Does using gdb get you any more information?

[cschilbe]

Like this?
$ gdb rtorrent
GNU gdb (GDB) 7.6.1

[cschilbe]

Does this help?

First you should brew update and then reinstall this stuff, your Homebrew is ~4 months old.

[cschilbe]

I just installed it today. brew update said everything was up to date. Just did another update and took me from 0.9.4 to 0.9.5:
$ brew --config
HOMEBREW_VERSION: 0.9.5

[cschilbe]

Same issue after update

[cschilbe]

macports install worked. Let me know if there are any other details I can gather.

[adamv]

Which macports version did you install, 0.9.2 or 0.9.3-devel?

[adamv]

We went to 0.9.3 in #19199 but the homepage doesn't list it as a stable version; perhaps we should revert.

[cschilbe]

macports installed 0.9.2 but I also tried installing that one with homebrew and had the same seg faults.

[ghost]

This still occurs. I may have found a way that seems to work pretty often. If you source bashrc and then run rtorrent it seems to work.

$ source ~/.bashrc
$ rtorrent

Maybe it can help narrow down the problem?

[astrashe]

I have the same issue. I don't know how to use gdb, but I'm willing to follow instructions if anyone wants to tell me what to do.

Here's my homebrew setup:

$ brew --config

Here's what I get when rtorrent crashes:

Still seeing this on completely up-to-date system. I ran under lldb, as gdb wasn't available.

[jon@lappy ~]$ lldb rtorrent

This bug is probably a dupe of #25219

[astrashe]

I finally got rtorrent to work by building gcc 4.9 and using that to build rtorrent.

[adamv]

Some movement upstream: rakshasa/libtorrent#47

[mistydemeo]

The C++11 branch is still not stable, and the diff is quite large. Sounds like it'll move closer to stability after the next stable release (which hasn't happened yet).

[adamv]

I updated rtorrent and libtorrent in #29460 and am able to launch rtorrent without a segfault, though I'm not testing its functionality.

[adamv]

Anyone still having this issue with clang, please brew update and try these new versions. Will close this shortly if there is no response.

If there are still problems, willing to add fails_with :clang until upstream fixes the issue.

[ghost]

I seem to still get segfaults with libtorrent 0.13.4, rtorrent 0.9.4.

Now it's worse-- downloading torrents causes a segfault in addition to random segfaults on launch.

[bconway]

Was working great on Mountain Lion previously, updated today and segfault on start.

[ghost]

I reverted to previous version, at least only segfaults sometimes on start.

[bconway]

Rebuilt with today's update (sans libsigc++) and still segfaults on start with Mountain Lion.

[astrashe]

I built rtorrent with homebrew and gcc 4.9 and it's been rock solid on Mavericks. Would it be possible to change the formula so that it uses another compiler by default?

I know that's a huge dependency to introduce, but it does work.

[adamv]

Adding fails_with :clang gives me:

Warning: rtorrent dependency libtorrent was built with a different C++ standard
library (libstdc++ from clang). This could cause problems at runtime.

Though if this works when built with GCC I'll push a change to add that.

[bconway]

Thanks. New build starts on Mountain Lion okay, but immediately segfaults when trying to load a magnet link.

Making the same change as the commit above to libtorrent yielded a (thus far) stable rtorrent on Mountain Lion.

[ainstushar]

@adamv So does it mean that compiling libtorrent with gcc fixes all of the issues? Can you tell us how to do that? (not really a developer). I have installed gcc but I am not sure how to tell libtorrent to use gcc. :(

[adamv]

@ainstushar if you brew update, then brew rm libtorrent rtorrent and reinstall, it will build in a way that @bconway reports as working so far.

[ainstushar]

@adamv Perfect! It works exactly as it should. Thanks for pushing out updated formula for libtorrent.

[adamv]

Provisionally calling this fixed for now.

[bconway]

All's working here, thanks.

[ainstushar]

Looks like this issue is back. Upon installing rtorrent 0.9.4 and libtorrent 0.13.4 (mavericks), it gives this warning:

Warning: rtorrent dependency libtorrent was built with a different C++ standard
library (libstdc++ from gcc-4.8). This could cause problems at runtime.

and upon running rtorrent, I get:

dyld: Symbol not found: __ZNSt3tr18__detail12__prime_listE
  Referenced from: /usr/local/lib/libtorrent.18.dylib
  Expected in: /usr/lib/libstdc++.6.dylib
 in /usr/local/lib/libtorrent.18.dylib
Trace/BPT trap: 5

Any tips on fixing this?

[bconway]

I ran into the same thing this week with upgrading to Mavericks. It'll fix itself if you do:

brew reinstall libtorrent --build-from-source

In this case, I think the issue is that the Mavericks bottle for libtorrent is bogus, but it's the default install.

[ainstushar]

Yep. Works great now. :)

[ghost]

I can no longer install rtorrent. I am on Yosemite now. I get the error "couldn't understand kern.osversion `14.0.0'".

[zg]

I was having the same issue on Mavericks and went with what @bconway most recent post, and now rtorrent works.

Thank you!

[mrknmc]

Just thought I'd add to this, the following combination of both suggestions here worked for me on Yosemite:

brew reinstall libtorrent --build-from-source --cc=gcc-4.9
brew install rtorrent --cc=gcc-4.9

[workmanw]

I recently had this problem and the solution was a combination of things listed here.

First I had to do:

brew update
brew rm libtorrent rtorrent

Then:

brew reinstall libtorrent --build-from-source --cc=gcc-4.9
brew install rtorrent --cc=gcc-4.9

Simply doing the later without the former did not fix my problem. I don't know why, but it didn't. Anyways, just commenting in hopes that it might help someone else.
