I have built this on systems at work, that are populated by CAD guys who have developed a good set of libraries to maintain in a linux distribution.  Went without a hitch. I am trying to build this at home with an opensuse distribution.  I am not trying to do any modifications to python, now or in the future.  I am trying to build this as another software installation wants 3.7 or better and opensuse provided 3.6. I am stuck with a early compile error after the make command.  I have downloaded, built and installed the openSSl.I have changed the ld.so.conf to include the newly built ssl in the list and re-ran ldconfig.  Even though I have added the newly built ssl to the conf file a dump of the ldconfig does not show the locally built ssl libs.  Does this process depend on LD_LIBRARY_PATH ?  Defining LD_LIBRARY_PATH made no discernable difference. kevin@localhost:~/Sources/Python-3.10.5> sudo ldconfig -p | grep ssl [sudo] password for root:          libssl3.so (libc6,x86-64) => /usr/lib64/libssl3.so        libssl.so.1.1 (libc6,x86-64) => /usr/lib64/libssl.so.1.1        libevent_openssl-2.1.so.6 (libc6,x86-64) => /usr/lib64/libevent_openssl-2.1.so.6 The newly built ssl dir:kevin@localhost:~/Sources/Python-3.10.5> ls -lrt /usr/local/ssl total 40 drwxr-xr-x 1 root root    14 Jul 18 15:17 include drwxr-xr-x 1 root root   190 Jul 18 15:17 lib64 drwxr-xr-x 1 root root    30 Jul 18 15:17 bin drwxr-xr-x 1 root root     0 Jul 18 15:17 private drwxr-xr-x 1 root root     0 Jul 18 15:17 certs drwxr-xr-x 1 root root    36 Jul 18 15:17 misc -rw-r--r-- 1 root root 12292 Jul 18 15:17 openssl.cnf.dist -rw-r--r-- 1 root root 12292 Jul 18 15:17 openssl.cnf -rw-r--r-- 1 root root   412 Jul 18 15:17 ct_log_list.cnf.dist -rw-r--r-- 1 root root   412 Jul 18 15:17 ct_log_list.cnf drwxr-xr-x 1 root root    12 Jul 18 15:18 share I see in the web pages the known prerequisites and installed them.kevin@localhost:/usr/local/ssl/lib64> sudo zypper install python310-idle python310-devel python310-curses python310-dbm python310-tk kevin@localhost:/usr/local/ssl/lib64> sudo zypper install build-essential gdb lcov pkg-config       libbz2-dev libffi-dev libgdbm-dev libgdbm-compat-dev liblzma-dev       libncur ses5-dev libreadline6-dev libsqlite3-dev libssl-dev       lzma lzma-dev tk-dev uuid-dev zlib1g-dev I see in the web pages this snip:Python build finished successfully!
