[epiar-devel] The successes and failures of a night with MSVC

[Димитър Станчев]

 Hi,

On what version of MSVS did you managed to compile it? I tried cmake build with 2010 express and something gave an error. (2008 works) 

It comes out like a "undefined behavior" rigth? I watched a presentation on the subject "Here Be Dragons: C++ Undefined Behavior". Check it out, if it bring you an idea, its useful to know it.

Since MinGW didn`t detect this, I think it`s not a significant thread. May be MSVC knows better but we can leave it with #ifdef until we solve it betterwise.

I can ask my lectors about this problem but won`t be on my PC to try it for 2 weeks.
