c++ - 如何使用交叉链接器而不是 native 链接器

Question

我正在尝试使用 OpenWRT 提供的工具链为 MIPS 架构交叉编译一个包。我在制作过程中遇到以下错误:

/usr/bin/ld: skipping incompatible /home/user/package/zlib/zlib-1.2.8/libz.so when searching for -lz

在这种情况下，zlib 已经针对 MIPS 进行了交叉编译，但 make 使用的是“/usr/bin/ld”而不是“mipsel-openwrt-linux-ld”。我试过 ./configure 与 --with-ld 选项，但它说 '--with-ld' 是未知选项。

您是否检查了以下页面，https://wiki.openwrt.org/doc/devel/crosscompile ？

Pass the host and build to the build system of the package to trigger cross-compile

For GNU configure, use --build=architecture-unkown-linux-gnu --host=architecture-openwrt-linux-uclibc (for example: ./configure --build=x86_64-unkown-linux-gnu –host=mips-openwrt-linux-uclibc)

Run ./config.guess to get the --build= option.

Check the output and ensure that 'checking whether we are cross compiling… yes' is yes.

For GNU make, override the CC and LD environment variables (usually not needed if GNU configure was used)

make CC=architecture-openwrt-linux-uclibc-gcc LD=architecture-openwrt-linux-uclibc-ld
