我正在尝试交叉编译汇编hello world
目前，当我运行linux构建时，它显示“exec格式错误：./linuxbuild.out”，错误代码为126，下面显示了objdump中的一些差异。我尝试在链接器和lazy lib上使用-F，但没有成功。转储中的一个差异是缺少__mh_execute_header
我是这么做的
在x86-64 linux上我有这个程序集

$ cat hello.s 
    .global _main
    .align 2

    _main: mov X0, #1
    adr     X1, hello
    mov     X2, #13
    mov     X16, #4
    svc     0

    mov     X0, #0
    mov     X16, #1
    svc     0

    hello: .ascii  "Hello\n"

我写了

clang hello.s --target=arm64-apple-macosx12.5.0 -c -o h.o
ld64.lld h.o -arch arm64 -platform_version macos 12 5 -v -dylib -o linuxbuild.out

输出

LLD 14.0.6
Library search paths:
    /usr/lib
    /usr/local/lib
Framework search paths:
ld64.lld: warning: h.o has version 12.5.0, which is newer than target minimum of 12

你可以看到区别
