Building RISC-V toolchains on FreeBSD 11.0

[Kimura Masayuki]

Hi,

I'm trying to build FreeBSD for RISC-V on FreeBSD 11.0 platform.

I use FreeBSD 11.0 vagrant box and reference https://wiki.freebsd.org/riscv .

I checked out riscv repositories clone https://github.com/freebsd-riscv/riscv-gnu-toolchain, revision c875e2fa338f712a3138bf74fa897702c7883231

And I faced trouble of building bbl as follows.

checking build system type... x86_64-unknown-freebsd11.0

checking host system type... riscv64-unknown-freebsd11.0

checking for riscv64-unknown-freebsd11.0-gcc... riscv64-unknown-freebsd11.0-gcc

checking whether the C compiler works... no

configure: error: in `/home/vagrant/riscv-pk/build':

configure: error: C compiler cannot create executables

See `config.log' for more details

and, I checked build result of riscv-gnu-toolchain. 

For example, when I tried to cross-compile using riscv64-unknown-freebsd11.0-gcc. I think crt1 and some libraries are not compiled:

% cat main.c

int main()

{

  ;

  return 0;

}

% riscv64-unknown-freebsd11.0-gcc main.c

/home/vagrant/riscv/lib/gcc/riscv64-unknown-freebsd11.0/6.1.0/../../../../riscv64-unknown-freebsd11.0/bin/ld: cannot find crt1.o: No such file or directory

collect2: error: ld returned 1 exit status

Do you know any ways to fix them?

Thanks.

Hi Kimura:

Build freebsd world & kernel first, then build BBL

Hi

thanks Yukishige-san -- I reported to commit author.

Kimura-san you can revert it locally for a while.

thanks

Hi Yukishige, Ruslan

Thank you for your support. I had tried some commit revisions shown in https://wiki.freebsd.org/riscv, such as r303660, r303908. 

I will use reverted revesion. Thank you.

Thanks.

Alternatively you can just set

setenv WITHOUT_SHAREDOCS yes

thanks

Hi, Ruslan-san,

Setting WITHOUT_SHAREDOCS=yes seems better to me than reverting the commit.

Anyway. I'll update my build script to set it.

Thank you for ur quick feedback.

[Kimura Masayuki]

Hi Ruslan, Yukishige,

I tried them, and MYOBJDIR shoud be

setenv MYOBJDIR "/home/${USER}/obj/riscv.riscv64/home/${USER}/freebsd-riscv/"

not, 

setenv MYOBJDIR "/home/${USER}/obj/riscv.riscv64/home/${USER}/dev/freebsd-riscv/"

at https://wiki.freebsd.org/riscv

Thanks.
