hello,
I had to re-install my Ubuntu 16.04 with kinetic for some reasons. How ever, I tried to re-install all the work I've done before on the project. All the workspaces where saved in my onwcloud, so i thought it should be an easy thing to do. Wrong :)
As I tried just to recompile the workspace with catkin_make everything failed an i tried to build from a new and clean workspace.
There is a node that uses some serial communication,so i need to add the rosserial pkg to my system.
First try by sudo apt-get install ros-kinetic-serial. then I did catkin_make. Everything fine so far. BUT when i start the node with rosrun an exeption ocoured:
IO Exception (13): Permission denied, file /tmp/binarydeb/ros-kinetic-serial-1.2.1/src/impl/unix.cc, line 151.
Just to check, i manually install the serial-pkg in my workspace and build both mith catkin. Now ther ist that error:
IO Exception (13): Permission denied, file /home/eddie/owncloud/eddie_ws/src/serial/src/impl/unix.cc, line 151.
which is basicly the same.
The piece of code with this revers to ist that: (l.151 is the default case)
void
Serial::SerialImpl::open ()
{
if (port_.empty ()) {
throw invalid_argument ("Empty port is invalid.");
}
if (is_open_ == true) {
throw SerialException ("Serial port already open.");
}
fd_ = ::open (port_.c_str(), O_RDWR | O_NOCTTY | O_NONBLOCK);
if (fd_ == -1) {
switch (errno) {
case EINTR:
// Recurse because this is a recoverable error.
open ();
return;
case ENFILE:
case EMFILE:
THROW (IOException, "Too many file handles open.");
default:
THROW (IOException, errno);
}
}
reconfigurePort();
is_open_ = true;
}
Does anyone has any ideas? thank you all! p.s. the hole thing worked very good before the re installation.
