本文介绍了在Mac上编译：如果我的编译器未能进行完整性检查，这意味着什么？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图安装一些天文学软件包，特别是cfitsio。使用内置mac gcc / g ++编译器和HPC编译器，我得到以下错误：
configure：错误：C预处理程序/ usr / local / bin / g ++无法进行完整性检查
configure：error：C预处理程序/ usr / bin / g ++无法进行完整性检查
$ / usr / local / bin / g ++ --version
g ++（GCC）4.8.1

$ / usr / bin / g ++ --version
配置：--prefix = / Applications / Xcode.app /目录/ Developer / usr --with-gxx -include-dir = / usr / include / c ++ / 4.2.1
Apple LLVM版本5.0（clang-500.2.79）（基于LLVM 3.3svn）
目标：x86_64-apple-darwin13.0.2
线程模型：posix
查看 config.log code>，正如所暗示的那样，是相当不真实的：
configure：3409：检查如何运行C预处理器
configure：3479：result：/ usr / local / bin / g ++
configure：3499：/ usr / local / bin / g ++ conftest.c
conftest.c：14：8：error：'语法'不命名类型
语法错误
^
我的安装命令看起来像：
CPP = / usr / local / bin / g ++ CXX = / usr / local / bin / g ++ CC = / usr / bin / gcc CFLAGS = - arch x86_64 -g -O2./configure
CPP = / usr / bin / g ++ CXX = / usr / bin / g ++ = - arch x86_64 -g -O2./configure
谷歌搜索迄今没有取得丰硕成果。我错过了什么或做错了什么？ 解答方案
答案由@ n.m标识。在注释中：环境变量 CPP 被错误地设置为指向 g ++ ，这当然不起作用。 cpp 是我系统上C预编译器的名称。
I'm trying to install some astronomy packages, specifically cfitsio. Using both the "built-in" mac gcc/g++ compilers and the HPC compilers, I get the following errors:
configure: error: C preprocessor "/usr/local/bin/g++" fails sanity check
configure: error: C preprocessor "/usr/bin/g++" fails sanity check
$ /usr/local/bin/g++ --version
g++ (GCC) 4.8.1

$ /usr/bin/g++ --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.2
Thread model: posix
Looking at config.log, as suggested, is rather unrevealing:
configure:3409: checking how to run the C preprocessor
configure:3479: result: /usr/local/bin/g++
configure:3499: /usr/local/bin/g++ conftest.c
conftest.c:14:8: error: 'Syntax' does not name a type
Syntax error
^
My install commands look like:
CPP=/usr/local/bin/g++ CXX=/usr/local/bin/g++ CC=/usr/local/bin/gcc CFLAGS="-arch x86_64 -g -O2" ./configure
CPP=/usr/bin/g++ CXX=/usr/bin/g++ CC=/usr/bin/gcc CFLAGS="-arch x86_64 -g -O2" ./configure
Googling has so far yielded no fruitful results. What am I missing or doing wrong?
解决方案
The answer was identified by @n.m. in the comments: The environmental variable CPP was incorrectly set to point to g++, which of course will not work. cpp is the name of the C precompiler on my system.
