LLVM11: llvmtools: LLVM fails to build llvm-tblgen #14

dslm4515 · 2021-06-27T16:06:08Z

Re-built llvmtools and made sure libcxx did not require libatomic.

now llvm/clang for llvmtools fails to build:

Added -DLLVM_TABLEGEN=/cgnutools/bin/llvm-tblgen to cmake command. Not sure if this will cause llvm binaries to have GCC dependencies.

So far build has surpassed 220 built targets!

Could you add a file "../files/libunwind-llvm12/compact_unwind_encoding.h" for libunwind in BMLFS repo, because I want to try build llvm 12 and catch errors, too?

I actually have llvm12 working for bmlfs. Let me check which branch...

dslm4515 · 2021-06-27T20:05:44Z

Ops. I forgot to extract the missing header from libunwind! Sorry. Misread

andzai1995 · 2021-06-27T20:06:24Z

There is some code in file build-scripts/llvm12.build:

# Fix missing header for lld, https://bugs.llvm.org/show_bug.cgi?id=49228
mkdir -pv tools/lld/include/mach-o
cp -v ../files/libunwind-llvm12/compact_unwind_encoding.h tools/lld/include/mach-o

When I cloned BMLFS repo, this file is absent.

It is the same file like in $LLVMSRC/projects/libunwind/include/mach-o? Or this file is different?

it’s the same

dslm4515 · 2021-06-27T20:50:59Z

I’ve uploaded the file to master branch of BMLFS

clang-tblgen is built but cannot execute...due to libraries not loading from llvmtools/lib:

$ LD_LIBRARY_PATH=/llvmtools/lib ldd   build/bin/clang-tblgen 
        /lib/ld-musl-x86_64.so.1 (0x7f75911d9000)
        libexecinfo.so.1 => /llvmtools/lib/libexecinfo.so.1 (0x7f7591038000)
        libc++.so.1 => /llvmtools/lib/libc++.so.1 (0x7f7590f6d000)
        libc++abi.so.1 => /llvmtools/lib/libc++abi.so.1 (0x7f7590f10000)
        libunwind.so.1 => /llvmtools/lib/libunwind.so.1 (0x7f7590efd000)
        libc.so => /lib/ld-musl-x86_64.so.1 (0x7f75911d9000)

perhaps, I should have added LD_LIBRARY_PATH=/llvmtools/lib:/cgnutools/lib:/usr/lib:/lib when compiling? Maybe llvm-tblgen would have been built too?

owl4ce · 2021-06-28T14:50:47Z

is this issue related to build llvm in llvmtools?

owl4ce · 2021-06-28T14:51:49Z

is this issue related to build llvm in llvmtools?

For LLVM 12, I just fine while building. See #12 (comment)

Now moving to chroot steps. I'll report if an issue appeared.

dslm4515 · 2021-06-28T14:53:40Z

yes for llvm11 (master). First build fails after 4mins for llvm-tblgen not built or unable to execute. So i reconfigured with using llvm-tblgen from cgnutools. Build progresses for 58mins then fails on unable to execute built clang-tblgen

Before you were contributing, i was working on LLVM12 branch...lol, but i was stuck on libcxx of llvmtools (by now, you, and others already fixed that). I thought i'd work on master (llvm11) to have it updated with latest software versions of June 18th 2021.

Hopefully, no GCC dependencies for llvmtools!

owl4ce · 2021-06-28T15:02:32Z

I use GNU Make for LLVM, so mostly never install ninja (and less dependencies) until entering chroot (meson). I prefer Samurai.

May I ask. What packages that requires meson?

dslm4515 · 2021-06-28T15:09:28Z

Good point. I like ninja for the clean text output... although, make can do that too.

Make is pretty common and less dependencies, i'd likely switch from ninja to make

Right, Ninja can show the total of source code and not showing the enter-close directory like Make.

Samurai looks good. I do hate how ninja is either built with python or cmake. I may replace ninja with samurai in both CMLFS and MLFS.

For CMLFS, meson is not used. It is built so that a CMLFS system can build packages that use meson as their build system.... I forgot the original reason meson was added to LFS.

I think so!

owl4ce · 2021-06-28T15:30:25Z

In LFS Appendix, meson is used when building Systemd.

Try this, and don't forget to enable --zlib-compat.
https://github.com/zlib-ng/zlib-ng

dslm4515 · 2021-06-28T15:36:12Z

Try this
https://github.com/zlib-ng/zlib-ng

I noticed hasn't been updated for a while. I suppose i'll switch to zlib-ng, just like how i dropped pkg-config for pkgconf

owl4ce · 2021-06-28T15:38:02Z

And maybe pigz instead of gzip, but pigz requires zlib (zlib-ng works too). Cons: pigz doesn't have wrapper script such as for grep (zgrep). Can be installed for both, gzip just for wrapper script if needed 😄 lol

dslm4515 · 2022-03-29T15:14:59Z

I'm closing this as I don't think anyone will want to build LLVM-11 for CMLFS.
