[SOLVED] Mozplugger Yaourt Build errors

Hello everyone,

According to a comment from:

https://aur.archlinux.org/packages.php?ID=9458

I'm supposed to make sure libx11 and/or its symbols are installed correctly because the problem is not with PKGBUILD.

I tried reinstalling libx11 and its dependencies with pacman -S.

However, that didn't work, so how do I fix the undefined references error?

See:

Modified PKGBUILD (Only URL and Source are modified: )

http://pastebin.com/0tX5RrqG

Yaourt Install Output:

http://pastebin.com/XkRvtyng

Notes:
-You'll see that I'm using yaourt to install mozplugger.  I also tried compiling mozplugger myself; however, when I typed the command "make", a similar "undefined reference" error occurred.

Re: [SOLVED] Mozplugger Yaourt Build errors

I believe fs4000's comment was only half right.  The problem is not with the PKGBUILD, but with the upstream source.  Specifically there is a problem in the input to the configure script which results in -lX11 not being added to the Makefiles.

This sort of problem is generally 'patched' in a PKGBUILD.

I'll see if I can find an easy fix.  I'll edit this post in a bit with more info.

edit: I tried the PKGBUILD you posted above.  It worked perfectly for me.  I even verified that the Makefile includes the -lX11 flag.  I was too quick to judge fs4000's comment, it seems to be correct.  I suspect the problem is on your end.

Do you have problems compiling anything else from the AUR that requires X11?  Can you try building with makepkg instead of yaourt and post any error output?

edit2: Did you see this in your output

==> WARNING: Building package as root is dangerous.
 Please run yaourt as a non-privileged user.

.  Heed that warning.

Re: [SOLVED] Mozplugger Yaourt Build errors

It seems to be the configure script that doesn't add -lX11 for you. I don't know how this comes.

Just another try: Do you have the whole base-devel group installed?

I did have base-devel installed.  In fact, I typed "pacman -S base-devel" just to check.

And, I have a similar error after I typed "make."  However, ./configure was just fine.  (See output below: )
Note that I typed "su" and then ran ./configure and make.

Output after I typed "./configure":

How do I make sure yaourt runs in a safer and more secure way?

Login as a regular user.  Don't use sudo.

edit: I see you also ran configure and make as root.  This is a bad habit.  Running as root will not solve problems, it will just make it more likely that any problems you encounter could be catastrophic.  Even without makepkg/pacman, a normal configure and build process would run compile and make as a regular user, using root privileges only for the `make install` step.  As you should not even be trying to install until the build is successful, you should be doing EVERYTHING as a regular user until the problem is solved.  It is possible to cause such problems by loggin in as root as your environment, settings, and configs are all different.

In short: root privileges do not solve problems, they magnify them.

Thanks for the tip, Trilby.  This time, I used ./configure and make as a regular user.  Same problem occurs.

See:

Re: [SOLVED] Mozplugger Yaourt Build errors

Can you also post the Makefile generate by the configure script.

Here are copies of the makefiles (I typed ./configure first)

Re: [SOLVED] Mozplugger Yaourt Build errors

You could try (in the directory with the Makefile)

sed -i 's/^XLIBS.*/XLIBS=-lX11/'
make

Configure is not adding the lX11 flag as noted above, and you can see in the configure output the line

checking for XDisplayName in -lX11... no

which should be a yes.  (Mine has yes).

As a check can you run these two commands and post their output.

 pkg-config --libs x11
pacman -Ql libx11 | grep libX11.so

I haven't tried something like that yet.  I'll try it.

Edit:
I downloaded mozplugger-chromium from the AUR (requires libX11) and this original undefined error still existed:

mozplugger-helper.c:(.text+0x149): undefined reference to `XGetErrorText'
...
mozplugger-helper.c:(.text.startup+0x12a9): undefined reference to `XSync'

Re: [SOLVED] Mozplugger Yaourt Build errors

Oops, I dropped half the sed command.  That should have beeb

sed -i 's/^XLIBS.*/XLIBS=-lX11/' Makefile
make

Sorry.  Typing faster than I'm thinking.  The sed command is just a quick way of editting the Makefile to add the -X11 switch where it is needed.

Re: [SOLVED] Mozplugger Yaourt Build errors

OK, its slow ... but that's progress.

By any chance did anything go wrong in your glibc update?

One check:

pacman -Ql glibc | grep libdl.so.2

Re: [SOLVED] Mozplugger Yaourt Build errors

There's the problem.

At some point recently you did a partial upgrade.

A pacman -Syu, followed by dealing with any resulting errors, should fix this right up.

Re: [SOLVED] Mozplugger Yaourt Build errors

Umm... This mozplugger issue actually connects with the glibc issue.  Pacman -Syu won't work because glibc cannot be upgraded yet.  I have to make sure glibc is upgraded.  This is actually more difficult than it seems.

Yes.  Glibc is an extremely important package, especially when you want to compile something.  Frankly, if you botched that update and your system is still running, you should count yourself as lucky.  Fix it.

Read the news, the wiki, and other forum posts.  Then fix it.

Re: [SOLVED] Mozplugger Yaourt Build errors

Ok, I solved the glibc problem and my mozplugger install was successful.

Here is the link I used:

https://wiki.archlinux.org/index.php/De … iki:usrlib

What I did was:

1. I backed up my data (i.e. /etc , /home , /var , pacman database, list of installed packages, and anything else I needed.) because I could break my system.

See for more details on backup:

https://wiki.archlinux.org/index.php/En … _Stability

2. I found which packages were owning files by typing:
find /lib -exec pacman -Qo -- {} +

Many of the files in /lib were unowned by any package.  So, I just deleted those unowned files.  Of course, the manual work of deletion was rather tedious...

Note that if any file is listed as being owned by any of your packages (besides glibc), please upgrade those packages so that its files are in /usr/lib.

3. After all those files were deleted, (The /lib folder was probably the only thing that was unowned.  However, no file was certainly unowned.) I typed: pacman -Su.  This is to upgrade glibc.

4. That glibc upgrade was successful.  However, I had some text 'errors,' (I don't remember what they were.) so I restarted my computer and those 'errors' were gone.

5. I just installed mozplugger.  Now everything's working well again.

Thanks for all your help, anyway, because I initially didn't know an unupgraded glibc caused problems.

P.S. If my solution does not help, here is a reference:

https://bbs.archlinux.org/viewtopic.php?id=145006

You might be going back to the very topic that you were on, which is titled "glibc update refusing to proceed. File ownership problem"
