Having trouble building on macOS High Sierra (10.13.3)

[malchata]

When I attempt to compile using make -j8 in macOS High Sierra, I receive the following error:

image_io.cc:1031:31: error: assigning to 'boolean' from incompatible type 'bool'
  cinfo.do_fancy_upsampling = true;
                              ^~~~

Full compiler output: compiler_output.log

Is there anything I'm doing wrong, or is this a legitimate error? Here's my system info (using a Kaby Lake Intel, currently):

Hardware Overview:
Model Identifier: MacBookPro14,2
Processor Name: Intel Core i5
Processor Speed: 3.1 GHz

Thanks for reporting this. Looks like the High Sierra compiler is more strict.
Can you confirm that c++ --version reports LLVM 7.3.0?
We'll update the code to avoid the type mismatch.
In the mean time, you can try defining HAVE_BOOLEAN=1 and boolean=bool before #include "jpeglib.h".

Should be fixed by 200c784, please re-open if not :)

It works! Thank you so much @jan-wassenberg! You rule!
