Subject [jira] [Commented] (COUCHDB-1426) error while building with 2 spidermonkey installed
Date Thu, 01 Mar 2012 21:38:01 GMT

Paul Joseph Davis commented on COUCHDB-1426:
--------------------------------------------

@benoit

How about we match the rest of the file for formatting? There are zero cases of indentation
matching the argument column. Fixed width indents are used throughout and should be used here
as well.

As to the actual test in that AC_COMPILE_IFELSE I finally realized that its relying on an
error being generated due to an invalid preprocessing instruction. It would be better to use
the error preprocessor directive there.

The more I think on this the less I think its fixing either issue directly. The globally installed
SM 1.8.5 should have put its headers into $PREFIX/js/ which was being picked up by the three
lines you removed that I explicitly added in response to a different error report. Seeing
as the header checks haven't changed I'm still not convinced that this isn't introducing a
regression for some combination of headers installed.

On the other hand, there's also this large rearrangement to fix the detection of SM170 which
didn't have the anonymous function option. It sure does seem like there's quite a bit of change
for this.

IOW, this patch should be at least two patches. And I'm not convinced we should even attempt
at supporting building against multiple installed versions of a library. Picking up headers
from system directories is going to be a bitch regardless and trying to teach configure.ac
to do a dance itself into knots figuring this out seems like a losing proposition.

> Context:
> To bench the differences between different versions of couchdb I had to test against
spidermonkey 1.7 and 1.8.5 . 1.8.5 is installed globally in /usr/local  while the 1.7 version
is installed on a temporary path. 
> Problem:
> Using --witth-js-include & --with-js-lib configure options aren't enough to use the
1.7 version it still want to use spidermonkey 1.8.5 . Removing js-config from the path doesn't
change anything.  I had to uninstall spidermonkey 1.8.5 to have these setting working.
