I used it to compile (./configure --disable-shared) GSL 1.12 . Using CFLAGS = -fexception the checking (make check) completed successfully. But using optimization (CFLAGS = -O2 -fexceptions) the testing fails at (first error) make[2]: Leaving directory `/home/Massimo/gsl-1.12/integration' make check-TESTS make[2]: Entering directory `/home/Massimo/gsl-1.12/integration' FAIL: qawc(f459) elist (1.8329242496630777e-015 observed vs 1.8330829482071535e-015 expected) [744] FAIL: test.exe I compiled the source code for GSL 1.12 successfully (well, disregarding the well known montecarlo optimizer bug) with GCC 3.4.5 and GCC 4.2.1. So it seems a new bug of the new GCC compiler (optimizer) in MinGW. I don't know if the same bug is also present in other platforms. I also tested the TDM GCC 4.4.0 (R2 available at http://www.tdragon.net/recentgcc/ ) and I got the same failure using optimization. Is there a way to complete testing instead of stopping at first error? Hop this helps.
