Top Forums UNIX for Beginners Questions & Answers Help running a Makefile from within a .sh script? Post 303005280 by Scott on Monday 16th of October 2017 01:18:44 PM

Arghh... really doesn't help that I had a file called makefile in my directory, which make was using instead of Makefile Smilie

Code:
populateMFiles() {
#echo '.PHONY: all clean build
echo 'clean:
        rm -rf cfile.c cfile.out
build:
        gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build'
}

This does work fine, as far as I can see, so it would help to see the actual make error, not the one your script is displaying.

Saying nothing as to the rest of your code because I haven't read it, it would be slightly cleaner using cat instead of echo to print the Makefile and C file.

e.g.
Code:
populateMFiles() {
cat << EOF
clean:
        rm -rf cfile.c cfile.out
build:
        gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build
EOF
}

Code:
$ functions
populateMFiles() {
cat << EOF
clean:
	rm -rf cfile.out
build:
	gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build
EOF
}

$ cat cfile.c
int main( void ) {
  printf( "%s", "Hello world!\n" );
  return 1;
}

$ populateMFiles > Makefile

$ cat Makefile
clean:
	rm -rf cfile.out
build:
	gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build

$ make all
rm -rf cfile.out
gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out

$ ls cfile.out
cfile.out

$ ./cfile.out
Hello world!

Your makefile may remove the cfile.c file, so you need to run "populateCFiles" every time before you run make (as clean is the first rule), make all or make clean.

dh_auto_clean

DH_AUTO_CLEAN(1)						     Debhelper							  DH_AUTO_CLEAN(1)

NAME

       dh_auto_clean - automatically cleans up after a build

SYNOPSIS

       dh_auto_clean [buildsystemoptions] [debhelperoptions] [--params]

DESCRIPTION

       dh_auto_clean is a debhelper program that tries to automatically clean up after a package build. It does so by running the appropriate
       command for the build system it detects the package uses. For example, if there's a Makefile and it contains a distclean, realclean, or
       clean target, then this is done by running make (or MAKE, if the environment variable is set). If there is a setup.py or Build.PL, it is
       run to clean the package.

       This is intended to work for about 90% of packages. If it doesn't work, or tries to use the wrong clean target, you're encouraged to skip
       using dh_auto_clean at all, and just run make clean manually.

OPTIONS

       See "BUILD SYSTEM OPTIONS" in debhelper(7) for a list of common build system selection and control options.

       -- params
	   Pass params to the program that is run, after the parameters that dh_auto_clean usually passes.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
