I had a similar problem. Thanks to Dave, Using the shared library for threads that got built while build+installing boost solved my problem. - Raja
Hi, I posted this a while ago but with no response, so I'm trying again. If anyone is using the boost::threads library with gcc & STLPort and has no problems, perhaps they could let me know - at least then I know its worth perservering with (or at least try compiling my example?)
If I try to compile the example below with a makefile (also below), then I get this linker error:
/home/ncain/tmp/ccaK5aes.o(.text+0x4b): In function `main': : undefined reference to `boost::thread::thread[in-charge](boost::function0<void, _STL::allocator<boost::function_base> > const&)'
If I don't use the _STL namespace it compiles. Looking at the libboost libraries, they contain references to _STL stuff, so I assume I compiled them ok (bjam -sTOOLS=gcc-stlport -sBUILD="<stlport-iostream>on" )
Does anyone know what could be wrong? (or how I can change a bjam file to include the /usr/local/include/stlport path? so I could try that)
