Vitualbox won't compile after changing the system to LTO #435

Closed rafaelfortes closed 4 years ago

rafaelfortes commented 4 years ago

I installed a new system and after everything was up and running decided to give gentooLTO a go, so far has been great with exception of three packages that will not compile without LTO by "FLAGS-=-flto" and/or completely removing the gentooLTO optimizations (created a custom ltoworkarounds file with "FLAGS="-march=znver2 -O2 -pipe -fomit-frame-pointer") and with GOLD or BFD linkerm the results are the same. In the case of VirtualBox I tried versions 5.2.32 and 6.0.14 and one thing that I noticed is that the ebuild is forcing the use of BFD linker and when the build fails it seems to be the linker to cause it, see below the beginning and end of build.log. For chromium and powerdevil I will create separate issues later.

and of course, the output of emerge --info =virtualbox-5.2.32

Is there a way in ltoworkarounds to force the linker to be GOLD? could be some library or other package that Virtualbox depends on that also need to be compiled without LTO?

elsandosgrande commented 4 years ago
  1. You can choose which linker to use by putting -fuse-ld=[bfd/gold] in the CFLAGS, which is how I do it ( https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Link-Options.html#Link-Options )
  2. Please share your emerge --info output with us, as it seems like you are running a hardened profile
  3. skipping incompatible /usr/lib/libdl.a when searching for -ldl, where /usr/lib is for 32-bit binaries and /usr/lib64 for 64-bit ones; VirtualBox is being compiled as an amd64 (64-bit) program, while the compiler and linker are being served IA-32 (32-bit) libraries, which are not compatible (at least this is my guess from personal experience, https://bugs.gentoo.org/show_bug.cgi?id=690676 and https://bugs.gentoo.org/show_bug.cgi?id=691274 , and the little information you have currently provided us with regarding your system)

  1. BFD (GNU ld) is recommended because it is actually still supported (it was also causing some kind of trouble a few months ago, but I am unable to recall the specifics at the moment)

I hadn't noticed that the libraries were 32bit, but this wasn't happening before LTO, should I change something at the ebuild?

elsandosgrande commented 4 years ago
  1. Ebuilds have no effect on libraries
  2. Was your transition to 17.1 smooth (like mine), or did you have issues?
  3. It is recommended that you have ACCEPT_KEYWORDS=~amd64 set in your make.conf when using GentooLTO, as we do not test against the stable version of Gentoo and recommend to use the latest version of the compiler of your choice (some people are successfully using Clang instead of GCC, though I am not sure how smooth the transition was for them)
  4. What is your output of equery belongs libcrypto.so? Mine is:
 * Searching for libcrypto.so ...
dev-libs/openssl-1.1.1d-r2 (/usr/lib64/libcrypto.so -> libcrypto.so.1.1)
dev-libs/openssl-1.1.1d-r2 (/usr/lib/libcrypto.so -> libcrypto.so.1.1)

If it says bash: equery: command not found, then install app-portage/gentoolkit and try again. If you do not see a lib64 entry, your system needs troubleshooting.

Is there a way in ltoworkarounds to force the linker to be GOLD?

In short, not really.

Emerge ltoize with USE override-flagomatic. This will link a script in /etc/portage/bashrc.d to overwrite all the functions in the flag-o-matic.eclass at build time. The original eclass file is located at /var/db/repos/gentoo/eclass/flag-o-matic.eclass if you would like to take a look.

By erasing all the eclass functions, what override-flagomatic will do is remove all ebuild forced flag modifications and allow you to use all of your own. The problem with this is that it can break emerges where changing or adding a flag is needed. You can emerge ltoize with override-flagomatic, build the package, then rebuild ltoize without it so you don't have to worry about random breakages in other packages.

What I generally do is copy the package into a local overlay and edit it from there. Unfortunately, I don't think there is a one-and-done way to force a linker when it's built into an ebuild like that.

@jiblime -fuse-ld=gold

rafaelfortes commented 4 years ago
  1. Ebuilds have no effect on libraries
  2. Was your transition to 17.1 smooth (like mine), or did you have issues?
  3. It is recommended that you have ACCEPT_KEYWORDS=~amd64 set in your make.conf when using GentooLTO, as we do not test against the stable version of Gentoo and recommend to use the latest version of the compiler of your choice (some people are successfully using Clang instead of GCC, though I am not sure how smooth the transition was for them)
  4. What is your output of equery belongs libcrypto.so? Mine is:
 * Searching for libcrypto.so ...
dev-libs/openssl-1.1.1d-r2 (/usr/lib64/libcrypto.so -> libcrypto.so.1.1)
dev-libs/openssl-1.1.1d-r2 (/usr/lib/libcrypto.so -> libcrypto.so.1.1)

If it says bash: equery: command not found, then install app-portage/gentoolkit and try again. If you do not see a lib64 entry, your system needs troubleshooting.

Sorry for the late reply, didn't have time the last few days.

