Hello, sorry for the late reply. About compiling BRL-CAD on IRIX, you said that I could use my own versions of libxml. Would you possibly know what the minimum supported version of libxml/libxslt/libexslt would be? This would be helpful as we may already have a functional port.
Also, where are the pre-built versions of these libraries supposed to be installed? Am I supposed to set BRLCAD_BUNDLED_LIBS equal to the path where I installed these? Could you please clarify this a bit?

I have a couple of questions about the compilation process and hopefully the answers can help me to get it to build - Currently the main problems I seem to have with getting it to build come from libxml. Is it possible to disable the XML module from compiling? The cmake file seems to suggest so but I can't quite tell how. First, check that the CMake variable BRLCAD_BUNDLED_LIBS is at least set to AUTO. Then, install libxml, libexslt, and libxslt (everything which is included in the misc/tools/xmltools directory) from wherever it works. After this, the build shouldn't touch the xmltools directory any more. (Clean up the build directory before your next CMake run.) The directories included in the BRLCAD_BUNDLED_LIBS build are written to the SRC_OTHER_ADDED_DIRS CMake variable. - When cmake runs, it correctly detects the compiled as GCC 9.2 (a port to IRIX). However during the build process the build fails due to a compiler error. The make files generated by cmake are attempting to use a MIPSPro compiler flag (-rdata_shared) even though it detects the compiler as GCC 9.2. Would it be better to use something like GCC 4.2 (I think the last GCC that supported IRIX) or use MIPSPro? Without having tested it, I'm afraid that gcc 4.2 won't work. BRL_CAD uses some recent C and C++ language features. However, you could point CMake to the IRIX gcc to use this instead and see what happens. Regards, Daniel
