[英]How to compile Xeon phi patched gcc from source?
I downloaded the MPSS software stack version 3.5.2 source code from the intel website. 我从英特尔网站下载了MPSS软件堆栈3.5.2版源代码。 I am trying to compile the xeon phi ported GCC (ported from GCC 4.7.0) from source and install it in a local subdirectory.
我正在尝试从源代码编译Xeon phi移植的GCC(从GCC 4.7.0移植)并将其安装在本地子目录中。 However, I am getting the following error-
但是,我收到以下错误-
k1om-mpss-linux-gcc -dumpspecs > tmp-specs
/bin/sh: k1om-mpss-linux-gcc: command not found
My configuration is as follows- 我的配置如下-
# The below directory contains the cross compiled libs
# like assembler and linker
export PATH=$HOME/xeon-phi-gcc/bin
# The configure command
../xeon-phi-gcc/configure \
--build=x86_64-linux \
--host=x86_64-mpsssdk-linux \
--target=k1om-mpss-linux \
--prefix=$HOME/cross-gcc \
--enable-languages=c,c++ \
--with-sysroot=/opt/mpss/3.5.1/sysroots/k1om-mpss-linux \
--disable-multilib
# Compiling
make
Why is the Makefile calling k1om-mpss-linux-gcc
? 为什么Makefile调用
k1om-mpss-linux-gcc
? Shouldn't this be the cross compiled gcc binary after make completes ? 这不应该是make完成后交叉编译的gcc二进制文件吗? How can I fix this or what am I missing ?
我该如何解决这个问题或缺少什么?
EDIT 1: I changed the config parameters to --build=x86_64-mpsssdk-linux --host=x86_64-mpsssdk-linux
. 编辑1:我将config参数更改为
--build=x86_64-mpsssdk-linux --host=x86_64-mpsssdk-linux
。 I get the following errors now- 我现在收到以下错误-

EDIT 2: I am now getting the error- 编辑2:我现在收到错误-
/tmp/cc4aDvmI.s: Assembler messages:

/tmp/cc4aDvmI.s:258: Error: no such instruction: `vpackstorelq %zmm0,(%rsp){%k2}'
How can I fix this ? 我怎样才能解决这个问题 ? These seem to be vector instructions but I thought that the gcc cross compiler didn't support vector instructions.
这些似乎是矢量指令,但我认为gcc交叉编译器不支持矢量指令。
Your --build
, --host
and --target
machine are all different (this is referenced as canadian compile, which is slightly different from cross compile, where --build
and --host
are the same). 您的
--build
,-- --host
和--target
机器都不同(这被称为加拿大编译,这与交叉编译( --build
和--host
相同)略有不同)。 This means that an additional compiler is needed to build target libraries. 这意味着需要额外的编译器来构建目标库。
From GCC docs (6.1): 从GCC文档(6.1):
If build and host are different, you must have already built and installed a cross compiler that will be used to build the target libraries (if you configured with --target=foo-bar, this compiler will be called foo-bar-gcc).
如果构建和宿主不同,则必须已经构建并安装了将用于构建目标库的交叉编译器(如果使用--target = foo-bar配置,则该编译器将称为foo-bar-gcc) 。
So, as your --target
is k1om-mpss-linux
, you need that version of compiler in order to build GCC. 因此,由于您的
--target
是k1om-mpss-linux
,因此需要该版本的编译器才能构建GCC。
The result will be a GCC compiled on a --build
machine that will run on a --host
machine and that will produce code that can run on a --target
machine. 结果将是在
--build
机器上编译的GCC,该机器将在--host
机器上运行,并生成可在--target
机器上运行的代码。
