Bug ID: 56642
           Summary: wine doesn't build on risc-v
           Product: Wine
           Version: 8.10
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Keywords: source
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Ubuntu

The GNU Compiler farm has a couple risc-v machines available.

Wine doesn't get very far, though:
austin@cfarm92:~/wine$ ./configure
checking build system type... riscv64-unknown-linux-gnu
checking host system type... riscv64-unknown-linux-gnu
...
config.status: executing tools/makedep commands
In file included from tools/makedep.c:34:
tools/tools.h: In function 'get_default_target':
tools/tools.h:451:2: error: #error Unsupported CPU
  451 | #error Unsupported CPU
      |  ^~~~~

Since Windows doesn't (yet?) support risc-v, it would be a winelib only
platform. I don't know if that's still something that we intend to support or
not..

There are no plans to do a winelib-only port, that's not useful.

It would be interesting to do an ARM64EC-style port, but that will require a PE
compiler.

In that case, I think we should stop advertising it in the FAQ:
https://wiki.winehq.org/FAQ#Where_can_I_get_further_help?

https://wiki.winehq.org/FAQ#Is_Wine_an_emulator?_There_seems_to_be_disagreem...
"Winelib can be used for porting Windows application source code to other
operating systems that Wine supports to run on any processor, even processors
that Windows itself does not support."

https://wiki.winehq.org/Winelib_User%27s_Guide#What_is_Winelib?
"Another benefit is that a Winelib application can relatively easily be
recompiled on a non-Intel architecture and run there without the need for a
slow software emulation of the processor."

If winelib for non-Windows supported architectures is no longer supported, then
we should remove these references / advertise it as such. Currently, for me,
the top result on stackoverflow mentions that it's supported, for example:

Sure, it can be removed. It's certainly still possible to use the Wine code to
port an app to some other platform, but that's not something that's going to
work out of the box in upstream Wine. There are not enough use cases to make it
worth the maintenance effort.
