gcc - MacOS High Sierra上的链接错误: “Undefined symbols for architecture x86_64” std::__1

我想使用MAD-X(方法化加速器设计； http://madx.web.cern.ch/madx/)的代码。我必须承认我是C，C++，编译等的完全新手。

我将Mad-X git存储库(https://github.com/MethodicalAcceleratorDesign/MAD-X)中的源代码下载到了MacBook Pro(2016年，英特尔)中，并且第一步，我希望在不做任何修改的情况下编译代码。为此，我运行

make madx-macosx64-gnu

在编译过程中会出现一些警告，但链接失败并出现许多错误:

你能给我建议如何编译吗？例如，有几个Makefile，一个用于MacOS，但我不确定如何正确使用它们。

根据乌尔里希·埃克哈特(Ulrich Eckhardt)的评论，我运行了“make -d --trace”，它提供了很多输出，但是不幸的是，对于“ undefined symbol ...”没有什么更确定的结论。

最佳答案

感谢David Hammen的评论及其中的链接:

Link OSX Homebrew Gfortran against libc++

我能够解决此问题:

我在文件中搜索了所有出现的“-lstdc++”，并在以下文件中找到了匹配项:

linker.g95(无需编辑此...)

linker.gfortran:将第44行更改为

LDLIBS + = $(如果$(call eq，$(OSTYPE)，Darwin)，-lgfortran -lstdc++ -lgcc
-lgcc_eh -lSystem -nodefaultlibs，)

到

LDLIBS + = $(如果$(call eq，$(OSTYPE)，Darwin)，-lgfortran -lc++ -lgcc
-lgcc_eh -lSystem -nodefaultlibs，)

Makefile_lib:更改第57和62行(在if子句中检查Darwin = MACOS)，也将-lstdc++替换为-lc++

像苍蝇一样工作:)
