If you provide us the output of the make command we can be more helpful. My suspicion is you have both a "main.c" and a "main.cpp" in your directory. Since you don't specify which source file should be used to build the object file, make uses rule precedence and chooses to build "main.c". If you're saying that make is actually compiling 'main.cpp' into 'main.o' and it's using 'cc' as the compiler, I'd say that's not possible unless there is something else going on that you haven't described. _______________________________________________ Help-make mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-make
