gccmakedep - create dependencies in makefiles using 'gcc -M'
gccmakedep [ -sseparator ] [ -fmakefile ] [ -a ] [ -- options -- ] sourcefile ...
The gccmakedep program calls 'gcc -M' to output makefile rules describing the dependencies of each sourcefile, so that make(1) knows which object files must be recompiled when a dependency has changed.
By default, gccmakedep places its output in the file named makefile if it exists, otherwise Makefile. An alternate makefile may be specified with the -f option. It first searches the makefile for a line beginning with
# DO NOT DELETE
or one provided with the -s option, as a delimiter for the dependency output. If it finds it, it will delete everything following this up to the end of the makefile and put the output after this line. If it doesn't find it, the program will append the string to the makefile and place the output after that.
Normally, gccmakedep will be used in a makefile target so that typing 'make depend' will bring the dependencies up to date for the makefile. For example,
SRCS = file1.c file2.c ...
CFLAGS = -O -DHACK -I../foobar -xyz
gccmakedep -- $(CFLAGS) -- $(SRCS)
The program will ignore any option that it does not understand, so you may use the same arguments that you would for gcc(1), including -D and -U options to define and undefine symbols and -I to set the include path.
gcc(1), make(1), makedepend(1).
The version of the gccmakedep included in this X.Org Foundation release was originally written by the XFree86 Project based on code supplied by Hongjiu Lu.
Colin Watson wrote this manual page, originally for the Debian Project, based partly on the manual page for makedepend(1).
