[SOLVED] Rails: Error running wkhtmltopdf -- (error while loading shared libraries)

Rails: Error running wkhtmltopdf -- (error while loading shared libraries)

When my app runs (or when I run from commandline) the wkhtmltopdf command I get the following error: (showing it from command line)

#> wkhtmltopdf 
wkhtmltopdf: error while loading shared libraries: libXrender.so.1: cannot open shared object file: No such file or directory

I noticed the lib is indeed in the /usr/lib folder but not the /lib folder. Does it matter which one of these it is in? Is there any way to get it to recognize it?

#> ls -l /usr/lib/libXrender.so*
lrwxrwxrwx 1 root root    19 Feb 17 07:20 /usr/lib/libXrender.so -> libXrender.so.1.3.0
lrwxrwxrwx 1 root root    19 Feb 17 07:20 /usr/lib/libXrender.so.1 -> libXrender.so.1.3.0
-rwxr-xr-x 1 root root 39184 Jan 29  2010 /usr/lib/libXrender.so.1.3.0

#> ls -l /lib/libXrender.so*
ls: cannot access /lib/libXrender.so*: No such file or directory

I also checked dependencies of the lib

# ldd /usr/lib/libXrender.so.1
    libX11.so.6 => /usr/lib/libX11.so.6 (0x00002b9cb5afd000)
    libc.so.6 => /lib/libc.so.6 (0x00002b9cb5e04000)
    libXau.so.6 => /usr/lib/libXau.so.6 (0x00002b9cb6143000)
    libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0x00002b9cb6347000)
    libdl.so.2 => /lib/libdl.so.2 (0x00002b9cb654d000)
    /lib64/ld-linux-x86-64.so.2 (0x0000555555554000)

This is running on an EngineYard gentoo server

Solution

The Unix packages x11-libs/libXext and x11-libs/libXrender are dependencies

Gentoo:

sudo emerge libXext libXrender

PDFkit wiki also explains in more detail how to get wkhtmltopdf working on engine yard. PDFkit wiki

Debian or Ubuntu:
