this linker was not configured to use sysroots
C compiler cannot create executables
在ubuntu下想编译linux kernel,键入命令
make menuconfig时,报出
this linker was not configured to use sysroots
查了一下,是因为/usr/local/bin/ld在编译前没有被配置为configure --with-sysroot
所以下载了binutils-2.22想编译一个带sysroot的
键入命令 ../binutils-2.22/configure --with-sysroot
结果报错:
C compiler cannot create executables,打开目录里的config.log
里面也有this linker was not configured to use sysroots的错误信息,
后来查了一下,/usr/bin目录下也有一个ld,用/usr/bin/ld --sysroot=/试了下,没有报错误信息
this linker was not configured to use sysroots,应该是支持sysroot的
然后就把/usr/bin/ld改名为/usr/bin/ldxxxx,命令为
mv /usr/bin/ld /usr/bin/ldxxxx
然后再执行../binutils-2.22/configure --with-sysroot
make
make install
就成功了,这样就可以编译linux内核了,其实只将/usr/local/bin/ld改名为/usr/local/bin/ldxxxx
也应该能在linux内核目录里执行make menuconfig了
