这两个命令用来编译release版本的二进制文件
gn gen out/release –args=”is_component_build=false is_debug=false”
ninja -C out/release nginx-1.18.0_ipdb
默认系统头文件和依赖库
build/linux/debian_sid_amd64-sysroot 这个目录相当于根目录, usr/lib和usr/include 分别放了依赖库和头文件
chromium移除了这两个文件,不知道为何, 会导致nginx 编译失败,目前解决办法是从旧版本拷贝过去
build/linux/debian_sid_amd64-sysroot/usr/lib/x86_64-linux-gnu/libcrypt.so
build/linux/debian_sid_amd64-sysroot/usr/include/crypt.h
修改编译参数
build/config/compiler/BUILD.gn, 比如nginx 可能需要把这个特性关掉
if (!is_nacl && !use_libfuzzer) {
#cflags += [ “-Wunreachable-code” ]
}
