Problems with linux driver

[Nobody/Anonymous]

Of course I tried to find a solution before writing this post!!
I can't compile the driver on linux.
I saw on a thread on this forum that someone says taht it is necessary to change some values on the *.c file, includes path and to remove a line of a var "owner".
I changed the include value and run make command and it returned some errors and warnings, so I removed the "owner" variable and run the make command.
This is what I got:

Hi!

A few days ago, I found the following site.

http://kerneltrap.org/index.php?q=mailarchive/git-commits-head/2009/1/8/4638814

I copied the three files in my kernel source tree, made a config and compiled everything. The new module loads fine, but I can't connect to my PLC. The command

testMPI -3 -d /dev/ttyUSB0,

which worked before I upgraded my OS to OpenSuSE 11.0 with kernel 2.6.25.18-0.2-pae, only returns "I/O possible". I use libnodave v0.8.4.4.

Before the system upgrade, I used OpenSuSE 10.2 with kernel 2.6.18.8-0.5-default. I think something in the kernel changed, and that is why the kernel module doesn't work anymore.

Live long and prosper!

Hi!

I found a solution for my "I/O possible" problem. I had to edit setport.c and include the call

signal(SIGIO, SIG_IGN);

as mentioned here:

http://www.linuxforums.org/forum/linux-programming-scripting/126497-read-i-o-possible-2.html

Don't forget to include signal.h.

Bye.

hello,

i have the same problem on debian with the 2.6.26 kernel. with kernel 2.6.18 there is no problem with all.

please post your new code of the "setport.c".
so i can try the changes with the kernel 2.6.26 and my simatic s5 (cpu 942).

best regards
dirk t.

Hi!

Here is my patch to setport.c. Use patch to add it to the source file.

Ok, thank you very much.
I'll try this solution.
