.pc file is not generated

Issue #572 new
Janani T E created an issue

Reported by "slhck" (Werner Robitza) on "2020-09-10T12:24:51.179514+00:00"

Using the latest master branch and Release\_3.4, x265 does not create a .pc file to be used with pkg\_config.

Tested under Ubuntu 20.04.

Installed dependencies:

```
apt-get update -qq && apt-get install -qq -y \
  autoconf \
  automake \
  build-essential \
  cmake \
  libfreetype6-dev \
  libtool \
  pkg-config \
  texinfo \
  wget \
  yasm \
  nasm \
  zlib1g-dev \
  libnuma-dev \
  git
```

Following the guide from the FFmpeg wiki, which usually works fine, I get this output:

```

So it’s looking for the x265.pc file which is not generated.

Anything that changed, or any options that should be modified?

    @Werner Robitza Please follow up with this new issue for the ticket which you created earlier.

  2. Werner Robitza

    Huh, where is the old issue gone? I see a lot of broken links around here unfortunately.

    ‌

  3. Janani T E reporter

    I hope you are aware that we migrated all our Hg repos to Git in Bitbucket. Since we had restored the HG issues yesterday, it had overwritten all the Git issues. We have created the Git issues with the respective person who had reported it and notified them the same. Hope this clarifies.

  4. Werner Robitza

    I noticed the switch to another repository, yes, I was just confused about the issues. Thanks for clarifying that they were migrated!

  5. Francisco Boni

    The fix seems simple. ${GIT_EXECUTABLE} describe --abbrev=0 --tags in version.cmake fails because there is no tag associated with the current master branch. The implication is that the .pc file generation fails without the output variable X265_LATEST_TAG being properly defined.

  6. Francisco Boni

    Correction: When you do “git clone --depth=1”, a shallow clone of the repo, the tags are not fetched by design. Do git fetch --tags to get the tags. Now the current master branch will build and install .pc files.

  7. Werner Robitza

    Thanks for investigating this. It does not seem like a real solution to me though, particularly for end users. As there is no apparent error message, it is not obvious to someone installing the library what happened. Also, users may have good reasons to want shallow clones, for example, in order to save network bandwidth.

    The way in which the software is obtained ultimately should not impact the ability to build it correctly.

    Let me suggest a different fix. If it is a requirement for building to know the latest tag, a file containing it could be part of the repository and updated on release. This would make the source code self contained.

    ‌

  8. Francisco Boni

    I agree with your idea. Building from the lastest master should be compatible with a shallow clone, as the complete clone is over 300MB.
