Depending on how your kernel is configured this may work.

I came accross something that might help people "fix" the problem with iG3 crashing on them.

In /etc/profile add the line ulimit -n 655350 at the end.

This will increase the number of open files allowed (that is if the kernel allows it). At the rate of consumption of about 5 files per second you should be good for about 36 hours of recording data before it crashes

Edit: Well, it ran for 8 hours before crashing. It crashed with another error "Xlib: resource ID allocation space exhausted!"

I'm no expert and I'm sure this isn't exactly the best thing to do, and I'm not sure how it is going to affect the system long term, but it will at least keep ig3 running for a while.

Yes normal wine, but i think i had to put some DLLs in the wine directory.

I can post later which DLLs i have in my wine-directory

In case anyone else was having problems with iGuidance 3 working , I finaly got it working.

I used crossover office 6 beta(this is the latest available at this time). This fixed the problem with running out of filehandles. I then had a problem where it crashed with an xlib error. This was fixed when I put Load "extmod" in my xorg.conf file.

I don't know if anyone cares. I just thought I would share so anyone that was having the same problem would know the solution.

I will probably have to buy crossover office in the next few weeks when the beta times out but it is a small price to pay.

A side note is that graphics flicker twice whenever you pull up a menu. Also, some menus aren't perfectly displayed, but they seem to function correctly.

I'm starting to think just another nanoITX or something running just iG3 and a video switch will be easier all of which I already have, except iG3 itself.

I care, and thank you.

I'm slightly stuck with my TinyGentoo environment in getting a minimal xorg working. My kernel + initrd with a full busybox, screen, dropbear (ssh server) is 3.7MB compressed. If I emerge xorg into the initrd, it becomes 142MB or so...

This is good info to have when I do get to the point where I'm installing crossover and IG3 onto my working Xorg based compact flash install of gentoo.

Hi guys,
Just wanted to drop a note - I am currently working on "Version 2.0" of my CarPC and came across this post. This is VERY exciting to me, So I just ordered a copy of iguidance v3. I am doing a complete redesign of my interface (and documenting it this time). Hopefully, iguidance+crossover office will be a suitable GPS solution.

P.S.: here is a teaser for my new interface:

timekiller

Got iGuidance last night, installed under crossover office. Let me just say WOW.

This has exceeded my expectations by a long shot. And it works perfectly in "Car PC" mode with my lilliput touchscreen. This is basically a drop in working gps solution for my linux carpc. I couldn't be happier!

Although, on the down side, my gps dongle died last night (unrelated to installing the software). I order a new one, but have to wait to REALLY play with the software.

Currently I am stress testing it by using demo mode to play a route between my house in NJ and Caesar's Palace in Las Vegas I figure if it is going to crash at all, this will show me.

intuitionsys

This is great news! Maybe I won't go the two computers route afterall. Keep us updated on your results, especially after you get your new dongle.

demo route has been running for 6 hours now - i have been constantly zooming in and out, looking up POIs, clicking around the screen, basically TRYING to break it. No issues so far, and i'm about 30 hours away from Vegas (virtually)

Just got an email that the dongle shipped, Hopefully I can put it all back in my car this weekend.

Geese

That's awesome. Tell me (us) more about your system, distro, and any specific tweaks you've done.

Thanks!

Ok,
I am ready for the full report:

My hardware:
Via Epia M10000 Mobo
512MB Ram
Lilliput 7" touchscreen
BU-353 GPS Receiver
(other misc.)

Software:
Gentoo 2006.1 x86
OpenChrome video drivers
MythTV .20
Crossover Office 6 beta 2
iGuidance v3
(other misc.)

I have tested iGuidance/Crossover Office/Gentoo on both my CarPC and my laptop (AMD Athlon(tm) 64 Processor 3400+). On my laptop, I see no problems whatsoever. program is extremely responsive, and basically runs like a native linux app. On my CarPC I have noticed two (very) minor issues. First, there is the occasional video "glitch" nothing major, but every once in a while the non-road portions of the map will display the wrong color, like a band of green where it should be grey. It is not often, in fact, I tried to get a picture of it, but could not get it to happen again. I assume this glitch is because of the video driver (the via hardware acceleration and openchrome drivers are not 100% yet). The other glitch I noticed is the voice prompt stutters a little on the car pc. This is prolly because the cpu is only 1Ghz.

Again, on my laptop, none of the glitches exist.

