Hi, I’m spent countless time in searching working ruby port on Windows Mobile. I’m not a fan of this OS, but already have device with it and still want to try programming in ruby on it. Google kicked me to: 1. Howto compile and binaries ruby 1.8.x with Microsoft Visual Embedded C++ ( [ruby-mswince](http://uema2.s8.xrea.com/ruby-mswince/) ). This works fine, but first of all it has Windows Mobile restriction on relative paths (ex. requiring 'lib/some.rb" - fails) and in addition it is 1.8 - not 1.9. There is no chance to use it as full value port, especially with rubygems. 2. Success story of compiling ruby 1.8 with CeGCC cross compile toolchain ( [http://cegcc.sourceforge.net/](http://cegcc.sourceforge.net/) ). Here is the topic of John Snowdon aka smed: [Ruby on WinCE / cegcc - Ruby - Ruby-Forum](http://www.ruby-forum.com/topic/143475) . He successfully compiled ruby 1.8 even with rubygems (!). But for my sorry I can’t reproduce his success and his blog with binaries is down too ( [http://www.target-earth.net/gadgets/code/rubyce.html](http://www.target-earth.net/gadgets/code/rubyce.html) ). In addition it is 1.8 branch and it will be more likely to use 1.9.x 😛 So, i’m trying to compile ruby 1.9.1 p429 with CeGCC 0.59.1 under Ubuntu 10.04. First trouble that I get - is that confuigure script can’t verify setpgrp() while cross-compiling. I solve it by adding “ac\_cv\_func\_setpgrp\_void=yes” to args. Next trouble was that configure script cannot detect pthread\_kill function in any header, so it suggest not to use native threads, but in 1.9.x native threads - are mandatory. Some search kick me to mail list with howto compile pthreads-win32 ( [The Pthreads-win32 Archives](http://sourceware.org/ml/pthreads-win32/) ) with mingw32ce (mingw32 part of cegcc). I reproduced his success and now i have .dll, .a and headers. First my question is - can I it ( library compiled with mingw32ce) in compiling with cegcc? I’m novice in cross compiling and it would be greate if someone can hint how do I use it in compilng: some extra environment variable, makefile edits or maybe i can add some args to configure script? I think i choose dirty incorrect way, trying to hack makefile and sources in order to bypass errors. I added “-I/path/to/pthreads” to optflags variable in Makefile. I’m compiling with this environment: ruby sources is in: /var/tmp/ruby-1.9.1-p429 pthreads-win32 sources, library file(.a) and its dll in: /var/tmp/pthreads-w32-2-8-0-release cegcc is in: /opt/cegcc mingw32ce is in: /opt/mingw32ce this is my PATH env variable: /opt/mingw32ce/bin:/opt/cegcc/bin:/opt/cegcc/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/android-sdk-linux\_86/tools and this is line with which i’m compiling: CC=arm-cegcc-gcc CPP=arm-cegcc-cpp AR=arm-cegcc-ar AS=arm-cegcc-as OBJCOPY=arm-cegcc-objcopy OBJDUMP=arm-cegcc-objdump RANLIB=arm-cegcc-ranlib LIBS=“-I/var/tmp/pthreads-w32-2-8-0-release -I/opt/cegcc/include -I/opt/cegcc/arm-cegcc/include” LDFLAGS=“-L/var/tmp/pthreads-w32-2-8-0-release -L/opt/cegcc/lib -L/opt/cegcc/arm-cegcc/lib” ./configure --host=arm-wince –prefix=/WinCE/built --enable-shared ac\_cv\_func\_setpgrp\_void=yes –enable-pthread=pthread and this is my output: axe1@axe1-desktop:/var/tmp/ruby-1.9.1-p429$ make GNUmakefile:43: target `ruby.rc’ given more than once in the same rule. include-dir . --include-dir . --include-dir ./win32 ruby.rc ruby.res.o make: include-dir: Command not found make: [ruby.res.o] Error 127 (ignored) arm-cegcc-gcc -O2 -I/var/tmp/pthreads-w32-2-8-0-release -g -Wall -Wno-parentheses -I. -I.ext/include/arm-wince -I./include -I. -DRUBY\_EXPORT -o io.o -c io.c io.c: In function ‘rb\_io\_close\_read’: io.c:3369: warning: implicit declaration of function ‘rb\_w32\_is\_socket’ io.c: In function ‘pipe\_open’: io.c:4643: warning: implicit declaration of function ‘rb\_w32\_aspawn’ io.c:4643: error: ‘P\_NOWAIT’ undeclared (first use in this function) io.c:4643: error: (Each undeclared identifier is reported only once io.c:4643: error: for each function it appears in.) io.c:4644: warning: implicit declaration of function ‘rb\_w32\_spawn’ io.c: In function ‘io\_cntl’: io.c:6709: warning: implicit declaration of function ‘ioctl’ io.c: In function ‘maygvl\_copy\_stream\_wait\_read’: io.c:7351: warning: implicit declaration of function ‘select’ make: \*\*\* [io.o] Error 1 can anybody kick me to right way on solving this? I couldn’t understand why ruby uses some _w32_ function when i’m compiling with posix compilant toolchain… P.S. Sorry for my bad english - my native language is russian. ---

I think I remember wince being removed recently from 1.9 branch (no maintainer, little interest), so grabbing a build _before_ that might work better. But I don’t remember exactly. ---

I’m on Ubuntu linux if you mean my OS. And as far as i know configure script should think i compile it for linux, cause cegcc emulates POSIX API and is designed to cross-compile linux apps to windows mobile. So i couldn’t understand why it tries some _w32_ functions… > The rubyinstaller list might be helpful, as well. > [http://rubyinstaller.org/](http://rubyinstaller.org/) I’ll post my message there if I wouldn’t get answers here, but… they use MinGW32 environment to compile ruby for Win32… This isn’t near my goal I think, isn’t it? > I think I remember wince being removed recently from 1.9 branch (no > maintainer, little interest), so grabbing a build _before_ that might > work better. But I don’t remember exactly. It’s true. Sorry I forgot to say that I already tries to compile latest ruby 1.9.x branch without removed WinCE scripts (it’s 1.9.0.5, [GitHub - ruby/ruby at v1\_9\_0\_5](http://github.com/ruby/ruby/tree/v1_9_0_5)). First of all it seems that WinCE folder there is unchanged since 1.8.x branch and it doesn’t compiles. In addition it uses Microsoft Embedded Visual C++ compiler to build. And at [ruby-mswince](http://uema2.s8.xrea.com/ruby-mswince) is 1.8.x branch compiled with official support. ---

Yeah but they may have some expertise. Unfortunately I don’t really 🙂 -r
