NAME
perlce - Perl for WinCE
Building Perl for WinCE
DESCRIPTION
This file gives the instructions for building Perl5.8 and above for WinCE. Please read and understand
the terms under which this software is distributed.
General explanations on cross-compiling WinCE
miniperl
is built. This is a single executable (without DLL), intended to run on Win32, and it
will facilitate remaining build process; all binaries built after it are foreign and should not run
locally.
miniperl
is built using
./win32/Makefile;
this is part of normal build process invoked as
dependency from wince/Makefile.ce
After
miniperl
is built,
configpm
is invoked to create right
Config.pm
in right place and its
corresponding Cross.pm.
Unlike Win32 build, miniperl will not have
Config.pm
of host within reach; it rather will use
Config.pm
from within cross-compilation directories.
File
Cross.pm
is dead simple: for given cross-architecture places in @INC a path where perl
modules are, and right
Config.pm
in that place.
That said,
miniperl -Ilib -MConfig -we 1
should report an error, because it can not
find
Config.pm.
If it does not give an error -- wrong
Config.pm
is substituted, and resulting
binaries will be a mess.
miniperl -MCross -MConfig -we 1
should run okay, and it will provide right
Config.pm
for further compilations.
During extensions build phase, a script
./win32/buldext.pl
is invoked, which in turn
steps in
./ext
subdirectories and performs a build of each extension in turn.
All invokes of
Makefile.PL
are provided with
-MCross
so to enable cross- compile.
BUILD
This section describes the steps to be performed to build PerlCE. You may find additional information
about building perl for WinCE at
http://perlce.sourceforge.net
and some pre-built binaries.
Tools & SDK
For compiling, you need following:
* Microsoft Embedded Visual Tools
* Microsoft Visual C++
* Rainer Keuchel's celib-sources
* Rainer Keuchel's console-sources
Needed source files can be downloaded at
http://www.rainer-keuchel.de/wince/dirlist.html
Make
Normally you only need to edit
./win32/ce-helpers/compile.bat
to reflect your system and
run it.
File
./win32/ce-helpers/compile.bat
is actually a wrapper to call
nmake -f makefile.ce
with appropriate parameters and it accepts extra parameters and forwards them to
nmake
command
as additional arguments. You should pass target this way.
To prepare distribution you need to do following:
http://perldoc.perl.org
Page 1
Perl version 5.10.0 documentation - perlce
* go to
./win32
subdirectory
* edit file
./win32/ce-helpers/compile.bat
* run compile.bat
* run compile.bat dist
Makefile.ce
has
CROSS_NAME
macro, and it is used further to refer to your cross-compilation
scheme. You could assign a name to it, but this is not necessary, because by default it is assigned
after your machine configuration name, such as "wince-sh3-hpc-wce211", and this is enough to
distinguish different builds at the same time. This option could be handy for several different builds on
same platform to perform, say, threaded build. In a following example we assume that all required
environment variables are set properly for C cross-compiler (a special *.bat file could fit perfectly to
this purpose) and your
compile.bat
has proper "MACHINE" parameter set, to, say,
wince-mips-pocket-wce300.
compile.bat
compile.bat dist
compile.bat CROSS_NAME=mips-wce300-thr "USE_ITHREADS=define"
"USE_IMP_SYS=define" "USE_MULTI=define"
compile.bat CROSS_NAME=mips-wce300-thr "USE_ITHREADS=define"
"USE_IMP_SYS=define" "USE_MULTI=define" dist
If all goes okay and no errors during a build, you'll get two independent distributions:
wince-mips-pocket-wce300
and
mips-wce300-thr.
Target
dist
prepares distribution file set. Target
zipdist
performs same as
dist
but additionally
compresses distribution files into zip archive.
NOTE: during a build there could be created a number (or one) of
Config.pm
for cross-compilation
("foreign"
Config.pm)
and those are hidden inside
../xlib/$(CROSS_NAME)
with other auxilary
files, but, and this is important to note, there should be
no
Config.pm
for host miniperl. If you'll get
an error that perl could not find Config.pm somewhere in building process this means something went
wrong. Most probably you forgot to specify a cross-compilation when invoking miniperl.exe to
Makefile.PL When building an extension for cross-compilation your command line should look like
..\miniperl.exe -I..\lib -MCross=mips-wce300-thr Makefile.PL
or just
..\miniperl.exe -I..\lib -MCross Makefile.PL
to refer a cross-compilation that was created last time.
