C ++ 11在代码块中的编译问题 [英] C++11 compilation issues in codeblocks
本文介绍了C ++ 11在代码块中的编译问题的处理方法，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
我似乎无法获得代码块13.12在clang ++和g ++中正确编译c ++ 11。我在使用clang ++编译时附加了-std = c ++ 11和-stdlib = libc ++。这导致链接错误。对于g ++，当添加-std = c ++ 11或-std = c ++ 0x时，编译器无法找到随机头。当我使用clang ++和g ++在终端中手动编译代码时，没有发生这些错误。
完整的链接器错误太长，从-v调用给出的信息。
在使用clang ++的代码块中使用-std = c ++ 11和-stdlib = libc ++：

不幸的是我不能在终端中比较代码块g ++和g ++。
但是基于两个不同的编译在。。看来代码块在链接步骤期间不使用libc ++库。你怎么代码块使用正确的库上链接的铿锵++？
我假设基础上，铿锵问题G ++中的代码块甚至告诉时使用旧的C ++ 03库编译器切换到c ++ 11。但我不知道如何确认这一点。
解决方案我发现clang ++的答案。
显然，你必须将-stdlib = libc ++添加为编译器标志和链接标志。

发生g ++问题的原因是，即使codeblocks输出它是编译g ++实际上使用clang ++库作为编译和链接过程的一部分。虽然基于输出不是100％清楚如果g ++编译器及其包括被调用。要解决这个问题，您需要为编译和链接添加-stdlib = libc ++标志。为了证明对苹果的代码块使用引擎盖下铛库其实，我附上链接和编译和代码块中使用的命令期间-v的输出。

经过很多烦恼后，我终于找出了g ++对代码块的问题。问题是，调用g ++时，代码块不使用可执行路径。相反，它在编译器设置中使用您的工具链可执行路径。我的工具链可执行文件路径设置为/ usr / bin，g ++的apple版本位于该目录。这个版本实际上通过一系列复杂的调用调用clang ++。所有我需要做的来解决这个问题是将工具链可执行文件路径更改为/ usr / local / bin，其中我的实际gnu编译器驻留。在这个更改后，我能够摆脱-stdlib = libc ++，我的编译和链接读数如下。
编译：

I cant seem to get codeblocks 13.12 to compile c++11 correctly in both clang++ and g++. I have attached the -std=c++11 and -stdlib=libc++ when compiling with clang++. This leads to a linking error. For g++ when you add -std=c++11 or -std=c++0x, the compiler cannot find the random header. When I compiled the code manually in a terminal using both clang++ and g++, none of these errors occurred.
The full linker errors are too long to post so i will just post the information given from the -v invocation. In codeblocks using clang++ with -std=c++11 and -stdlib=libc++:

But based on the output from the two different compilations in clang. It appears codeblocks is not using the libc++ library during the linking step. How do you get codeblocks to use the correct libraries on linking for clang++?
I assume based on the clang problem g++ in codeblocks is using an older c++ 03 library even when telling the compiler to switch to c++11. But unfortunately I dont know how to confirm this.
解决方案I found the answer to clang++.
Apparently you have to add -stdlib=libc++ as both a compiler flag and a linking flag.
The linkage output turns to
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) Target: x86_64-apple-darwin12.5.0 Thread model: posix "/usr/bin/ld" -demangle -dynamic -arch x86_64 -macosx_version_min 10.8.0 -o bin/Release/p_class_test obj/Release/Thread_Pool/thread_helper.o obj/Release/Thread_Pool/thread_pool.o obj/Release/Desktop/kmap_testing/hash_methods.o obj/Release/Desktop/p_class_test/p_classtest.o obj/Release/Desktop/p_class_test/refmanager.o -lc++ -lSystem /usr/bin/../lib/clang/5.1/lib/darwin/libclang_rt.osx.awhich clearly shows the correct library being used.
The g++ problem occurs because even though codeblocks outputs that is it compiling with g++ in actually it using clang++ libraries as part of the compilation and linking process. Though based on the output its not 100% clear if the g++ compiler and its includes are being called. To fix the problem, you need to add -stdlib=libc++ flag for both compilation and linking. As proof that codeblocks on apple is in fact using the clang libraries under the hood, I have attached the output from -v during both linking and compiling and the commands used by codeblocks.

The problem is that codeblocks when calling g++ does not use your executable path. Instead it uses your toolchain executable path in the Compiler settings. My toolchain executable path was set to /usr/bin where the apple version of g++ resides. This version actually calls clang++ through a complex series of calls. All I needed to do to fix the issue was to change the toolchain executable path to /usr/local/bin where my actual gnu compiler resides. After this change, I was able to get rid of -stdlib=libc++ and my compilation and linking readouts are below.
