[llvm-dev] How to create Debian packages for release 3.9.0

Mon Dec 12 04:59:09 PST 2016

As a sidenote, I'd like to note that even for a non-specific release
the build process is flawed. When building the 3.9 branch without
being specific:

 $ debcheckout svn://anonscm.debian.org/svn/pkg-llvm/llvm-toolchain/

 $ cd llvm-toolchain/branches/

 $ sh 3.9/debian/orig-tar.sh release_39

 $ sh unpack.sh
 tar (child): llvm-toolchain-snapshot_3.9_3.9~svn288847.orig.tar.bz2:
Cannot open: No such file or directory
 tar (child): Error is not recoverable: exiting now
 tar: Child returned status 2
 tar: Error is not recoverable: exiting now

 $ ls *.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig-clang.tar.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig-clang-tools-extra.tar.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig-compiler-rt.tar.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig-lldb.tar.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig-lld.tar.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig-polly.tar.bz2
 llvm-toolchain-3.9_3.9~svn288847.orig.tar.bz2

I.e. the assumed name part 'snapshot' is not there. After removing the
'snapshot_' part from all filenames in the script, the unpacking
works.

Then, as a next step, the creating of symlinks fails due to the
filenames having the major version number in it twice (whereas the
script assumes it to be only once). After modification this works too.

Then, the next step further down the line the patching step (partly) fails:

The build itself also fails, probably due to the failing patch step:

Again, is there anyone who can help me build the debian packages for
Clang-3.9.0?

Thanks in advance, best regards,
