HEAD (2.5) build failure on OSX 10.8/Clang and fix
« on: June 05, 2013, 06:20:15 pm »
Building complains about two function calls in src/shared/images.cpp on account of no matching functions in jpeglib.h and no known conversion from bool to boolean; the offending argument is "true", and nearby similar functions use "TRUE" in the same position. Changing the two offending calls to "TRUE" satisfies the compiler; it looks like this might have been a typo (or brain-o) that might be concealed by an implicit conversion in other build environments. The relevant patch is included below:

You missed the second occurrence (not hard, the code block hides it and gives no indication there's anything to scroll to).
