lablgl's Issues
"ld: library not found for -llablgl" when I dune build
I originally asked over here sanette/oplot#5
but I guess the real issue is something wrong with my lablgl install
I am trying to use oplot, which has lablgl as a dependency.
oplot works fine in ocaml shell (with #use "topfind" if that is relevant), suggesting that lablgl is installed ok.
But when I add (libraries oplot) to the dune file of my project, when I dune build I get:
ld: library not found for -llablgl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
File "_none_", line 1:
Error: Error while building custom runtime system
I have:
$ opam list | grep gl
lablgl 1.06 Interface to OpenGL
Any ideas how I could get this working?
(I am guessing I may need to add something to my LD_LIBRARY_PATH but I'm not sure what)
