Problems Compiling 9.0

[finotti]

I'm trying to build version 9.0 from source under Linux (Debian Unstable/Sid).  The machine has Intel Core i7-8700 CPU and 48GB of RAM.

Below is the end of the compilation:

[twisted-16.3.0.p0] Finished installing twisted-16.3.0.p0.spkg

Error building Sage.



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

during this run of 'make all-start'):



* package: openblas-0.3.6.p0

  log file: /home/finotti/src/sage-9.0/logs/pkgs/openblas-0.3.6.p0.log

  build directory: /home/finotti/src/sage-9.0/local/var/tmp/sage/build/openblas-0.3.6.p0



The build directory may contain configuration files and other potentially

helpful information. WARNING: if you now run 'make' again, the build

directory will, by default, be deleted. Set the environment variable

SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.



make[1]: *** [Makefile:33: all-start] Error 1

make[1]: Leaving directory '/home/finotti/src/sage-9.0'

make: *** [Makefile:13: all] Error 2

The openblas-0.3.6.p0 directory did not seem to have any useful log file.

Any ideas or suggestions?

What about the log file listed:

log file: /home/finotti/src/sage-9.0/logs/pkgs/openblas-0.3.6.p0.log





?

OK, I found the problem!  When trying to compile 8.9 I got a more explicit error message (which I since then "lost" by compiling again) when it also failed due to openblas.

The problem was using

export MAKE="make -j4 -l5.5"

as suggested in the README.md file.  The `-l5.5` parameter was the problem.  Removing it, I could compile 9.0 and now am compiling 8.9.
