To generate a debian from fedora.
1. Prepare the big patch
On fedora do
> rpmbuild -bp rocm-compilersupport.spec
This will produce something like
~/rpmbuild/BUILD/rocm-compilersupport-19-build/llvm-project-rocm-6.4.0
Go to the dir and untar the original source
> cd ~/rpmbuild/BUILD/rocm-compilersupport-19-build/
> mkdir a
> cd a
> tar xf ../../../SOURCES/rocm-compilersupport-6.4.0.tar.gz
Make a copy for later debian
> tar cf llvm-project-rocm_6.4.0.orig.tar llvm-project-rocm-6.4.0
> gzip llvm-project-rocm_6.4.0.orig.tar
Make/move original source
> cd ..
> cp -r a/llvm-project-rocm-6.4.0 llvm-project-rocm-6.4.0.orig
Remove the unneeded directories
> cd llvm-project-rocm-6.4.0.orig
> rm -rf {bolt,flang,libc,libclc,lldb,llvm-libgcc,mlir,polly,third-party}
Remove fedora prep cruft
> cd llvm-project-rocm-6.4.0
> rm *.sed prep.sh
Make the patch
> diff -ruN llvm-project-rocm-6.4.0.orig llvm-project-rocm-6.4.0 > patch.diff
Change the fedora path to a debian path
> sed -i -e 's@usr/lib64/rocm/@usr/lib/rocm/@' patch.diff
Copy this patch to debian/patches
2. Prepare the build area
On ubuntu/debian run
> setuptmp.sh
3. try out a build
> cd ~/b/rocm-compilersupport/llvm-project-6.4.0
> debuild -us -uc
When there is an error, check if the cmake config options match the specfile.
