Hello everyone :)
I have a problem that I cannot fix when compiling a C++ source block.
My code block use several libraries and especially one named
libarmadillo.dylib which is installed in a non-default place.
My code compiles well in the buffer shell of emacs with :
g++ -I/Users/benoitbayol/libs/include
/Users/benoitbayol/libs/lib/libboost_system.a
/Users/benoitbayol/libs/lib/libboost_chrono.a
/Users/benoitbayol/libs/lib/libboost_thread.a
-L/Users/benoitbayol/libs/lib -larmadillo main.cpp
but if I copy paste these flags and put them in :
#+begin_src C++ flags : -I/Users/benoitbayol/libs/include
/Users/benoitbayol/libs/lib/libboost_system.a
/Users/benoitbayol/libs/lib/libboost_chrono.a
/Users/benoitbayol/libs/lib/libboost_thread.a
-L/Users/benoitbayol/libs/lib -larmadillo
The compilation process with babel complains about a dylib
(libarmadillo.3.dylib) which cannot be found with :
dyld: Library not loaded: libarmadillo.3.dylib
Referenced from:
/var/folders/xh/vvf5bjg15c3_rn5kdb4d2lk40000gn/T/babel-329218a6/C-bin-32921x5m
Reason: image not found
In the /Users/benoitbayol/libs/lib folder I have
-rwxr-xr-x 1 benoitbayol staff 41592 28 jan 14:03
libarmadillo.3.92.2.dylib
lrwxr-xr-x 1 benoitbayol staff 25 28 jan 14:03
libarmadillo.3.dylib -> libarmadillo.3.92.2.dylib
lrwxr-xr-x 1 benoitbayol staff 20 28 jan 14:03
libarmadillo.dylib -> libarmadillo.3.dylib
I tried to fix my .emacs with (setq org-babel-C++-compiler "g++
-L/Users/benoitbayol/libs/lib") but I doesn't work.
Does anybody have an idea ?
Thanks :)

Maybe it is just a miss-placed colon.
Try
#+begin_src C++ :flags -I/Users/benoitbayol/libs/include etc...
instead of
#+begin_src C++ flags : -I/Users/benoitbayol/libs/include etc...
