Hello,
I tried to build Lapack 3.1.1 using cygwin. Compilation works fine, but
testing reports failures. The g77 flags were -O3 -funroll-all-loops.
For gcc 3.3.3 failures are reported by CEV, CVX, CGV, DGV, SGV, ZGV.
For gcc 3.4.4 failures are reported by CGV, DGV, SGV, ZGV.
As far as the prebuilt binary (lapack 3.0-5)is concerned, I tried to run the
Lapack-3.0 tester against it. The result is:
$ make blas_testing
( cd BLAS/TESTING; make -f Makeblat1 )
make[1]: Entering directory /home/Weronika/LAPACK/BLAS/TESTING'
make[1]: Nothing to be done for all'.
make[1]: Leaving directory /home/Weronika/LAPACK/BLAS/TESTING'
( cd BLAS; ./xblat1s > sblat1.out; \
./xblat1d > dblat1.out; \
./xblat1c > cblat1.out; \
./xblat1z > zblat1.out )
3656 [main] xblat1c 2808 _cygtls::handle_exceptions: Error while dumping
state (probably corrupted stack)
/bin/sh: line 3: 2808 Segmentation fault (core dumped) ./xblat1c >
cblat1.out
7 [main] xblat1z 3096 _cygtls::handle_exceptions: Error while dumping
state (probably corrupted stack)
/bin/sh: line 3: 3096 Segmentation fault (core dumped) ./xblat1z >
zblat1.out
make: *** [blas_testing] Error 139
When lapack test is run, I get
8 [main] xeigtstc 3376 _cygtls::handle_exceptions: Error while dumping
state (probably corrupted stack)
6 [main] xeigtstz 964 _cygtls::handle_exceptions: Error while dumping
state (probably corrupted stack)
Failures are reported by DGV, ZGV.
Best regards,
Cezary Sliwa
