GLIBC_2.11 not found

[mihhail-lapushkin]

Hello,

One Grunt plugin is using your tool and on linux-x86-64 it is throwing this error:

/path/to/node_modules/grunt-contrib-imagemin/node_modules/pngquant-bin/vendor/pngquant: /lib64/libc.so.6: version `GLIBC_2.11' not found

Linux is a CI machine. I contacted the admin and here is what he replied:
I ran updates to glibc from our Enterprise Linux distribution but it did not help with this problem. :(

First I wanted to post this as a Grunt plugin issue, but I guess it is more related to the pngquant itself.
Can you give some tips on resolving this?

It looks like you have pngquant executable that is not compatible with your
Linux distribution or version of the distribution.
This could happen if you compiled it on another machine and copied the
binary to different flavor of Linux.

Delete this executable and try installing package from pngquant.org website
or compile it yourself.

@pornel is right, this is more related to the npm package node-pngquant-bin that bundles the incompatible pngquant binary (I guess the default is for Ubuntu).

The problem seems to be that when node-pngquant-bin is being installed and the tests are failing it doesn't recompile correctly.

Try to execute this in the /path/to/node_modules/grunt-contrib-imagemin/node_modules/pngquant-bin:

npm test (you need to have tools like make and npm mocha)

and post the results.

Also take a look here imagemin/pngquant-bin#2
