Thanks for looking at it. I tried to check into it myself quickly, but
xdebug (and xprof) don't appear compilable on my system right now. First
there's a no-brainer:
../../../kaffe/kaffe/xprof/gmonFile.c: In function `writeGmonRecord':
../../../kaffe/kaffe/xprof/gmonFile.c:136: `char' is promoted to `int'
when passed through `...'
../../../kaffe/kaffe/xprof/gmonFile.c:136: (so you should pass `int' not
`char' to `va_arg')

break;
case GRA_ProfilingRate:
*((int *)ghh.prof_rate) = va_arg(args, int);
After fixing that, xdebug still doesn't compile because machine_debug_file
isn't compiled in for some reason - why isn't exactly clear, as
debugFile.c is wrapped with checks for both KAFFE_XPROFILER and
KAFFE_XDEBUGGING. Rather than try to figure that out, I turned also
xprofiling on, but then the compile breaks with:
../xprof/.libs/libkaffexprof.a(xprofiler.o): In function
`enableXProfiling':
/home/jsantala/kaffe-build/kaffe/xprof/../../../kaffe/kaffe/xprof/xprofiler.c:243:
undefined reference to `_gmonparam'
/home/jsantala/kaffe-build/kaffe/xprof/../../../kaffe/kaffe/xprof/xprofiler.c:249:
undefined reference to `_gmonparam'
...etc.
Oh well, I guess it's off to try to figure out makefile magic ;)
