Question

如果我在Mac 10.6中使用-m32标志编译32位可执行文件，例如：

gcc -m32 test.c -o test

在“test”上运行valgrind失败并显示错误：

valgrind：./ test：无法执行二进制文件

是否有任何标志要传递给valgrind来执行此操作？是32位模式下编译valgrind的唯一选择吗？

由于

Answer 1

Blender，-m32标志只是意味着以32位模式编译文件。 Mac 10.6运行32位可执行文件就好了。

Answer 2

我也有这个问题，由MacPorts构建/安装valgrind。然而，当我自己构建它时，问题就消失了。我可以确认没有额外配置选项的valgrind的默认版本支持Snow Leopard上的32位和64位程序（使用的版本为3.6.1。）

Answer 3

你遇到什么版本的Valgrind？

在Linux和MacOS上，单个版本的Valgrind可以自动检测并为32位和64位二进制文件做正确的事情。

以下是我在Mac OS X 10.6.7 (10J869)上看到的内容：

$ echo "int main() { free(1); return 0; }" | gcc -xc - -g -o a.out
$ echo "int main() { free(1); return 0; }" | gcc -xc - -g -o a.out32 -m32
$ valgrind --version
