按照here中的说明尝试为讲稿器创建构建文件夹。
这样做时，我得到一个标志，即“ -mL2 =“，编译器会抱怨该标志未设置。当我尝试将其设置为“ -mL2 =”时，它抱怨说（很可能是）缺少参数。但是我不知道它想要什么。
我在浆粕GCC或GCC-7.1.1中找不到有关此标志的任何信息。知道它做什么的人吗？输出如下：
-- The C compiler identification is GNU 7.1.1
-- The CXX compiler identification is GNU 7.1.1
-- The ASM compiler identification is GNU

编辑1：
发现，如果我仅删除标志和“ -m32”，它将停止抱怨。但是它正在尝试在/opt/pulp-riscv/riscv32-unknown-elf/bin/ld上找到一个名为riscv.ld的目录。问题在于，在/bin的那个位置，链接器文件是ld，而不是在带有文件ld的名为riscv.ld的文件夹中。
