mono is currently at 2.4, is this still an issue?

[jean-philippe.humbert@…]

I have tried again and I have the same Problem With Macports 1.7.1:

10.4 or 10.5? And I'm guessing PowerPC? Can you rerun with debug enabled and attach the output:

sudo port -d install mono  2>&1 | tee ~/Desktop/mono_debug.txt

[jean-philippe.humbert@…]

I have attached the log file. I have tested on a IMAC G5 with Leopard

i also added an attechment. mono 2.4_0 under os-x 10.5 on ppc.

after some private re-investigation of this error and the headers to consider, i went - taking for granted the portfile​ made use of all patchfiles - to double-check that patch-mono-mini-mini-ppc.h.diff did good changes and when i had seen that it did
i had to do the changes manually - had, considering that i went to check the portfile not until the port compiled successfully with these changes
it turns out the patch-mono-mini-mini-ppc.h.diff was never appended to 'patchfiles'

attaching an updated portfile with patch-mono-mini-mini-ppc.h.diff added after patch-mono-mini-mini-x86.h.diff under the 'platform darwin 9' block as in:

platform darwin 9 {
    configure.cflags-append    -D_NONSTD_SOURCE
    configure.cxxflags-append    -D_NONSTD_SOURCE
    patchfiles-append \
        patch-interp.h.diff \
        patch-sys-mman.c.diff \
        patch-mono-mini-mini-x86.h.diff \
        patch-mono-mini-mini-ppc.h.diff \
        patch-libgc-darwin_stop_world.c.diff
}

(since i complied mine with manual changes to the source this portfile could be considered untested)

else just a lot of warnings; among common C inconsistencies (and even more so in the c#sharp compiling) this, that seemed odd to me, but what do i know:

 ** Warning: System.dll built without parts that depend on: System.Xml.dll

btw i wanted to install this because i couldn't find mdb in mono's precomiled os-x download and calling mono_object_describe in gdb produces:

debug-helpers.c: No such file or directory.

but now i cant find mdb in this port either, gdb /opt/local/bin/mono produces a lot of warnings about not finding files in /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_mono/work/mono-2.4.2.3/mono/mini and p mono_debug_print_vars produces

 Unable to call function "mono_debug_print_vars" at 0x5aed0: no return type information available

*sigh*

pardon my grammar/vocabulary - im a little tired (plus i'm an occasionally quirky swede)

[ryandesign (Ryan Carsten Schmidt)]

Do you still see the problem with mono 2.6.3?

[jean-philippe.humbert@…]

Sorry I can´t test it anymore because I only have Intel-Macs now.

[ryandesign (Ryan Carsten Schmidt)]

Is this still a problem with mono @2.10.6?

[raphael-st (Raphael Straub)]

Replying to ryandesign@…:

Is this still a problem with mono @2.10.6?

Yes, I still have the same problem with mono @2.10.6 on Mac OS X 10.5.8 ppc.

[jeremyhu (Jeremy Huddleston Sequoia)]

has this been reported upstream? I doubt anyone here will be fixing it.

[ryandesign (Ryan Carsten Schmidt)]

Is this still a problem with mono @3.2.5? If so please report it to the developers of mono.

[jean-philippe.humbert@…]

Sorry but after 5 years I don't use mono anymore and don't one a powerpc computer to test 3.2.5 again.

[khepler]

I've had mono @2.10.9_0 installed on my PowerBook G4 for an indeterminate amount of time. Trying to build @3.2.5 fails with:

sgen-os-mach.c: In function 'sgen_suspend_thread':
sgen-os-mach.c:85: error: incompatible types in assignment

I tried a couple different version of GCC in addition to the default. GCC 4.5 fails during the build without printing an error. GCC 4.8 doesn't pass the configure checks ("C compiler can't create executables"). Can try Clang 3.2 and 3.3 upon request (I have both installed), but I don't believe 3.3 works on PowerPC.

Ok, I see the same problem on Leopard ppc. Please ​report this problem to the developers of mono so they can fix it, and tell us the URL of the bug report once you've done that.

Defect raised:

​https://bugzilla.xamarin.com/show_bug.cgi?id=19013

[ryandesign (Ryan Carsten Schmidt)]

They have indicated that Mono 3 requires Lion or newer, thus excluding PowerPC machines.

[barracuda156]

Looks like this port was broken forever. Anyway, here is the issue: ​https://github.com/mono/mono/issues/21649
