我正在 Windows 10 下的基于 Intel 的 Linux Ubuntu 系统上为 QNX 6.5.0 下的 Intel i486 进行交叉编译。其中一个库是 snappy，v.1.0.4。将 i486-pc-nto-qnx6.5.0* 工具（gcc、g++、ld 等）从 QNX 系统复制到 Ubuntu 中的 /usr/local/bin。然后配置为./configure --build=x86_64-pc-linux-gnu --host=i486-pc-nto-qnx6.5.0。运行make，报错：C compiler can't create executables when cross-compiles.
在 config.log 中：
