# Now we have a library specific to 'x86_64'. However what we use in lib.profiler
# is a so-called Universal Library (one library file which contains embedded libraries for
# multiple architectures .. this is an Apple speciality .. also known as a 'fat library').
#
# At some point in the history of NetBeans someone has created a Universal Library file
# for the Profiler Interface which as of Jan 2021 contains libraries for the following platforms: 
#    ppc 
#    ppc64 
#    i386 
#    x86_64
# Nowadays, Jan 2021, only 'x86_64' is relevant. Apple has abandonned the PowerPC architecture.
# Coming up is the Apple Sillicon architecture which is named 'arm64' in short form. No attempt
# is made here to support that, yet. 
#
# We re-use the existing Universal Library file and simply replace its contents but only
# for the 'x86_64' architecture. This means that libraries for other architectures will
# continue to exist in the bundle, albeit in the older form (meaning they'll not receive bug fixes)
#



# List architecture of the produced ".dylib" file  
# (just to be sure .. we expect it to be 'x86_64')

# List content of existing universal library
lipo "$UNILIB" -info

# Update the existing universal library so that the content for x86_64 is replaced
# with our recent build
lipo "$UNILIB" -replace x86_64 ../build/libprofilerinterface.x86_64.dylib -output "$UNILIB"
