ok, I tried ekopath: UCBFAIL indicates problems! /tmp/usbtest/ccos_DP.output: ucbtest UCBFAIL in COS(X) at line 444 for generic /tmp/usbtest/cexp_DP.output: ucbtest UCBFAIL in EXP(X) at line 444 for generic /tmp/usbtest/clib_DP.output: ucbtest UCBFAIL in ceild at line 701 for double /tmp/usbtest/clib_DP.output: ucbtest UCBFAIL in coshd at line 701 for double /tmp/usbtest/clib_DP.output: ucbtest UCBFAIL in floord at line 701 for double /tmp/usbtest/clib_DP.output:UCBFAIL clib_DP.output , 25 out of 25 tests completed /tmp/usbtest/csin_DP.output: ucbtest UCBFAIL in SIN(X) at line 444 for generic only 10 out of 14 show UCBPASS! options: make="make" cpp="cpp -traditional" #cc=gcc cc=/opt/ekopath-bin-4.0.10_pre20110612/bin/pathcc #fcc=gfortran f77=/opt/ekopath-bin-4.0.10_pre20110612/bin/pathf90 opts="-m64 -O2 -pipe -march=k8" -- #163933
