Io: Addon libraries in $prefix/lib/io/addons link against non-existant paths

[markemer (Mark Anderson)]

When trying to install Io on 10.7, I get the following:

--->  Scanning binaries for linking errors: 95%
Warning: Error parsing file /opt/local/lib/io/addons/LZO/CMakeFiles/IoLZO.dir/source/minilzo.c.o: Premature end of data, possibly corrupt file

It then rebuilds 3 times before giving up.

[neverpanic (Clemens Lang)]

for file in $(find $prefix/lib/io/addons -iname '*.dylib'); do otool -L $file | grep "$prefix/lib/libIo"; done | sort | uniq shows some libraries in lib/io/addons link against files that do not exist. Those files can be found in $prefix/lib/io/addons/$extension_name/_build/dll/libIo$extension_name.dylib.

The maintainer should consider fixing the broken linkage paths by adjusting the build process or after the build with install_name_tool -change. If a non-issue or not-fixable we can also have problems in these files ignored by rev-upgrade, however this should be the last resort in such cases.

Is there currently a way to fix this without uninstalling Io?

I have successfully gotten Io to build using the Portfile diff I just attached (though I had to build with gcc; building with clang seems to cause some kind of infinite loop in io_static during the build).

[ryandesign (Ryan Carsten Schmidt)]

Thanks. Since this changes the files that get installed, the revision must also be increased.

Using a variable called "name" is confusing because portfiles already have a variable called "name" (the port name).

I've committed a modified version of your patch in r101673 which results in only one invocation of install_name_tool per library. I nested the loops, so I had to rename the other variables to not collide.

Thanks! This is great.
