好吧，Tomatoware 1.7 已经基于 OpenSSL 1.1.1b 编译，本文可以不看了。
前文有说 Tomatoware 下基于最新的 OpenSSL 1.1.1a/b 编译 Curl 时会遇到 openssl version mismatch 的错误，因为原系统中有 OpenSSL 1.0.2 旧版存在，直接替换系统的 1.0.x 版本到 1.1.1x 有风险，所以当时就用了 WolfSSL。今天用一个丑陋的 Hack 解决了这个问题，反正是编译出了基于 OpenSSL 1.1.1b 的静态执行文件 Curl。
脚本内容如下：
#!/bin/sh
[ -z "$1" ] && echo "Usage: ./openssl-fix fix|restore"
[ "$1" = "fix" ] && {
mv /mmc/lib/libcrypto.a /mmc/lib/libcrypto.a_
mv /mmc/lib/libcrypto.so /mmc/lib/libcrypto.so_
mv /mmc/lib/libssl.a /mmc/lib/libssl.a_
mv /mmc/lib/libssl.so /mmc/lib/libssl.so_
mv /mmc/bin/openssl /mmc/bin/openssl_
ln -s /mmc/src/openssl-1.1.1b/apps/openssl /mmc/bin/openssl
ln -s /mmc/src/openssl-1.1.1b/lib/libcrypto.a /mmc/lib/libcrypto.a
ln -s /mmc/src/openssl-1.1.1b/lib/libssl.a /mmc/lib/libssl.a
}
[ "$1" = "restore" ] && {
rm /mmc/lib/libcrypto.a /mmc/lib/libssl.a
mv /mmc/lib/libcrypto.a_ /mmc/lib/libcrypto.a
mv /mmc/lib/libcrypto.so_ /mmc/lib/libcrypto.so
mv /mmc/lib/libssl.a_ /mmc/lib/libssl.a
mv /mmc/lib/libssl.so_ /mmc/lib/libssl.so
rm /mmc/bin/openssl
mv /mmc/bin/openssl_ /mmc/bin/openssl
}
编译前运行：./openssl-fix fix ; 编译完成后运行：./openssl-fix restore 。
make clean
./configure --prefix=/opt --with-ca-bundle=/opt/etc/ssl/certs/ca-certificates.crt --with-ca-fallback --with-ssl=/mmc/src/openssl-1.1.1b --with-nghttp2 --enable-ares --disable-ldap --disable-shared --without-libpsl --disable-ntlm-wb --disable-ldap --disable-ldaps --disable-dict --disable-ipv6 --without-libssh2 --disable-gopher --without-libidn --without-libidn2 -disable-nls --disable-manual --without-krb4
结果：
