"Connection Refused" error when starting a debug session on Linux

Question asked by LPCware Support on Mar 31, 2016

On some Linux systems, when starting a debug session a "Connection refused" error may be displayed.

This is because a critical system library is not installed where we expect to find it. The location of the library depends on the version of Linux you are running,

Note: It is critical that you use the 32-bit version of the library.

To resolve this issue, open a Terminal Window and execute the following commands


64-bit systems


After installing the 32-bit compatibility libraries (as described in the LPCXpresso User Manual)

cd /lib/i386-linux-gnu sudo ln -sf



Fedora and OpenSUSE (32-bit)


[Note that OpenSUSE is not an officially supported platform.]

cd /usr/lib sudo ln -sf
