undefined symbol: lxc_strerror

[Jafaral]

Hi,

I'm experimenting with this package but I keep getting this error:

$ruby test.rb
/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require': /var/lib/gems/2.3.0/gems/ruby-lxc-1.2.1/lib/lxc/lxc.so: undefined symbol: lxc_strerror - /var/lib/gems/2.3.0/gems/ruby-lxc-1.2.1/lib/lxc/lxc.so (LoadError) from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:inrequire'

'

OUTPUT of nm:
$nm /var/lib/gems/2.3.0/gems/ruby-lxc-1.2.1/lib/lxc/lxc.so | grep lxc_str
U lxc_strerror

obviously it is undefined in lxc.so and it is expected to be defined at runtime. Who is supposed to define it? what am I missing ?

$lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

$ruby --version
ruby 2.3.1p112 (2016-04-26) [arm-linux-gnueabihf]

I also tried on another Ubuntu machine but got the same error above. Same ruby version but it is x86 instead ot arm.

$ruby --version
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]

Thanks in advanced for any help.

@andrenth Do you have any idea what is causing this?

[Jafaral]

I see this error message on two ubuntu 16.04 AMD64 desktop machines, but it works on Ubuntu 16.04 armhf after I switched to an ubuntu server from desktop version. The three machines have the same lxc version (2.0.4), same ruby-lxc 1.2.1. The only difference is ruby version. The machine that I don't have problem with is running ruby 2.3.0 while all others are running 2.3.1p112 as I mentioned above.

My work around for now was to just declare a dummy lxc_strerror() function in lxc.so to avoid the undefined symbol issue.

I've merged your pull request and released version 1.1.2. Sorry for the delay.
