Getting SOURCES from dynamic subdirectories

I need to build multiple RPM packages. But it's getting a missing file as it is searching in the /SOURCES/ directory instead of searching in the respective subdirectory. Is there any way to solve it without touching the spec files, with rpm macros?

After executing rpmbuild -bb ~/rpmbuild/SPECS/*.spec getting the following error:

error: File /home/centos/rpmbuild/SOURCES/autoconf-2.69.tar.gz: No such file or directory

Here is my ~/rpmbuild/SOURCES/ tree after symlinking with the development codes:

~/rpmbuild/SOURCES/
├── autoconf -> /home/centos/Project/autoconf/
│   ├── autoconf-2.69.tar.gz
│   ├── autoconf.spec
│   └── config.site
├── autorespond-toaster -> /home/centos/Project/autorespond-toaster/
│   ├── autorespond-2.0.5.tar.bz2
│   ├── autorespond-toaster.spec
│   └── autorespond_utf-8.patch
├── bind -> /home/centos/Project/bind/
│   ├── bind-9.3.1rc1-sdb_tools-Makefile.in
│   ├── bind-9.9.9-P6.tar.gz
│   ├── bind.spec

And ~/rpmbuild/SPECS/ tree:

~/rpmbuild/SPECS/
├── autoconf.spec -> /home/centos/Project/autoconf/autoconf.spec
├── autorespond-toaster.spec -> /home/centos/Project/autorespond-toaster/autorespond-toaster.spec
├── bind.spec -> /home/centos/Project/bind/bind.spec

Solution

I think you should redefine the _sourcedir macro this way:

rpmbuild --define "_sourcedir /home/centos/Project/autoconf" \
    -bb /home/centos/Project/autoconf/autoconf.spec

So this script should do the complete job:

for pkg in autoconf autorespond-toaster bind; do
    rpmbuild --define "_sourcedir /home/centos/Project/$pkg" \
        -bb /home/centos/Project/$pkg/${pkg}.spec
done
