osx - dylib set by rpath is not loaded in OS X -


i making package manager, , ensure packages use correct dependent library setting rpath option @ compile time. surprised me in os x (10.11), here problem:

$ otool -l /opt/starman/software/gcc/6.1.0/83894f21d07366be296600ec031ae4f6241381d9/libexec/gcc/x86_64-apple-darwin15.5.0/6.1.0/f951  /opt/starman/software/gcc/6.1.0/83894f21d07366be296600ec031ae4f6241381d9/libexec/gcc/x86_64-apple-darwin15.5.0/6.1.0/f951:     /usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)     /opt/starman/software/isl/0.17.1/104994def2b7fb2dae7950b42205eb718a46ee0c/lib/libisl.15.dylib (compatibility version 18.0.0, current version 18.1.0)     /opt/starman/software/mpc/1.0.3/6058925218009b8ab17e07333dc54de334134f6e/lib/libmpc.3.dylib (compatibility version 4.0.0, current version 4.0.0)     /opt/starman/software/mpfr/3.1.4/f142dfcda3b56650a8c9cfe2fdd09ffdf7283a00/lib/libmpfr.4.dylib (compatibility version 6.0.0, current version 6.4.0)     /opt/starman/software/gmp/6.1.0/0ec8ef118d09cb33f83559685d006f56a74f865c/lib/libgmp.10.dylib (compatibility version 14.0.0, current version 14.0.0)     /usr/lib/libsystem.b.dylib (compatibility version 1.0.0, current version 1226.10.1)

it says gmp in correct path not loaded since version 13.0.0, 14.0.0! know have older version gmp installed in path, after remove lib path dyld_library_path, problem gone, shouldn't rpath solve problem?

why dyld prints correct path of gmp, uses wrong old? there tricks in os x? help!

i don't understand why f951 binary load /opt/software/gmp/6.0.0a/0/lib/libgmp.10.dylib (version 13) rather /opt/starman/software/gmp/6.1.0/0ec8ef118d09cb33f83559685d006f56a74f865c/lib/libgmp.10.dylib (version 14) specified absolute path , not relative @rpath.

maybe it’s loaded indirectly via library, e.g. libisl.15.dylib, libmpc.3.dylib or libmpfr.4.dylib have @rpath reference libgmp.10.dylib?

to diagnose issue, suggest run main executable this:

$ dyld_print_rpaths=yes /opt/starman/software/gcc/6.1.0/83894f21d07366be296600ec031ae4f6241381d9/libexec/gcc/x86_64-apple-darwin15.5.0/6.1.0/f951

this print rpath expansions (both failure , success) , give answer question.

5 Reasons to Blog Anonymously (and 5 Reasons Not To)

Sure, some authors could pull it off, but if you worked at an office, what were you supposed to do? Go to work with a bag over your head?

Google AdWords and AdSense - A Dynamic Small Business Marketing Duo

Unless you have been living under a rock for the last year or so, you probably know that Google has become the king of the search engine hill. There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners. Here is an example - those ads in the box on the right of the page are delivered by Google and are matched to the content
