there: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> ~/wcs/modeller/src/console $ nm /usr/local/lib/libgdal.dll.a | grep _GetGDALDriverManager 00000000 T _GetGDALDriverManager 00000000 I __imp__GetGDALDriverManager If I replace the library "/usr/local/lib/libgdal.dll.a" in the command above by "-lgdal", I get my executable compiled. The problem does not happen when I compile the application on a Linux box. Does anyone know what seems to be the problem in my setup? Any help would be greatly appreciated. Regards, Ricardo
