Make fails On ubuntu 14.04:ocamlfind: Package `bytes' not found

[zfalcon]

make[1]: Entering directory /tmp/buildd/liblwt-ocaml-2.4.8' debian/build.sh ocamlfind: Packagebytes' not found W: Field 'pkg_bytes' is not set: Command ''/usr/bin/ocamlfind' query -format %d bytes > '/tmp/oasis-40795f.txt'' terminated with error code 2 E: Cannot find findlib package bytes E: Failure("1 configuration error")

But When I tar this package and enter the folder(_build/SRPMS/lwt-2.4.8#) , use command list: ./configure --disable-libev make

it‘s Successful!

This will be because we are using ocamlfind from Ubuntu which is older than required. We need to back port a newer version. I don't recall exactly which ocamlfind version introduced the 'bytes', but it's certainly in 1.5.5, which is why the opam build succeeded.

Thank you for your reply!

Thank you very much!!
