[Buildroot] Configuring the gpsd package

Hi Baruch,

After doing some more diggings, I found that the reason I don't see the gpsd option in menuconfig, is due to the 2 dependencies BR2_USE_MMU, BR2_TOOLCHAIN_HAS_THREADS which I probably don't have.
Correct me if I'm wrong, but this is the same reason that the changes I make to the config.in are not affecting the gpsd_config.h file?

Anyway, I was able to run the gpsd and use the it in spite of probably not having the two dependencies. 
My questions are:
1. What is the purpose of the two dependencies?
2. How come I was able to use the daemon anyway?

Thank you

Hi Baruch,

Unfortunately I cannot send you my changes because it is not a private file.
I wrote it just like any other source directive.

Regarding the host-scons, I added this package as well so I am able to build the gpsd. (I couldn't build it otherwise).
Again, it is just that I'm unable to make changes to the source gpsd_config.h during build.

Well, I guess I'll have to write a patch for that.......

Can you send your changes as a patch?

No. Confing.in changes should take place once you restart 'make menuconfig'.

Of course. host-scons is listed as gpsd dependency, but you don't have host-scons in Buildroot version 2010.11 unfortunately.
