Ports Status on RISC-V

Tracking build status of important/desired ports on RISC-V.

There is now an official package builder at http://beefy7.nyi.freebsd.org/ .

Packages are built for stable/13 (ports' quarterly branch) and main (ports' main branch).

The Most Notable Build Failures

Port	Status	Required For	Blocks	Notes

Common Build Failure Types

As seen by MarkLinimon 202101201:

Count	Failure	Suggested Fix	Comments
7	qemu: uncaught target signal		Often 11 (Segmentation fault), sometimes 6 (Abort trap) - core dumped
7	C compiler cannot create executables		or related "checking whether the C compiler works... no"
7	ld: error: can't create dynamic relocation R_RISCV_HI20 against symbol
6	checking thread safety of required library functions... Segmentation fault		possibly subcase of "C compiler cannot create executables" above
5	error: use of undeclared identifier 'FP_X_INV'
2	relocation R_RISCV_ALIGN requires unimplemented linker relaxation; recompile with -mno-relax
2	ldd: <xyz>.so: not a FreeBSD ELF shared object	teach ldd to parse ELF notes	possibly fixed

Cross-Building Ports

There is some support for cross-compiling ports via poudriere(8) and qemu-user-static. This method works by emulating a RISC-V userspace with QEMU, so it is faster than building within an emulated system, but slower than building natively. The QEMU userspace emulation is imperfect.

Install and start qemu-user-static first:

pkg install -y qemu-user-static
service qemu_user_static enable
service qemu_user_static start

Please refer to the FreeBSD Handbook entry about poudriere if you are unfamiliar with the tool or need to set it up.

The following command will create a new poudriere jail set up to cross-compile ports for the riscv.riscv64 target:

$ poudriere jail -c -a riscv.riscv64 -x -j 14riscv64 -m ftp -v 14.0-CURRENT -x

The -x argument instructs poudriere(8) to build native cross-toolchain. Make sure to specify it when updating the jail as well, like so:

$ poudriere jail -j 14riscv64 -u -x
