Re: PCTel Driver fails to compile, found a fix for 2.6.38.8

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



@all

the driver compiles after the fixes, but some things don't look correct:

checking for running kernel version...2.6.38
checking for ptserial...ptserial-2.6.c
checking for gcc...4.5.2 (4.5)
checking for kernel gcc version...4.5.2 (4.5)
searching for kernel includes...found at
/lib/modules/2.6.38.8-porteus/build/include
checking for autoconf.h.../lib/modules/2.6.38.8-porteus/build/include/linux/autoconf.h
checking for asm/mach-default...yes
checking for kernel version in linux/utsrelease.h...UTS_RELEASE is
2.6.38.8-porteus
checking type of tty_struct.count...int
checking for presence of udev...present (kernel version 2.6.13 or later)
detecting your modem...found. Your modem is a pct789 type modem.

Will wait for a better fix than the one I came up with :(
