Hello,<br>
<br>
I am attempting to cross-compile OTP for a new platform, with a new<br>
$ERL_TOP/xcomp/erl-xcomp-*.conf file. Unfortunately, I've hit an interesting<br>
issue and it appears the only other xcomp platform which would encounter it is<br>
VxWorks, which I do not have access to.<br>
<br>
In my xcomp conf file, I use quoted values for CFLAGS and other environment<br>
variables. These get re-double-quoted by ts_install.erl as such:<br>
<br>
Env: [{"CFLAGS",<br>
"\"-mcpu=cortex-a9 -Wno-psabi -fstack-protector-all -D_FORTIFY_SOURCE=2<br>
-O2 -Wformat -Wformat-security -Werror=format-security\""},<br>
<br>
As the VxWorks target also has quoted variables, how do the tests get compiled<br>
for that platform since the documented procedure in the "Testing the cross<br>
compiled system" section of the User's Guide *should* fail, per the results<br>
I'm seeing? Are tests not cross-compiled by anyone, ever, for that platform?<br>
Is there some undocumented magic I'm missing? Is this a legitimate bug I<br>
should fix while I trod down this obviously lightly-used path?<br>
<br>
Thanks,<br>
<br>
--Matt<br>
<br>
P.S. As there doesn't seem to be any naming convention for configuration files<br>
in the xcomp directory and not much to work from, are there recommendations<br>
for the configuration file I'm working on? The host triplet is long, so would<br>
"something appropriate" be a good enough choice? I expect a > 40 character<br>
filename would be balked at. :)<br>
