Hello List,

first mail, please be gentle. I wish to create a new rootfs for my ARM920T
microcontroller based device using BUILDROOT. The device has a serial port
attached huawei 3G modem that could theoretically be used with stock
chap/ppp. I do vividly remember though my aggreviance with this before
finding wvdial, a simple, easy-to-use package to configure, initialize,
start, and monitor the pppd. Unfortunately, wvdial just can not be added to
my buidroot created rootFS. My question to the listmembers is twofold:
1) am I right to assume that ofono is more than capable replacing my old
friend vwdial as shown here:
http://ofono.org/wiki/how-work-newly-bought-3g-key
2) if so, is there a makefile I could use to add ofono to my otherwise
functional buildroot conf?

Any help would be much appreciated.

TIA,
Jerry O_O

Yes, but make sure to use udev instead of mdev (AFAIR mdev is the
default in buildroot).

Other problem is that buildroot uses uClibc. Denis, do you know if
there's any problem in building oFono with uClibc?

If there is, you'd need to provide your own toolchain (take one from
CodeSourcery).

oFono uses autotools for building. If you are using the git
repository, you need to run './bootstrap && ./configure' first. Then
you'll have a Makefile.

you just need libudev actually, but it does depend on udev.

There might be small problems, but none that can not be fixed. To be
fair, I have not yet tried to get it all compiled with uClibc.

If you use a packaged tarball, then only ./configure is sufficient.

However this question might be more targeted to a buildroot specific .mk
file and no, we do not have that.
