I would like to use sarl3 ( griff -dot- sourceforge -dot- net ) for my degree thesis, but i had some problem in installing it. I'm using arch linux, i installed all the required package, but i get some error with ruby (i tried with ruby 1.8 and 1.9, but the error is still there)

first the "make" had some problem to find the ruby.h so I set the ruby/build_deps.mak with the correct path for ruby.

the next problem i had:
(the <?> are < ' >)

In file included from sarl_string_table.cpp:2:
sarl_bit_set.h:23: error: variable or field ?sarl_finalize_bit_set? declared void
sarl_bit_set.h:23: error: ?GC_PTR? was not declared in this scope
sarl_bit_set.h:23: error: ?GC_PTR? was not declared in this scope
make[1]: *** [sarl_string_table.o] Error 1
make[1]: Leaving directory `/home/ivan/workspace/sarl3-0.9'
make: *** [build] Error 2




i solved it editing my gc.h file, with this:

#ifndef GC_PTR
#define GC_PTR void*
#endif





and the previous error was solved, but now i get a new error about ruby:
