Subject: bug#52913: 0ad only builds fine with a specific version of mozjs
Date: Fri, 31 Dec 2021 09:17:25 +0000	[thread overview]
Message-ID: <87y241azi0.fsf@kitej> (raw)

[-- Attachment #1: Type: text/plain, Size: 4903 bytes --]

The 0ad package checks the version of mozjs and throws an error if it is
not exactly the version it expects. This check is done in
"source/scriptinterface/ScriptTypes.h" and it currently requires version
78.6 of mozjs. As Guix has mozjs 78.15 instead, 0ad fails to build.

Patching "ScriptTypes.h" to remove the check and compile with mozjs 78.15
doesn't work, the build phase fails with:

What would be the best way to fix this?
 - keep a mozjs-78.6 package around just for 0ad
 - patch 0ad to fix the compatibility issues with mozjs 78.15
 - use the mozjs version bundled in the 0ad sources

WDYT?
