【已解决】【TuyaOS SDK】用libtuyaos.a中自带的mbedtls, 链接时报错

[19926824531]

你好，我这边编译了一个基于mbedtls的 libcurl.a，链接时发现缺少以下的几个接口，请问SDK是去掉了哪些mbedtls特性呢？
这个冲突问题应该如何解决呢？

这个是我这边编译curl时的配置：

./configure --prefix=$(pwd)/build_lib --host=mips-linux-uclibc CC=mips-linux-uclibc-gcc CXX=mips-linux-uclibc-g++ --enable-shared=no --enable-static=yes --enable-optimize --disable-telnet --disable-largefile --disable-ftp --disable-smtp --disable-imap --without-libssh2 --without-zlib --without-librtmp --without-libidn --without-gnutls --disable-ldap --disable-ldaps --disable-pop3 --disable-netrc --disable-mime --disable-socketpair --disable-debug --disable-curldebug --disable-symbol-hiding --disable-dict --disable-rtsp --disable-gopher --disable-file --disable-tftp --disable-manual --disable-sspi --disable-ntlm-wb --disable-tls-srp --disable-soname-bump --disable-manual --disable-smb --disable-smbs --disable-unix-sockets --disable-ipv6 --disable-mqtt CFLAGS="-march=mips32r2 -muclibc" --with-mbedtls=/vm_disk/Code/D2PT_Compare/09_T23N_D2PT/Cam/dependence/mbedtls

1）可以看一下libtuyaos.a库的符号表，有些mbedtls接口还是有的，是不是链接顺序问题
2）是什么业务场景你们还需要集成自己的http等服务

[19926824531]

（1）这些报 "未定义引用" 的符号表 libtuyaos.a中没有的

root@ubuntu:/vm_disk/Code/D2PT_Compare/09_T23N_D2PT/Cam/dependence/tuya/lib# ls
libtuyaos.a
root@ubuntu:/vm_disk/Code/D2PT_Compare/09_T23N_D2PT/Cam/dependence/tuya/lib# grep -Rn "mbedtls_x509_crt_parse_path"
root@ubuntu:/vm_disk/Code/D2PT_Compare/09_T23N_D2PT/Cam/dependence/tuya/lib#

（2）厂测模式下会用到 http服务

[pippin-bobo]

请问产测什么场景会使用http，如果对接涂鸦服务，建议使用使用涂鸦的产测协议
