Clang fails to build after repo merge

[Beeblebrox-BSD]

Hello I cloned a fresh shallow repo of merged tree (drm-next) with flag "--depth 1". Clang fails to build, as confirmed by,

• No /usr/bin/cc in fresh DESTDIR target
• cc on host has date of last build (pre-merge)
• work directory has empty tmp/usr/lib/clang/3.9.1 (sub folders are empty), same with tmp/legacy/usr/lib/Clang./3.9.1
• Explicitly setting CLANG knobs in /etc/src.conf has no effect, neither does disabling ccache.

I ran in to this problem while trying to debug build problems in the poudrière jail. Currently have no Xorg, was trying to re-build all relevant ports before proceeding with debug. Regards.

• Clarification: The problem is not with a shallow git repo, as I ran "git --unshallow" and got same resuılt. Also, "make toolchain" does nothing to resolve the issue.

• Update: With latest kernel, if I kldload drm, then radeonkms vt works fine as expected, however dmesg does repeatedly show: [drm:radeon_vga_detect] VGA-1: probed a monitor but no|invalid EDID

When I start xorg, kernel panics and crashes (using vesa for xorg atm) I am emailing Matt separately for the kernel dumps, should he want them.

Hi,

Can you re-test using the latest drm-next branch?

--HPS

Hello Peter, I tried the following two alternatives but clang still does not build

• Renamed /etc/src.conf to buildworld with defaults
• Explicitly set all clang flags in src.conf I only see usr/bin/c++filt and folders usr/lib/debug/usr/lib/clang, usr/lib/clang have sub-folders which are just empty.

I tried several independent make calls, idk whether this helps:

• make -C usr.bin/clang => In file included from /asp/git/src/contrib/llvm/tools/clang/tools/driver/cc1_main.cpp:18: In file included from /asp/git/src/contrib/llvm/tools/clang/include/clang/Driver/DriverDiagnostic.h:13: In file included from /asp/git/src/contrib/llvm/tools/clang/include/clang/Basic/Diagnostic.h:18: /asp/git/src/contrib/llvm/tools/clang/include/clang/Basic/DiagnosticIDs.h:53:10: fatal error: 'clang/Basic/DiagnosticCommonKinds.inc' file not found

  include "clang/Basic/DiagnosticCommonKinds.inc"

• make -C lib/clang => ===> libllvm (all) llvm-tblgen -gen-attrs -I /asp/git/src/contrib/llvm/include -d llvm/IR/Attributes.inc.d -o llvm/IR/Attributes.inc /asp/git/src/contrib/llvm/include/llvm/IR/Attributes.td llvm-tblgen: error opening llvm/IR/Attributes.inc:No such file or directory *** Error code 1

Hi, I'm just using world from 12-current and only the kernel from DRM next. --HPS

Clang build is disabled in this repo by various tweaks, I have a patch if you want to build it but I'm leaning towards just grabbing the kernel as I still get the same DiagnosticCommonKinds.inc error with it.

Thanks for the info. I'll go with kernel-only on the repo as HPS had also advised.

You can close the PR if you wish.

PS advise if anyone wants the kernel dumps as noted previously; I don't want to paste the link publicly.

Regards.
