I listed the pre-generated file "A.lp" in the same folder. After release the c++ code, and input the command "XXXX\test.exe A.lp", it always comes out an error message like this:CPLEX Error 1423:could not open lp file for reading. Would someone help me on this? Thanks a lot!!

Is the file A.lp in the same folder from which you run the program (which is not necessarily the colder that contains test.exe)?
Could you tell us

• which folder contains the file A.lp?
• which folder contains test.exe?
• from which folder do you start test.exe?

If you do

FILE *tmp = fopen(argv[1], "r");
if ( tmp ) {
   printf ("Could open file '%s'\n", argv[1]);
   fclose (tmp);
}
else {
   printf ("Could not open file '%s'\n", argv[1]);
}

right before the call to CPXreadcopyprob(), what does this print?
