Cannot compile Feisty AMD64 (incompatible libXt.so)

[Adam Bolte]

Following the instructions (​http://virtualbox.org/wiki/Linux%20build%20instructions), compilation always fails on the AMD64 Feisty distribution (using a Intel C2D 2Ghz CPU). Subversion and source for 1.4.0 produce the same result.

Successfully generated 'AutoConfig.kmk' and 'env.sh'.
Source 'env.sh' once before you start to build VBox:

  source env.sh
  kmk

To compile the kernel module, do:

  cd ./out/linux.amd64/release/bin/src
  make

Enjoy!

I have also tested without the --with-gcc/gxx options (which uses gcc version 4.1.2 by default). Although the build instructions mention not to use gcc4, the error when used is the same. Tested again on both SVN 3302 and 1.4.0.

Also tested with the --with-gcc=/usr/bin/gcc-3.3 and --with-gcc=/usr/bin/g++-3.3 options (which uses gcc 3.3.6 for Ubuntu). The errors (again the same for both 1.4.0 and SVN 3302) are:

A different compilation error, but the gcc version should be compatible according to the build instructions ("3.2.3 or later").

[Michael Thayer]

As a workaround for the libXt problem, create a symlink from libXt.so.6.0.0 to libXt.so. You will have to do the same for libX11.so.

[Frank Mehnert]

No! Please install the package ia32-libs. I will add an appropriate check to configure.

[Adam Bolte]

Howdy!

So it sounds like the ia32-libs version is being used, but ia32-libs does not include the system link you expect. I'll add the system link in /usr/lib32 to libXt.so and see how I go. Thanks guys.

[Adam Bolte]

I also created a system link for libX11.so, and the thing compiled. Thanks again!

[Frank Mehnert]

Michael is right, the link is mandatory. I have no idea why the ia32-libs package does not contain that link.

[fernando]

I'm building VirtualBox-1.5.4_OSE in a Gutsy AMD64 and had the same problem. This ticket led me to the error (missing symlinks) and I've to add two of them manually to complet the build without errors:

root@<my_server>:/usr/lib32# ln -s libX11.so.6.2.0 libX11.so root@<my_server>:/usr/lib32# ln -s libXTrap.so.6.4.0 libXTrap.so

You're doing a good work - thanks!

Fernando

[fernando]

Actually I forgot to mention two other necessary symlinks. Here's the complet list :

ln -s libX11.so.6.2.0 libX11.so

ln -s libXTrap.so.6.4.0 libXTrap.so

ln -s libXt.so.6.0.0 libXt.so

ln -s libXtst.so.6.1.0 libXtst.so

[Bart]

Creating the soft links mentioned above is a bad practice. There is a very good reason why shared objects have a version number suffix: this allows multiple binary incompatible shared objects to coexist on the same system. The problem is in the VirtualBox OSE makefiles: these makefiles should link on libX11.so.6 instead of libX11.so.

[Frank Mehnert]

I don't agree. Every normal shared library for x86_64 on Ubuntu has these links installed. Linking is normally done with -lX11 and this works well if the link exists. And the version dependency for the library the link is pointing to is added by ld when doing this as well.

[Frank Mehnert]

Obsolete.
