Hi,
To save time on my Raspberry Pi I would like to build FreeBSD using a llvm pkg

My /etc/make.conf:

Any thoughts on how to fix this?
Compiling with the in tree llvm does work properly.
Did it work with exactly this git revision? I suspect an issue with the
recent google test update rather than an llvm16 issue. Note that for
every sync to github we build the tree with the llvm16 port (all be it
on amd64 by default).
It's worth noting one difference between your configuration and the
CI one: We don't set CC and friends directly. Instead we use
CROSS_TOOLCHAIN=llvm16.

Hi,
What I would like to accomplish is this:
CROSS_TOOLCHAIN=llvm16
WITHOUT_TOOLCHAIN=yes
yes | make delete-old delete-old-libs
make buildworld buildkernel
So I can run a system with only external toolchain.
But doing this quickly errors out because /usr/bin/cc does not exist and the
build uses that even though CROSS_TOOLCHAIN is set. To circumvent that I set
CC, etc. instead of CROSS_TOOLCHAIN.
Regards,
Ronald.
Hi,
I found what was going on. Passing CC=/usr/local/llvm16/bin/clang does not pass
the -target, --sysroot and -B option. If I set those in CFLAGS everything
compiles fine.
What I do now is this:
pkg -j ${JAIL_NAME} install -y ${CROSS_TOOLCHAIN} byacc
jexec ${JAIL_NAME} sh -c "yes | /usr/bin/make CC=${LLVM_DIR}/bin/clang
LD=${LLVM_DIR}/bin/ld.lld -C /usr/src delete-old delete-old-libs"
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/llvm16/bin/clang cc
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/llvm16/bin/clang CC
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/llvm16/bin/clang++ c++
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/llvm16/bin/clang-cpp cpp
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/llvm16/bin/llvm-objcopy objcopy
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/llvm16/bin/ld
cd ${JAIL_PATH}/usr/bin && ln -fs ../local/bin/yacc
jexec ${JAIL_NAME} /usr/bin/make -C /usr/src -j${NUM_CPUS}
CROSS_TOOLCHAIN=llvm16 WITHOUT_TOOLCHAIN=yes buildworld buildkernel
This builds fine also. Because CC is not set SYSROOT is just the default.
Any advice on how to make set CC and use the proper sysroot instead of the
(ugly) symlinking?
And why do parts of buildworld use CROSS_TOOLCHAIN and other parts don't?
Regards,
Ronald.
