[SOLVED] Does RPM build always take the files from ~/rpmbuild?

Issue

Everywhere I have seen on the internet, the default location for the rpmbuild is a user's home directory, ~/rpmbuild. What if I wish to build it in another folder location, say, ~/foo/bar/rpmbuild?

Why is this? What difference would it make if my build location is something else?

EDIT: This means even the ~/rpmmacros file could be anywhere.

Solution

You can build rpms without having to modify or maintain a .rpmmacros file by specifying _topdir in the rpmbuild command line. For example,

rpmbuild --define '_topdir $(RPMBUILD_DIR)' \
    --define 'version $(VERSION)' \
    --define 'release $(RELEASE)' \
    -bb $(PKGNAME).spec

is in one of my Makefiles for an rpm project to build my rpms under ${RPMBUILD_DIR} with the specified version and release numbers from variables. I use this a lot so that I can have multiple rpm-building projects that don't conflict with each other trying to build in the same directory.
