Hi,
I'm trying to run testlapack example from cython-notur09 on OS X 10.6.
First, while compiling I faced with following error
gcc -L/sw64/lib -bundle -L/sw64/lib/python2.6/config -lpython2.6
build/temp.macosx-10.4-i386-2.6/lapack.o
-L/Applications/development/sage//local/lib -llapack -lf77blas -lcblas
-latlas -o lapack.so -g
Undefined symbols:
"_clapack_dgesv", referenced from:
_dgesv in lapack.o
_dsolve in lapack.o
ld: symbol(s) not found
So I changed clapack_dgesw in lapack.pxd to dgesw and successfully
build it against SAGE (sage-4.2.1-OSX10.6-Intel-64bit-i386-Darwin.dmg)
but when I run testlapack.test() python froze, using 100% of CPU,
below is debuging info.
>>> tl.test()
test start
^C
Program received signal SIGINT, Interrupt.
0x00000001005280a4 in dgesv (__pyx_v_Order=CblasRowMajor, __pyx_v_N=3,
__pyx_v_NRHS=1, __pyx_v_A=0x7fff5fbfdda0, __pyx_v_lda=3,
__pyx_v_ipiv=0x7fff5fbfde10, __pyx_v_B=0x7fff5fbfddf0, __pyx_v_ldb=3)
at lapack.c:775
775 static int dgesv(enum CBLAS_ORDER __pyx_v_Order, int __pyx_v_N,
int __pyx_v_NRHS, double *__pyx_v_A, int __pyx_v_lda, int
*__pyx_v_ipiv, double *__pyx_v_B, int __pyx_v_ldb) {
(gdb) exit
I was also tried to build it against Mac OS X accelerated framework
and the result is the same, while on linux this example works fine.
Any suggestions what's wrong?
Regards,
Max Mayzel
