I know the there is a .ipk for GPSD 2.30 but that version is not stable/compatible with Kismet so I need to build a .ipk using the GPSD 1.10 source

So, I read the Howto on building packages and I'm using the latest OpenWRT SDK. I downloaded the and modified as necessary the current GPSD Config.in , gpsd.control and Makefile

In the makefile I changed the
PKG_VERSION
PKG_MD5SUM
PKG_SOURCE_URL
lines as that's all that appeared to need changing.

I tried compiling and here's what happened

I running Ubuntu Linux 5.10 and I'm assuming that I'm just missing a package or it's a configuration issue.

I hate to have to bump this but I'm still banging my head against a wall trying to get this error resolved. ANY help would be appreciated. No-one has a clue what's going on here?

Remove this check from the configure script. A lot of configure scripts are broken for cross-compiling...

Thank you. I'm one step closer. It made it alot further in  the compile. I'm now off to track down the cause of
impossible constraint in 'asm' error.

By "not stable" do you mean that kismet keeps saying "Lost GPS signal", "Acquired GPS signal"? I had the same issue, it might be because of a mode that gpsd initializes the receiver in, but I didn't look into it further because gpsd 2.09 has always worked for me (on laptop previously), so just change PKG_VERSION to 2.09, wget the tarball and md5sum, make package/gpsd-install, should work.
But if that version doesn't work for you either, try running the NMEA commands from kismet's gpsd.cc manually through gpsd using nc localhost 2947 (or just add some debugging to the code) and see where it's failing.

This is strange.T his was compiling for me direct from svn as of as recently as last week. Working with kismet as well. The gpsd package within kamikaze hasnt' changed since 10/31/05. Did something in one of the dependancies change?

Actually I was having the lost/acquired problem, but I attributed that to having the GPS indoors not to gpsd itself.

The current release of Kismet ( not newcore) does not support the 2.x version of GPSD due to the autobauding code in GPSD. It causes the lost/acquired issue as well as other issues (driving at 70mph displays only 20mph through kismet). Dragorn has completely re-worked this in the newcore release and it will support GPSD 2.x. There's rumors that GPSD may not be needed an kismet will talk directly to a GPS device.

I've had issues with GPSD 2.30

Anyway, I've been unable to even get the 2.30 version to compile using the SDK on my laptop due to assembler unrecognized opcodes. I'm trying to get a cross compiler working now and then maybe get kismet newcore cross-compiled for the WRT otherwise it's back to getting 1.10 to work.

current errors using the SDK to compile GPSD 1.10

In case other have issues here's the solution

replace
-I/usr/include
with
-I/home/user/trunk/openwrt/staging_dir_mipsel/usr/include

This can be done with the use of CFLAGS and CPPFLAGS (consult your source ./configure --help

otherwise you can search and replace in the the Makefile

The discussion might have continued from here.
