如何解决如何为 STL 制作 C++ 编译器支持模板?
我正在尝试使用 hpctoolkit
安装 Spack
。为了做到这一点,我执行了:
git clone https://github.com/spack/spack.git
cd spack/share/spack
source setup-env.sh
spack fetch -D hpctoolkit
spack install hpctoolkit
我无法执行最后一条命令,因为出现以下错误:
Error: ProcessError: Command exited with status 1:
'./bootstrap.sh' '--prefix=/home/hakim/spack/opt/spack/linux-ubuntu20.04-haswell/gcc-10.2.0/boost-1.76.0-oc2u6jxritfsbci4xkhr5lov3i4o4riq' '--with-toolset=gcc' '--with-libraries=serialization,atomic,log,exception,regex,math,random,program_options,wave,iostreams,chrono,system,test,graph,locale,timer,filesystem,date_time,thread' '--without-icu'
它建议我通过显示以下消息来查看构建日志:
See build log for details:
/tmp/hakim/spack-stage/spack-stage-boost-1.76.0-oc2u6jxritfsbci4xkhr5lov3i4o4riq/spack-build-out.txt
A C++11 capable compiler is required for building the B2 engine.
Toolset 'gcc' does not appear to support C++11.
> g++ -x c++ -std=c++11 check_cxx11.cpp
ERROR: Compiler 'gcc@9.3.0' does not support compiling C++ programs.
为了显示编译器,我使用了命令:
spack compiler list
结果是:
==> Available compilers
-- clang ubuntu20.04-x86_64 -------------------------------------
clang@10.0.0 clang@7.0.1
-- gcc ubuntu20.04-x86_64 ---------------------------------------
gcc@9.3.0 gcc@7.5.0
为了摆脱'gcc@9.3.0'版本,我修改了compilers.yaml,它是一个单独的文件,用于存储有关可用编译器的信息。
就我而言,我做到了:
cd ~/.spack/linux
emacs compilers.yaml &
发现(我只显示与gcc编译器相关的部分):
compilers:
- compiler:
spec: gcc@7.5.0
paths:
cc: /usr/bin/gcc-7
cxx: null
f77: /usr/bin/gfortran-7
fc: /usr/bin/gfortran-7
flags: {}
operating_system: ubuntu20.04
target: x86_64
modules: []
environment: {}
extra_rpaths: []
- compiler:
spec: gcc@9.3.0
paths:
cc: /usr/bin/gcc-9
cxx: null
f77: /usr/bin/gfortran-9
fc: /usr/bin/gfortran-9
flags: {}
operating_system: ubuntu20.04
target: x86_64
modules: []
environment: {}
extra_rpaths: []
为了去掉gcc@9.3.0,我把它的部分删了。我现在验证编译器列表,我应该找到:
-- clang ubuntu20.04-x86_64 -------------------------------------
clang@10.0.0 clang@7.0.1
-- gcc ubuntu20.04-x86_64 ---------------------------------------
gcc@7.5.0
现在,当我执行命令时:
spack install hpctoolkit
错误是不同的。我明白了:
=> Error: CompilerAccessError: Compiler 'gcc@7.5.0' has executables that are missing or are not executable: ['/usr/bin/gfortran-7','/usr/bin/gfortran-7']
/home/hakim/spack/lib/spack/spack/build_environment.py:937,in _setup_pkg_and_run:
934 tb_string = traceback.format_exc()
935
936 # build up some context from the offending package so we can
>> 937 # show that,too.
938 package_context = get_package_context(tb)
939
940 logfile = None
==> Error: hpctoolkit-2021.05.15-jkofhcw73pap6ciacwcv2mtcv6uf3n2e: Package was not installed
==> Error: Installation request Failed. Refer to reported errors for failing package(s).
我认为 gcc@7.5.0 编译器安装错误,因为他告诉我它有缺少或不可执行的可执行文件。
我尝试过 gcc@7.5.0、gcc@9.3.0 和 gcc@10.2.0 但没有成功..(我想提一下所有编译器都安装在 /usr/bin
中)
有什么帮助吗?
解决方法
为了修复这个错误,你应该精确地找到 g++ 的路径。 就我而言,这是我的 compilers.yaml 文件的更新内容:
compilers:
- compiler:
spec: gcc@7.5.0
paths:
cc: /usr/bin/gcc-7
cxx: null
f77: /usr/bin/gfortran-7
fc: /usr/bin/gfortran-7
flags: {}
operating_system: ubuntu20.04
target: x86_64
modules: []
environment: {}
extra_rpaths: []
- compiler:
spec: gcc@9.3.0
paths:
cc: /usr/bin/gcc-9
cxx: /usr/bin/g++-9
f77: /usr/bin/gfortran-9
fc: /usr/bin/gfortran-9
flags: {}
operating_system: ubuntu20.04
target: x86_64
modules: []
environment: {}
extra_rpaths: []
现在,它应该可以完美运行了。
