Installation ------------ Run configure.bat to tell DevIL what external libraries you are using. Then go to Tools - Options - Directories to add in the include and lib directories for DevIL. Usage ----- In the Post-Build step, a Copy command used to copy the resultant dlls to the Windows\System directory. If your Windows System directory is not c:\Windows\System, edit the post-build step for all the DevIL* projects. When compiling a program that uses DevIL*, it must be configured to use the multithreaded dll version of the libc runtime. To do this, go to Project Settings - C/C++ tab - Change "Category" to 'Code Generation' - Change "Use run-time library" to 'Multithreaded DLL' or 'Debug Multithreaded DLL', based on whether the project you are build is release or debug, respectively. For more information, look at the tutorials.
