Question

我试图为MIPS架构交叉编译valgrind但是我遇到了错误。

$ make

我不知道-mips32参数是否存在问题，但是如果我将其删除，我会在以后遇到“不支持操作码”的错误。我不确定这个错误是否会引发不合规问题。

我找到同样的问题，下面是解决方案。将-march = mips32更改为--march = mips32r2。我使用了我的构建脚本 -

if [[ "$PATH" == *"/usr/local/mips-2012.09/bin"* ]]; then
echo codesourcery toolchain path is already in PATH var
else
export PATH="/usr/local/mips-2012.09/bin:$PATH"
echo added codesourcery toolchain path to PATH var
fi

export AR=mips-linux-gnu-ar
export CC='mips-linux-gnu-gcc -EL'
export CXX='mips-linux-gnu-g++ -EL'
export LINK='mips-linux-gnu-g++ -EL'
export RANLIB=mips-linux-gnu-ranlib
export CFLAGS='-march=mips32r2'
export CCFLAGS='-march=mips32r2'
export CXXFLAGS='-march=mips32r2'
