[SOLVED] Error in using system() for compilation

Question

I am trying to invoke the g++ compiler to generate assembly and preprocessor files for a C++ source code using system(). I have the compiler located in a different drive, and the folder name contains spaces, so I decided to use the following command :

"F:\ Files\MinGW GCC 7.2\MinGW\bin\g++.exe" -std=c++17 -S -save-temps "H:\All C++ Files\Rough\Main.cpp"

However, when I run the program, I get the following error :

" 'F:\' is not recognized as an internal or external command, operable program or batch file. "

The command, however, works just as it should when pasted inside cmd.

Why does system consider only the F:\ as the specified command? Why does it ignore the rest of the statement?

Here is the code being used for the same.

Answer 1

Hi Kinshuk Vasisht, maybe try with ShellExecute or ShellExecuteEx function, it supports parameters/arguments:

Best of luck : )

Danik 45 Don't worry. You can learn the basics from the C++ Tutorial here. But next time, try posting such questions in your feed.

Answer 4

Hi Kinshuk,

Why are you inserting a space between 'F:\' and 'File\' ? Does it really exists?

Answer 5

Ipang Thank you very much for the suggestion. I'll try it and let you know if it worked for me...

Edit : ShellExecute worked like a charm. Thank you very much!

Answer 6

Kinshuk Vasisht share code link please? so others can learn also : )

Answer 7

Hi Kinshuk Vasisht, can you provided more details about the environment you are compiling/executing your code? can you provide a minimum piece of code in which you can observe the problem?

I will try to reproduce the error in my machine. Than I will be able to help you more.

Answer 8

Mark

I am using a Windows 7 64 bit PC, and am compiling my code using GCC v7.2, which I have inside a MinGW Package.

The code can be found attached with the question itself as a Code Playground link.

Mark Unfortunately, the space does exist. I mistyped the name during creation.
