Description O. Hartmann 2015-06-15 08:06:43 UTC 
After I udated sources from r284336 to >r284404, I'm unable to "buildworld buildkernel" a system.

The buildworld process bails out at different steps depending on the settings in /etc/src.conf - but either with or without a custom /etc/src.conf, the sources do not build anymore. A very early failure is triggered if one is using the options
[...]
#
CXXFLAGS+=              -std=c++11
#
WITH_CLANG_FULL=        YES
WITH_CLANG_EXTRAS=      YES
WITH_LLDB=              YES
[...]

After a few initial steps, my system stops building with the error I attached below as an extraction.

Avoiding any /etc/src.conf (my removing it) makes the buildprocess bailing out later in the process.

The problem is seen on all platfoprms I use/maintain and also seen by many other users.


regards,
Oliver

Comment 1 Larry Rosenman freebsd_committer freebsd_triage 2015-06-15 10:18:49 UTC 
I'm seeing this still at r284408
Comment 2 Tijl Coosemans freebsd_committer freebsd_triage 2015-06-15 10:46:09 UTC 
This bug is invalid imo.  You cannot add -std to CXXFLAGS like that.  It specifies what language the source code is written in.  It's a developer choice, not a user choice.
Comment 3 Larry Rosenman freebsd_committer freebsd_triage 2015-06-15 12:29:03 UTC 
I have not added ANYTHING since my last successful buildworld.  
Something BROKE THE BUILD HERE.
Comment 4 O. Hartmann 2015-06-15 13:20:38 UTC 
The CXXFLAGS= option speeds things up. The failure is still present in r284409.

This was broken (rather obviously) by r284345, the meta-mode commit:

Since r284345 is a very large commit, it is tricky to see what exactly broke it, but it looks like custom CXXFLAGS are now mangled when passed to mkdep for C++ files.  In the above lines, see the part where there are *no* -I flags to the mkdep invocation for all the .cpp files.

Obviously, this has always worked just fine, and while not exactly 100% supported, as Tijl notices, there is absolutely no need to break it.

Assigning to sjg so he can help figure out what went wrong. :)

Is this now working properly again with the latest changes in head?
Comment 8 Larry Rosenman freebsd_committer freebsd_triage 2015-10-24 15:25:57 UTC 
I haven't seen the problem in a long time.

Can we close this?

I have not seen this a couple of weeks right now with most recent CURRENT.
