Compiling the MSP source code

Building the base source tree

If you'd like to make any changes to the MSP software, or would like to build new applications on top of the existing MSP software, you'll first need to compile the MSP source tree. To do so:

1. Check out the MSP source code from the CSE subversion repository:

   svn co svn+ssh://<username>@coco.cs.washington.edu/projects/ubicomp/uwar/subversion/msp

   . TODO: Move this to a public repository.
2. Switch to the source directory:

   cd msp/src

3. Run the configure script. If building the MSP software for a native system, just run:

   ./configure

   If building the MSP software for the MSP, execute:

   CROSS_COMPILE=<path to cross-compiler>/bin/arm-linux- ./configure

   On CSE machines, this would be:

   CROSS_COMPILE=/projects/ubicomp/uwar/arm-linux/3.4.3_binutils/bin/arm-linux- ./configure

4. Execute make:

   make

Extending the source code

If you'd like to develop your own applications, there are a few things you need to do to integrate it with the MSP build system:

1. Create a directory in src for your project.
2. In that directory, create a Makefile. Use this template:

   include ../Makefile.conf
   
   MODULE_NAME = "<short module name>"
   MODULE_COMMENT = "<module description>"
   
   CFLAGS +=
   IFLAGS +=
   LFLAGS +=  -lglobal -lipc <any other libs you need>
   
   SOURCES = <a list of source files, seperated by spaces>
   
   PUBLIC_INCLUDES = <any header files to make available to other apps, seperated by spaces>
   PUBLIC_LIBRARIES = <any library files to make available to other apps, seperated by spaces>
   PUBLIC_BINARIES = <any binaries to copy to the bin directory>
   MAN_PAGES =
   
   TARGETS = <a list of the binaries and potentially libraries to build, seperated by spaces>
   
   target-1:               <source objects, seperated by spaces>
   
   target-2:               <source objects, seperated by spaces>
   
   # rules
   
   include ../Makefile.rules
   

   Here's an example Makefile from the camera server:

   include ../Makefile.conf
   MODULE_NAME = "Camera"
   MODULE_COMMENT = "Camera Server"
   CFLAGS +=
   IFLAGS += -I../../extern/ipp/5.0/pca_wmmx/include/
   LFLAGS += -L../../extern/ipp/5.0/pca_wmmx/lib/pvkit -l ippIP_WMMX50LNX_r -l ippJP_WMMX50LNX_r -l ippAC_WMMX50LNX_r -l ippSP_WMMX50LNX_r -lglobal
   SOURCES = cam-server.c ippimem.c
   PUBLIC_INCLUDES = camera_interface.h
   PUBLIC_LIBRARIES = libcamera_interface.a
   PUBLIC_BINARIES =
   TARGETS = libcamera_interface.a cam-server
   PUBLIC_LIBRARIES_SO =
   libcamera_interface.a:  camera_interface.o
   cam-server:             cam-server.o ippimem.o crc32.o
   
    rules
   include ../Makefile.rules
   
   

3. Add the directory name to the list of PACKAGES in the main Makefile:

   PACKAGES = ipc global fileio activity-inference msb imu logger proccontrol system-tools gps examples \
              lsb new-gps camera gps-debug sb-update <new directory>
