Device::SerialPort in Perl (optware)

[halteren]

Hi,

I've managed to put OpenWrt (Kamikaze 7.06) on my WL 500GX device, with a small modification to the ftdi_sio kernel module. As a result I now have a serial port device on /dev/usb/tts/0 that controls an FHZ1300PC box (for controlling lights and heating).

I would like to use a Perl script (from http://www.koeniglich.de/fhem/fhem.html) to drive the FHZ1300 box. So, I installed Perl from optware, after following instructions from http://www.nslu2-linux.org/wiki/FAQ/Optware-uClibcBuild to upgrade ipkg and uclibc.

Now that I got this far, I found out that Device::SerialPort is not available from the optware feed.

Is there someone who can make Device::SerialPort available? - Or, alternatively, how can I build that package myself?

Thanks,
Aart.

You can prepare package yourself. Send me a .mk when done and I will include it.

Using the perl-device-serialport.mk file below I'm getting a long way, but I'm not there yet. Apparenty the Device-SerialPort configure script does not generate a Makefile. Can you have a look?

This makefile looks like it misses ipk build part. You can start with creating
stock one with simple

mv make/perl-device-serialport.mk /tmp
make make/perl-device-serialport.mk
And then change variables there.

[halteren]

I 've recreated the .mk file using your recipe (see attachment), but that really is not the problem. After the configure phase no Makefile is created.


checking normal CTS/RTS flow control... yes
configure: creating ./config.status
config.status: creating config.h
touch /home/user/openwrt/optware/builds/perl-device-serialport/.configured
rm -f /home/user/openwrt/optware/builds/perl-device-serialport/.built

make[1]: Entering directory `/home/user/openwrt/optware/builds/perl-device-serialport'

I can create a Makefile manually for Device-SerialPort, using 'perl Makefile.PL', but the resulting Makefile is not suitable for cross-compiling. I dont know how to convince Makefile.PL to output a suitable Makefile.

See changeset #6280 (http://trac.nslu2-linux.org/optware/changeset/6280) for serial port makefile. I have not tested it, but I expect that it works.
It was somehow tricky as it uses configure inside Makefile.PL. I am still not shure it configure created config.h well. If not then we need config.cache run
with configure on router itself.

Visit serial port homepage (http://sendpage.org/device-serialport/) for instructions and report if it does not work.

Note that package may not appear for day or so as we are stopped autobuild machine to softland new OpenWRT Kamikaze Optware targets.

Thanks for your efforts. It seems to work OK.
