Directory structure
|
||
|
|
===================
|
||
|
|
Although I have made every effort not to use absolute paths, I have only tested building
|
||
|
|
with my own directory structure and it looks like this:
|
||
|
|
|
||
|
|
c:\project\llvm ; Main project directory
|
||
|
|
c:\project\llvm\win32 ; win32 project
|
||
|
|
c:\project\llvm\win32\tools ; flex, bison and sed live here
|
||
|
|
c:\project\llvm\win32\share ; flex, bison and sed support files
|
||
|
|
|
||
|
|
Requirements
|
||
|
|
============
|
||
|
|
|
||
|
|
You need flex, sed and bison - I'm using the GnuWin32 versions of these tools which can be obtained from
|
||
|
|
|
||
|
|
http://gnuwin32.sourceforge.net/
|
||
|
|
|
||
|
|
Limitations
|
||
|
|
============
|
||
|
|
|
||
|
|
At the moment only the core LLVM libraries and the tablegen executable are built. If anyone has time to
|
||
|
|
port the rest of the LLVM tools it would be great...
|
||
|
|
|
||
|
|
Other notes
|
||
|
|
===========
|
||
|
|
|
||
|
|
When linking with your own application it is of the utmost importance that you use the same runtime
|
||
|
|
libraries in compiling LLVM as in your own project. Otherwise you will get a lot of errors. To change this,
|
||
|
|
just mark all the projects except the Config project (since it doesn't use the C compiler) in the
|
||
|
|
solution explorer, select properties - then go to the C/C++ options and the Code Generation sub option page.
|
||
|
|
In the Runtime Library (6th from the top) select the appropriate version. Then change the active
|
||
|
|
configuration to Release (in the top left corner of the properties window) and select the appropriate
|
||
|
|
runtime library for the release version.
|
||
|
|
|
||
|
|
When linking with your applications, you need to force a symbol reference to bring in the x86 backend.
|
||
|
|
Open the properties for your main project and select the Linker options - under the Input options there
|
||
|
|
is a Force Symbol References field where you need to enter _X86TargetMachineModule. If anyone has a better
|
||
|
|
suggestion for how to trick the linker into always pulling in these objects, I'd be grateful...
