Hello,
After installing E18, and getting the TivaC board package with packages manager, when I try to upload a program into the Tiva-C board I get the following error:
fork/exec /home/can/.energia15/packages/energia/tools/arm-none-eabi-gcc/4.8.4-20140725/bin/arm-none-eabi-g++: no such file or directory
Error compiling for board LaunchPad (Tiva C) w/ tm4c123 (80MHz).
If I go the the mentioned directory, I can see that the arm-none-eabi-g++ executable exists by:
$ file arm-none-eabi-g++
arm-none-eabi-g++: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamical
