wxCurl with c++11/gnu++11 issue I encountered

As the original post has been marked as 'Solved',I open a new thread in case noone notice my question.Thanks.

From what I can tell, the solution is that we need to shift the mingw32-make to do the following, right?

Code: Select all

mingw32-make -f makefile.gcc WX_SHARED=1 LDFLAGS=-lwldap32


I'm not a MingGW person, so I'll take your word for this. :)

When I tried to build the most recent wx2.9.x with MinGW4.7.1 + -std=gnu++11,it is fine;but after that when I tried to build wxCurl lib with the same compiler(regardless has option -std=gnu++11 or not),it failed,saying that somewhere in the src 'isnan' does not defined in that scope bla;but if I changed to MinGW4.5 without -std=gnu+11,everyting goes fine.

Appreciated for the solution,I really wanna turn to c++11 with wx.
Regards,
Sam
