I have some trouble emerging it, there's a binary package somewhere to bootstrap it?
I think the monomini runtime required to bootstrap it without an installed runtime does't work...

erm67,
| Code: | arm64-build ~ # gcc-config -l
[1] aarch64-unknown-linux-gnu-6.4.0
[2] aarch64-unknown-linux-gnu-7.3.0
[3] aarch64-unknown-linux-gnu-8.1.0 *
arm64-build ~ # binutils-config -l
[1] aarch64-unknown-linux-gnu-2.29.1
[2] aarch64-unknown-linux-gnu-2.30 *
arm64-build ~ # emerge -1av =mono-4.8.0.524 |
builds and installs on native arm64 hardware.
Its in my binhost
I'm trying 5.4.1.6 now
As you say, I can configm that 5.12.0.226 can't execute mono.
-- edit --
mono-5.4.1.6 also fails with | Code: | Microsoft (R) Visual C# Compiler version 2.6.0.62309 (d3f6b8e7)

The funny thing is that exactly the same version works fine on archlinux arm, maybe a different commit is checked out..

erm67,
mono-5.12.0.226 cross compiles for arm64.
That took me by surprise since I was expecting it to attempt to run arm64 C# code on the build host.

Maybe it is caused by pie used by default in profile 17, i think i will go to the beach and try later something else ????????
I think there something related to pie either in the official or the overlay relatwd yo pie that is commented out.

erm67,
I think the build system for newer mono is broken an arm64.
As some versions build and some don't and cross compiling works, all on systems with pie as a default, I don't think the problem is pie

Too bad, mono <5.12 doesn't work with ncurses >5.9 ...............
https://github.com/mono/mono/issues/6752
downgrading ncurses mono works perfecly but still cannot emerge the 5.12.
Apparently fedora 28 ships mono 4.8 and ncurses 6.1 so they must have backported the patches.

Ok mono 4.8.0 is not usable because the version shipped by gentoo do not supports terminfo2 and apparently profile 17 requires ncurses-6.1 (I could not downgrade it at least)
The good news is that the bug on aarch64 is known and there is a workaround:
https://github.com/mono/mono/issues/7017
| mono developers wrote: | | The best way to workaround that is to pass --with-csc=mcs to autogen.sh so it uses mcs instead of Roslyn. |
I tested and mono 5.12 successfully compiles and works on aarch64 passing --with-csc=mcs, the mono sources shipped by gentoo are already patched for terminfo2, so that is not a problem, maybe I will try to patch the ebuild and submit a bug report.
BTW mono 4.8.0 should be masked or patched if profile 17 requires ncurses >= 6

Just in case someone needs mono on arm64:
patch the ebuild with:
