[erlang-questions] Cross-compiling tests with quoted ENV vars

[Matt Lewandowsky]

Hello,

I am attempting to cross-compile OTP for a new platform, with a new 
$ERL_TOP/xcomp/erl-xcomp-*.conf file. Unfortunately, I've hit an interesting 
issue and it appears the only other xcomp platform which would encounter it is 
VxWorks, which I do not have access to.

In my xcomp conf file, I use quoted values for CFLAGS and other environment 
variables. These get re-double-quoted by ts_install.erl as such:

Env: [{"CFLAGS",
       "\"-mcpu=cortex-a9 -Wno-psabi -fstack-protector-all -D_FORTIFY_SOURCE=2 
 -O2 -Wformat -Wformat-security -Werror=format-security\""},

As the VxWorks target also has quoted variables, how do the tests get compiled 
for that platform since the documented procedure in the "Testing the cross 
compiled system" section of the User's Guide *should* fail, per the results 
I'm seeing? Are tests not cross-compiled by anyone, ever, for that platform? 
Is there some undocumented magic I'm missing? Is this a legitimate bug I 
should fix while I trod down this obviously lightly-used path?

Thanks,

--Matt

P.S. As there doesn't seem to be any naming convention for configuration files 
in the xcomp directory and not much to work from, are there recommendations 
for the configuration file I'm working on? The host triplet is long, so would 
"something appropriate" be a good enough choice? I expect a > 40 character 
filename would be balked at. :)
