Linking problem with the c5505 CSL...

Buliding a simple main as this:

#include "csl_i2c.h"
void main(){
CSL_I2cSetup i2cSetup;
I2C_setup(&i2cSetup);
}

even if I linked the csl header in the build properties, I obtain three errors:

errors encountered during linking; "prova.out" not built

Linking failed. Check the Console window for details.

unresolved symbol _I2C_setup, first referenced in ./main.obj

...and on the console I read this:

**** Build of configuration Debug for project prova ****

What should I do?

You have to determine which code contains I2C_setup() function. Is that a TI library? A third-party library, for
example if you're using a third-party development board (Spectrum Digital etc) ?

Once you know, then you can add a file in whatever format is available (.lib, .obj, our C/C++ source) to your project,
then rebuild.

Looking at it a second time, it does look like you have provided the
necessary information. I might need to upgrade to glasses or better focus ;)
But still, try my suggestion.
You have already linked in the rts lib it looks like: -l"rts55.lib" so
doing the same for the csl lib might help.

Good luck!

Hi Andrea,
do you still have this problem?

If possible, could you paste all the flags you send to the compiler and
linker?

Looking at the messages you get, it looks like you don't link in the csl
library, as it is the linker that complains. You have provided the compiler
with the header files, and all is well there. But then when the linker tries
to find the symbols they are nowhere to be found. If my guess is correct you
need to add a flag such as "-lcsl55x.lib" or something like it. You need to
find out the correct path to provide to the linker.

Hope this helps,
Sima

Hi Sima, thanks for your help. Now I've resolved the problem, it didn't work because the build properties weren't set correctly. The main problem was the memory model which was set as "small" instead of "large". Thank you again for your help.
