14 years ago Hi,
There are two possible explanations IMO.
1) Homebrew only installed the IL library and not the ILU library 2) You initially already had IL installed (but not ILU) and the Homebrew installation of IL and ILU are not being detected during compilation.
If the answer is 1. (which you can verify by searching the library locations for a libILU.bundle and not finding it) then the homebrew DevIL package needs to be updated to include the ILU library (and also, perhaps, the ILUT libraries), and IMO you should contact the maintainers.
If the answer is 2. on the other hand, you need to pass the homebrew library folder along to gcc upon compilation. You do this by editing the LDFLAGS in extconf.rb. You can also tell me what path you used, and i can add it to exconf.rb so to support homebrew in the future :)
Let me know how you get on :)
Hi, I'm used brew to install the devil libraries and I'm unable to install the devil gem. Looks like it can't find -lILU, any ideas?
