I would like to use sarl3 [Griff - + Compiling Sarl3](http://griff.sourceforge.net/sarl3_compiling.html) 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: sarl\_rb\_get\_object.h:7: error: ?VALUE? does not name a type sarl\_rb\_get\_object.h:8: error: variable or field ?sarl\_set\_ruby\_object? declared void sarl\_rb\_get\_object.h:8: error: ?VALUE? was not declared in this scope sarl\_rb\_get\_object.h:8: error: expected primary-expression before ?void? sarl\_rb\_get\_object.cpp:19: error: ?VALUE? was not declared in this scope sarl\_rb\_get\_object.cpp:20: error: ?VALUE? was not declared in this scope sarl\_rb\_get\_object.cpp:20: error: template argument 2 is invalid sarl\_rb\_get\_object.cpp:20: error: template argument 1 is invalid sarl\_rb\_get\_object.cpp:21: error: template argument 2 is invalid sarl\_rb\_get\_object.cpp:21: error: template argument 5 is invalid sarl\_rb\_get\_object.cpp:21: error: invalid type in declaration before ?;? token sarl\_rb\_get\_object.cpp: In function ?void sarl\_free\_ruby\_object(void\*)?: sarl\_rb\_get\_object.cpp:28: error: request for member ?erase? in ?global\_ptr\_map?, which is of non-class type ?SarlRubyPtrMap? sarl\_rb\_get\_object.cpp: At global scope: sarl\_rb\_get\_object.cpp:31: error: ?VALUE? does not name a type sarl\_rb\_get\_object.cpp: In function ?int sarl\_exists\_ruby\_object(void\*) ?: sarl\_rb\_get\_object.cpp:54: error: expected initializer before ?it? sarl\_rb\_get\_object.cpp:55: error: ?it? was not declared in this scope sarl\_rb\_get\_object.cpp:55: error: request for member ?end? in ?global\_ptr\_map?, which is of non-class type ?SarlRubyPtrMap? sarl\_rb\_get\_object.cpp: At global scope: sarl\_rb\_get\_object.cpp:59: error: variable or field ?sarl\_set\_ruby\_object? declared void sarl\_rb\_get\_object.cpp:59: error: ?VALUE? was not declared in this scope sarl\_rb\_get\_object.cpp:59: error: expected primary-expression before ?void? make[2]: \*\*\* [sarl\_rb\_get\_object.o] Error 1 make[2]: Leaving directory `/home/ivan/workspace/sarl3-0.9/ruby' make[1]: *** [build] Error 2 make[1]: Leaving directory `/home/ivan/workspace/sarl3-0.9/ruby’ make: \*\*\* [build] Error 2 so what shell i do? 😑 thanks, Ivan ---
