libtorrent-svn compiling trouble

kfour · 2009-12-29 17:45:25

Using gcc 4.4.2-4
libtorrent-svn revision 1119

I get this error when trying to build the package from AUR:
checking signedness of mincore parameter... configure: error: failed, do *not* attempt fix this with --disable-mincore unless you are running Win32.

The libtorrent wiki specifically addresses this problem here: http://libtorrent.rakshasa.no/wiki/CompilationHelp

Problem: Most likely, no C++ compiler is installed.
Solution: Install g++ or any other competent C++ compiler.
In most cases this error message is very misleading and indicates a general inability to compile C++ code rather than a specific problem with the signedness of the mincore parameter.

I do have a C++ compiler installed. I have not been able to find any information on issues with libtorrent-svn and my compiler. What are my options for getting this compiled? Does anyone know what might be the problem? Thanks

Whate versions of gcc and c++ compiler do you have installed? And do the versions match? if not then update to make them run the same version. That should take care of your issue :-)

Edit: Forgot to mention that glibc needs to be the same version as gcc and your c++ (assuming it's g++) compiler :-)

maybe it can't find it? What does 'g++ --version' give you?

post config.log

I'm not quite sure I understand why that command would do anything to help other than compare the versions of the three packages i mentioned.
Also wouldn't it be quite strange for it not to be able to find the c++ compiler? If it is g++, I mean unless it's been manually it should just be at the standard place, or unless one has manually edited files pointing to it. Or am I mistaken about it?

I copied the parts of config.log that seemed relevant. If I missed something important I will just post the entire thing, but it was fairly large.

configure:16610: error: failed, do *not* attempt fix this with --disable-mincore unless you are running Win32.

g++ --version and gcc --version returns: g++ (GCC) 4.4.2 20091208 (prerelease)

Also, forgot to add: glibc shows as 2.11.1-1. Is this correct? zeerak mentioned that glibc/gcc/g++ all need to be the same version...maybe this is whats going on?

edit #2: Ok so I switched repositories just to see if that helped. Apparently the one I was using was a tiny bit behind the unixheads one, so I updated to the new 2.6.32.2 kernel and headers. Tried to rebuild libtorrent-svn with no difference, still fails with the same error.

I used a bit of a workaround to solve this problem. I still have no idea why its doing what its doing but its not critical to solve anymore. I appreciate everyone's input.
