Hi JP, I have done some further experiments and have similar finding to yours. The double linking is caused by applications/CMakeLists.txt and examples/CMakeLists.txt explicitly listing OpenThreads in the TARGET_COMMON_LIBRARIES, and these entries automatically get the 'd' appended to lib names, which conflicts with the OpenThreads.so found by the initial cmake/ccmake .etup.
Take OpenThreads out of the TARGET_COMMON_LIBRARIES list solves the double linking problem, and things still compile fine for me under Linux. I have checked this in as a temporary measure. I'll raise this topic on osg-build w.r.t finding the best way of tackling this issue. Robert. On 3/25/07, J.P. Delport <[EMAIL PROTECTED]> wrote:
Hi, I also saw this double linking problem. It seems to be created by the CMake scripts once one has two versions of libOpenThreads in /usr/local/lib. (maybe the detection script?) If you look at your OSG dir now you should see both OT libs in e.g. applications/osgviewer/CMakeFiles/application_osgviewer.dir/build.make What I had to do to get rid of it was to clean out my /usr/local/lib, then compile OT and then compile OSG when only libOpenThreadsd.so was present. In this case the apps would only be linked to libOpenThreadsd. At first I also thought that this was the problem, but after a restart and clean debug compile I still get the strange errors when starting an app/example. Let me know if I can provide more info. regards jp Robert Osfield wrote: > Hi JP, > > On 3/25/07, Robert Osfield <[EMAIL PROTECTED]> wrote: >> I don't have any explanation for this odd behavior.
