Compiling the Engine

I'm trying to recompile the engine and I'm getting the following errors. I changed my directories and linked to the right files

Code: Select all

CSurfaceLoaderJPG.o(.text+0x271):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_std_error'
CSurfaceLoaderJPG.o(.text+0x290):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_CreateDecompress'
CSurfaceLoaderJPG.o(.text+0x2eb):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_resync_to_restart'
CSurfaceLoaderJPG.o(.text+0x306):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_read_header'
CSurfaceLoaderJPG.o(.text+0x318):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_start_decompress'
CSurfaceLoaderJPG.o(.text+0x442):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_read_scanlines'
CSurfaceLoaderJPG.o(.text+0x47a):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_finish_decompress'
CSurfaceLoaderJPG.o(.text+0x48c):CSurfaceLoaderJPG.cpp: undefined reference to `jpeg_destroy_decompress'

Thanks in advance

IrrLicht uses JpegLib and some other supplimentary libraries. You'll probably have to have their headers and .lib/.a to be able to compile.

Do i need the libjped headers at all?

I believe you do, they provide jpeg loading support to the engine, which is pretty integral to the system.

on another note, the Irrlicht.dll that comes procompiled weighs in at 640k(or 604k, for 0.4). When I compile the MSVC project in the source directory, the dll bloats to over 2 megs, nearly 4 times that of the precompiled.

What's going on here?

You've got the active configuration set as Debug. If you change it to release, you'll see a drop in the DLL size. (It'll also be in the release folder

Well i'm not familiar with MSVC IDE yet but how about compiling the engine in release mode ?
Build->Set Active Configuration->Win32 Release

Oops DarkVisions was fast

also, I think if you're using DevCPP, its binaries are a little bit bigger.

for instance, I compiled my tiny tetris project in both MSVC and DevCpp:

"Release" mode in MSVC creates a binary of 56kb
"OptimizeMore" mode in DevCPP creates a binary of 152kb

If I use "BestOptimization" in DevCPP, the binary has problems.

supposedly MSVC creates the most optimized win32 binaries, and why not? the same company made both the compiler and the OS

off-topic: who makes devcpp?
