libmodbus for ARM

hi,
you have to include modbus headers in your gcc path (<gcc> -l <path to
modbus dir>)
I'm not sure of the syntax, please check using gcc help

bye

thanks for ur reply.. I did d same before posting my query.. but it also didnt work.. did u compiled the applications for any development board having ARM processor..
If anybody has worked on it previously plz guide me.. its urgent for me to get it worked...
The thing is I hav a development board having ARM9 on it.. its connected to the drive through modbus.. I hav to communicate wit it.. I am able to write to the drive but not able to read.. so I want to use libmodbus for the same..
I hav written the application but now want to compile it for arm board n m using cross compiler arm-linux-gcc-4.3.2
but hav errors in compiling it.. it is working properply for gcc compiler.. but not for cross compiler..
I hav followed proper step.. It would be great if someone can guide me wit proper steps...
Thanks in advance....

You can try just copy the modbus.h (under libmodbus/src folder) in the same folder with the file you want to compile
