Thanks for persevering. I've decided to introduce a Image::computeNumberOfMipmapLevels(..) static method to replace the use of log2 in the texture classes, and have removed log2 from the include/osg/Math header. Once I have a clean build I'll check in these changes. > to CMAKE_CXX_FLAGS - tried only using some parts but ultimately used all the > flags and added to CMAKE_C_FLAGS too.

Which of the above additions to the compiler flags was required to fix the log2 errors, which the tessellator ones? > I also had to make the change for wsock32.lib to wsock32.a in CMakeLists.txt > in the root of the svn tree so the compile would find the correct library in > Cygwin. > > I also had to make a change for osgviewerMFC in the examples/CMakelists.txt It should be straight forward to disable this example via CMake directives if your building under Cygwin. > so it would not build and had to remove the references for the wxWidgets > (that whole routine could be nicer). What errors do you get with wxWidgets? I presume its installed as CMake should build the osgviewerWX example without it. > Most of the above I think I have reported before and OSG did build an install > but I guess still not enough thread changes in Cygwin as osgconv still hangs > on exit and has to be killed. Curious. osgconv is a single threaded app, one of the ones I'd least expect any problems. My best guess is that there is some issue with destruction of proxy objects that are created on loading of the plugins. Does running osgconv without any parameters fail?
