[streamFunc]

hi all,
i would like to build this project use centos7 gcc 4..8.5,but report this question:
addr.c:103:7: error: ‘const struct in6_addr’ has no member named ‘s6_addr32’
addr.c:196:35: error: ‘NI_NUMERICSERV’ undeclared (first use in this function)
and so on lots of build question...
and i use ubuntu20.04 build for it is ok.
would this project support centos7 build for it?

support.
You need to upgrade your gcc version to 7 or above,cause this project is based on c++17.

you can follow this to upgrade:
sudo yum install centos-release-scl
sudo yum install devtoolset-8-gcc*
scl enable devtoolset-8 bash
gcc -v

thank you.i follow it to upgrade gcc and solve this question.but another question
certificate.cpp:274:23: error: ‘X509_getm_notBefore’ was not declared in this scope
certificate.cpp:275:23: error: ‘X509_getm_notAfter’ was not declared in this scope

how can i solve this？upgrade openssl version?

[Dw9]

yes。The default openssl version on centos7 is relatively low.

Step 1:upgrade openssl version
$ wget https://www.openssl.org/source/openssl-1.1.1k.tar.gz
$ tar -xvzf openssl-1.1.1k.tar.gz
$ yum install -y zlib zlib-devel perl-CPAN
$ ./config shared --openssldir=/usr/local/openssl --prefix=/usr/local/openssl
$ make && make install
$ echo "/usr/local/lib64/" >> /etc/ld.so.conf
$ echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
$ ldconfig
$ ln -s /usr/local/openssl/bin/openssl /usr/local/bin/openssl

Step 2:Specify the path of openssl
$cmake .. -DOPENSSL_ROOT_DIR=/usr/local/openssl -DOPENSSL_LIBRARIES=/usr/local/openssl/lib
