[sprintf in kernel space]

I would like to log data in a user servo. My program is composed of a user servo and a background C program. I want them to work as follows:

 

1) composes formatted string in a user servo <- I will use "sprintf" here.

2) passes the string to a FIFO, which I wrote, in a user servo

3) gets the string from a FIFO in a background C program

4) writes the string to a file

 

Are there any established ways?

[sprintf in kernel space]

Hi,

 

I wonder if anyone can give me some advice please?

I would like to use "sprintf" in User Servo Algorithm to format double variables. Are there any functions to achieve this?

 

I found "rtsprintf" in /opt/ppmac/usralgo/usrcode.h in Power UMAC. However, it was just a prototype.

 

Thanks,

[Linker error on IDE 2.0]

Hi,

 

I recently upgraded to the latest IDE. (IDE 2.0 with Firmware 1.6.1.1)

 

My C Libraries can't be linked because of newly added LDFLAGS -Wl,-z,defs.

For example, I get following errors when I build following programs which can be compiled with IDE 1.7.

 

I do these because I have UMAC accessories specific libraries and application specific libraries, and the latter use the former.

 

Are there any ways to change linker options?
