| 00:00.01 | Kevin2 | I looked at cegcc, and I agree they seem more advanced. However, according to their docs they require dlls to be installed on the target pda. I think this will be a problem for us, because it complicates the haret deployment. |
| 00:02.06 | psokolovsky | Kevin2, hm, and that extra DLL is not optional? then yes, wouldn't work for us ;-( |
| 00:04.49 | Kevin2 | The docs aren't specific on that point. If we can compile it statically that would be okay. However, the online docs seem to imply that it is a constraint. |
| 00:07.29 | psokolovsky | Kevin2, I'll check that. will look closer at VLC's stuff (still on todo) |

| 14:19.17 | pedro | Hi guys, I was reading the logs today, and I read someone meantioning cegcc. I am the cegcc maintainer. Maybe I could be of help? |
| 14:21.30 | psokolovsky | pedro: Hi! Good to see you here! |
| 14:21.41 | pedro | Well, I will just answer you questions :) Yes you can build apps without depending on the dll. just pass -static as usual. |
| 14:21.48 | psokolovsky | pedro: 1st question: have you moved to sf.net? |
| 14:21.58 | pedro | Yes. we have moved. |
| 14:22.12 | psokolovsky | pedro: ok, that was the main question (re: dll) |
| 14:22.27 | pedro | But I think you would be more interested in arm-wince-mingw32ce, instead of cegcc. |
| 14:22.38 | pedro | It is an official mingw port to CE. |
| 14:22.48 | pedro | s/official/unofficial/ :) |
| 14:22.54 | psokolovsky | pedro, would be nice if you marked berlios page as old snapshot, I posted about that to sf.net forum of cegcc |
| 14:23.08 | psokolovsky | pedro, where's that? |
| 14:23.22 | pedro | In trunk :) |
| 14:23.45 | psokolovsky | pedro, Cool! ;-) a release soon? |
| 14:23.55 | pedro | The homepage at cegcc.berlios.de already explains the move, maybe you meant something else? |
| 14:24.24 | pedro | Yep. Soon as every opensource project :) |
| 14:24.45 | psokolovsky | pedro, ok, I visited it some time ago, IIRC there was no mentioning then. |
| 14:25.25 | pedro | Ok, I will give a brief intro to the logs for everybody else. |
| 14:25.42 | psokolovsky | pedro, ok, nice! thanks for you responses - we'll go for it. And thanks for working on arm-wince-pe and alike targets! |
| 14:26.09 | pedro | Cegcc uses newlib to add a more complete runtime to Windows CE, since coredll is ... well... very limited. |
| 14:26.31 | pedro | Think of it as a cygwin for Windows CE, but not at all so complete. |
| 14:27.23 | pedro | Mingw32ce is supposed to use (almost) only the runtime support from coredll. It builds "native" apps. |
| 14:29.15 | pedro | I think the VLC toolchain would be comparable to our mingw32ce toolchain. |
| 14:30.34 | pedro | Except, we are activelly maintained. :) Also, the headers and mingw runtime is much tweaked to be a real replacement to the SDK headers, and to corelibc. |
| 14:34.57 | pedro | I also have an Universal, can't wait for you guys to make the phone work. |
| 14:35.03 | pedro | Well, I'll be going. Any questions, go to cegcc-devel at lists.sourceforge.net or pmail me at pedro_alves at portugalmail.pt. |
| 14:35.10 | pedro | Cheers. |
| 14:37.11 | psokolovsky | pedro, Thanks! |

