我希望从OS X 10.7 + Eclipse构建系统为Linux服务器编译二进制文件，这意味着需要使用GCC交叉编译器。我从本地4.7.1版本开始，并且目标是主机4.7.1。
大多数在线指南都是针对嵌入式开发的，但我想使用libstdc++-v3和glibc，这使得情况有些不同。
成功的方法：
Install packages
port install gcc47 export CC=gcc-mp-47 export LD=ld-mp-47 export CXX=g++-mp-47 export CPP=cpp-mp-47 port install gmake ln /opt/local/bin/gmake /opt/local/bin/make port install gsed ln /opt/local/bin/gsed /opt/local/bin/sed port install gawk port install autoconf port install msgfmtMake and install binutils-2.22
make all-gccandmake install-gccUsed the following config:
$ ../gcc/configure --enable-languages=c,c++,objc,obj-c++ --with-gmp=/opt/local --with-mpfr=/opt/local --with-mpc=/opt/local --prefix=/usr/local/cross/linux --target=x86_64-pc-linux-gnu --disable-nls
Point the build environment at the cross-compiler
export CC=/usr/local/cross/linux/bin/x86_64-pc-linux-gnu-gcc export LD=/usr/local/cross/linux/bin/x86_64-pc-linux-gnu-ld export AR=/usr/local/cross/linux/bin/x86_64-pc-linux-gnu-ar export CXX=/usr/local/cross/linux/bin/x86_64-pc-linux-gnu-g++ export CPP=/usr/local/cross/linux/bin/x86_64-pc-linux-gnu-cppBuild glibc-2.16 using the config
../glibc/configure --host=x86_64-pc-linux-gnu --build=x86_64-apple-darwin11 --prefix=/usr/local/cross/linux/ --with-binutils=/usr/local/cross/linux/bin/ --with-headers=/usr/local/cross/linux/include/ libc_cv_forced_unwind=yes libc_cv_ctors_header=yes libc_cv_c_cleanup=yes
故障：
在很短的时间内，glibc构建失败。此消息会出现多次：
In file included from ./sysdeps/unix/sysdep.h:20:0,
from ./sysdeps/unix/x86_64/sysdep.h:18,
from sysdeps/unix/sysv/linux/x86_64/sysdep.h:22,
from <stdin>:1:
sysdeps/unix/sysv/linux/sys/syscall.h:24:24: fatal error: asm/unistd.h: No such file or directory
compilation terminated.
这可能是正常的情况。
然后它无法生成
stdio_lim.h。 我使用 make -d 命令，我得到了这个结果： Successfully remade target file `/Users/dkrauss/Documents/work/glibc-build/csu/abi-tag.h'.

这是它在bits中尝试构建的第一个标题。有一个名为stdio_lim.h.in的文件，它是其目录中唯一的.in文件。是否应该将.st与.in连接起来？
