[dcoeurjo]

This should be fixed in the last version of the DGtal project on GITHUB. Could you please update your copy (git pull) and test it again ?

[dagonzalez]

It still fails:

[dcoeurjo]

Could you please give me info on your compiler ?

[dagonzalez]

Yes of course:

g++ (GCC) 4.6.1 20110819 (prerelease) Copyright © 2011 Free Software Foundation, Inc.

[dcoeurjo]

Ok we have a fix... it will be pushed into the DGtal/master soon. I'm closing the issue, thanks for the report

[dcoeurjo]

It seems to be ok now, could you test the last version of the repo ?

[dagonzalez]

It builts fine thanks.
