执行步骤"make“时Qt编译错误，-fno-堆栈限制

Question

在编译项目时遇到了一些问题，项目是由学校提供的，即使我不更改任何内容，在Qt中编译时也会出现以下错误：

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: *** [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

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)

有什么可能会出错的想法吗？在Mac上运行

clang编译器不支持‘-fno-堆栈限制’。但是，通过将--stack标志传递给GNU链接器，可以获得相同的效果：

   --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默认链接器，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.

若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 =堆栈大小为16 of。
