Solved 10.0 stable upgrade to 11.0 stable problem

[rdunkle]

I am trying to update FreeBSD 10.0 STABLE r267746 to FreeBSD 11.0-STABLE.

When I ran make buildworld I got a seg fault.
I assumed this was due to old clang.

clang -v

FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512
Target: x86_64-unknown-freebsd10.0
Thread model: posix
Selected GCC installation:

I installed llvm38 from ports.
pkg info | grep llvm

clang38-3.8_1                  C, Objective-C, and C++ compiler (use devel/llvm38)
llvm38-3.8.1_5                 LLVM and Clang

I changed the src.conf file:
cat /etc/src.conf

CC=/usr/local/bin/clang38
CXX=/usr/local/bin/clang++38
CPP=/usr/local/bin/clang-cpp38

No more seg fault, but new error.
make buildworld throws this error:

In file included from /usr/src/lib/libc/db/btree/bt_close.c:43:
/usr/src/lib/libc/../../include/stdio.h:63:9: error: unknown type name '__off64_t'; did you mean
      '__off_t'?
typedef __off64_t       off64_t;
        ^~~~~~~~~

Do you have something in your /etc/make.conf? I think that /etc/src.conf should be empty too. Clang 3.8 is automatically build when upgrading.

The edit to /etc/make.conf is the same as the /etc/src.conf if you want all ports to use clang. My /etc/make.conf only has a 3 lines for sendmail flags.

https://wiki.freebsd.org/BuildingFreeBSDWithClang
Clang 3.8 is built during the new kernel.
The clang that is used by make buildworld is controlled by /etc/src.conf

Update first to the latest stable/10, the newest revision at this moment is 307803. There is a known problem with the upgrade path to stable/11 that needs a newer clang first to be able to build stable/11 successfully.

I updated to 10.3-STABLE r307822. Then was able to build releng/11.0 r307822
