Question

我们的嵌入式系统使用旧的gcc-gcc版本3.4.4

当我为它编译valgrind 3.9时，我发现了一些错误。我一个接一个地处理它们，但是对于最后一个链接错误，我无法处理它：

memcheck_mips32_linux-mc_leakcheck.o: In function `find_chunk_for':
/storage/source/valgrind-3.9.0/memcheck/mc_leakcheck.c:287: relocation truncated to fit: R_MIPS_HI16 against `_gp_disp'

我尝试添加-G4选项以重新编译，但失败了：

./configure --host=mips-linux --prefix=/storage/source/valgrind-3.9.0/valgrind_install CFLAGS="-G4"

配置将失败并显示：

****configure: WARNING: if you wanted to set the --build type, don't use --host.

configure: error: in `/storage/source/valgrind-3.9.0':

我甚至尝试修改生成Makefile并向C_FLAGS添加-G4选项，但它不起作用。我仍然无法使用-G4选项编译文件。

我不知道-G4选项是否可以解决此链接错误。如果是，我该怎么办？
还有其他方法可以让valgrind与我的工具链一起使用吗？

我无法将此工具链更改为更新版本，因为它与整个系统绑定。

使用旧的MIPS gcc编译valgrind
