Python3.10 compilation and installation report SSL failure solution

1. Upgrade openssl version - compile and install

Download the OpenSSL file from the official website

https://www.openssl.org/source/openssl-1.1.1n.tar.gz

2. Unzip and compile after downloading

cd software
tar -zxvf openssl-1.1.1n.tar.gz
cd openssl-1.1.1n
 
./config --prefix=/usr/local/openssl   
make 
make install

3. Modify the link file

备份原有链接
mv /usr/bin/openssl /usr/bin/openssl.bak

创建软链接
ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl

4. Add the path to ld.so.conf

Note: There is no "/" at the end of the path, otherwise an error will be reported

echo "/usr/local/openssl/lib" >> /etc/ld.so.conf

5. The settings take effect

ldconfig -v

6. View the OpenSSL version

openssl version
OpenSSL 1.1.1n  15 Mar 2022

7. Pay attention! Notice! Notice! There are 2 methods here:

1、

Modify the Module/Setup link of the Python compiled source file as follows:

The path on line 211 is changed to the path compiled by OpenSSL,

Pages 212-214 uncommented.

as follows:

210  socket line above, and edit the OPENSSL variable:
211  OPENSSL=/usr/local/openssl
212  _ssl _ssl.c \
213      -I$(OPENSSL)/include -L$(OPENSSL)/lib \
214      -lssl -lcrypto

Note: Everyone's file may be different, please refer to your own.

Recompile the Python source file after modification.

./configure --prefix=/usr/local/python310
make && make install

2. Use parameters with ssl during installation

./configure --prefix=/usr/local/python3.10 --with-openssl=/usr/local/openssl --with-openssl-rpath=auto

make && make install
