Trying to isolate the problem with slmodem package compiles under
kernels 2.6.27, I ran several trials.
If the compile is only done in the drivers/ folder, slamr.ko compile
is successful using either version gcc 4.2 or 4.3 compilers
But as summarized in the short table below, the slmodemd compile in
the modem/ folder fails with the new gcc-4.3 compiler:
Kernel\gcc 4.2 4.3
2.4.21 + failed
2.6.27 + failed
The failure is illustrated below. To sum the problem is that slmodemd
assembly fails upon update of gcc-4.2 to gcc-4.3
If anyone has insights, please respond.
For those of you wanting to use slamr.ko compiled with gcc-4.3,
I suspect the slmodemd compiled with gcc-4.2 would be effective.
However I don't have hardware to run this test.
