Description
At least the following image:
http://boxen.math.washington.edu/sage/osx/intel/sage-4.7-OSX-64bit-10.6-i386-Darwin.dmg
is defect. The build contains hardcode *absolute* paths the dynamic libs, e.g. something like libpng12.dynlib
is looked up at /Users/buildbot/build...
.
This makes it impossible to install spkgs which depend on libraries delivered by Sage. For instance, the spkg/patch from #11575 builds and installs, but is corrupted afterwards.

The counterpart of "chrpath" on OS X is called "install_name_tool", FWIW.

Alexander, just curious:
How does your $SAGE_ROOT/local/lib/pkgconfig/libpng12.pc
file look like (especially the first line)?

Replying to leif:
(Any definition of
SAGE_ROOT
inlocal/lib/pkgconfig/*.pc
can and should be removed.)
I'm meanwhile no longer sure about that, since (to me) it looks as if pkg-config
's behaviour has changed.
The following is definitely invalid and should be removed:
(I've seen this as a result of a build from scratch; reinstalling e.g. libpng12
cured this.)
SAGE_ROOT=${SAGE_ROOT}
The following are both ok (at least until the Sage installation moves, which sage
will notice upon start-up, then correcting / updating the path in the .pc
files):
prefix=/current/path/to/SAGE_ROOT/local ...
SAGE_ROOT=/current/path/to/SAGE_ROOT prefix=${SAGE_ROOT}/local ...
Unfortunately, the correction of the paths in .pc
files (as performed by sage-location
) isn't fully reliable at the moment, as the first example above shows.
Furthermore, sage-env
is broken in that it currently only sets (i.e., "overwrites") PKG_CONFIG_PATH
to $SAGE_ROOT/local/lib/pkgconfig/
if it is empty / undefined, instead of also prepending Sage's pkg-config
directory otherwise.
This means that PKG_CONFIG_PATH
should currently be unset (outside of the Sage environment) before installing or rebuilding any package.

As you know, this causes problems elsewhere as well. Is there a way to grep through this particular one and find all the places this is a problem?

Is this still an issue?

Obsolete by the new binary packaging.

Really, are you sure there no "buildbot" or "buildslave" things? I note that we still occasionally get such questions on ask.sagemath.

An ugly work-around is to create the original build directory (which ordinary users may not be able to), and make it a symbolic link to the new location (
$SAGE_ROOT
).In principle all shared libraries should have relative
RUNPATH
s. AFAIK currently most just use the library name (i.e., no [absolute] path), but rely onLD_LIBRARY_PATH
(DYLD_LIBRARY_PATH
on Darwin) instead.For ELF on UNIX / Linux etc., there is a tool
chrpath
(change run path) to (partially) fix such things in already built libraries and executables; I don't know if there's something similar available on Darwin.
