Question

我正在关注http://openrisc.net/toolchain-build.html为openrisc或32构建gcc工具链。我正在手工制作＆＃39;流了，过去了 binutils的
第1阶段gcc
安装linux标头
并且要做的是编译uClibc＆＃39;它由以下命令组成。

$ git clone git://openrisc.net/jonas/uClibc  
$ cd uClibc  
$ make ARCH=or32 defconfig  
$ make PREFIX=${SYSROOT}  
$ make PREFIX=${SYSROOT} install  <br>

当我运行ARCH = or32 defconfig＆＃39;时，我收到此错误。

有没有人有同样的问题？我使用的是CentOS 6.4。

gcc按顺序

搜索系统中的头文件

/usr/local/include  
libdir/gcc/target/version/include    (libdir was /usr/lib in my case)  
/usr/target/include  
/usr/include

我的系统在/ usr / include下有sys / syscall.h，以便在使用uClib / include下的sys / syscall时使用该文件。所以我添加了-nostdinc，以便gcc不搜索标准的include路径。现在变成了 make PREFIX = $ {SYSROOT} -nostdinc
它有效！
以下命令也被修改了
make PREFIX = $ {SYSROOT} -nostdinc install

干杯！

错误编译uClibc（__ NR_or1k_atomic未声明）
