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
o "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
o 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.
o 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:
o Microsoft Embedded Visual Tools
o Microsoft Visual C++
o Rainer Keuchel's celib-sources
o Rainer Keuchel's console-sources
Needed source files can be downloaded at
http://www.rainer-keuchel.de/wince/dirlist.html
<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:
o go to "./win32" subdirectory
o edit file "./win32/ce-helpers/compile.bat"
o run
compile.bat
o 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

Perl Programmers Reference Guide PERLCE(1)
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
perl v5.12.5 Last change: 2012-11-03 3
Perl Programmers Reference Guide PERLCE(1)
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::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.
