Hello

I am very new mac user, and I struggling with altlas and cblas. I have installed atlas in Darwin Ports, and downloaded cblas for netlib.

Compilation goes smoothly, with parameters
BLLIB = -L/opt/local/lib -latlas
CC = gcc
FC = gfortran
LOADER = $(FC)
CFLAGS = -v -O0 -DADD_ -I/Users/likask/MyBuild/src/CBLAS/src -Wall
FFLAGS = -v -O0 -Wall -I/Users/likask/MyBuild/src/CBLAS/src

However after compilation I can not pass tests,
kiss:testing likask$ gdb ./xccblat1
(gdb) set env DYLD_INSERT_LIBRARIES /usr/lib/libgmalloc.dylib
(gdb) r

I have used -framework Accelerate insted atlas with similar result.

I know that cblas is included in accelerate framework, but for similar reason it not working with my code. I have segmentation fault. I tested my code on linux on various platforms and it works fine, no leaks.

I hope it is simple trick to solve this problem. I have Mac OS X 10.5.6 with Xcodes 3.1

I hope for some help, regards,
Lukasz
