When Building gcc for vxWorks, do I need to specify the --enable-threads=vxworks ?? I did included that in my configure command, but when compiling, it tries to compile the file vxLib.c which seems to use definitions of MACROS and types that are defined in the vxWorks include files that comes in the Wind Rivers distribution of vxWorks. Do I need to include in the make, a way of seeing the Wind Rivers include files ? Where would I add the "-I with the path to the wind rivers files" if that is what it takes to be able to compile ? Thanks, Jose
