[英]Cross-compile to Linux from OS X
I want to compile binaries for a Linux server from an OS X 10.7 + Eclipse build system. 我想从OS X 10.7 + Eclipse构建系统编译Linux服务器的二进制文件。 This means a GCC cross-compiler.
这意味着GCC交叉编译器。 I'm starting from native 4.7.1 and shooting for a host 4.7.1.
我从本机4.7.1开始,为主机4.7.1射击。
Most online instructions are specific to embedded development. 大多数在线说明都特定于嵌入式开发。 I want to use libstdc++-v3 and glibc, which make it a little different.
我想使用libstdc ++ - v3和glibc,这使它有点不同。
Install packages 安装包
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 msgfmt
Make and install binutils-2.22 制作并安装binutils-2.22
make all-gcc
and make install-gcc
make all-gcc
和make install-gcc
Used the following config: 使用以下配置:
$ ../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
$ ../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 将构建环境指向交叉编译器
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-cpp
Build glibc-2.16 using the config 使用config构建glibc-2.16
../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
../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
glibc build fails before long. glibc构建不久就失败了。 This message appears many times:
此消息多次出现:
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.
This may be normal, though. 不过,这可能是正常的。
Then it fails to produce stdio_lim.h
. 然后它无法生成
stdio_lim.h
。 With make -d
, I get this: 使用
make -d
,我得到这个:
Successfully remade target file `/Users/dkrauss/Documents/work/glibc-build/csu/abi-tag.h'.

This is the first header it attempts to build in bits
. 这是它尝试以
bits
为单位构建的第一个头。 There is a file stdio_lim.h.in
, which is the only .in
file in its directory. 有一个文件
stdio_lim.h.in
,它是目录中唯一的.in
文件。 Should some rule be connecting .st
to .in
? 如果有些规则是连接
.st
到.in
?
In order to properly build glibc, you need the header files from a Linux system - probably the kernel headers are sufficient. 为了正确构建glibc,您需要来自Linux系统的头文件 - 可能内核头文件就足够了。
This is due to the fact that those headers are needed in any normal build of the software for that system, and the same is no different when cross-compiling. 这是因为在该系统的软件的任何正常构建中都需要这些头,并且在交叉编译时也是如此。
It's been a long time since I worked on creating cross-compilers, so I can't tell you how to get the build of glibc to see the headers, but I believe it can be done in a straight-forward manner. 自从我创建交叉编译器以来已经很长时间了,所以我不能告诉你如何使用glibc来构建标题,但我相信它可以直接进行。
