Scratchbox on Ubuntu Hardy troubleshooting

Posted on Mon 21 April 2008 in Maemo (EN) • Tagged with maemo, nokia, scratchbox, SDK, tablet

Yesterday I upgraded from Ubuntu 7.10 to the new 8.04 RC and I "broke" my Scratchbox installation. I tried to install it again and I had still some problems logging into Scratchbox and installing the SDK.

The I found this page: http://suppressingfire.livejournal.com/35277.html

that explain how to fix these problems. In particular if you get this kind of error trying to log into Scratchbox:

Inconsistency detected by ld.so: rtld.c: 1192: dl_main: Assertion `(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso' failed!

You can fix it in this way:

echo 0 | sudo tee /proc/sys/vm/vdso_enabled

You can read the complete fix in my updated wiki: http://www.ptlug.org/wiki/Howto_Installing_Maemo_SDK_4


Maps for Nokia OS2008

Posted on Thu 06 March 2008 in HowTo, Linux, Maemo (EN) • Tagged with maemo, maps, nokia, tablet

I report this news from Andrew Jorgensen (Monologue):

The Map application for Nokia’s OS2008 (for N800 and N810) lets you download map data for a number of regions. The USA-West and USA-East regions are very large, though, and I have never been able to download them — it always fails about half way through. I know others have dealt with the same problem.

This morning I got a reply from Wayfinder Customer Support:

Dear Sir,
Thank you for contacting Wayfinder.

If the map download fails through the Internet Tablet, you can download the maps from this address: http://www.navicoretech.com/Consumer/Support/Downloads/tablet/en_GB/wfnavigator/

Best regards,

Instructions for installing the map data are on that site. It’s still a slow download but at least you can use a download manager.


wxGTK working on Maemo

Posted on Mon 17 December 2007 in HowTo, Linux, Maemo (EN), Programmazione • Tagged with maemo, SDK, tablet, wx

Reading the official WxWidget blog, I discovered that one of their developer was working to hildonize [WxWidgets]{style="font-weight: bold;"}. I wanted to know if that was just a test or if this library could work in Maemo, so I followed his suggestion and I grabbed the latest SVN sources:

svn checkout http://svn.wxwidgets.org/svn/wx/wxWidgets/trunk wxWidgets

and I compiled it in this way:

cd wxWidgets ./configure --with-hildon make make install

then I grabbed a simple "HelloWorld" from the official documentation. You can find the complete source code here.

I compiled the source code in this way:

g++ hworld.cpp wx-config --libs wx-config --cxxflags -o hworld

then I ran it in the usual way:

run-standalone.sh ./hworld

The result? I think that a screenshoot is better than thousand words :)

wxWindowsHildon

Note: I tested this inside Scratchbox, using CHINOOK_x86 target, so I think it will work fine on Os2008. This could be a good thing to help other developers porting some interesting applications (uhm... aMule for example ;) ) to Maemo.
