A minor clarification on the program below

I think the issue was by ths following , logger.write and logger.flush are simple aliases to the user defined functions _write() and _doNothing() respectively in the same module. Imagine a simplified scenario,
code :
# User defined function
>>> def _write():
...    print 'Inside _write()'

# Sample Logger class
>>> class Logger:
...    pass

# Object of type Logger
>>> logger = Logger()

# Simply adding a new attribute 'write' to the object 'logger'
# and point to the user defined function name.
# This will create an alias.
>>> logger.write = _write
>>> logger.write()
Inside _write()

# Proof that both 'logger.write' and '_write' are indeed 
# same 
>>> id(logger.write) == id(_write)

help you fix your problem You haven't tried googling the error message, have you... this is a linker error telling you that there's no function defined with the name If. Maybe you wanted to write a branch statement with the if keyword instead... C is case sensitive.
Sidenote: after you fixed this, remove the semi-colon from after the if, because that's an empty statement. Then, indent and format your code because it's an unreadable utter mess currently. You don't only have minor problems with your code, you have major problems with the basics.

To fix this issue Your problem is that you only call device_create() for the first device. alloc_chrdev_region() only allocate major/minor numbers but it does not actually create the device structures in the kernel. The dev_t returned by alloc_chrdev_region() represents the first of your five major/minor numbers. You need to use a for loop, increment the minor number and then call device_create() on all of them.
Don't forget to destroy all of them in the exit function.

wish help you to fix your issue A program returns a version string of this regex type [0-9]{1,}\.[0-9]{1,}\.[0-9]{1,}\.[0-9]{1,} on the command line. Therefore the output looks like this: , You can use this single command line in your batch file:
code :
for /F "tokens=1-3 delims=:. " %%I in ('a.exe --version') do if /I "%%I" == "Version" set "Version=%%J.%%K"

will help you When you have an array of 0 (that is: zero) characters, you cannot save anything in it, not even a single bit. Make that array "large enough" (whatever that means for you) or better use a std::string instead.
Oh, and compile your code with all compiler warnings enabled. When you have understood and fixed all these warnings properly, you program should work much better. (Hint: assignment inside conditional)

I hope this helps . You're at the mercy of whatever algorithm and runtime environment Gild use for judging these. I think that compiler flags are probably a red herring; I suspect that submitting in "release mode" turns on -O2 or -O3 for you.
I suspect it's a question of optimising for memory use, possibly memory locality. That stringstream and set could get very expensive, for example; in your shoes I'd start looking to see whether there was another way, perhaps with a more tailored algorithm.
