执行二进制文件时出现“无此文件或目录”错误
薛元忠
问题内容：
问题答案：
我在Ubuntu 9.10 x86_64上安装了二进制Linux应用程序。该应用程序附带了旧版本的gzip（1.2.4），该版本已针对较旧的内核进行了编译：
$ file gzip
gzip: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.0.0, stripped
我无法执行该程序。如果我尝试过，就会发生这种情况：
$ ./gzip
-bash: ./gzip: No such file or directory
ldd同样对此二进制文件不满意：
$ ldd gzip
not a dynamic executable
我很好奇：此问题最可能的根源是什么？文件损坏了吗？还是由于为较旧的{kernel，libc，…}构建而导致二进制不兼容？
Per nos的建议，这是的输出strace ./gzip：
execve("./gzip", ["./gzip"], [/* 24 vars */]) = -1 ENOENT (No such file or directory)
dup(2) = 3
fcntl(3, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 10), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa8c9eee000
lseek(3, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(3, "strace: exec: No such file or di"..., 40strace: exec: No such file or directory
) = 40
close(3) = 0
munmap(0x7fa8c9eee000, 4096) = 0
exit_group(1) = ?
这是的输出readelf -a ./gzip：
