Usage: compile [--help] [--version] PROGRAM [ARGS] | |
Wrapper for compilers which do not understand `-c -o'. | |
Remove `-o dest.o' from ARGS, run PROGRAM with the remaining | |
arguments, and rename the output as expected. | |
If you are trying to build a whole package this is not the | |
right script to run: please start by reading the file `INSTALL'. | |
Report bugs to <bug-automake@gnu.org>. | |
