Hi, OS: cygwin uptodate Boost: 1.28 C++ comp: g++ 2.95.3-5 After what appears like a warning | error free compilation of the thread library. I'm trying to compile the examples, like this: $ g++ -I/data/boost_1_28_0 -o monitor monitor.cpp /data/boost_1_28_ 0/libs/thread/build/bin/libboost_thread.lib/gcc/release/runtime-link- static/threading-multi/libboost_thread.lib Which compiles fine, however when trying to run the example, I get: $ ./monitor.exe Segmentation fault (core dumped) This happening with all the examples, I'm guessing that I must be doing something wrong... =:-D At the same time I'm doing not doing anything particularly wacky so if someone could point my obvious mistake. Do I need to link against boost_threadmon also? Tia, Christophe
