arm-ssv1-linux-gcc -Wall -O2 -Wl,-s -lm -o essai essai.c

i copy the /usr/local/arm-ssv1-linux/sysroot/lib/libm.so.6 into DNP/9200 into directory /lib


My essai.c program is :
#include <stdio.h>

Hello sandsfr,

first check the current kernel version on DNP/9200 with uname -r on your Telnet console.

for kernel 2.6.16.20:

1. Run the compiler with:
   

   Code:

   export PATH=/usr/local/arm-ssv1-linux/bin:$PATH arm-ssv1-linux-gcc -Wall -O2 -Wl,-s -lm -o essai essai.c

   
   
2. Copy the file /usr/local/arm-ssv1-linux/sysroot/lib/libm-2.3.5.so to DNP and store it as /flash/libm.so.6
   
3. Copy the file "essai" into directory /flash on DNP/9200
   
4. Make the file executable with "chmod +x /flash/essai"
   
5. Run the program on DNP/9200 with

   Code:

   LD_LIBRARY_PATH=/flash /flash/essai

   
   

for kernel 2.4.27:

1. Run the compiler with:
   

   Code:

   export PATH=/usr/local/arm-linux/bin:$PATH arm-linux-gcc -Wall -O2 -Wl,-s -lm -o essai essai.c

   
   
2. Copy the file /usr/local/arm-linux/arm-linux/lib/libm-2.1.3.so to DNP and store it as /flash/libm.so.6
   
3. Copy the file "essai" into directory /flash on DNP/9200
   
4. Make the file executable with "chmod +x /flash/essai"
   
5. Run the program on DNP/9200 with

   Code:

   LD_LIBRARY_PATH=/flash /flash/essai
