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.

pg_buildext

PG_BUILDEXT(1)						 Debian PostgreSQL infrastructure					    PG_BUILDEXT(1)

NAME

       pg_buildext - Build and install a PostgreSQL extension

SYNOPSIS

       pg_buildext action srcdir target opts

DESCRIPTION

       pg_buildext is a script that will build a PostgreSQL extension in a VPATH way. It supports the configure, build, install, and clean
       actions, and will choose to build for the intersection of versions known in debian/pgversions (versions supported by the package) and in
       /usr/share/postgresql-common/supported-versions (versions supported in this release).

OPTIONS

       action
	   One of configure, build, install, or clean.

       srcdir
	   Where to find the extension sources, including the debian subdirectory.  (Usually $(CURDIR).) If not specified, defaults to the current
	   directory.

       target
	   The target directory where to build the sources, it will get created for you if it does not exist. If the target contains a %v sign, it
	   will get replaced by the specific version of PostgreSQL being built against.  (Usually build-%v.)

       opts
	   %v signs in opts will get replaced as in target.

	   configure
	       Options to pass to the configure script. (Most PostgreSQL extensions do not have a configure script.)

	   build
	       Custom CFLAGS options to use for the build.

	   install
	       Package name to install for. Make will be called with DESTDIR="srcdir/debian/package".

	   clean
	       clean does not take extra options.

USAGE

       As pg_buildext invokes make for the build, install, and clean actions, invocations from debian/rules (which is a makefile) should be
       prefixed with + so the sub-makes can talk with the make jobserver.

EXAMPLE

	 build-stamp:
		 +pg_buildext configure $(CURDIR) build-%v "--libdir=/usr/lib/postgresql/%v/lib --datadir=/usr/share/postgresql-%v-plsh"
		 +pg_buildext build $(CURDIR) build-%v

	 install: build
		 +pg_buildext install $(CURDIR) build-%v postgresql-%v-plsh

	 clean:
		 +pg_buildext clean $(CURDIR) build-%v
