I can't tell unless you include some of the undefined symbols. BTW, I've updated my egcs-1.1.1-mingw-extra package to include both the required libs and includes (_G_config.h). The linker has a verbose option that helps. Similarly, the compiler has a -H option that shows the includes being included. $ g++ -mno-cygwin -H -c test.c shows the includes. $ g++ -mno-cygwin -Wl,--verbose test.o shows the libraries being linked in (prints loads of output!).. Both of these switches are very useful for debugging a problem like yours. Regards, Mumit -- Want to unsubscribe from this list? Send a message to cygwin-unsubscribe@sourceware.cygnus.com
