Subject: GSL and MinGW with the GCC 4.4.0
Date: Tue, 23 Jun 2009 21:37:00 -0000 [thread overview]
Message-ID: <4A414B06.6060401@alice.it> (raw)
Dear all,
Platform : Windows XP Sp3 , MinGW latest binutils,make,runtime GCC 4.4.0
MinGW team has just release and official version of the new GCC compiler
(4.4.0). 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.
