This article is about how to build rpm packages with the rpmbuild command and a SPEC file. The example is based on SuSE 11.3 x86_64. However, other distributions should work same or similar.
The program
Here is how we create our program, hello world:
cd
mkdir hello
cd hello
cat >main.c <<EOF
#include <stdio.h>
int main()
{
printf("hello world");
}
EOF
The Makefile
To build our program, we need a makefile. Here is how we create it:
cat >Makefile <<EOF
all:hello
hello: main.c
gcc main.c -o hello
install: hello
cp hello /usr/local/bin
EOF
sed -i "s/ /\t/g" Makefile
The SPEC file
cat >hello.spec<<EOF Summary: hello greets the world Name: hello Version: 1.0 Release: 1 License: GPL Group: Applications/Sound Source: hello.tar.gz URL: http://www.staerk.de/thorsten/ Distribution: SUSE Linux Vendor: - Packager: Thorsten Staerk %description hello greets the world %prep %setup %build make %install make install mkdir -p /usr/src/packages/BUILDROOT/hello-1.0-1.x86_64/usr/local/bin cp /usr/local/bin/hello \$RPM_BUILD_ROOT/usr/local/bin/hello %files %defattr(-, root, root) "/usr/local/bin/hello" EOF
Build the rpm
Now we have the SPEC file and the software. Build it with the command
rpmbuild -ba hello.spec
You will find your ready RPM under /usr/src/packages/RPMS.
