Bug 541368 – sys-devel/llvm-3.6.0_rc4 Error: open CFI at the end of file; missing .cfi_endproc directive

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Petros 2015-02-25 19:15:36 UTC]

Certain packages on my system demand LLVM-3.6. I unmasked it and voila...I now it is not stable, not even testing but I think you should be aware of the situation.

[Comment 1 Petros 2015-02-25 19:27:45 UTC]

bugs.gentoo.org doesn't allow me to submit build.lof (file too large). What can I do in order to help you see it?

[Comment 2 Mike Gilbert 2015-03-03 02:48:07 UTC]

What packages fail to build?

To attach large build logs, compress them with gzip or xz.

LLVM itself.

llvm-3.6.0 (final) is in the tree. Have you tried that version?

Well I tried to emerge sys-devel/llvm-3.6.0::gentoo and it didn't complete compilation. I am attaching an build.log

Thanks for the report, can you post your emerge --info and also how much memory/swap do you have on this system? The build log says:
> virtual memory exhausted: Cannot allocate memory
So you almost certainly ran out of memory (llvm keeps getting bigger with each release)

Yes of course I will post emerge --info.

I have not swap on my system. My RAM's size is 3.8GB (4096MB normally but built'in graphics are using some). I have noticed many packages dying because of RAM and I think I should lower my parallel builds.

Did running the build by itself and/or adding swap help? If not, you should try with simpler cflags/ldflags (especially the link parts can use a bit of memory)

[Comment 12 Bernard Cafarelli 2015-09-02 11:56:27 UTC]

Cleaning some bugs now that 3.7.0 is near (and 3.6.1/3.6.2 did not generate similar bugs), don't hesitate to reopen if you still have the problem (with simpler CFLAGS/LDFLAGS)

I added some RAM (8Gb total) and LLVM builds without problem. I should think of the memory in the first place.

Thanks for the confirmation :)
