I run hdhomerun_config on my pogo v3 (works on v2 also). Compiled 12/19/2011 for both arm (pogo) and mips (my asus rtn-16 router) so it is not the most recent code but it works well enough.
Here is a download link:
hdhomerun_arm_mips.tar.gzunzip it to find
$this->bbcode_second_pass_code('', '
/arm/hdhomerun_config
/arm/libhdhomerun.so
/mips/hdhomerun_config
')
The arm lib is only for writing other code to use the hdhomerun. You don't need it if all you want is hdhomerun_config.
btw, you do not need to cross compile. You can compile right on the pogo. To load the packages required to compile do:
$this->bbcode_second_pass_code('', '
pacman -S kernel26-headers file base-devel abs
')
as found under
Installing Native Build Essentials. It has been awhile since I installed these packages but according to my notes it will ask two questions: the first answer is "2" for linux-headers and the second is "all" for base-devel. That may differ now so see if any questions arise and if these answers make sense.
The gui is a pita to get going but as you say you don't need that. So if memory serves, you can skip the ./configure, cd straight into the directory/libhdhomerun dir, make and you will then have hdhomerun_config (as well as libhdhomerun.so) in that dir. Then rather than doing sudo make install, just copy it anywhere you like that is on your PATH env variable. And no need for the ldconfig.
You can use the hdhomerun_config save command to save streams. On a pogo v3 I was able to get as many as 3 at a time successfully. That encouraged me to try and put mythtv on. That has been an adventure. I have 3 pogos, a v3 B01 booting off a sata drive, a v3 P21 with only a USB flash drive, and a v2 E02 with a USB hard drive. I run mysql with the mythtv db on the B01 along with the master backend. I run a slave backend on the E02 which does all of the recording, and I run mythweb under lighttpd on the P21. I tried the mysql db on the E02 with its faster cpu and more memory but mythfilldatabase took about 4 hours I think because it has no sata and the disk is the bottleneck. On the B01 it takes about an hour 45 mins. mythweb works but is a bit slow. I turned off previewgen as that is too resource intensive and I don't care about it. I can only record one show at a time successfully but at least it works. I really wish there were a v2 pogo with sata and even better with 512 MB RAM. I am thinking about looking into a cubox.
