c++ - 执行步骤 “make”和-fno-stack-limit时，Qt Creator编译错误

Question

在编译项目时遇到一些问题，该项目是由学校提供的，即使我不做任何更改，在Qt Creator中进行编译时也会遇到这些错误:

clang: error: unknown argument: '-fno-stack-limit'
clang: error: unknown argument: '-fno-stack-limit'
clang: error: unknown argument: '-fno-stack-limit'
clang: error: unknown argument: '-fno-stack-limit'
make: clang: error: unknown argument: '-fno-stack-limit'
*** [adapter.o] Error 1
make: *** Waiting for unfinished jobs....
clang: error: unknown argument: '-fno-stack-limit'
make: *** [trailblazer.o] Error 1
make: *** [types.o] Error 1
make: *** [trailblazergui.o] Error 1
make: *** [BasicGraph.o] Error 1
clang: error: unknown argument: '-fno-stack-limit'
make: *** [console.o] Error 1
clang: error: unknown argument: '-fno-stack-limit'
make: *** [costs.o] Error 1
make: *** [direction.o] Error 1
22:27:18: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project Trailblazer (kit: Desktop Qt 5.13.0 clang 64bit)

有什么想法可能有问题吗？
在Mac OS上运行

clang编译器不支持'-fno-stack-limit'。但是您可以通过将--stack标志传递给GNU链接器来获得相同的效果:

   --stack reserve
   --stack reserve,commit
       Specify the number of bytes of memory to reserve (and optionally commit) to be used as stack for this program.  The default is 2MB
       reserved, 4K committed.  [This option is specific to the i386 PE targeted port of the linker]

对于Mac OS的默认链接器，您可以传递 -stack_size:

-stack_size size
    Specifies the maximum stack size for the main thread in a program. Without this
    option a program has a 8MB stack. The argument size is a hexadecimal number with
    an optional leading 0x. The size should be an even multiple of 4KB, that is the
    last three hexadecimal digits should be zero.

要将标志传递给链接器，可以使用 -Wl。例如。，

clang++ -Wl,-stack_size -Wl,0x1000000 -o test test.cpp

其中0x1000000 =堆栈大小16MB。
