I have combined my changes with Matthew Baker's to give a reasonably simple method of building the Xerces-C library using the native transcoder under SGI IRIX 6.5 with MIPSpro 7.30 compilers.
Instructions and changed files can be found at http://www.esc.auckland.ac.nz/People/Students/Nickerso/Xerces-C/index.html The main point to note is that unless you have the -d flag on the runConfigure command, relative paths do not appear to work. i.e. unless you use a debug (or even an optimised debug) library, you always need to specify the absolute URI - file:/path/to/sample/sample.xml - rather than the relative path!! This appears to be the case whether you use the native or the ICU transcoders. Any ideas ??? David.
