terminating with uncaught exception of type syntax_error: Invalid operator: - about cparse

[VinGarcia]

Hello @chrisabrams,

I made a small test here and I think I know what is going on, tell me if I am wrong:

I first ran the make release recipe, it compiled fine but shown some warnings (I have to look into them, they're probably from the last PR)

Then I compiled your file (I saved it as main.cpp) twice, the first one including the builtin-features the second one ignoring it here are the results:

vingarcia@vingarcia-dito:~/projects/cparse$ g++ -Wall -pedantic core-shunting-yard.o builtin-features.o main.cpp 
vingarcia@vingarcia-dito:~/projects/cparse$ ./a.out 
-2.14
vingarcia@vingarcia-dito:~/projects/cparse$ g++ -Wall -pedantic core-shunting-yard.o main.cpp 
vingarcia@vingarcia-dito:~/projects/cparse$ ./a.out 
terminate called after throwing an instance of 'syntax_error'
  what():  Invalid operator: -
Aborted (core dumped)

Is this what you are seeing?

If it is, the problem is just that you are missing the builtin features, I made them like that because someone might not like the default operators and want to create something from 0.

Yes that is the error I got! Ok, I will try to figure out how to add builtin-features.o to Xcode.

Figured out Xcode, I will try to make a PR to add OS X/Xcode to the instructions.
