[etherlab-users] problems making etherlab (+ other issues)

[dclark at mmto.org]

Hi Richard,

Yes, this gets us a little closer. I had attempted to put the line, "SHELL
= /bin/bash" at the top of the Makefile, as googling around showed
discussions of Ubuntu's decision to install dash instead of bash as the
standard shell, which didn't work. I'll be interested to know what your
solution for a portable fix will be.

We're now on to another set of issues, however. Florian had provided a
newer version of ethercat (1.5 with -r1817) to fix the e100 driver issue I
had. So initially attempting to make from the 1.6 bundle fails due to it
requiring ethercat 1.4. I had the tarball, 'etherlab-1.3-pre-r550.tar.gz',
which requires ethercat 1.5. Make still fails, however -- terminal output
below:

I have attached config.log for your use, as well. Let me know if you need
more information.
