after pull it doesn't compile

==> proper (compile)
include/proper_internal.hrl:26: can't find include file "compile_flags.hrl"

I am afraid I cannot reproduce what you are reporting. Is it possible that you need to do a 'make distclean' first? Do you have a compile_flags.hrl file in the include dir? (This file could actually be empty, depending on the OTP version you are using.)

I'm sorry, but bug still in there. It can't be reproduced when compiled as a standalone application. Instead, try to compile it as 'dependency' application usin 'rebar' tool:

==> vsports (get-deps)
[...]
Pulling proper from {git,"https://github.com/manopapad/proper.git","master"}
Cloning into 'proper'...
[...]
==> proper (compile)
src/strip_types.erl:50: Warning: missing specification for function parse_transform/2
Compiled src/strip_types.erl
include/proper_internal.hrl:26: can't find include file "compile_flags.hrl"
make: *** [all] Error 1

The file compile_flags.hrl didn't created, find (1) didn't found it. I think this is because you try to execute 'write_compile_flags' script in current directory, when, in fact, the current directory is for upper level application and proper located in 'deps/proper' directory.

I see. However, I am not convinced that this is a problem in PropEr instead of your rebar use or your directory structure.
For example, due to issues 23, 25 and 26 , I know for a fact that there are various projects that use PropEr as a dependency and do not have the problem that you reported (this is because they found other problems, which by now are solved). You may want to look at the code bases of the developers that reported the issues and get some inspiration on how to add PropEr as a dependency in your code base.

In any case, if you do not manage to fix the problem in the way I suggested, we'll gladly consider to include in PropEr's code base a pull request that fixes the problem.

Is this issue fixed by now or you still have problems? If you have managed to solve it somehow we would be interested in finding out how this was done and possibly incorporate your fix into PropEr.

Since a month has passed and there have been no replies from the person staring this thread, I am closing it. Open a new issue if there are still problems.

For those who end up here after google search of this error. It's caused by having too old version of rebar installed. Just upgrade rebar and you will be fine.

I had the same issue and your note helped solving it. Thank you @JonGretar.
