[Lib2geom-devel] build on Ubuntu 12.04

[Christian <cp...@gm...>]

Hi folks,

I am just new to this mailinglist and just exploring the library a bit.

I tried compiling lib2geom-0.2.0 on Ubuntu 12.04 (x86_64) and got:

[  1%] Building CXX object src/2geom/CMakeFiles/2geom.dir/matrix.o

Despite all the Warning from cmake, I thought perhaps worth sharing...


Fixes:
  - I replaced all appearances of size_t by std::size_t in utils.h (line 85)
         void binomial_coefficients(std::vector<std::size_t>& bc, std::size_t n);
- utils.cpp in function
     void binomial_coefficients()

after
     sudo aptitude install libgtk2.0-dev

and another make it built!

Thx
