Starting program:  /devl/aaa/BINARY/pfm.sql_Kavitha /devl/aaa/AVP/OCT_TEST /devl/aaa/ASAPDATA/READONLY /devl/aaa/ASAPDATA/READONLY 17 kk12345

Use the "file" or "exec-file" command.**

Please let me know if anybody knows how to resolve this issue.

Answer 1

Invoke gdb as:

gdb /devl/aaa/BINARY/pfm.sql_Kavitha

and then run the program from within gdb as:

(gdb) r /devl/aaa/BINARY/pfm.sql_Kavitha /devl/aaa/AVP/OCT_TEST /devl/aaa/ASAPDATA/READONLY /devl/aaa/ASAPDATA/READONLY 17 kk12345

(gdb) above is the prompt.

If you want to be able to specify the program to execute from within gdb, use file command, as the error message says:

(gdb) file /devl/aaa/BINARY/pfm.sql_Kavitha

followed by the r command as above.

There is some problem with the file you are trying to run from gdb -- either it is a corrupted file or the path is wrong. Try "gdb {filename}".

Answer 3

Instead of a single command, you will need two. One to specify the binary file and another to run the binary. In your case the commands are:

file /devl/aaa/BINARY/pfm.sql_Kavitha
run /devl/aaa/AVP/OCT_TEST /devl/aaa/ASAPDATA/READONLY /devl/aaa/ASAPDATA/READONLY 17 kk12345

Alternatively, instead of using the file command, you can give the binary name to gdb as an argument when you start gdb. Also notice the syntax of the run command. The binary name is not repeated!
