I had recently upgraded TQSL from 2.0.3 to 2.3.1 and I was getting this odd error:
tqsl: symbol lookup error: tqsl: undefined symbol: tQSL_ImportSerial
After much hair pulling and teeth gnashing, I discovered that I needed to compile TQSL with the “static library” option instead of dynamically generating the library using the “-DTQSLLIB_STATIC=YES” modifier when calling cmake. Lo and behold, TQSL works fine now. I had to get a new security certificate since I recently put a fresh install of Slackware 64 14.2 stable on my laptop. I’ll try this on the shack computer to make sure it works.
