This document describes the various ways in which you can build the MPS, its libraries, and the tests and tools that come with it.
You may be building the MPS for a number of different purposes.
Download the latest MPS Kit release from http://www.ravenbrook.com/project/mps/release/.
It is easy to compile the MPS. You can do it separately, or include the source in your own project’s build system. This section describes compilation in terms of command lines, but you can equally add the files to a project in an IDE.
The MPS also comes with Makefiles and IDE project files for building libraries, tools, and tests. See “Building the MPS for development”.
In the simplest case, you can compile the MPS to an object file with just:
cc -c mps.c (Unix/Mac OS X)
cl /c mps.c (Windows)
This will build a “hot” variety (for production) object file for use with mps.h. You can greatly improve performance by allowing global optimization, for example:
cc -O2 -c mps.c (Unix/Mac OS X)
cl /O2 /c mps.c (Windows)
You can get a “cool” variety MPS (with more internal checking, for debugging and development) with:
cc -g -DCONFIG_VAR_COOL -c mps.c (Unix/Mac OS X)
cl /Zi /DCONFIG_VAR_COOL /c mps.c (Windows)
If you are using your own object format, you will also get improved performance by allowing the compiler to do global optimizations between it and the MPS. So if your format implementation is in, say, myformat.c, then you could make a file mymps.c containing:
#include "mps.c"
#include "myformat.c"
then:
cc -O2 -c mymps.c (Unix/Mac OS X)
cl /O2 /c mymps.c (Windows)
This will get your format code inlined with the MPS garbage collector.
If you’re building the MPS for an environment without the standard C library, you can exclude the plinth component of the MPS with:
cc -DCONFIG_PLINTH_NONE -c mps.c
cl /Gs /DCONFIG_PLINTH_NONE /c mps.c
but you must then provide your own implementation of mpslib.h. You can base this on the ANSI plinth in mpsliban.c.
If you want to do anything beyond these simple cases, use the MPS build as described in the section “Building the MPS for development” below.
If you’re making modifications to the MPS itself, want to build MPS libraries for linking, or want to build MPS tests and tools, you should use the MPS build. This uses makefiles or Xcode projects. [Coming soon, Microsoft Visual Studio solutions.]
For Unix-like platforms you will need the GNU Make tool. Some platforms (such as Linux) have GNU Make as their default make tool. For others you will need to get and install it. (It’s available free from ftp://ftp.gnu.org/gnu/make/.) On FreeBSD this can be done as root with pkg_add -r gmake.
On Windows platforms the NMAKE tool is used. This comes with Microsoft Visual Studio C++ or the Microsoft Windows SDK.
On Mac OS X the MPS is built using Xcode, either by opening mps.xcodeproj with the Xcode app, or using the command-line “xcodebuild” tool, installed from Xcode → Preferences → Downloads → Components → Command Line Tools.
The MPS uses a six-character platform code to express a combination of operating system, CPU architecture, and compiler toolchain. Each six-character code breaks down into three pairs of characters, like this:
OSARCT
Where OS denotes the operating system, AR the CPU architecture, and CT the compiler toolchain. Here are the platforms that we have regular access to and on which the MPS works well:
Platform | OS | Architecture | Compiler | Makefile |
---|---|---|---|---|
fri3gc | FreeBSD | IA-32 | GCC | fri3gc.gmk |
fri6gc | FreeBSD | x86_64 | GCC | fri6gc.gmk |
lii3gc | Linux | IA-32 | GCC | lii3gc.gmk |
lii6gc | Linux | x86_64 | GCC | lii6gc.gmk |
xci3ll | Mac OS X | IA-32 | Clang | mps.xcodeproj |
xci6ll | Mac OS X | x86_64 | Clang | mps.xcodeproj |
xci3gc | Mac OS X | IA-32 | GCC (legacy) | xci3gc.gmk |
w3i3mv | Windows | IA-32 | Microsoft C | w3i3mv.nmk |
w3i6mv | Windows | x86_64 | Microsoft C | w3i6mv.nmk |
Historically, the MPS worked on a much wider variety of platforms, and still could: IRIX, OSF/1 (Tru64), Solaris, SunOS, Classic Mac OS; MIPS, PowerPC, ALPHA, SPARC v8, SPARC v9; Metrowerks Codewarrior, SunPro C, Digital C, EGCS. If you are interested in support on any of these platforms or any new platforms, please contact Ravenbrook at mps-questions@ravenbrook.com.
To build all MPS targets on Unix-like platforms, change to the code directory and run the command:
make -f <makefile>
where make is the command for GNU Make. (Sometimes this will be gmake or gnumake.)
To build just one target, run:
make -f <makefile> <target>
To build a restricted set of targets for just one variety, run:
make -f <makefile> 'VARIETY=<variety>' <target>
For example, to build just the “cool” variety of the amcss test on FreeBSD:
gmake -f fri3gc.gmk VARIETY=cool amcss
On Windows platforms you need to run the “Visual Studio Command Prompt” from the Start menu. Then run one of these commands:
nmake /f w3i3mv.nmk (32-bit)
nmake /f w3i6mv.nmk (64-bit)
You will need to switch your build environment between 32-bit and 64-bit using Microsoft’s setenv command, for example, setenv /x86 or setenv /x64.
To build just one target, run the command:
nmake /f w3i3mv.nmk <target>
On Mac OS X, you can build from the command line with:
xcodebuild
On most platforms, the output of the build goes to a directory named after the platform (e.g. fri3gc) so that you can share the source tree across platforms. On Mac OS X the output goes in a directory called xc. Building generates mps.a or mps.lib or equivalent, a library of object code which you can link with your application, subject to the MPS licensing conditions. It also generates a number of test programs, such as amcss (a stress test for the Automatic Mostly-Copying pool class) and tools such as mpseventcnv (for decoding telemetry logs).
Unix-like platforms can use the GNU Autoconf configure script in the root directory of the MPS Kit to generate a Makefile that can build and install the MPS. For example:
./configure --prefix=/opt/mps
make install
will install the MPS public headers in /opt/mps/include, the libraries in /opt/mps/lib etc.
There is currently no automatic way to “install” the MPS on Windows.
On any platform, you can install by copying the libraries built by the make to, for example, /usr/local/lib, and all the headers beginning with mps to /usr/local/include.
Note, however, that you may get better performance by using the method described in the section “Optimizing for your object format” above.
The MPS Kit can build a command-line program mpseventsql that loads a diagnostic stream of events into a SQLite3 database for processing. In order to build this program, you need to install the SQLite3 development resources.
On Mac OS X, SQLite3 is pre-installed, so this tool builds by default.
On Linux, you need to install the libsqlite3-dev package:
apt-get install libsqlite3-dev
and then re-run ./configure and make as described above.
On Windows, you should visit the SQLite Download Page and download the sqlite-amalgamation ZIP archive. (At time of writing this is the first download on the page.) When you unzip the archive, you’ll find it contains files named sqlite3.c and sqlite3.h. Copy these two files into the code directory in the MPS Kit. Then in the “Visual Studio Command Prompt”, visit the code directory and run the command:
nmake /f w3i3mv.nmk mpseventsql.exe
