How to Entice CMake or Extempore to find MacPorts glib?

[Neil Tiffin]

Everything with the new cmake build system seems to be working great, except for ‘make aot_extended’. The make system or extempore does not seem to honor

export LIBRARY_PATH=/opt/local/lib
export C_INCLUDE_PATH=/opt/local/include

in the terminal environment. As a result it fails to find glib.

Loading xtmstd library... done in 0.000000 seconds
sys:load notification std already loaded
Error: could not find libglib-2.0.dylib dynamic library

The lib is present as shown by:

MBP:~ nt$ find /opt -name libglib* -print
/opt/com.bitaxis/lib/libglib-2.0.0.dylib
/opt/com.bitaxis/lib/libglib-2.0.dylib
/opt/local/lib/libglib-2.0.0.dylib
/opt/local/lib/libglib-2.0.a
/opt/local/lib/libglib-2.0.dylib

make itself did not seem to have a direct option for finding libs, but I am not sure if the problem is make or extempore?

In the environment we have

MBP:cmake-build nt$ env
. . . .
LIBRARY_PATH=/opt/local/lib
PATH=/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/opt/X11/bin:/Library/TeX/texbin
C_INCLUDE_PATH=/opt/local/include
PWD=/Maui-Dev/extempore/extempore/cmake-build
. . . .

Any ideas?

Thanks,

Neil

Hi Neil

So will bind-dylib find glib* if you're not aot-compiling? i.e. if you
blow away the AOT cache (make clean_aot) and try loading
libs/external/glib.xtm, does that work?

One possibility is to try DYLD_LIBRARY_PATH instead of LIBRARY_PATH

Cheers,
Ben

Ben,

Thanks, LD_LIBRARY_PATH=/opt/local/lib seems to be working. DYLD_LIBRARY_PATH did not.

Thanks,

Neil

Hi Neil

Cool, great. Are you on OSX, or linux? My understanding was that it's
the LD_* version for Linux, and the DYLD_* version on OSX (at least,
according to man dyld on my OSX 10.11 box). But I could easily be wrong
- it happens pretty frequently, just ask Andy :)

Well there you go. Thanks for the heads up.
