remove -fno-rtti from makefile

forgot to mention i tried that here is the output from removing that its in all the pspsdk samples for some reason and i dont even know what it does

Did you link your boost library? (dunno mayby -lboost)

boost4PSP now includes boost::filesystem !? I asked if boost::filesystemcan be included a long time ago. Up to now, I thought it was an abandoned project.

well it wont compile i didnt see libboost_filesystem.a in the install either so its headers are included but the lib isnt

Hi,

RTTI stands for "RunTime Type Information". It's a mechanism that allows a program to get informations about the type of an object at run-time. You use RTTI when you use dynamic_cast or typeid.

-fno-rtti means "don't use RTTI", hence the "cannot use typeid with -fno-rtti" error message. This option is there for a reason: RTTI is not available on PSP (I guess that's what the "undefined reference" messages try to tell you). So basically, you won't compile a library that uses it.

Nope, still not included. I didn't have the time to include others libraries since then, being busy on other open source projects.

But even with time, I'm afraid libraries like Boost.FileSystem, Boost.Thread, etc that are very platform-dependent couldn't be easily integrated. The issue here with RTTI tends to confirm this.

i can compile with -frtti but not sure how to do it the compiling part
