Bug 136158 – [GTK] WebKit has a new required dependency on GnuTLS

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Martin Robinson]

We should not be adding required dependencies, so WebCrypto should be disabled when GnuTLS is not found:

--  WTF_USE_TILED_BACKING_STORE               OFF
--  ENABLE_PLUGIN_PROCESS_GTK2 .............. ON
-- checking for module 'libsecret-1'
--   package 'libsecret-1' not found
-- Could NOT find LIBSECRET (missing:  LIBSECRET_INCLUDE_DIRS LIBSECRET_LIBRARIES)
CMake Error at /home/guijemont/.local/share/cmake-3.0/Modules/FindPackageHandleStandardArgs.cmake:136 (message):
  Could NOT find GnuTLS: Found unsuitable version "2.12.14", but required is
  at least "3.0.0" (found /usr/lib/x86_64-linux-gnu/libgnutls.so)

cmake only complains if you explicitly enable SUBTLE_CRYPTO and it fails to find the required dependencies. I understand that's the correct behavior.

It is build-webkit that sets ENABLE_SUBTLE_CRYPTO by default, if you call cmake directly instead it works fine.

So maybe we should disable subtle-crypto by default in build-webkit?

The patch looks good to me, r+ anyone?

[Martin Robinson]

If this if provided by the JHBuild, I don't think it's necessary. If it's not provided by the JHBuild, perhaps it should be?

Actually Tools/gtk/install-dependencies is already installing
libgnutls-dev, so maybe there's nothing to fix here?

WebCrypto is already disabled when we use cmake directly, so I don't
think distributors/end users are really required to install gnutls.

Probably it should be one of those features that's enabled only when the dependency is found. I think Safari is shipping it so we can probably start as well.
