i have a script that takes c++ source code from an HTML textbox ( written by user )
and pass it to php and this php code writes the source code to a *.cpp file
and then usuing exec() i compile that .cpp
the problem is when i use exec() on any program it captures the output and put it in an array
exec("help.exe",$array);
and this array will hold the lines displayed
but when i use exec() on mingw32-g++ it doesnt store the output in the array no matter what i do
what are the limitations for exec or system to store the output ??
i made two programs to output string "hello world" using cout and printf and both work fine and the php stores the output "hello world"
can anyone help PLEASEwell, when compiling an app with g++ isn't there supposed to be no output if the program compiled fineyes
but if thers an error it should display each error on a different line
like this :
mingw32-g++ output: {ERROR GOES HERE}
but it doesnt ... it doesnt capture any output at allAren't error messages directed to stderr instead of stdout? Maybe tacking "2>1" on the end of the commandline to redirect stderr back to stdout would help?yeah weed is right, exec wont pick up whats sent to stdout since thats immediately flushed, and the compiler sends those errors to stderr.but its not always error messages
its just any output either that compilation failed or compilation results
you guys know mingw32 ??
and can you elaborate the "2>1" part ?