| 16:06.42 | lamikr | pedro: Nice to hear from cegcc, I spend myself lot of time one year ago for trying to build good wince gcc, but had always problems... Is btw it possible to make UI apps with wince gcc? (Like add listbox with WindowCreateEx command, etc?) |
| 16:07.51 | pedro | Should be. If that doesn't work, it is bug that needs fixing. |
| 16:11.06 | pedro | From what I remember from the VLC toolchain, there was missing support for #pragma pack, so there could be problems in some w32api structures,preventing GUI apps, but that is now fixed in gcc from cegcc/mingw32ce. |
| 16:12.13 | pedro | Also some structures got fixed in w32api/include/*.h since they are different from the desktop versions of windows. Of course if you use SDK headers, you wont have this problem. |
| 16:12.15 | lamikr | nice, is there linux version available, or is it only for windows? |
| 16:12.46 | pedro | There is a prerelease binary version for linux available, but it is out-of-date already. |
| 16:13.01 | pedro | I develop on linux nowadays, do linux is pretty much supported. |
| 16:13.08 | pedro | "so linux" |
| 16:14.10 | pedro | Best for you to try would be to get the trunk version, and try the src/build-mingw32ce.sh script. |
| 16:14.19 | lamikr | nice... Do you know easy way to test the apps after build in Linux? Is the transfer to Wince only way or is there any emulator that could be run under Linux? |
| 16:15.01 | pedro | Not that I know. On windows I use the emulator from MSVC2005, on linux I tranfer to the device. |
| 16:15.13 | *** join/#htc-linux punkgeek (n=jeanseb@88.164.32.155) |
| 16:15.15 | pedro | but using gdb it is simple, it takes care of the uploading. |
| 16:16.54 | pedro | Oh and the MSFT's emulator doesnt run on wine... I tried. |
| 16:17.06 | lamikr | Really? Are you using wlan for that or is there method for establishing network connection from wince to Linux over usb cradle? |
| 16:17.20 | pedro | synce? |
| 16:17.29 | pedro | usb connection. |
| 16:17.43 | lamikr | Ok, I need to google the synce. |
| 16:17.45 | pedro | uses rapi. |
| 16:17.55 | pedro | http://synce.sourceforge.net/synce/ |
| 16:18.30 | pedro | well, rapi + sockets. Rapi is for the file uploading, but stricly necessary. |
| 16:18.45 | pedro | s/but/not/ ... |
| 16:20.18 | lamikr | I tried to use the eVC4 and smartphone 2003 emulator for developing the UI (lilo kind of boot selection) for h6300 linux loader in Windows, but I have had problems to get the eVC to connect to emulator for running the prebuild app. So it might be easiest just to jump back to Linux and work with synce & mingwce. |

| 16:40.35 | pedro | ok. just a hint. build-mingw32ce.sh will try to build c++ support. It wont work, because there is still a patch pending on the mailing list that hasnt been applied. |

| 16:46.44 | pedro | No such list, sorry. |
| 16:47.28 | cr2 | well, there are not that much gpl'd wince programs ;-) |
| 16:47.34 | pedro | Looks like roadmap is already ported to wince, right? So it should be much trouble porting it with mingw32ce. |
| 16:48.01 | cr2 | it is ported to wince and xp. |
| 16:48.02 | pedro | We are here to fix that :) |
| 16:48.23 | cr2 | but with m$ compilers. |
| 16:49.10 | cr2 | to be honest i'll prefer to have the native linux versions :) |
| 16:49.43 | pedro | Me too, but in the mean time, we have cegcc/mingw32ce. :) |
| 16:49.52 | cr2 | btw, what do you think about the wince dynamic loader like wine ? |
| 16:50.32 | pedro | Not sure what you mean? |
| 16:51.12 | cr2 | wine for wince. it will include the PE dynamic linker/loader and native coredll. |
| 16:51.42 | pedro | You mean a port of wine for arm? |
| 16:51.59 | lamikr | pedro: I think I will try to build also the c++ support. Do you url for the patch in mailing list? I think you do not mean support forum which seem quite empty? |
| 16:52.26 | pedro | yes, the mailing list, what a sec. |
| 16:53.32 | cr2 | it's not a complete port. imho it will be much easier to support wince apps. for several reasons. |

| 16:58.17 | cr2 | what is the best way to compile roadmap ? should i create a handcrafted Makefile ? |
| 16:58.45 | cr2 | roadmap is plain C afaik. |
| 16:58.48 | pedro | Does it build with autoconf? |
| 16:58.55 | cr2 | no. |
| 16:59.23 | cr2 | makefiles for linux, and some evc/msvc stuff for win* |
| 17:01.01 | pedro | Humm, since the linux version uses gtk, it would be probably easier to just make that handcrafted Makefile. |
| 17:01.42 | pedro | Just use something like $(TARGET)=arm-wince-mingw32ce $(CC)=$(TARGET)-gcc, etc. |
| 17:01.44 | cr2 | linux version exists for gtk,gtk2 and qt/qte. |
| 17:02.29 | cr2 | there is a port subtree for each gui target with its own build method. |
| 17:02.59 | pedro | oh, ok, I have a private port of qt4 to wince, using cegcc, I am in the progress of starting a mingw32ce port. But if it builds using native win32 for pocket pc, I would go that direction. |
| 17:03.22 | cr2 | but there is no automated script to convert ms*something to makefile. |

| 20:05.32 | pedro | lamikr: About not finding -lcoredll, are you using the build-cegcc.sh script? |
| 20:06.45 | lamikr | No, I was using build.sh. Should I call build-cegcc.sh instead directly? |
