Hi, I'm compiling GiNaC 1.0.9 with gcc3.1, and everything seems to go ok, no error messages from 'make'. But 'make check' - which also compiles fine - fails on all three tests. CLN tests ran fine. Any ideas? Thanks, Will make[2]: Entering directory `/home/will/tmp/GiNaC-1.0.9/check' GiNaC will now take an exam with specific input (like a pupils' exam): examining several historic failures just out of paranoia.............. passed examining consistency of numeric types....../run_exams: line 3: 27225 Aborted ./exams 2>exams.out cmp: EOF on exams.out FAIL: run_exams GiNaC will now run through some rather costly random consistency checks: checking consistency of numeric types.. passed checking consistency of symbolic functions.... passed checking symbolic matrix manipulations..... passed checking linear solve....../run_checks: line 3: 27249 Aborted ./checks 2>checks.out cmp: EOF on checks.out FAIL: run_checks GiNaC will now run through some basic timings: timing commutative expansion and substitution.... passed size: 25 50 100 200 time/s: 0.01 0.04 0.19 0.88 timing Laurent series expansion of Gamma function./run_times: line 3: 27277 Aborted ./times 2>times.out cmp: EOF on times.out FAIL: run_times =================== 3 of 3 tests failed =================== make[2]: *** [check-TESTS] Error 1 make[2]: Leaving directory `/home/will/tmp/GiNaC-1.0.9/check' make[1]: *** [check-am] Error 2 make[1]: Leaving directory `/home/will/tmp/GiNaC-1.0.9/check' make: *** [check-recursive] Error 1 __________________________________________________ Do You Yahoo!?
