ASM support is broken in cmake 2.8.3

[Leon Nardella]

Binary package hint: cmake

I've successfully built vbam (a gameboy advance emulator) with cmake 2.8.2 on Maverick, but when I enabled the backports repository, I got cmake 2.8.3, which can't build it anymore.

This is the output on the console when I run "cmake ."

Found this patch in cmake's git repository which seems to be on the way to 2.8.4.
It's a very simple patch and seems to fix the issue for me. I'm currently in the process of building updated packages for Maverick and Natty for others to test.

[Leon Nardella (leon.nardella)]

There are updated packages in my PPA now. Please test.
ppa:leon.nardella/cmake

[Leon Nardella (leon.nardella)]

People interested in testing may checkout lp:vbam, where I set up a mirror of their svn repo.
I've even set up a daily build of lp:vbam in ppa:leon.nardella/vbam-daily, which is currently building successfully against the cmake package provided in ppa:leon.nardella/cmake.

[Leon Nardella (leon.nardella)]

I got in touch with the Debian maintainer and it's fixed in Debian now.

[FiX (fix-kowalski)]

Installing the afore-mentioned ppa (ppa:leon.nardella/cmake) does not bring any updated cmake package. Is there any other work-around to get the patched version or to revert to 2.8.2?

[Leon Nardella (leon.nardella)]

Are you sure you're on Natty?

[FiX (fix-kowalski)]

No: I am using Maverick, with backports channel enabled. Could you provide a link to the patch, if by some chance this is something that can be patched manually into the CMake scripts (waiting for the updated package).

[FiX (fix-kowalski)]

I disabled "backports" alltogether, so I am back to a working 2.8.2. I will monitor the inclusion of this fix before turning on backports again. Do not consider me as blocked.

[Leon Nardella (leon.nardella)]

There's a package for Maverick in the PPA now.

This bug was fixed in the package cmake - 2.8.3-3

---------------
cmake (2.8.3-3) experimental; urgency=low

  * Install documentation to /usr/share/cmake-data instead as it's the "base"
    package rather than cmake. Also link doc directories to it.
  * The job of replacing directories with symlinks apparently is a tough one.
    Create a symlink manually in the postinst of the affected (!cmake-data)
    packages.

cmake (2.8.3-2) experimental; urgency=low

  [ Kai Wasserbäch ]
  * debian/source/local-options: Added "unapply-patches".
  * debian/watch: Added git-import-orig invocation.
  * debian/gbp.conf: Added, to ensure we use pristine-tar.
  * debian/patches/FindTCL_fix_#600245.diff: Added. (Closes: #600245)

  [ Modestas Vainius ]
  * Install cmake documentation into /usr/share/doc/cmake/ and link doc
    directories of the rest binary packages to it (needs debhelper 7.4.2).
    (LP: #669197)
  * Backport a patch from 2.8.4 to fix ASM support. Thanks to Leon Nardella for
    heads up. (Closes: #608510, LP: #695335)
