====== How do I solve the "Argument list too long" error when building libsmm? ======

The libsmm build process involves compiling many small (versions of) matrix multiplication kernels and testing them.  For some shells / settings, the makefile may generate lists of arguments that are too long, and you will see errors like:

<code bash>
make: execvp: /bin/sh: Argument list too long
</code>

This most likely occurs if you are building the library interactively (i.e. not through a batch system).  The workaround is to to use the 'batch / workload manager' option with a null submission command:

<code bash>
./generate -c config/linux.intel -j 100 -w none -t 24 tiny1
</code>

Here the ''-w none'' option means using the null submission command, and  ''-j 100'' splits the build into 100 separate stages.  Increase the value of the ''-j'' option until you no longer hit the ''Argument list too long'' error.
