simple linking to .dylib: how?

davecotter

in my .pro file i have this:

DIR_BOOST		= $${DIR_EXTERNAL}boost_1_68_0/
DIR_BOOST_LIBS		= $${DIR_BOOST}stage/lib/
DYLD_LIBRARY_PATH	+= $${DIR_BOOST_LIBS}

LIB_BOOST_THREAD	= libboost_thread
LIBS += -l$${LIB_BOOST_THREAD}

yet at compile time i get this:

ld: library not found for -llibboost_thread

i started with:

LIBS += -L$${DIR_BOOST_LIBS} -l$${LIB_BOOST_THREAD}

but that also fails.

i have confirmed that the path is definitely correct, and the file "libboost_thread.dylib" definitely exists there and is compiled correctly

the linker is sent this command:

-L../../../External/boost_1_68_0/stage/lib/ -llibboost_thread

is it that the path must be absolute (not relative) ?

what am I missing?

oh! huh. that's not the name used in the file system, which is why i was (am?) confused. thanks, that worked!

Hi,

It's -lboost_thread like on Linux.

On *nix systems, you drop the lib prefix when linking to a library. Like for example libz -> it's -lz.
