[edit] Building Blender with C++ Express and Scons on Windows XP/Vista
Install the following Applications / Libraries
1. MS C++ Express
2. Python 2.5
3. Scons
4. Windows SDK for your version of Windows
5. DirectX SDK
6. TortoiseSVN
7. Download /trunk/lib/windows from SVN (contains all the libs for windows)
8. Download and copy the Quicktime Dev Kit to lib/windows/QTDEVWIN
In blender/config/win32-vc-config.py
set openexr path to lib_vs2005
In windows Environment Variables
Add the following paths (replace with your installation paths if different)
PATH add c:\python25
INCLUDE add C:\Program Files\Microsoft Visual Studio 8\VC\include
INCLUDE add C:\Program Files\Microsoft SDKs\Windows\v6.0\Include
LIB add c:\DX90SDK\lib;
LIB add C:\Program Files\Microsoft SDKs\Windows\v6.0\lib
Download SVN Trunk
run scons from the Blender Folder.
For ease, make this batch file This will update your SVN, and rebuild your checkout.
c: cd\blendersvn "c:\Program Files\TortoiseSVN\bin\TortoiseProc" /command:update /path:c:\blendersvn\blender\ /closeonend:1 /notempfile cd blender call scons
If you download multiple branches, change the build folder in config/win32-vc-config.py, but leave the install folder normal. Then in the /Sconstruct file at around line 317 there is a reference to env.BlenderProg(B.root_build_dir, "blender" change the "blender" to another name and that is what that branches exe will be called.

[edit] Various other build and compiler specific guides
These guides are listed here in the hope that you find them useful. The usual disclaimers apply, the guides are not maintained by the blender documentation team.

For Windows using MinGW and SCons
[edit] Project Files
Now with the introduction of CMake, Visual Studio, and XCode project files are probably not going to be directly maintained. Project files support tends to lag behind the other build systems, unless you must use these hand-maintained project files, use one of the other build systems. Otherwise, you should be using CMake to generate project files.
[edit] VS Build Files
bf-blender/blender/projectfiles (for MSVC6) bf-blender/blender/projectfiles_v7 bf-blender/blender/extern/make bf-blender/blender/intern/make
[edit] Where VS Puts things
bf-blender/build bf-blender/blender/bin
[edit] XCode Project Files

[edit] Structure of the bf-blender code tree
This is a folder by folder explanation of the bf-blender source code tree. This should help you answer questions such as "is this the right place to put includes for internal use?"
[edit] File Types in the Source Tree
There are all kinds of various files inside of the source code. Here is a list of the major types of files you will be dealing with and how to identify what they are.
| -- Filename -- | -- File Type -- |
|---|---|
| blender | Unix has no extension for binary file types |
| .exe | Windows Executable |
| .app | OSX Executable |
[edit] Compiler Basics
There are a few basic areas people tend to have issues with. A quick rundown of them and how to fix them follow. The following is based on GCC, other compilers will work similarly but the details will differ. The links have carefully crafted examples of the issues and their solutions for both Makefiles and SCons.
- Unable to find a header (.h)
Use -I(dir) Example: -I/usr/local/include
- Unable to find shared library when linking (.so, .dll)
Use -L(dir) -l(lib) Example: -L/usr/local/lib -lm
- Unable to find static library when linking (.a)
Use full path to library Example: /usr/local/lib/libjpeg.a
- Unable to find shared library when running app
Use -L(dir) -Wl,-rpath -Wl,(dir) -l(lib) Example: -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -ljpeg On solaris need to use -L(dir) -R(dir) -l(lib) Example: -L/usr/local/lib -R/usr/local/lib -ljpeg
- Undefined symbol: blahhhh
Need to include extra library (static or dynamic)
[edit] Troubleshooting
[edit] Error: png.h: No such file or directory
Possible Problems:
[edit] Library not installed
Determine library (websearch, educated guess) Install the library. Note: on linux its common that the library may be installed but the "dev" package for the library is not installed. In that case you need to install it also.
[edit] Blender thinks library is in a different place
Makefiles: add to user-def.mk export NAN_PNG=/usr SCons: add to user-config.py BF_PNG=/usr
Some headers are in different locations depending on distribution. Example: /usr/local/include/Freetype vs /usr/local/freetype/include
To fix this you need to dive down deeper into the build system.
Makefiles: You probably need to find specific Makefiles with NAN_FREETYPE
and modify them.
grep NAN_FREETYPE `find . -name Makefile -print`
Scons: You will need to edit user-config.py and add/modify
BF_FREETYPE, BF_FREETYPE_INC, BF_FREETYPE_LIB (possibly more)
[edit] Error: No Rule to make target '/blender/lib/libpng.a' needed by /blender/obj/.........
Possible Problems:
[edit] Library not installed
(See above section in missing .h)
[edit] Blender looking for library in wrong location
(see above section in missing .h)
[edit] You may have a dynamic lib installed and its expecting a static lib
Install the static lib as well, or modify compile options to use dynamic lib instead of static lib.
[edit] Error: cannot find -lpng
Possible Problems:
[edit] Library not installed
(See above section in missing .h)
[edit] Blender looking for library in wrong location
(see above section in missing .h)
[edit] You may have a static lib installed and its expecting a dynamic lib
Install the dynamic lib as well, or modify compile options to use static lib instead of dynamic lib.
[edit] Error: Undefined symbol _vorbis
[edit] You have an out of date library
First thing to try is do a cvs update, both blender and your lib directory if you are using a lib directory. Then do a clean build.
For Makefiles rm -rf obj/(platform) You will need to look at your obj dir
to figure out what (platform should be)
For Scons do scons clean.
[edit] You are using a library that has extra dependancies blender does not know about
In this case you will need to figure them out and then add the extra dependancies.

Building Blender With Make using Cygwin
Compiling with VC7 - Note that the project files are now vc7.1.
Compiling Blender on Ubuntu Feisty Fawn
If there are problems compiling, feel free to join #blendercoders on irc.freenode.net for assistance. If someone can help, it's generally standard procedure to switch over to #blendercompilers, so people arn't conducting complex debugging in #blendercoders itself. Please note: use an online paste bin (such as pastebin.com or Rafb paste) for large error messages, don't paste them into irc!
