qt5 fails to build on Ubuntu 14.04. Log: https://gist.github.com/3a6081a34f436d37581e

• Ran brew update and retried your prior step?
• Ran brew doctor, fixed as many issues as possible and retried your prior step?
• If you're seeing permission errors tried running sudo chown -R $(whoami) $(brew --prefix)?

Message:

You might need to install dependency packages, or pass -qt-xcb.

[sjackman]

Can you quote the relevant lines of the gist and link to them?

[rwhogg]

Comment updated.

[sjackman]

Is this with or without linuxbrew/xorg/xorg installed?

[rwhogg]

Without. It looks like having libxcb installed will allow it to finish building successfully; if so, I'll add the dependency and make a PR.

[rwhogg]

Scratch that; it looks like qt5 thinks it's installed even though it's not. Apparently it leaves behind an empty lib directory in its Cellar.

[tseemann]

@sjackman I do have linuxbrew/xorg/xorg installed and qt5 just failed to build with brew gcc-5.3 on RHEL7:

/usr/bin/ld.gold: error: .obj/qabstractanimation.o: unsupported reloc 42 against global symbol QAbstractAnimation::staticMetaObject

Are you using the linker /usr/bin/ld.gold intentionally? Do you have binutils installed?

[tseemann]

I do have binutils installed - no idea why. I assumed it was a dependency of something?

So I unlinked it, and now I get a new error:

[sjackman]

binutils is a dependency of glibc. Having binutils installed by Linuxbrew is a good thing. I was trying to figure out why it was using your hosts ld.gold instead.

Is xcb/xcb_icccm.h installed by one of the linuxbrew/xorg/xorg formula?

[tseemann]

find /bio/linuxbrew -name xcb_icccm.h returns nothing :(

And here's the xcb folder:

ls /bio/linuxbrew/Cellar/libxcb/1.11.1/include/xcb

bigreq.h     dri2.h     randr.h   screensaver.h  xc_misc.h  xf86dri.h   xkb.h       xtest.h

[sjackman]

It looks like it's supposed to be provided by xcb-util-wm. Is it installed?
See http://www.linuxfromscratch.org/blfs/view/svn/x/xcb-util-wm.html

[DoomHammer]

Shaun, what's your opinion on making gcc --with-glibc a dependency of all builds (as opposed to bottles)?

[sjackman]

I'd prefer to use the host GCC if it provides GCC 4.4 or better. I think that folk get annoyed if they ask to install something small like gawk, and it installs an entire compiler toolchain. Of course as we bottle more, that's going to be the effect anyway, so maybe we should just cut to it and make GCC a dependency of everything. On newer systems like Ubuntu 14 Precise with glibc 2.19 or better I'd prefer to use the host glibc. Why do you ask? Because of the magic specs file provided by gcc?

[tseemann]

I did brew install xcb-util-wm and get a new error:

xcb.cpp:42:27: fatal error: xcb/xcb_image.h: No such file or directory`

So I brew install linuxbrew/xorg/xcb-util-image and get a new error:

xcb.cpp:43:29: fatal error: xcb/xcb_keysyms.h: No such file or directory`

Then brew install linuxbrew/xorg/xcb-util-keysyms and get a Qt error:

The "reloc 42" issue is a linking issue, I am using brew binutils and brew gcc-5.3.

Here are my gist-logs: https://gist.github.com/1542fb74473d12752d41741c45682d22

[rwhogg]

I did brew install xcb-util-wm and get a new error:

xcb.cpp:42:27: fatal error: xcb/xcb_image.h: No such file or directory`

So I brew install linuxbrew/xorg/xcb-util-image and get a new error:

Those sound like possible missing dependencies in linuxbrew/xorg. I'll take a look at that.

Those sound like possible missing dependencies in linuxbrew/xorg. I'll take a look at that.

Hmm, apparently not that simple. @tseemann, if it's not too much to ask, mind opening up another issue on https://github.com/linuxbrew/homebrew-xorg/issues with the gist-log that got you those xcb errors?

[rwhogg]

This issue was moved to Linuxbrew/homebrew-core#146
