[openblas-0.3.9] Please email sage-devel (​http://groups.google.com/group/sage-devel)

[openblas-0.3.9] explaining the problem and including the log file

[openblas-0.3.9] Describe your computer, operating system, etc.

[openblas-0.3.9] If you want to try to fix the problem yourself, *don't* just cd to

[openblas-0.3.9] /Users/wdj/sagefiles/sage-9.2.rc0/local/var/tmp/sage/build/openblas-0.3.9 and type 'make' or whatever is appropriate.

[openblas-0.3.9] Instead, the following commands setup all environment variables

[openblas-0.3.9] correctly and load a subshell for you to debug the error:

[openblas-0.3.9] (cd '/Users/wdj/sagefiles/sage-9.2.rc0/local/var/tmp/sage/build/openblas-0.3.9' && '/Users/wdj/sagefiles/sage-9.2.rc0/sage' --buildsh)

[openblas-0.3.9] When you are done debugging, you can type "exit" to leave the subshell.

Error building Sage.

The following package(s) may have failed to build (not necessarily

during this run of 'make openblas'):

package: openblas-0.3.9
last build time: Oct 7 14:38

log file: /Users/wdj/sagefiles/sage-9.2.rc0/logs/pkgs/openblas-0.3.9.log

build directory: /Users/wdj/sagefiles/sage-9.2.rc0/local/var/tmp/sage/build/openblas-0.3.9

It is safe to delete any log files and build directories, but they

contain information that is helpful for debugging build problems.

WARNING: If you now run 'make' again, the build directory of the

same version of the package will, by default, be deleted. Set the

environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.

make: * [openblas] Error 1
