[SOLVED] ERROR building clang10

hay · 2024-07-08 17:33:00

Hello,

What I'm acutally trying to do is to run hashcat on Arch (or rather crack a bcrypt file (john failed, so trying hashcat)). To do this I think I need an OpenCL implementation for my CPU (would prefer to not use the GPU due to nvidia issues), and I found the beignet AUR. However I need clang10, which I'm currently in the process of building.

I clone the git from https://aur.archlinux.org/clang10.git and create with

 makepkg -si

Unfortunately I recieve

 ==> Starting prepare()...
mkdir: cannot create directory ‘build’: File exists
==> ERROR: A failure occurred in prepare().
    Aborting...

What might the problem be? Anything I can provide to further help debug the issue?

I have tried removing the folder and rebuilding to no avail.

While making this post I tried modifying the MAKEPKG with some... eh... not so smart modifications (change mkdir BUILD -> mkdir -p), I then recieved the issue:

 ninja: build stopped: subcommand failed.
==> ERROR: A failure occurred in build().
    Aborting...

This error only occured once, now I get the first issue again when trying to run

 makepkg -si

Any and all help is appreciated
Thx

Clean your build dir, or build in a clean chroot.

For the second error, we need the actual error, not just the result of the error.

thanks for responding

I'm kinda in deep waters here as I don't know what I'm doing entirely...

I' havent built with in a clean chroot before... I'm trying to follow the instructions over at DeveloperWiki:Building_in_a_clean_chroot.

When I run

 makechrootpkg -c -r $CHROOT

inside of the clang10 directory

I end up with some missing dependencies

==> ERROR: 'pacman' failed to install missing dependencies.
==> Missing dependencies:
  -> llvm10
  -> cmake
  -> ninja
  -> python-sphinx
  -> python2

However all of those are already installed.

I try to pre-install them with

$ makechrootpkg -c -r $CHROOT -I ninja-1.12.1-1-x86_64.pkg.tar.zst -I python2-2.7.18-8-x86_64.pkg.tar.zst -I python-sphinx-7.3.7-2-any.pkg.tar.zst -I llvm-10.0.1.src.tar.xz -I cmake-3.30.0-1-x86_64.pkg.tar.zst -I llvm10-libs-10.0.1-3-x86_64.pkg.tar.zst

?

But I get

Have you tried building llvm10 with LTO disabled? https://aur.archlinux.org/packages/llvm … ent-897984
Edit:
Instead of disabling LTO using fat lto objects appears to work:
diff for llvm10

diff --git a/PKGBUILD b/PKGBUILD

   cmake .. -G Ninja \

diff for clang10 (clang10 will build without these changes but beignet might need the LTO changes, the python2 changes were so I could avoid building it)

Programs that are in repos don't need to be added with -I , but you made in error in the command .

Removing the entries that are in repos to mke the error stand out more

-I python2-2.7.18-8-x86_64.pkg.tar.zst -I llvm-10.0.1.src.tar.xz -I llvm10-libs-10.0.1-3-x86_64.pkg.tar.zst

Hay, please take a good look and tell us what the error is.

Thanks to everyone for replying.

I found out that I' was in need of the package

 pocl 6.0-2

for hashcat to function.

So my original problem is kinda sorted.

For the thread itself.. I have not managed to properly install clang10.

I followed loqs instructions and modified the PKGBUILD file per his instructions, but during makepkg -si first the web browser crashes, before terminal eventually crashes. Multiple attempts tried.

Hay, please take a good look and tell us what the error is.

I tried using .src instead of .pkg it seems like.

Note: I tried creating the makepkg -si in normal mode again instead of a clean chroot...

I will update if a clean chroot install helps solve the problem after modifying the PKGBUILD file.

loqs · 2024-07-12 15:43:23

Was there anything in the journal after the crashes that might indicate the causes?

fspkwon · 2024-07-31 23:54:38

this said blah blah im a horrible reader <-
although i did learn a bit about cmake <-

Both disabling LTO and applying the diff I provided worked for me. Please post the PKGBUILD if you have made any changes from clang10 along with the invocation of makepkg you used and its full output.

fspkwon · 2024-08-01 00:34:22

this one said blah blah blah let me try to fix it myself whether i was right or not -crunch- the world will never know

Do either of the solutions I have provided work for you?

fspkwon · 2024-08-03 17:17:46

ill see if thats what and try to help with the issue <- yeah it works after building it with a 20gb tmpfs my swap partitions 40gb and have 16gb ram : so the patch and needs a bigger tmpfs than usual: so follow that little edit ruling out python and changing the useflags <- and then make a bigger tmpfs and itll build just fine ill go ahead and test beignet since thats where i think people were complaining from: beignet has built perfectly fine: now as for that guy giving me the stare over there<-..... lol whats wrong with xnine-git now..
tmpfs /tmp tmpfs rw,nodev,nosuid,size=20G 0 0

Retried and package created succesfully with

 makepkg -Si

 ==> Source package created: clang10 (Wed 20 Nov 2024 01:10:30 PM CET)

loqs · Yesterday 13:01:24

 makepkg -Si

Did you intend to build a source package or did you mistype

 makepkg -si
