missing libX11.so.6

[Mithgol]

The purpose is to build and test node-sqlite3 for node-webkit on Travis CI (TryGhost/node-sqlite3#252).

For that purpose I download https://s3.amazonaws.com/node-webkit/v0.8.4/node-webkit-v0.8.4-linux-ia32.tar.gz and unpack it, and then run nw, but it says:

nw: error while loading shared libraries: libX11.so.6: cannot open shared object file: No such file or directory

(see that Travis CI log, line 1736).

On the same system, when I download https://s3.amazonaws.com/node-webkit/v0.8.4/node-webkit-v0.8.4-linux-x64.tar.gz and unpack it, and then run nw, it runs happily without errors.

Does it mean that 32-bit node-webkit won't run on a 64-bit Linux system, or there's still hope?

[Mithgol]

Having run ldd nw, I've got the following on my log (lines 1727—1763):

I have used “Search the contents of packages” at http://packages.ubuntu.com/ and discovered (through a trial-and-error process) the following commands which, if run before node-webkit, make it possible to run 32bit node-webkit on 64bit Travis CI Linux:

sudo apt-get -y install libx11-6:i386
sudo apt-get -y install libglib2.0-0:i386
sudo apt-get -y install libgtk2.0-0:i386
sudo apt-get -y install libatk1.0-0:i386
sudo apt-get -y install libgdk-pixbuf2.0-0:i386
sudo apt-get -y install libcairo2:i386
sudo apt-get -y install libfreetype6:i386
sudo apt-get -y install libfontconfig1:i386
sudo apt-get -y install libxcomposite1:i386
sudo apt-get -y install libasound2:i386
sudo apt-get -y install libxdamage1:i386
sudo apt-get -y install libxext6:i386
sudo apt-get -y install libxfixes3:i386
sudo apt-get -y install libnss3:i386
sudo apt-get -y install libnspr4:i386
sudo apt-get -y install libgconf-2-4:i386
sudo apt-get -y install libexpat1:i386
sudo apt-get -y install libdbus-1-3:i386
sudo apt-get -y install libudev0:i386

Here's an example of a Travis CI job that could run node-webkit 32bit successfully:

https://travis-ci.org/mapbox/node-sqlite3/builds/18827549

[katanacrimson]

@Mithgol pretty sure you can combine that all onto one line. apt-get install [packages, space delimited] should work

[Mithgol]

Yes.

But if Travis CI configuration changes (providing a different set of available packages) then one line would be harder to debug (it would stop the whole installation on the first unknown package it encountered).

Having several lines means you may identify all lines that were successful and all lines that failed, even if failures are multiple. For example, in that log I could identify two missing packages at once (line 2106, line 2132) and remove them (TryGhost/node-sqlite3@9c555c3). If I were to remove them one-by-one, I'd have to spend at least ten more minutes between errors (as you may see in that log's header, Travis job's duration was 9 minutes 9 seconds).
