Question

I try to run PHP script and to get the ouput from stdout, the code looks like this:

using namespace boost::process;

std::string exec="php";
std::vector<std::string> args;

// I must to throw the exe by argument
args.push_back("php");
args.push_back("a.php");

context ctx;
ctx.stdout_behavior = capture_stream();
child c = launch(exec, args, ctx);

pistream &is = c.get_stdout();

There is no info at stdout, but at stderr I get:

“boost::process::detail::posix_start: execve(2) failed: Permission denied”

And when I run exactly same command in terminal it works fine!

Any solutions?

Thanks..

Thanks @hakre, you gave me right direction!

I went to /usr/bin/ to check the permission and saw php5 command with same permissions as php (php is link to php5).

I don’t understand why, but when I replaced the command to php5, the previous error replaced by: “No such file or directory”, and when I gave full path, it works fine:

exec="/usr/bin/php5";
args.clear();
args.push_back("php5");
