Hi Rico,

there is more going on than that. I just disabled all those locks for
testing and nothing changes (funnily it's not even crashing). I will try
to have a look. Rewriting everything so each thread get's
thread-specific datastructures might be more than I am ready to do
though. On the other hand, sounds like a good plan for Christmas.

Best,

Marcin

Hi,
When I run this command "./bjam --with-irstlm=/media/Data/MOSES/irstlm-5.80.06 -j8" in order to link IRSTLM with MOSES, this error message appears:

?...failed gcc.link lm/bin/model_test.test/gcc-4.7/release/debug-symbols-on/link-static/threading-multi/model_test......skipped <plm/bin/model_test.test/gcc-4.7/release/debug-symbols-on/link-static/threading-multi>model_test.run for lack of <plm/bin/model_test.test/gcc-4.7/release/debug-symbols-on/link-static/threading-multi>model_test......failed updating 46 targets......skipped 124 targets......updated 763 targets...


Does any one have any idea in order to debug?
Regards,
Benyamin?
