Almost everything causes a multiple definition error.

[Midnightas]

I simply copied the source of Bullet onto my project that is to be built with `-m32` but when it goes into the object file linking stage pretty much everything causes a multiple definition error.

Here's just around 5-10% of it.

Code: Select all

I made sure, and no object file was being linked twice.

Immediately after posting this I realized the error. The "*All.cpp" files were including other .cpp files. Simply delete those.
