Undocumented build dependency: PCRE #8

almostimplemented · 2017-05-04T00:33:27Z

While building on OS X 10.12 I received the following build error:

The error indicates the PCRE library is absent (or unable to be found). My resolution was to install PCRE with my preferred package manager: brew install pcre. The solution will vary depending on OS, and in some cases PCRE may already be installed.

The text was updated successfully, but these errors were encountered:

Thanks for the report. I'm adding a note in the README.

Thanks -- and sorry: I hadn't seen #6 before raising the issue.

camerondavison · 2017-05-09T14:30:50Z

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?

niteria · 2017-05-09T15:23:01Z

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?

schultz-is · 2017-05-09T15:40:23Z

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?

schultz-is · 2017-05-09T16:15:15Z

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

camerondavison · 2017-05-09T19:33:56Z

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

niteria · 2017-05-09T20:37:31Z

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.

schultz-is · 2017-05-09T21:04:15Z

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

Summary: Turns out that `brew` can succeed installing `pcre`, but still not install development headers in `/usr/local/include/` if that path is not writable. `brew doctor` should find that and related problems.

camerondavison · 2017-05-10T03:04:32Z

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

mickume · 2017-08-09T10:45:46Z

The above worked for me as well, compiling is now OK after I installed gcc from brew.
