Hello Everyone,
I figured it may be useful to make a summary of the issues that I
encountered as I made a conda package for Scilab. The information already
exists in a couple of other threads but is scattered accross many messages.
Hopefully, the core team will be able to resolve some of these for the next
version of scilab.
*1) *Only scilab-cli was included in the conda package, and not the
graphical interface.
The reason is that scilab does not build with *openjdk* 11, and requires an
older version that has not been packaged for conda.
*2) *scilab does not build on OS X when using the *--without-matio* option.
The build ends with the following error:
ar: no archive members specified
usage: ar -d [-TLsv] archive file ...
ar -m [-TLsv] archive file ...
ar -m [-abiTLsv] position archive file ...
ar -p [-TLsv] archive [file ...]
ar -q [-cTLsv] archive file ...
ar -r [-cuTLsv] archive file ...
ar -r [-abciuTLsv] position archive file ...
ar -t [-TLsv] archive [file ...]
ar -x [-ouTLsv] archive [file ...]
make[1]: *** [libscimatio-algo.la] Error 1
Fortunately, we were able to package matio for conda-forge as well, so this
error does not impact us anymore. However, I do think that we should be
able to use that option.
*3)* We cannot build headless scilab on OS X
It seems that we cannot build scilab with the *--without-gui *option on OS
X. The build fails over the symbol *_initMacOSXEnv* not being found.
Stephane Mottelet proposed to apply a patch to the generated makefile after
the configure stage to overcome that issue.

This patch allows scilab-cli to build completely on OS X, but then scilab
fails to start at runtime (the conda recipe has a sanity check that we can
run the executable)

Stéphane advised to use the *--enable-code-coverage=no* option which does
not solve the issue unfortunately.
Hopefuly, this summary will be useful for others.
Best,
Sylvain
