CPPFLAGS=-I/Applications/VLC.app/Contents/MacOS/include LDFLAGS=-L/Applications/VLC.app/Contents/MacOS/lib/ ./configure --with-pd=/Applications/Pd-extended.app/Contents/Resources/include/pd/ --enable-fat-binary=x86_64 --with-ftgl-includes=/sw/include/ --with-libvlc-includes=-I/Applications/VLC.app/Contents/MacOS/include --with-libvlc-libs=-L/Applications/VLC.app/Contents/MacOS/lib because when I do so I get the same @loader_path/lib/libvlc.5.dylib m On Wed, Apr 4, 2012 at 9:58 AM, Hans-Christoph Steiner <h...@at.or.at> wrote: > > @loader_path is where the plugin was loaded from, so in your case: > /Users/megrimm/Library/Pd/Gem/plugins/videoVLC/.libs/ > > That means its looking for libvlc here: > /Users/megrimm/Library/Pd/Gem/plugins/videoVLC/.libs/lib/libvlc.5.dylib > > On Mac OS X, the thing to do is to link against the libvlc included in the > VLC app.Then anyone who wants to use the VLC plugin for Gem just installs the > normal VLC app. You can find that here: > /Applications/VLC.app/Contents/MacOS/lib/ > > That would mean adding -I/Applications/VLC.app/Contents/MacOS/include to > CPPFLAGS and -L/Applications/VLC.app/Contents/MacOS/lib/ to LDFLAGS for the > build.
