opam install ssl (0.5.5) error

[bit-fu]

opam install ssl (0.5.5) returns an error on Darwin (macOS) that didn't happen with 0.5.4:

... CPPFLAGS=-I/usr/local/opt/openssl/include LDFLAGS=-L/usr/local/opt/openssl/lib
# configure: error: Cannot find libssl headers.

There is no “/usr/local/opt” in Darwin.

The same error occurs when I create “/usr/local/opt/openssl” and put symbolic links to existing openssl directories there.

Could it be that the “opam” file (new in 0.5.5) is faulty? The “opam” in the conf-openssl package looks different.

Ok, I see where this is coming from. Do you also have an error installing conf-openssl? You might need to opam reinstall conf-openssl. Thanks.

[bit-fu]

Nope, same error. `opam reinstall conf-openssl` didn’t change anything, the “opam” file there is exactly the same as before. I unpinned from ssl-0.5.4 and did `opam upgrade` to get 0.5.5 and have the same error. Please compare the openssl configs in the “opam” files in the ssl (0.5.5) and conf-openssl packages. They are different. My hunch is that the error lies there, but in the ssl package, not in conf-openssl. ssl-0.5.4 installs flawlessly with the exact same conf-openssl, but then, it doesn’t have its own “opam”.

My question was wether conf-openssl also installed with or without errors. The opam file there also reffers to /usr/local/opt:

build: [
  ["pkg-config" "openssl"] {os != "darwin" & os != "freebsd" & os != "openbsd" & os != "netbsd"}
  ["sh" "-exec" "PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig pkg-config openssl"] {os = "darwin"}
]

I wrote a detailed explanation of the situation in ocaml/opam-repository#10453

Let's start by the beginning then:

• Which version of macOS are you using?
• Did you install openssl through homebrew?
• What do you get when you execute: brew info openssl

Thanks!

[bit-fu]

Yes, conf-openssl has always installed without error. The macOS version (10.12.6) seems to be irrelevant, since I can install ssl-0.5.4 right now without error by version-pinning it, on my same OS, with the same conf-openssl. openssl is (and always was) installed via MacPorts, and it seems to lack a pkg-config (doing `pkg-config openssl` outputs nothing). The one conspicuous difference between ssl-0.5.4 and ssl-0.5.5 is that the latter has an “opam” file where the former didn’t. And the openssl config there differs from conf-openssl. So I thought that might be a viable lead, since the build fails in the “configure” stage.

The local opam file in ocaml-ssl is not being used. Your issues comes from the fact that openssl support in opam-packaged ssl is based on the homebrew version of openssl.

Previous versions were compiling/installing because of a bug in ocaml-ssl where it did not honor the given LDFLAGS config, resulting in improper linking against the wrong library.

pkg-config ssl is supposed to return nothing. It exits with error code 1 when ssl cannot be found. Here:

% pkg-config openssl
zsh: exit 1     pkg-config openssl
% PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig pkg-config openssl
(nothing)

I would like to properly address this but I'm gonna need a couple of input from you:

• Are you sure that you are actually reinstalling the latest conf-openssl? This package was changed as recently as yesterday I think and I would hate to miss an issue there while fixing your issue. Try:

opam update
opam reinstall --verbose conf-openssl

Latest version should log:

[conf-openssl: sh] Command started
+ sh "-exec" "PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig pkg-config openssl" (CWD=/Volumes/Home/toots/.opam/4.04.0+32bit/build/conf-openssl.1)
- + PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig
- + pkg-config openssl
∗  installed conf-openssl.1

• Do you know the content of the MacPorts openssl package? Where does it ship openssl headers and shared objects?

Thanks!

[bit-fu]

I have conf-openssl.1 installed, but I did the `upgrade` & `reinstall --verbose` nevertheless just to be sure. It says what you show in your mail and the error persists. MacPort’s openssl paths are, headers: /opt/local/include/openssl shared objects: /opt/local/lib (it has “libssl.1.0.0.dylib” and “libssl.a”) I looked and there is actually an “openssl.pc” in “/opt/local/lib/pkgconfig”, and the exit code of `pkg-config openssl` is 0 on my system, while outputting nothing.

Excellent, thanks. I'll fix this ASAP.

[toots]

Ok, I have pushed a fix. Could you try the following:

git clone --recursive https://github.com/savonet/ocaml-ssl.git
cd ocaml-ssl
opam pin add ssl .

You will need autoconf and automake. Looks like macport has ports for each of those.

If you can confirm with me that this works, I'll push the updates to the main opam repository.

[bit-fu]

I had to tweak it a bit, but your fix is working. In the freshly cloned “ocaml-ssl” dir, I did the following (“$” is the shell prompt): $ ./bootstrap $ ./configure --includedir='/opt/local/include' --libdir='/opt/local/lib' CPPFLAGS='-I/opt/local/include' LDFLAGS='-L/opt/local/lib’ $ make # success! # For the `opam pin` to succeed, I had to edit “./opam/files/osx-configure.sh” a bit. The “-I” option in the CPPFLAGS variable must be “/opt/local/include” for the MacPorts branch, since C code inserts the “openssl” subdirectory in its `include` directive. So, the same “-I” as for `configure` in “osx-configure.sh”. Thank you very much :)
