從零開始 Nginx 交叉編譯

交叉編譯工具鏈： arm-poky-linux-gnueabi-gcc 

 

./configure --prefix=/home/chad/Documents/nginx_cr  --with-cc=arm-poky-linux-gnueabi-gcc

出現如下的問題

root@ubuntu:/home/chad/Downloads/nginx-1.18.0# ./configure --prefix=/home/chad/Documents/nginx_cr  --with-cc=arm-poky-linux-gnueabi-gcc
checking for OS
 + Linux 4.15.0-101-generic x86_64
checking for C compiler ... not found

./configure: error: C compiler arm-poky-linux-gnueabi-gcc is not found

解決辦法，在configure的時候加上--without-http_upstream_zone_module

src/os/unix/ngx_errno.c: In function 'ngx_strerror':
src/os/unix/ngx_errno.c:37:31: error: 'NGX_SYS_NERR' undeclared (first use in this function)
     msg = ((ngx_uint_t) err < NGX_SYS_NERR) ? &ngx_sys_errlist[err]:
                               ^

出錯的原因仍然是因爲交叉編譯程序無法本地運行，導致NGX_SYS_NERR宏沒有賦值。解決辦法，手動編輯 objs/ngx_auto_config.h，加上

#ifndef NGX_SYS_NERR
#define NGX_SYS_NERR  132
#endif
