Icaros Desktop won't start

[ascendant]

I just installed Icaros Desktop Live! hosted on my Arch Linux computer. I have an old Intel Core i7 920, and AMD Radeon RX480, and 12Gigs of ram.

Now I saw that the linux-hosted-install.sh wanted to run apt-get, which is not relevant to Arch Linux, so I made sure that I had all of the equivalent packages installed before launching.

I cd into my installation folder, type icaros and this is what I get:

i run icaros desktop hosted on ubuntu based distribution and works fine

[deadwood]

Hi,

Try doing:

$ gdb ./Arch/linux/AROSBootstrap

Then "r" command which should run AROS. Once it crashes, do "bt" command and paste here please.

[ascendant]

Thanks for your assistance. I have attempted, but I'm sorry to say that I was not able to get much info. First, it doesn't crash. It just hangs indefinitely. Eventually I Ctrl-C it, and print out the backtrace and see it's waiting on another process:

Code: [Select]

Indeed, it has spawned a second AROSBootstrap process. I have attempted to attach to that process, but GDB complains:

And a backtrace doesn't provide much:

If you are willing to dig deeper into this, I can build for you a version with debug symbols. It won't be exactly the same as Icaros, but maybe it will give you a hint where to look for problem. Alternativelly you can build your own version of hosted. It's pretty straighforward, just follow these instructions: https://github.com/deadw00d/AROS/blob/alt-abiv0/INSTALL.md

I followed the build steps, but got this error:

Code: [Select]

Assembler messages:

make[1]: *** [Makefile:38: /home/jlm/code/AROS_build/toolchain-alt-abiv0-i386-build/bin/linux-x86_64/gen/host/tools/MetaMake/mmake.o] Error 2

So I did this:

Code: [Select]

cd toolchain-alt-abiv0-i386-build/tools/MetaMake
make all
cd -
Rerunning rebuild.sh got past that. So I think that there may be a missing dependency that's not visible unless you rebuild from scratch. There's more errors, but I'll work through them and reply when I have some more useful info.

[deadwood]

Hmm, I never seen MetaMake fail to build. :/ Please note that every time you run ./rebuild.sh it literally rebuilds (meaning deletes your build directories and starts from scratch). If you want to recompile just one target, you need to enter the build directory and invoke make <target>

As for dependencies, I use a Debian-based distro, so indeed there can be some missing for Arch.

Let me know if you have any more issues. I'll try to assist.

[ascendant]

The next build error was due to the fact that Arch's default Python is Python 3, but genmf.py is written for Python 2. So I edited AROS/tools/genmf/genmf.py , and added a 2 at the end of the first line.

Next, I encountered this error:

Code: [Select]

Unescaped left brace in regex is passed through in regex; marked by <-- HERE in m/^\@strong{ <-- HERE (.*)}$/ at /home/jlm/code/AROS_build/toolchain-alt-abiv0-i386-build/bin/linux-x86_64/Ports/host/gcc/gcc-4.6.4/gcc/../contrib/texi2pod.pl line 319.

I backslash escaped the braces on that line of the file. Thanks for the tip on how to continue without starting from scratch. So now I'm in toolchain-alt-abiv0-i386-build and running make. Otherwise this latest fix is overwritten when I run rebuild.sh.

Next:

Code: [Select]

gcc.texi:89: warning: @tex should only appear at the beginning of a line
gcc.texi:209: no matching `@end tex'
gcc.texi:209: no matching `@end multitable'

I manually patched toolchain-alt-abiv0-i386-build/bin/linux-x86_64/Ports/host/gcc/gcc-4.6.4/gcc/doc/gcc.texi following the instructions at this link: https://gcc.gnu.org/legacy-ml/gcc-patches/2013-09/msg02100.html

Then another problem with Python, so I changed toolchain-alt-abiv0-i386-build/config/make.cfg to call Python 2.

Now I'm getting this error:

Still trying to figure out the solution to this one.

[ascendant]

I got past the latest error by putting

Code: [Select]

#ifndef _STAT_VER
#define _STAT_VER 0
#endif
in AROS/arch/all-unix/devs/hostdisk/hostdisk_host.h and AROS/arch/all-unix/filesys/emul_handler/emul_unix.h

Next I edited AROS/rom/dos/genstrings.py to point to Python 2. But that was a red herring. I needed to edit the PYTHON define in toolchain-alt-abiv0-i386-build/bin/linux-x86_64/gen/host/config/host.cfg

Now it fails to link dos.library:

Code: [Select]

         U err_Strings dos_init.c:0

I'm not sure where this is expected to be defined. Even on a Ubuntu system, it is not defined anywhere in /usr/include.

It is generated by rom/dos/genstrings.py script, which seem to be invoked by rom/dos/mmakefile.src

[ascendant]

Thanks. I thought my change to run genstrings.py using Python 2 would fix it, but I see it does not. I removed bin/linux-i386/gen/rom/dos/errorlist.h, which was an empty file anyway, and reran. Oddly, I don't think it even got to the point to link dos.library, and I found this error:

Code: [Select]

   64 | extern void __clear_cache(char *begin, char *end);
      |             ^~~~~~~~~~~~~
cc1: all warnings being treated as errors

So I changed the declaration to match what is expected and reran make.

Almost made it. Now just a problem with the final link:

[ascendant]

I think buf in AROS/arch/all-hosted/bootstrap/bootstrap.h should be declared extern, and then defined somewhere else to ensure it is only compiled once and therefore no duplicate copies of that symbol will exist for the final linking.

I just guessed that since it is a rather generic variable to be defined, not even just declared, in a header file, that maybe it wasn't even needed, and commented it out. That gets past the error.

[magorium]

It is indeed declared as extern in bootstrap.h in ABIv11 (https://github.com/deadw00d/AROS/blob/master/arch/all-hosted/bootstrap/bootstrap.h) but lacks the modifier on branch alt-ABIv0 (https://github.com/deadw00d/AROS/blob/alt-abiv0/arch/all-hosted/bootstrap/bootstrap.h).


Good catch !

Okay, I finally got it all compiled. When I run it, the following appears in an infinite loop:

Maybe it doesn't like my monitors. I have two monitors, the main one at 2560x1600, and a secondary rotated to 1080x1920.

That's actually good progress! The number of issues you had to overcome is however quite troubling. I hope updates that I plan will fix them.

Now, onto the issue itself. It seems AROS did not detect your directory and AROS system directory. First, check if you have AROS.boot file in alt-abiv0-linux-i386/bin/linux-i386/AROS.

Then run AROS through gdb

Code: [Select]

$ cd alt-abiv0-linux-i386/bin/linux-i386/AROS
$ gdb ./Arch/linux/AROSBootstrap
"r"

Once it crashes, issue following commands in gdb command prompt:
"loadbt"
"bt"

and let's see where the crash is.
