Ccache build error with 21.02.0-rc1 -- which fix is likely?

djadair · April 29, 2021, 1:04am

When attempting to rebuild 21.02.0 for an EA7500 V1 target on a RHEL8 host I fail quite quickly due to a known build failure with tools/ccache.

The root cause is that the MANUAL.adoc source file contains non-ascii characters. Curiously this only happens during the OpenWRT build -- if I generate the docs manually using host tools and makefile it works fine so I think the difference is LANG=C -vs- LANG=C.utf8.

Soome locales like `LANG=fr_FR.iso885915@euro make` can't handle UTF-8 single- a…nd double-quotes: ``` $ LANG=fr_FR.iso885915@euro make ... asciidoc: FAILED: MANUAL.adoc: line 529: unexpected error: ...

I was wondering which "fix" would be most likely for the eventual 21.02 release ?

Backport patch to replace smart quotes with normal quotes ? ( have only tested rejected version )
Once again revert to ccache 3.7.1 ?
Change build system to use utf8 LANG ? ( Seems too brave for me ).
Host change ??? Seems like official build servers work for some reason.

My goal is to set up a build environment as close as possible to the 21.02 stable release once it exists. Oh dang. Should have used branch instead of tag urgh ...

Updated: I messed up the link to actual patch. It does work but does not apply cleanly -- there is an extra sentence added since 4.1.
