What is the problem with building on Linux, this has not been explained clearly. Does -std-C++0x not work on Linux with your 4.7.1? Clearly there is a bug in wx, and it seems to be MingW gcc compiler version dependent, because the MingW guys have hidden _strdup() and company only after a certain version when __STRICT_ANSI_ is defined, and the wx guys have yet to catch up with that change. _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
