Hi~, I got a problem when I run programs on OrpSoC. When I run TEST program on OrpSoC, I can get the or1200-cbasic.vmem file from "orpsocv2/sw/tests/or1200/sim" folader after make-file. And now , i wanted to get the .vmem file according to my test program. I tried to replace the contents of or1200-cbasic.c file with my test program. Unfortunately, it reported errors when make-file : //-------------------------------------------------------------------------------------------------------// /tmp/ccEkn6In.o: In function `main': /home/openrisc/soc-design/orpsocv2/sw/tests/or1200/sim/or1200-cbasic.c:21: undefined reference to `fopen' /home/openrisc/soc-design/orpsocv2/sw/tests/or1200/sim/or1200-cbasic.c:26: undefined reference to `fputs' /home/openrisc/soc-design/orpsocv2/sw/tests/or1200/sim/or1200-cbasic.c:27: undefined reference to `fputc' /home/openrisc/soc-design/orpsocv2/sw/tests/or1200/sim/or1200-cbasic.c:29: undefined reference to `fputc' collect2: ld returned 1 exit status make[1]: *** [or1200-cbasic.elf] Error 1 make[1]: Leaving directory `/home/openrisc/soc-design/orpsocv2/sw/tests/or1200/sim' make: *** [/home/openrisc/soc-design/orpsocv2/sim/run/../../sw/tests/or1200/sim/or1200-cbasic.vmem] Error 2 //--------------------------------------------------------------------------------------------------------// So, can anybody help me! //--------------------------------------------------------------------------------------------------------// my test program : matrix multiplication and write the result to the outputfile. //--------------------------------------------------------------------------------------------------------// #include #include int main(int argc, char* argv[]){ int ma[4][4] = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}; int mb[4][4] = {1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4}; int mresult[4][4]; int i,j; for(i=0; i
