While trying to compiling kaffe-1.1.4 with "--with-profiling" support, I am getting the following error when running kaffe.
[bytecode@cross Kaffe]$ ./configure --with-profiling
[bytecode@cross Kaffe]$ make
..........
Making all in test

When "make test" appears kaffe has been executed. "--with-profiling" means compiling kaffe with -pg option of GCC. But why it cannot run.
BTW, does anyone measure Kaffe with gprof? I want to find the performance bottleneck and optimize it.
Please help.
