[Mac OS X/Darwin] RPATH not defined in makefile.in

• Key: STDCXX-488
• Type: Bug
• Status: Resolved
• Resolution: Fixed
• Priority: Minor
• Assignee: Eric Lemings
• Reporter: Andrew Black
• Component/s: Build and Installation
• Affects Version/s: 4.2.0, 4.2.1
• Fix Version/s: 4.2.2

Description

When configuring a build on Mac OS X and Darwin, the generated makefile.in doesn't define a value for the RPATH makefile variable. As a result, the path to the library directory isn't embedded into the build. In turn, this leads to failures running the generated executables in dynamic builds.

A placeholder workaround is to define DYLD_LIBRARY_PATH.

The correct resolution is to determine the correct value for the RPATH variable.

This should be easy to fix. Scheduled for 4.2.1.

Assigned to Brad.

The patch is bad. See this discussion for the problems it has caused and some possible solutions.

[Martin Sebor]

Added 4.2.1 to the list of Affected Version/s and scheduled for 4.2.2.

See also this proposal for how to abstract away both the DYLD_LIBRARY_PATH and LD_LIBRARY_PATH variables from the makefiles.

Probably just need to remove the $BUILDDIR from the @install_name. Also, it might be possible to use the RPATH originally requested:

"And with 10.5 comes @rpath. If the install_name of your library is @rpath/libmysqlpp.2.dylib and you link your executable with, -Wl,-rpath,/home/graham/lib -Wl,-rpath,../lib -Wl,-rpath,. then the dynamic linker will look for libmysqlpp.2.dylib in each dir in turn until it finds it."

I tested the latest change (http://svn.apache.org/viewvc?view=rev&revision=662906) without setting BUILDDIR and without setting DYLD_LIBRARY_PATH and it seems to work as it should. Only tested on Darwin 9. Still needs testing on Darwin 8 but confident it is now resolved...for good.
