Headers appear to be missing in glslang-dev 14.0.0

[Douglas Friedel]

I recently updated my Ubuntu from 22.04 to 24.04. Subsequently I have updated my packages. When I updated glslang-dev from 11.8.0 to 14.0.0 I noticed that a lot of headers went away.

Below is a comparison of the headers in each version (I removed the preceding ./usr/include/ from each one to save space):

Ubuntu 22.04 (v11.8.0)

All of the missing headers appear in the source repository for this package https://git.launchpad.net/ubuntu/+source/glslang/tree/glslang?h=applied/ubuntu/noble

1. No LSB modules are available.
Description: Ubuntu 24.04.2 LTS
Release: 24.04

2. glslang-dev:
  Installed: 14.0.0-2
  Candidate: 14.0.0-2
  Version table:
 *** 14.0.0-2 500
        500 http://us.archive.ubuntu.com/ubuntu noble/universe amd64 Packages
        100 /var/lib/dpkg/status

3. I expected all the headers to be there.

4. There is a subset of the expected headers [13/66].

Thanks for reporting.

I can confirm this based on the filelist in 24.04 (https://packages.ubuntu.com/noble/amd64/glslang-dev/filelist), it also seems to be the case for newer releases. Attached a bug watch for a corresponding report in Debian, but unfortunately no more insight on what caused this issue.
