g2o build issue #82

Open bgyooPtr opened 6 years ago

bgyooPtr commented 6 years ago

Hello I have a problem building the dependency g2o. I am using Ubuntu 16.04, ros kinetic and opencv 3.2-dev.

First, I downloaded g2o and started the build using the build script (make_deb.sh). I got the following error:

In file included from /usr/include/c++/5/random:35:0, from /home/bgyoo/library/g2ofork/g2o/stuff/sampler.h:38, from /home/bgyoo/library/g2ofork/g2o/examples/data_fitting/curve_fit.cpp:30: /usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

error This file requires compiler and library support \

So I enabled c ++ 11 and rebuilt it. and then I got the error:

What is the fundamental solution?

Edit: got the first answer wrong, sorry

The script make_deb.sh is not needed (I'll remove it to avoid confusion), just do the regular cmake based installation (mkdir build; cd build; cmake ..; make install). Even better, follow (or use) the installation script linked in the Readme file.