I snapped some pictures of the software in use, you can see them at https://www.timekiller.org/carpc/images/pics/

So, here is a quick rundown of how I installed this:

On my Laptop (I installed everything here first for testing, and because I do not have a dvd drive on my car pc):
1) Compile kernel with USB serial driver pl2303 (for BU-353 GPS)
2) Install cxoffice6 beta. (of course when the official release is available I will be purchasing it)
3) Install iGuidance into it's own bottle (I named mine iGuidance )
4) Run Map Loader and load your maps (I installed all of them)
5) tar up the bottle dir: tar czf iguidance.tgz ~/.cxofficebeta/iGuidance
6) Copy the tarball to your carpc

On CarPC:
1) Compile kernel with USB serial driver pl2303 (for BU-353 GPS)
2) Install cxoffice 6 beta.
3) untar the iguidance tarball into the ~/.cxofficebeta dir.
4) Personal Preference: remove the warning when iGuidance starts -
edit ~/.cxofficebeta/iGuidance/desktopdata/cxmenu/Desktop.c^5E3A^5Fwindows^5Fprofiles^5FAll^2BUsers^ 5FDesktop/iGuidance+UMPC
add "nowarning" to the launch line like this:
exec "/opt/cxofficebeta/bin/wine" --bottle "iGuidance" --check --wait-children --start "c:/windows/profiles/All Users/Desktop/iGuidance UMPC.lnk" "nowarning" "$@"

5) Make the serial port available to cxoffice (also make sure your user has read access to the port): ln -s /dev/ttyUSB0 ~/.cxofficebeta/iGuidance/dosdevices/com2
6) I already had extmod in my xorg.conf, so I did not have to edit this.
7) Launch iGuidance by running ~/.cxofficebeta/iGuidance/desktopdata/cxmenu/Desktop.c^5E3A^5Fwindows^5Fprofiles^5FAll^2BUsers^ 5FDesktop/iGuidance+UMPC


That's it! Hopefully some other brave souls will try this out.

how did you integrate iG with myth? (i've got pretty much the same setup as you do.. only touchscreen-interface)

hmm, i just saw that iG-Europe is discontinued, so i'll have to wait (while contributing) for OpenStreetMap to get more cover.. still the question above remains.

timekiller

blk,
Myth has a very customizable interface. Everything is controlled by xml files. I edited the mainmenu.xml file (on my system, the path is /usr/share/mythtv/mainmenu.xml) and created a 'NAVIGATION' button like this:

<button>
<type>NAVIGATION</type>
<text>Navigation</text>
<action>EXEC /usr/local/bin/iGuidance</action>
</button>

Selecting this button, launches /usr/local/bin/iGuidance, which is just a copy of the launcher script created by cxoffice (~/.cxofficebeta/[bottlename]/desktopdata/cxmenu/Desktop.c^5E3A^5Fwindows^5Fprofiles^5FAll^2BUsers^ 5FDesktop/iGuidance+UMPC)

I am also using a touchscreen, and since Myth .20 adds mouse support, I have a nice touch interface to my carpc

I made a theme with modified menus to bring it all together. Anyone is welcome to check it out:

https://www.timekiller.org/carpc/fil...arPC_theme.tgz

It is basically just the "Blue" theme modified to my taste. It looks nice, and works well with the touchscreen.

I am also finally documenting my whole setup (including GPS, internet through Verizon's evdo, and how to stream live tv from my house, through evdo, over bluetooth, and play it on the carpc screen )

Hi,
Nice work, i want to try out linux in my car PC, but can you send me some more details as i don;t have much idea about linux however willing to kill sometime.
My e-mail is uanant@yahoo.com, i have Holux 210 GPS receiver and HP PC woth P-III 512 SDRAM
I would sincerly apprecaite your help
regards

blk

hi uanant, it's cool you show interest in linux, however i think best help is when you try it out for yourself and play around a bit.. we're certainly ready to help but you're also gonna have to help yourself (reading forums,IRC,...) too.
i suggest you get either a liveCD (whole system from CD) or try installing one of the distros and see if you get myth running.. take a distro with myth packages since i don't think the first thing you're gonna want to do in linux is compiling (although it's not really hard, but i think as linux newbie you might not feel at home with the command line (but i might be wrong))

if you have questions concerning usage you're better at asking on IRC (irc.freenode.net on #ubuntu or whatever distro you might start with)

it takes some time to get used to linux, but it's definately worth it! (i switched 7years ago from win and never regretted it) - although using linux doesn't mean you're gonna have to ditch windows
