Hi,
I'm using Karmic version x64, boost lib version 1.38
When building boost.thread project with flag Boost_USE_STATIC_LIBS ON, I get the errors listed below, while if I build them with
Boost_USE_STATIC_LIBS OFF, everything works fine. I mean not only builds, but it executes as it should.
Btw, the Karmic is fresh install (no upgrade). CMake, boost 1.38 and gcc are from ubuntu repos. Everything worked just fine with Jaunty (with boost 1.35 actually). Is this the boost problem, or something else?
To reproduce the above problem, just take any boost.thread tutorial and write CMakeLists.txt as described in boost docs.
best regards,
fantaz

I get the same on x86 Karmic. I've attached a sample which is nothing but a simple cpp calling boost::
