Fatal error: exception Failure("php checker needs a graph file") - Mac Sierra

[ScottAtGithub]

I downloaded the latest version from github today, but I always got the following error message when I tried scheck on a few php files on my Mac. This is what I tried:

./scheck ./tests/php/coverage/t1_a.php
Fatal error: exception Failure("php checker needs a graph file")

Please help. Thx!

I was just able to run it. You need to build graph data first. For some reason scheck requires working directory to be the source code of the target. This should work:

mkdir ~/pfff_output
cd ~/phpsource
~/pfff/codegraph -lang php -derived_data -o ~/pfff_output/ -build ~/phpsource
~/pfff/scheck -lang php -with_graph_code ~/pfff_output/graph_code.marshall ~/phpsource

I was able to build pfff yesterday but codegraph was not there, so I downloaded and installed softwares/plugins like gtk but was failed in building pfff (ml_glib.c:165:3: error: use of undeclared identifier 'caml__frame').

Let me try to see if I can fix it. Thank you very much anyway!

that's interesting, I used install_macos.txt guide

I am also having issues compiling on OS X Sierra.

ml_glib.c:165:3: error: use of undeclared identifier 'caml__frame'

Same for me, but on OS X El Capitan.

I followed the build instructions in install_macos.txt, make then dies with

ml_glib.c:165:3: error: use of undeclared identifier 'caml__frame'

Edit: This should probably be reported as a separate issue I suppose?

@maxbeutel I encountered the same error in macOS Sierra.

[istana]

me too, but I'm not sure how to fix it

[petitchevalroux]

It's seems to be related to ocaml 4.04. The same issue (facebook/hhvm#7560) exists in hhvm.

Workarounds :

1. Downgrade ocaml 3.15.3 Source version fails to build on OSX 10.12.2 facebook/hhvm#7560 (comment)
2. Use this commit (at your own risks xD) petitchevalroux@10a3991 based from
