nocamlp4

[samoht]

any plan to remove the camlp4 dependency? There's a new version of sexplib which just uses ppx.

I believe so, x509 is already being ported over: https://github.com/mirleft/ocaml-x509/pull/75

It's in master, rel pending.

I still wish we had a solution for for findlib warning that is DDOSing the build:

findlib: [WARNING] Interface topdirs.cmi occurs in several directories: /usr/lib/ocaml/compiler-libs, /usr/lib/ocaml
+ /home/self/.opam/system/bin/ocamlfind ocamlc -c -g -annot -bin-annot -ccopt '--std=c99' -ccopt -Wall -ccopt -Wextra -ccopt -Werror -ccopt -O3 -ccopt -DACCELERATE -ccopt -msse2 -ccopt -maes -w A-4-29-33-40-41-42-43-34-44 -package zarith -package sexplib -package ppx_sexp_conv -package cstruct -I src -o src/nocrypto.cmi src/nocrypto.mli

make 2>&1 | grep -v '[WARNING] Interface topdirs :D

Out of curiousity, what is the real cause for the warnings? I'd also like to fix them.

I think @samoht was looking into this, it seems the toplevel directives (topdirs) are apparently part of the compiler and the compiler libs and the file is duplicated.

@pqwy: Thanks for merding; I agree, this should get fixed soon to avoid this useless noise.

I still wish we had a solution for for findlib warning that is DDOSing the build:

There is an environment variable responsible for this: OCAMLFIND_IGNORE_DUPS_IN. If you set it

     export OCAMLFIND_IGNORE_DUPS_IN=`opam config var lib`/compiler-libs

The boring messages will disappear.

You can also put this into your build system. For example, if you're using oasis, then setup.ml is a good place to put Unix.putenv.

One of the ppx libraries is using compiler-libs library (if I recall it correctly it is ppx-driver). It just happens, that this library duplicates topdir module. I suspect that it is already fixed in the trunk.

and thank you for the merge!
