Unnecessarily shipped libtool archive (.la) files are invalid

[Benjamin Drung]

The libtool archive files /usr/lib/libvamp-hostsdk.la and /usr/lib/libvamp-sdk.la are invalid and break building packages with libtool. This causes the svn version of Audacity fail to build. There is no way to work around the broken .la files when using libtool.

The simple solution is to remove the .la files from the package. Then libtool with use the .so or .a files.

[Test Case]

echo "main() { return 0; }" > main.c
libtool --mode=link g++ main.c -o main $(pkg-config vamp-hostsdk --libs)

The libtool command should succeed instead of failing with:
libtool: link: `/usr/lib//libvamp-hostsdk.la' is not a valid libtool archive

[Regression Potential]

The risk for regressions is low. Only libtool uses the .la files. Linking against the libraries without using libtool will not be influenced by the existance or not existance of .la files.

As you can see in the recipe for precise and quantal [1], Audacity builds again with -proposed enabled. Therefore I verify that the fix works.