  1. I did not transition, installed fresh directly on 17.1
  2. I'll will try rebuilding everything with ~amd64, but it will take sometime, if it works I'll update here.
  3. Pretty much the same output 
    * Searching for libcrypto.so ... 
app-backup/spideroak-bin-7.5.0 (/opt/SpiderOakONE/lib/libcrypto.so)
dev-libs/openssl-1.1.1d-r2 (/usr/lib/libcrypto.so -> libcrypto.so.1.1)
dev-libs/openssl-1.1.1d-r2 (/usr/lib64/libcrypto.so -> libcrypto.so.1.1)

@jiblime -fuse-ld=gold

Pretty surprised tc-ld-disable-gold doesn't filter ld.gold from *FLAGS. Nice catch.

If the package still fails to compile, you can also try -fuse-ld=lld with sys-devel/lld installed

elsandosgrande commented 4 years ago

Maybe his .pc file for the library(ies) is not pointing towards /usr/lib64? That's what happened with Rubberband.

rafaelfortes commented 4 years ago

So, it took some time but recompiled my whole system with ACCEPT_KEYWORDS="~amd64"... and still have the same problem with virtualbox. (uploaded to a google drive with the full log if anyone want to take a better look https://drive.google.com/open?id=161w-wZchG8fhUR_SUOoAlfcyCbYe2-T5) Using -fuse-ld=gold apparently did not work, still got the message saying bfd was being used.

@elsandosgrande what do you mean by .pc file? don't know this extension. And if the problem is with the ebuild or something of the sort, why would only happen after I changed to LTO (it compiled fine before)?

elsandosgrande commented 4 years ago

.pc file -> pkg-config file. By "Rubberband", I am referring to this: https://bugs.gentoo.org/691274.

rafaelfortes commented 4 years ago

Checked pkg-config (didn't even know I had this, learned one more thing today :) ) and there is no .pc file for virtualbox. Virtualbox ebuild has no reference to /usr/lib or /usr/lib64 directly, only to get_libdir function. I'm kind in a loss here, don't know how to debug this, any ideas?

elsandosgrande commented 4 years ago

You don't have a VirtualBox .pc file because VirtualBox is not yet installed. Even then, it would be irrelevant, as pkg-config looks at the pc files of libraries being used. Did you look at the linked forum posts @rafaelfortes?

Anyway, the line before Please submit a full bug report is probably the actual error here, since I just saw that some packages still get that skipping incompatible output, while not failing at all. Could you please post the latter half of the build log in a GitHub gist?

rafaelfortes commented 4 years ago

@elsandosgrande created a gist as requested, included the beginning of emerge process and after around line 430 a section of the end of the build. if you need it to have more data just ask.

  1. VirtualBox strips flags. That one I didn't know. It even lies to Portage about it.
  2. I'm not seeing much of anything here. Could you attach the full log file in a reply here and check the .pc files of the libraries mentioned in those skips like I did in https://bugs.gentoo.org/691274 using equery and see if any show what is shown in the ticket I linked to?
rafaelfortes commented 4 years ago

I could not create a gist with the entire build.log file, github just gives an error, apparently it is way too long, but did upload to google drive here build.log. Checked the pc files, most libs don't have .pc files associated, only found for libssl and libcrypto, but I do have two .pc files for each, one at /usr/lib/pkgconfig and another at /usr/lib64/pkgconfig. The ones at 'lib' reference internally to '/usr/lib' and the ones at 'lib64' reference '/usr/lib64', as one would expect. The thing is, should I have these two folders with .pc files, can the linker be looking for the libraries at the wrong folder because of it? One thing, could this be cause by a bad environmental variable? maybe I'm missing a '/usr/lib64' somewhere?

elsandosgrande commented 4 years ago

All right... I am not seeing anything out of the ordinary yet and don't have the time right now to rebuild VirtualBox for the sole purpose of comparing the logs. Also, other libraries should have respective pkg-config files. For example, after running equery belongs /usr/lib/libX11.so, I got x11-libs/libX11-1.6.9 (/usr/lib/libX11.so -> libX11.so.6.3.0), from which I was able to see which package owns the library. Then, by doing equery files x11-libs/libX11-1.6.9 and looking for .pc files, I found /usr/lib/pkgconfig/x11-xcb.pc, /usr/lib/pkgconfig/x11.pc, /usr/lib64/pkgconfig/x11-xcb.pc and /usr/lib64/pkgconfig/x11.pc. To emphasize, having one mere library with a misconfigured pkg-config file was enough to bring everything down to a grinding halt in the issue ticket linked above.

@jiblime Pardon the mention, but do you have any ideas here? I am truly stumped.

rafaelfortes commented 4 years ago

So, after a few weeks of traveling for work and being busy decided to compile virtualbox again and it worked... I tried version 6.1.0 this time. I guess the issue is closed, thank you @elsandosgrande for your efforts trying to solve this, its appreciated.

elsandosgrande commented 4 years ago

I'm glad that it worked out.