All questions related to building for WinCE devices could be asked in
perlce-user@lists.sourceforge.net
mailing list.
Using Perl on WinCE
DESCRIPTION
PerlCE is currently linked with a simple console window, so it also works on non-hpc devices.
The simple stdio implementation creates the files
stdin.txt, stdout.txt
and
stderr.txt,
so
you might examine them if your console has only a liminted number of cols.
When exitcode is non-zero, a message box appears, otherwise the console closes, so you might have
to catch an exit with status 0 in your program to see any output.
stdout/stderr now go into the files
/perl-stdout.txt
and
/perl-stderr.txt.

PerlIDE is handy to deal with perlce.
LIMITATIONS
No fork(), pipe(), popen() etc.
ENVIRONMENT
All environment vars must be stored in HKLM\Environment as strings. They are read at process
startup.
PERL5LIB
Usual perl lib path (semi-list).
PATH
Semi-list for executables.
TMP
- Tempdir.
UNIXROOTPATH
- Root for accessing some special files, i.e.
/dev/null, /etc/services.
ROWS/COLS
- Rows/cols for console.
HOME
- Home directory.
CONSOLEFONTSIZE
- Size for console font.
You can set these with cereg.exe, a (remote) registry editor or via the PerlIDE.
REGISTRY
To start perl by clicking on a perl source file, you have to make the according entries in HKCR (see
ce-helpers/wince-reg.bat).
cereg.exe (which must be executed on a desktop pc with
ActiveSync) is reported not to work on some devices. You have to create the registry entries by hand
using a registry editor.
XS
The following Win32-Methods are built-in:
newXS("Win32::GetCwd", w32_GetCwd, file);
newXS("Win32::SetCwd", w32_SetCwd, file);
newXS("Win32::GetTickCount", w32_GetTickCount, file);
newXS("Win32::GetOSVersion", w32_GetOSVersion, file);
newXS("Win32::IsWinNT", w32_IsWinNT, file);
newXS("Win32::IsWin95", w32_IsWin95, file);
newXS("Win32::IsWinCE", w32_IsWinCE, file);
newXS("Win32::CopyFile", w32_CopyFile, file);
newXS("Win32::Sleep", w32_Sleep, file);
newXS("Win32::MessageBox", w32_MessageBox, file);
newXS("Win32::GetPowerStatus", w32_GetPowerStatus, file);
newXS("Win32::GetOemInfo", w32_GetOemInfo, file);
newXS("Win32::ShellEx", w32_ShellEx, file);

BUGS
Opening files for read-write is currently not supported if they use stdio (normal perl file handles).
If you find bugs or if it does not work at all on your device, send mail to the address below. Please
report the details of your device (processor, ceversion, devicetype (hpc/palm/pocket)) and the date of
the downloaded files.
INSTALLATION
Currently installation instructions are at
http://perlce.sourceforge.net/.
After installation & testing processes will stabilize, information will be more precise.
ACKNOWLEDGEMENTS
The port for Win32 was used as a reference.
History of WinCE port
5.6.0
Initial port of perl to WinCE. It was performed in separate directory named
wince.
This port
was based on contents of
./win32
directory.
miniperl
was not built, user must have HOST
perl and properly edit
makefile.ce
to reflect this.
5.8.0
wince port was kept in the same
./wince
directory, and
wince/Makefile.ce
was used to
invoke native compiler to create HOST miniperl, which then facilitates cross-compiling
process. Extension building support was added.
5.9.4
Two directories
./win32
and
./wince
were merged, so perlce build process comes in
./win32
directory.
AUTHORS
Rainer Keuchel <coyxc@rainer-keuchel.de>
provided initial port of Perl, which appears to be most essential work, as it was a breakthrough
on having Perl ported at all. Many thanks and obligations to Rainer!
Vadim Konovalov
made further support of WinCE port.
