Hello all! I apologize if this is posted in the wrong place. I am attempting to compile OpenSSL 1.1.od so that I can eventually install Apache 2.4.25. I have run the " ./Configure solaris64-sparcv9-gcc" and followed up with the "make". During the "make" process I see "gcc: unrecognized option `-pthread'" at the end of each command-line processed. (see below) I should tell y'all that this is a Solaris 10 OS on a Sun server. The version of GCC that is installed is GCC 3.4.3 (also below). My question is -- Will upgrading to the newest version of GCC correct these errors? If not -- do you have any suggestions on how to correct them? Thanks & have a wonderful weekend!
