如何使ARM的交叉编译在Mac OS X（错误：无效的房源选项'R' - 交叉编译错误） [英] How to make ARM cross compilation on Mac OS X (error: invalid listing option `r' - cross compiling error)

问题描述

我试图建立在Mac OS X上的gcc交叉编译器，目标是 ARM-ELF-EABI 。

I'm trying to build a gcc cross compiler on Mac OS X, the target is arm-elf-eabi.

这是我迄今所做的：

我试过不使用铛/ LLVM从Mac，所以我从酿造使用的GCC-4.8。

I tried not to use clang/llvm from Mac, so I used the gcc-4.8 from brew.

brew tap homebrew/versions 
brew install gcc48
brew install binutils

建筑之前，我设置环境变量：

Before the building, I set the environment variables:

export CC=/usr/local/bin/gcc-4.8
export CXX=/usr/local/bin/g++-4.8
export CPP=/usr/local/bin/cpp-4.8
export LD=/usr/local/bin/gcc-4.8
export PREFIX=/opt/cross
export TARGET=arm-elf-eabi

打造的binutils

下载的binutils源，然后创建一个build目录，并可以建立的binutils没有问题：

build binutils

Downloading a binutils source, then creating a build directory, and could build binutils without an issue:

mkdir build-binutils
cd build-binutils
../binutils-2.24/configure --target=$TARGET --prefix=$PREFIX --with-sysroot --enable-64-bit-bfd --disable-shared --disable-werror --disable-nls
make configure-host
make LDFLAGS="-all-static"
sudo make install

建筑GCC

下载GCC 4.8源代码，并运行构建过程

building gcc

Downloading gcc 4.8 source, and run the build process

mkdir build-gcc
cd build-gcc
../gcc-4.8.3/configure --target=$TARGET --prefix=$PREFIX --disable-nls --enable-languages=c,c++ --without-headers --disable-shared --enable-multilib --with-sysroot --disable-werror
make configure-host
make all-gcc << ERROR
make all-target-libgcc

不过，我得到了无效房源的选项建筑r'`错误。

/usr/local/bin/g++-4.8 -c   -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings   -DHAVE_CONFIG_H -DGENERATOR_FILE -I. -Ibuild -I../../gcc-4.8.3/gcc -I../../gcc-4.8.3/gcc/build -I../../gcc-4.8.3/gcc/../include  -I../../gcc-4.8.3/gcc/../libcpp/include  \
        -o build/genconstants.o ../../gcc-4.8.3/gcc/genconstants.c
Assembler messages:
Fatal error: invalid listing option `r'
make[2]: *** [build/genconstants.o] Error 1
make[1]: *** [all-gcc] Error 2

替代建设进程

我试图用默认的编译器从Mac具有以下配置：

Alternative building process

I tried to use default compiler from Mac with the following configuration:

./contrib/download_prerequisites
CFLAGS="-arch i386 -arch x86_64 -Wno-error=deprecated-declarations -Wno-error=unused-variable -Wno-error=unused-function" ../gcc-4.8.3/configure --target=$TARGET --prefix=$PREFIX --disable-nls --enable-languages=c --without-headers --disable-shared --enable-multilib

然后，它正常工作与让所有海湾合作委员会，但我也有不同的错误使所有目标-libgcc中，所以我会坚持到GCC方法取代铛/ LLVM的做法。

Then, it works fine with make all-gcc, but I also have different error with make all-target-libgcc, so I'll stick to gcc approach instead of clang/llvm approach.

我的猜测是，汇编为苹果有蹊跷的是海湾合作委员会给（因为没有什么错铛/ LLVM）参数。

My guess is that the assembler as from Apple has something wrong with parameters that gcc gives (because there's nothing wrong with clang/llvm).

什么可能是错误的？如何解决这个问题？

What might be wrong? How to solve this issue?

推荐答案

在目录打造-GCC / GCC ，存在一个为来代替调用的/ usr / bin中/为的脚本文件。当我改名为到 as_temp ，然后重新运行，一切正常。
环境变量 AS =的/ usr / bin中/为似乎并没有解决这个问题。

In the directory build-gcc/gcc, there exists an as script file to be invoked instead of the /usr/bin/as. When I renamed as to as_temp, and rerun, everything works fine. The environmental variable AS=/usr/bin/as does not seem to solve this issue.

我需要再修改的 /选择/交叉/ ARM-ELF-EABI / SYS-根/ usr / include目录应该按顺序创建prevent另一个错误信息。

I needed one more modification that /opt/cross/arm-elf-eabi/sys-root/usr/include should be created in order to prevent another error message.

我还发现，本网站是在交叉编译pretty有用Mac OS X的

I also found that this site is pretty useful in cross compilation on Mac OS X.
