Changes to to workaround broken boost packages

Component: Packaging Version: 1.0.0
Keywords: Cc:


To package deluge=1.0.0 for Foresight I needed to change to workaround a broken boost package. The changes made could help other packagers build Deluge.

Firstly /usr/lib/ only exists when building for x86, for x86_64 it is in /usr/lib64, I suggest changing the logic to use LIBDIR rather than /usr/lib explicitly.

Secondly all the boost libraries *except* boost_thread are available as both -mt and non -mt. To workaround that I changed it explicitly in _libraries. However combined with the first problem however this failed unexpectedly building for both arches - it tried to use boost_thread-mt-mt. So I added a further check before appending -mt.

Patch to add libdir and check for libraries ending -mt

comment:1 Changed 12 years ago by pscott@…

Forgot to add information about automatic detection. Foresight /etc/issue is empty but /etc/distro-release contains Foresight Linux.

Further, even with those two changes the package still needs to explicitly change _libraries to use boost_thread-mt. However with those changes there is no unexpected outcome of doing so, ie boost_thread-mt-mt.

Strictly speaking that's because of the LIBDIR change but I think it still makes sense to check if it ends in -mt 'just in case'.

I agree with the reporter, however I disagree with his suggestion that this is due to a "broken package". It's just bad detection logic on the part of deluge. The part about libdir is a no-brainer, but the second part is equally wrong on Deluge's side. It should not assume that would always just be a symlink to , which appears to be the current underlying assumption. On Mandriva, like Foresight, the boost packages contain both single-threaded and multithreaded versions of the library; so if you just use , you are getting a single-threaded boost, not the multithreaded one.

I know this logic has been changed zillions of times, but the current setup just ain't right.

For now in Mandriva I've changed it to a positive test for , using LIBDIR:

# Modify the libs if necessary for systems with only -mt boost libs

  • if not os.path.exists(
  • os.path.join(sysconfig.PREFIX, "lib", "")):
  • # It's likely that this system doesn't have symlinks setup

+ if os.path.exists(os.path.join(sysconfig.get_config_vars()LIBDIR?, \ + '')):

# So add '-mt' to the libraries for lib in _libraries:

if lib[:6] == "boost_":

so if it *does* find a , it adds -mt to all the lib names.

The lack of would torpedo this for Foresight, I guess, but at least it'd be closer.

Bah, I forgot Trac eats patches for breakfast. I'll attach it.

Mandriva patch

I should have been clearer, Foresight has a but no Looking for and appending -mt if it exists ought to work on Foresight.

Looking at it again the second part of my patch is redundant, left over from an earlier attempt to build for both architectures.

  • Milestone set to 1.0.1
  • Resolution set to fixed
  • Status changed from new to closed

I have committed [3867] to hopefully fix this. The logic will not check for each boost lib's multithreaded version (-mt) first and if not available it will use the regular non mt lib. It does this for each boost lib.

Let me know if there are still issues.

[3867] built fine on Foresight.
