Ivan Zhakov reopened SERF-151:
------------------------------
Re-open to update Fix version.
> SCons: env['LIBPATH'] sometimes is a string and that breaks RPATH
> -----------------------------------------------------------------
>
> Key: SERF-151
> URL: https://issues.apache.org/jira/browse/SERF-151
> Project: serf
> Issue Type: Bug
> Reporter: Serf Importer
> Priority: Major
> Labels: Priority-Medium, Type-Defect
>
> Per 'man scons':
> env.Append(key=val, [...])
> [...] If the values
> of the construction variable and the keyword argument are the same
> type,
> then the two values will be simply added together. Otherwise, the
> construction variable and the value of the keyword argument are
> both coerced
> to lists, and the lists are added together. (See also the Prepend
> method,
> below.)
> The result is that under some circumstances (GSSAPI disabled, and possibly
> more), LIBPATH is only modified by this single call before getting to setting
> RPATH:
> env.Append(LIBPATH='$OPENSSL/lib')
> As a result, env['LIBPATH'] is a string and the following:
> for d in env['LIBPATH']:
> env.Append(RPATH=':'+d)
> iterates over characters of that string rather than list elements. As a
> result, RPATH ends up like '$:O:P:E:'... and that isn't really useful.
> I'm attaching a patch that fixes the issue through consistently appending
> lists to variables, except for RPATH. This way, SCons guarantees that the end
> result will be a list and everything will work fine.
