I tried hard to compile the new xorg-server - but to no avail...

I see no options to change the failing behaviour. I am surprised to see a reference to some 86-hw as I am on a raspi. I never had issues compiling the xorg-server. But now even xorg-server-21.1.7 fails at the same place. Something changed the behaviour of the installation...
Comment 1 Mike Gilbert gentoo-dev 2023-04-03 14:56:13 UTC
Please attach a full build log and set the status to UNCONFIRMED.
Comment 2 Peter Serbe 2023-04-03 19:01:56 UTC
Created attachment 859487 [details]
build.log

sorry, i didn't notice that adding the log failed, as the log was a wee bit too big.
Comment 3 Peter Serbe 2023-04-14 13:57:24 UTC
I tried to compile x11-base/xorg-server-21.1.7 on a non-updated raspi, which succeeded. The differences in the build job for ../xorg-server-21.1.x/hw/xfree86/int10/helper_exec.c are small - but they might be a hint.

I've got for the working complile:
----------------------------------------------------
-Ihw/xfree86/x86emu
...
-D_X86EMU
-DNO_SYS_HEADERS
-Wno-format-nonliteral
----------------------------------------------------

Whereas for the failing compile I had one, that was missing in the OK-case:
----------------------------------------------------
-D_VM86_LINUX
----------------------------------------------------

I have no clue what triggered the chance. On the machine, where the xorg-server compilation fails, I have three packages installed, that may or may not be related:

x11-drivers/xf86-input-libinput-1.2.1
x11-drivers/xf86-video-dummy-0.4.0
x11-libs/libXxf86vm-1.1.5
Comment 4 Peter Serbe 2023-07-10 16:01:43 UTC
I compared the failed compile task with the corresponding one from a (ARM) machine, where the compile succeeds. The differences were:
In the failed compile I have:
"...  -Ihw/xfree86/x86emu ...  -D_X86EMU -DNO_SYS_HEADERS -Wno-format-nonliteral ..."
whereas I read for the successful compile:
"...  -D_VM86_LINUX ..."

Furthermore I read in INT10.HOWTO:
"Currently   defines  are   available  for vm86-mode under  Linux and x86emu. They may be activated  by defining _X86EMU or _VM86_LINUX respectively."

So I am pretty sure, that the issue is, that on this machine xfree86 does not correctly determine the current platform. After a bit of experimentation I got a successful compile by modifying the xorg-server-ebuild by adding:

src_configure() {
   ...
   emesonargs+=(
      -Dint10=x86emu
   )
   ...
)

I was not able to find out, how meson derives the configure options - but I still have the impression, that there is an underlying bug rather than (as still possible) configuration error on my side.
Comment 5 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-01-03 21:13:36 UTC
Your emerge --info has aarch64 for the personality which implies you forgot to run linux32.
Comment 6 matoro archtester 2024-01-03 21:55:19 UTC
Confirmed, this goes away with proper setarch.
Comment 7 Peter Serbe 2024-04-18 16:47:47 UTC
I finally found out, what happened.

The RaspberryPi 4 will boot the 64 bit kernel and run the 32 bit Gentoo without any complaint. Everything seems to run fine, it is just, that the Meson build system assumes, that it was invoked in a 64 bit system and it then decides not to add /xfree86/x86emu/libx86emu.a.p to its target list.

The fix is to add 'arm_64bit=0' to config.txt in the Raspi /boot directory, as otherwise the 64 bit kernel will load - and an innocent fool like me won't notice at all...
So yes, the hint at AARCH64 was very right. But even this did not make me seeing the issue until today.
