1043954 - Intermittent: fatal error C1083: Cannot open include file: 'prenv.h': No such file or directory

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Mike Hommey [:glandium]]

This is due to building in config/nspr during the compile tier retriggering an export (it's nspr's build system that does that, apparently), which re-exports headers, and creates a race with other compilations using the header in dist/include.

[Mike Hommey [:glandium]]

yeah, there's a libs:: export in nsprpub/config/rules.mk :(

Comment 2

[Mike Hommey [:glandium]]

Ah, I had forgotten about that feature of the nspr build system:

# libs - obsolete.  Now a synonym of "export".

So hacky. This new directory won't be packaged, will it?
