在x86_64架构下的Arch Linux上交叉编译smartdns时报错

# ./Configure --cross-compile-prefix=mipsel-openwrt-linux- linux-mips32 --prefix=/root/smartdns_mips/openssl --openssldir=/root/smartdns_mips/openssl no-shared no-asm

# make

# make install

成功静态编译openssl-1.1.1g

# export PKG_CONFIG_PATH=/root/smartdns_mips/openssl/lib/pkgconfig

# cd /root/smartdns_mips/smartdns/src

# vi Makefile

...

override CFLAGS +=-Iinclude -I/root/smartdns_mips/openssl/include

...

ifeq ($(STATIC), yes)

override LDFLAGS += -L/root/smartdns_mips/openssl/lib -lssl -lcrypto -Wl,--whole-archive -lpthread -Wl,--no-whole-archive -ldl -static

# cd /root/smartdns_mips/smartdns/package

最后静态编译smartdns

# ./build-pkg.sh --platform openwrt --arch mips_24kc --static

输出信息如下
