Description Pascal Jäger 2021-11-11 11:14:06 UTC

Created attachment 750339 [details]
Build.log with DISTCC_VERBOSE=1

When I emerge nss-3.72 (also tried it with nss-3.70 on different machine) with distcc and set distcc verbosity to DISTCC_VERBOSE=1 the build fails with `../coreconf/rules.mk:285: *** missing separator.  Stop.` right at the beginning. 
If I set DISTCC_VERBOSE=0 it works fine. 

I think this problem is the one mentioned here upstream:
https://distcc.github.io/faq.html (search for 'Make fails with "file not found"')

This is just my interpretation of the bug and I can only base this on the taste of my coffee today and not on any particular research I have done: I think this is a race condition during the build and with DISTCC_VERBOSE=1 the timing is changed slightly, changing the outcome of the race.

Depending on the outcome of this bug I suggest adding a remark on the wiki page of distcc maybe?

This is also the case for libxcrypt, libsdl2, cogl, cairo and libxslt.
(and probably others I have not tried yet)
