Opam build fails on Ubuntu 16.04 using Ocaml 4.04.2

[tomsib2001]

Hi,
When I try to install omake 0.10.3 using opam, i get the following error:

# opam-version 1.2.2
# os           linux
# command      make
# path         /home/thomas/.opam/tezos_fresh/build/omake.0.10.3
# compiler     4.04.2
# exit-code    1
# env-file     /home/thomas/.opam/tezos_fresh/build/omake.0.10.3/omake-6858-5f1023.env
# stdout-file  /home/thomas/.opam/tezos_fresh/build/omake.0.10.3/omake-6858-5f1023.out
# stderr-file  /home/thomas/.opam/tezos_fresh/build/omake.0.10.3/omake-6858-5f1023.err
### stderr ###
# *** Error in directory /home/thomas/.opam/tezos_fresh/build/omake.0.10.3: No way to execute phony target: default

The error can be replicated by simply doing make.

Hi,
I cannot reproduce this. Tried this by installing the official Ubuntu 16.04 Docker image, followed by apt-get install build-essential m4 opam, then initialized opam (opam init, opam switch 4.04.2), then installed omake.

Any special environment variables (omake as a build tool is somewhat sensitive to this)? What is ocamlc -config?

Hi,
Here is the output I get for ocamlc -config:

My fix for the bug was to clone the repository, pin the directory and modify the build line in the opam file by changing make to make all.

[gerdstolpmann]

Still, there is something different on your system. Which make utility do you use? I could not find the string "no way to execute" in the source of GNU make, so it must be something else.

[tomsib2001]

make -v returns

GNU Make 4.1
Built for x86_64-pc-linux-gnu

Otherwise, my system is pretty much brand new.

EDIT: I found the string "No way to execute phony target" in https://github.com/ocaml-omake/omake/blob/master/make.ml so apparently, make is trying to use omake already.
