I have attached the config.log. Here are excerpts with errors from tests.log: .......... Dashed hope: basic.m:53 ... working callStackSymbols ... if this has failed it is probably due to a lack of support for objective-c method names (local symbols) in the backtrace_symbols() function of your libc. If so, you might lobby your operating system provider for a fix. .......... Testing test03.m... Building base/NSObject/test03.m make debug=yes test03 This is gnustep-make 2.6.6.

OK. I did so. That method begins with: obj = *(id *)args[0]; selector = *(SEL *)args[1]; after it is passed I issued the following gdb commands: (gdb) p selector $19 = (SEL) 0x602400 (gdb) p sel_getName(selector) $20 = -144802851 (gdb) po NSStringFromSelector(selector) name (have no idea why there is the difference) eventually the method calls the SEL typed_sel = gs_find_best_typed_sel (selector); which is the following code: #elif defined (__GNU_LIBOBJC__) { /* The sel_getTypedSelector() function returns a typed selector if there is only one, nul if there are zero or more than one. */ =>return sel_getTypedSelector(sel_getName(sel)); } this last call return 0 (no surprise if the sel_getName(sel) returns an undefined value (see above)) and the exception is triggered.
