===== 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 ^
| audio/lame | Fails to build |  | 58 |  |
| databases/mysql57-client | Fails to build |  | 316 | ''%%/usr/include/c++/v1/__config:1141:6: error: "No thread API"%%'' |
| java/bootstrap-openjdk8 | Needs porting |  | 554 |  |
| lang/go | Needs upstreaming |  | 510 | - Sources: https://github.com/MikaelUrankar/go/tree/freebsd_riscv64 ; does **not** require COMPAT_FREEBSD11 \\  - Prebuilt bootstrap: https://github.com/dmgk/go-bootstrap/releases/tag/go1.18beta2-1679-g4bdf93a078 \\  - lang/go-devel port: https://github.com/dmgk/ports-riscv64 ; set DEFAULT_VERSIONS+=go=1.19-devel in /etc/make.conf |
| lang/gcc10 | Fails to build |  | 899 | See [[https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251403|PR 251403]] |

==== Common Build Failure Types ====

As seen by [[/MarkLinimon|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 | [[https://cgit.FreeBSD.org/src/commit/?id=9d4104b214963bb3371ada05cae8006940121634|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:

<code>
pkg install -y qemu-user-static
service qemu_user_static enable
service qemu_user_static start
</code>

Please refer to the %%FreeBSD%% Handbook [[https://docs.freebsd.org/en/books/handbook/ports/#ports-poudriere|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:

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

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

<code>
$ poudriere jail -j 14riscv64 -u -x
</code>
