Re: Mac qwt/qwtpolar build/install suggestions

[David F. <dfl...@ak...>]

When I deal with OSX, I have found that I can make #3 happen by 
appending the following to qwtconfig.pri

QMAKE_LFLAGS_SONAME  = -Wl,-install_name,/path/to/my/lib/

(And the final slash is required)

This way when you link other apps/libraries to the qwt dylib, they 
remember it's location without needing DYLD_LIBRARY_PATH.

AFAIK this is OSX specific and will have to be handled if you do more 
than one platform.

For diagnosing, you can use the OSX tool 'otool' which is roughly 
similar to readelf on Linux.
