2.13.11 Special Topic: Running External Programs under a DebuggerMathLink allows you to run external programs under whatever debugger is provided in your software environment. MathLink-compatible programs are typically set up to take arguments, usually on the command line, which specify what MathLink connections they should use.
| In debugger: | run -linkcreate | | In Mathematica: | Install[LinkConnect["port"]] |
Running an external program under a debugger. Note that in order to get a version of an external program that can be run under a debugger, you may need to specify -g or other flags when you compile the program. Debugger Set a breakpoint in the C function f.
break f
Breakpoint set: f: line 1
Start the external program.
run -linkcreate
The program responds with what port it is listening on.
Link created on: 2981@frog.wolfram.com
Mathematica session | This connects to the program running under the debugger. | |
In[1]:=
Install[LinkConnect["2981@frog.wolfram.com"]]

Out[1]=

|
| This calls a function which executes code in the external program. | | |
Debugger The external program stops at the breakpoint.
Breakpoint: f(16)
This tells the debugger to continue.
continue
Mathematica session | Now f returns. | |
