我想在一个新项目中使用avr-gcc(8.1.0)的最新版本,这在ubuntu的package-manager中是没有的,所以我自己用这个网站上的build-script编译了它:https://gist.github.com/zkemble/edec6914ba719bf339b1b85c1fa792dc(我在Ubuntu 16.04下工作,所以我设置了BUILD_WIN32=0
和BUILD_WIN64=0
,以便只构建Linux版本)
编译成功完成后,我尝试通过手动复制输出文件和目录来使其可用,如下所示:(替换名称相同的先前存在的文件)
./linux/bin/*
至/usr/bin/
./linux/lib/gcc/avr/8.10
至usr/lib/gcc/avr/
./linux/share/man/*
至/usr/share/man/
./linux/libexec
至/usr/
./libc/avr/*
至/usr/lib/avr/
./libc/avr/include/*
至/usr/lib/gcc/include/
这是一种尝试和错误,也许有些路径是错误的,但它似乎是合理的,当比较旧的文件从旧的gcc安装。avr-g++ -v
给我正确的版本“gcc版本8.1.0(GCC)"。
(我使用eclipse oxygen作为IDE,因此以下命令是自动生成的,请原谅命令过于臃肿)-使用
avr-g++ -v -I"/media/Data/Eigene_Dateien/Valentins_Dateien/Projekte/Software/ATmighty/src/ATmighty"
-Wall -g2 -gstabs -Os -ffunction-sections -fdata-sections -fno-exceptions
-std=c++11 -mmcu=atmega2560 -DF_CPU=16000000UL -MMD -MP -MF"main.d" -MT"main.o"
-c -o "main.o" "/media/Data/Eigene_Dateien/Valentins_Dateien/Projekte/Software/ATmighty/src/QuickTests/main.cpp"
出现以下错误:as: Unknown option: »-mmcu=avr6«
。(请参阅下面的完整详细输出)。
看起来新的avr-g++
编译器没有使用正确的avr-as
文件,而是使用了主机默认的as
汇编程序。但是avr-as
位于\usr\bin\
中,与as
所在的文件夹相同。
如何设置avr-g++ 8.1.0-toolchain以使其正常工作?我实际上想试用一些新的avr-g功能,而官方资源库中的默认版本非常旧(一些4.x版本)
