This is what you need to do to install uLPC:
1) Run ./configure, this is a sh script that will generate machine.h and
Makefile from machine.h.in and Makefile.in, use --prefix=/foo/bar
if you want to install ulpc in /foo/bar, default is /usr/local.
You might have to set the environment variables C_INCLUDE_PATH and
LD_LIBRARY_PATH to enable the configure script to find gdbm and gmp.
If the configure script does not find those libraries those modules
will not be available.
2) edit config.h and Makefile to suit your purposes.
I've tried to make it so that you don't have to change config.h or
Makefile very much. If you need to do what you consider 'unnessecary
changes' then mail me and I'll try to fit it into configure.
If possible, use gnu make, gcc, gnu sed and bison.
3) Run make.
4) optionally, run 'make verify' to check that the compiled driver works
as it should (might be a good idea) This will take a little time and use
quite a lot of memory, because the testprogram is quite large. If everything
works out fine no extra messages are written.
5) If you want to install ulpc, write 'make install'
6) Optionally do 'make html_docs' to create a directory called docs which
will contain the uLPC documentation in html. This directory can then
be copied to anywhere you want.
What to do when it doesn't work:
1) Try again.
2) Your sh might be too buggy to run ./configure. (This is the case on A/UX)
Try using bash, zsh or possibly ksh. To use bash, first run /bin/sh and
$ export CONFIG_SHELL
$ $CONFIG_SHELL ./configure
3) ./configure relies heavily on sed, if you have several sed in your path
try another sed. (preferably gnu sed)
4) configure might have done something wrong, check machine.h and report
any errors back to me.
5) Try a different compiler, malloc, compiler-compiler and/or make.
(if you have any other)
6) On Linux Slackware machines (older than slackware 3.0), uLPC sometimes
fails to find -lm, this is because of a bug in /usr/lib/libm.sa
(or possibly libg.a) in slackware.
Compile with 'make EXTRALIBS="-lc -lm"' to get around this bug.
If you find a bug in the interpreter, the first thing to do is to make sure
the interpreter is compiled with DEBUG defined. If not recompile with DEBUG
and see if you get another error. When you've done this, please report the
bug to email@example.com and include as much as you can muster of the
o The version of the driver. (can be found in lib/simulate.lpc)
o What kind of system hardware/software you use (OS, compiler, etc.)
o the piece of code that crashes or bugs.
(preferably in a very small lpc-script with the bug isolated)
Please send a complete running example of something that makes the
o a description of what it is that bugs and when.
o if you know how then also give me a backtrace and dump of vital variables
at the point of crash.
o or, if you found the error and corrected it, just send me the bugfix along
with a description of what you did and why.
