gccmakedep - create dependencies in makefiles using 'gcc -M'
program calls 'gcc -M' to outputmakefile
rules describing the dependencies of eachsourcefile
(1)knows which object files must be recompiled when a dependency has changed.
By default,gccmakedepplaces its output in the file namedmakefileif it exists, otherwiseMakefile.An alternate makefile may be specified with the-foption.It first searches the makefile for a line beginning with
# DO NOT DELETE
or one provided with the-soption, as a delimiter for the dependency output.If it finds it, it will delete everything following this up to the end ofthe makefile and put the output after this line.If it doesn't find it, the program will append the string to the makefileand place the output after that.
will be used in a makefile target so that typing 'make depend' will bringthe dependencies up to date for the makefile.For example,
SRCS = file1.c file2.c ... CFLAGS = -O -DHACK -I../foobar -xyz depend: gccmakedep -- $(CFLAGS) -- $(SRCS)
The program will ignore any option that it does not understand, so you mayuse the same arguments that you would forgcc
options to define and undefine symbols and-I
to set the include path.
- Append the dependencies to the file instead of replacing existingdependencies.
- Filename.This allows you to specify an alternate makefile in whichgccmakedepcan place its output.Specifying lq-rq as the file name (that is,-f-)sends the output to standard output instead of modifying an existing file.
- Starting string delimiter.This option permits you to specify a different string forgccmakedepto look for in the makefile.The default is lq# DO NOT DELETErq.
- -- options --
- Ifgccmakedepencounters a double hyphen (--) in the argument list, then anyunrecognized arguments following it will be silently ignored.A second double hyphen terminates this special treatment.In this way,gccmakedepcan be made to safely ignore esoteric compiler arguments that mightnormally be found in a CFLAGSmakemacro (see theEXAMPLEsection above).-D,-I,and-Uoptions appearing between the pair of double hyphens are still processednormally.
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 formakedepend(1).
