Code Blocks redirecting input output

Question

I'm new to code blocks, and I can't seem to get it to work with command line arguments of < input > output. Does anyone know how to?

I'm currently able to read a file passed from argv[1] but, the program doesnt automatically read the input from the given file nor does it right the output to the file output.

I'm aware it is on set program's arguments, my arguments line is: list.txt < input > output

After some research I saw a guy doing it like this: < ./input > ./output, seems like running a program to give the input and output, anyways, I've also tried that to no avail. Do I need to use file handlers to interact with it? It doesn't make sence, simple getchar() should read from the passing input file.

What am I missing here?

Thanks in advance

I have found a way how to do it in CB 13.12

Tools -> Configure Tools -> Add:

Name: whatever
Executable: C:\Windows\System32\cmd.exe
Parameters: /C ${TARGET_OUTPUT_BASENAME} exampleArg1 <inputFileRedirect.txt
Working Directory: ${TARGET_OUTPUT_DIR}

It basicaly launches windows console and passes Parameters to it. You can also assign keyboard shortcuts to these tools. The only disadvantage i can see is that the tools are not project specific.

I've been working with Code::Blocks for some time now and just recently noted the same at least with Code::Blocks 12.11 in Windows. The redirections > and < do not work in the Project -> Set programs arguments...

A hackish solution is to do the execution in post-build step.

Right click project name -> Build options... -> Pre/post build steps -> Post-build steps:

cmd /C cd /D "bin\$(TARGET_NAME)\" & YourApplicationNameHere.exe >output.txt 2>errors.txt

And check the checkbox Always execute, even if target is up-to-date. Now hit Ctrl+F9 and the program is executed as a last step of the building process.

I think it is the problem of cb_console_runner.exe which launches your program in IDE. ConsoleRunner can not interpret redirection symbol. So, I add some code to the original code of codeblocks 13.12. Please copy linked file to [cb folder]. (Don't forget back-up the original.)
