The solution of lacking libudev.so.1
Due to the update of `libudev0` and its associated library `libudev.so.0` to `libudev1`, node-webkit isn’t able to run on older distributions such as:
- Ubuntu 12.10
- Fedora 17
- Derivatives of the above
…and possibly others. Until your distribution is updated to the current `libudev.so.1`, the following solutions should provide a stopgap measure for packaging your applications.
1. Create a local symlink to `libudev.so.0`
Install `libudev0` if needed. Now create a local symlink to `libudev.so.0`. On Ubuntu for example, run from the directory where nw files are extracted:
# ln -s /lib/$(arch)-linux-gnu/libudev.so.0 ./libudev.so.1
Then create a shell script to run nw:
#!/bin/sh
LD_LIBRARY_PATH=/home/omi/nw:$LD_LIBRARY_PATH ./nw $*
As you are only modifying local contents of node-webkit directory, this option should not have an impact on the overall stability of your system.
2. Use a wrapper shell script for your application.
In this method, we rename the binary executable file as `myapp-bin`, and then create a shell script named `myapp` as the following. Users will then run the `myapp` file to launch your application.
#!/bin/bash
MYAPP_WRAPPER="`readlink -f "$0"`"
HERE="`dirname "$MYAPP_WRAPPER"`"
# Always use our versions of ffmpeg libs.
# This also makes RPMs find our library symlinks.
export LD_LIBRARY_PATH=$([ -n "$LD_LIBRARY_PATH" ] && echo "$HERE:$HERE/lib:$LD_LIBRARY_PATH" || echo "$HERE:$HERE/lib")
exec -a "$0" "$HERE/myapp-bin" "$@"
Creating a symlink for your package in the postinstall script
In the postinstall script of your DEB or RPM package, run the following script to create a local symlink. Use this together with the previous wrapper script.
#!/bin/bash
paths=(
"/lib/x86_64-linux-gnu/libudev.so.0" # Ubuntu, Xubuntu, Mint
"/usr/lib64/libudev.so.0" # SUSE, Fedora
"/usr/lib/libudev.so.0" # Arch, Fedora 32bit
"/lib/i386-linux-gnu/libudev.so.0" # Ubuntu 32bit
)
for i in "${paths[@]}"
do
if [ -f $i ]
then
ln -sf "$i" /opt/myapp/libudev.so.1
break
fi
done
