I got the reason for one error folder was not in path ! can any one tell me how can i set path in unix server without using GUI after putting everything in path following is error i am getting when using mex nfftmex.c mex nfftmex.c nfftmex.c:30:26: error: mexversion.c: No such file or directory nfftmex.c:43: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’ nfftmex.c:55: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’ nfftmex.c:73: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’ nfftmex.c:96: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’ nfftmex.c:116: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’ nfftmex.c:122: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘int’ mex: compile of ' "nfftmex.c"' failed. ??? Error using ==> mex at 221 Unable to complete successfully. I have no idea what mexversion.c is its one of the files used in nfftmex.c following are lines #include <complex.h> #include <string.h> #include <stdio.h> #include "nfft3.h" #include "infft.h" #include "nfft3util.h" #include "imex.h" #ifdef HAVE_MEXVERSION_C #include "mexversion.c" #endif
