I ran brew config
and noticed that it said
Xcode: 8.3.2
CLT: N/A
So I installed CLT by running
xcode-select --install
Then I upgraded gcc from 5.3.0 to 7.1.0 using
brew upgrade gcc
and it I was then able to compile everything
from duckling.
Thanks for the report. I'm adding a note in the README.
from duckling.
Thanks -- and sorry: I hadn't seen #6 before raising the issue.
from duckling.
I am on mac 10.12.3
and ran brew install pcre
and have pcre-8.40
installed, but it does not seem to have worked for me. Anything else that needs to be installed?
from duckling.
Hmm, interesting.
What does brew info pcre
say?
What are the contents of /usr/local/Cellar/pcre/
?
What does gcc -lpcre
say?
Is the error message the same as above? If not, can you paste it?
from duckling.
i see the same issue. installing pcre
from homebrew does install the development headers, but maybe not in the location the compiler is looking for

@schultz-texas
What does gcc -lpcre
return?
How about gcc --version
?

That does look reasonable, are you compiling with stack
?
Can you paste the compile error you get?
from duckling.
figured it out. the default pcre
install doesn't seem to include development headers. submitted a pull request (#10) that includes updated documentation to pull source along with pcre
homebrew package
from duckling.
I did
brew uninstall --ignore-dependencies pcre
HOMEBREW_BUILD_FROM_SOURCE=1 brew install pcre
then ran
stack build
and get

well dang. i'll run back through my terminal history and see if there is some other intermediate step or path that caused it to work for me
from duckling.
Ok, I checked on my system and gcc
finds pcre.h
in /usr/local/include/
.
I've checked that it's brew
that installs it there.
I'd suggest running brew doctor
and fix the issues that it detects.
I expect it to find the issue described here: http://stackoverflow.com/questions/14527521/brew-doctor-says-warning-usr-local-include-isnt-writable
It may be that you'll have to reinstall pcre
after you make /usr/local/include
writable.
from duckling.
yeah, it's strange. seems to work fine on other machines for me. i can only imagine the reinstall of pcre
i did fixed the issue for me. went ahead and closed out the pull request i opened since it now seems unrelated
from duckling.
The above worked for me as well, compiling is now OK after I installed gcc from brew.
