Cannot include ex_uri.hrl

[marccampbell]

From a fresh clone of the hithub repo, I get:

src/socketio_listener.erl:4: can't find include lib "ex_uri.hrl"

when running rebar compile.

This seems to work for me:

What build steps do you use?

[omarkj]

I get this as well now, am looking at it.

My steps are:

git clone https://github.com/yrashk/socket.io-erlang.git
cd socket.io-erlang
make

[ferd]

I would bet on an outdated rebar version. The Makefile uses './rebar compile' while my own code snippet above uses 'rebar compile', aka the global rebar I have installed.

[omarkj]

That was my idea as well, I'm using:
rebar version: 2 date: 20110916_115720 vcs: git fa1bbc6

Oddly enough, if I run

rebar get-deps
rebar compile <-This fails
rebar compile <- Second one is successful

Any idea what that can be?

[ferd]

The true build problems were caused by the merge #63, which added
a fix to the -include_lib path to better work with release.
However, this introduced a problem when compiling with rebar
given rebar calls 'erlc', which ignores all ERL_LIBS options
and thus will only support the default system libs (apparently).

I fixed this by adding a macro definition to rebar.config and a
preprocessor switch to the socketio_listener module (which had
the include_lib changed) so that when compiled from rebar, we
use the old code that worked, and when going without rebar, we
use the fix that existed.

Hopefully this won't break the fixes brought by merge #63

Let me know if this fixed the issue

[sbalea]

My initial fix failed because it was missing a rebar.conf tweak (needed to include "deps/". My bad, forgot to include it in the pull request.
Unfortunately ferd's fix to my fix did break the scenario where socketio is a dependency or a larger, rebar-based application. Rebar is funny sometimes: it dumps all deps and sub-deps into a flat deps/ directory, while at the same time it descends into deps directories and applies rebar.config setting as if they would be top level. Bottom line is what works in standalone mode, might not work in dependency mode.
In any case, I'm prepping a new pull request that hopefully fixes things for everybody. Stay tuned.

I had the same problem, didn't work with rebar get-deps + rebar compile but instead only running make worked.
