[gecode-users] Help -- about Gecode::Space::operator new

[Kayler Yao]

hi,
    There has only that error
"projectdlg.cpp(198) : error C2660: 'Gecode::Space::operator new' : function
does not take 3 arguments"
    the error line is
" GenSolModel * m = new GenSolModel (temp);"
    Yeah,it may be so. i have to use another way ---"GenSolModel a(temp);
GenSolModel *m =&a;" to instead of it. Luckily, it can run OK. For the
reason of time, i will hang it for a while . I will find this
bug and uncover it to the sun in my free time. Thanks for your reply.
