 |
|
Hello,
When i try to compile any arduino code i get an error,
| Code: |
gcc-config: error: could not run/locate 'avr-g++'
exit status 1
Error compiling for board Arduino/Genuino Uno.
|
In addition gcc-config doesnt seem to work for me,
| Code: |
# whoami
root
# gcc-config -l
[1] avr-7.3.0 *
[2] x86_64-pc-linux-gnu-6.4.0 *
# gcc-config avr-7.3.0
* Switching cross-compiler to avr-7.3.0 ... [ ok ]
# gcc-config -c
x86_64-pc-linux-gnu-6.4.0
# avr-g++
gcc-config: error: could not run/locate 'avr-g++'
# equery list gcc
* Searching for gcc ...
[I-O] [ -] cross-avr/gcc-7.3.0-r3:7.3.0
[IP-] [ ] sys-devel/gcc-6.4.0-r1:6.4.0
# equery check gcc
!!! /etc/env.d/gcc/avr-7.3.0 has incorrect MD5sum
* Checking cross-avr/gcc-7.3.0-r3 ...
789 out of 790 files passed
!!! /etc/env.d/gcc/x86_64-pc-linux-gnu-6.4.0 has incorrect MD5sum
* Checking sys-devel/gcc-6.4.0-r1 ...
1560 out of 1561 files passed

Any idea what could be wrong? |

I removed cross-avr/gcc-7.3.0-r3 and reinstalled it. Following that i set the following PATH (as mentioned in /etc/env.d/05gcc-avr)
| Code: |
#export PATH=/usr/x86_64-pc-linux-gnu/avr/gcc-bin/7.3.0:$PATH
|
avr-gcc-ar and avr-gcc work now. |

So you commented the PATH and the compilation succeeded? |

Thanks, makes sense. So 05gcc-avr's content is irrelevant? |

| It turned out that I had set AR, NM etc variables in make.conf. Removing these variables and exporting the path was enough. |
