I downloaded Rosetta 3.12 linux + binaries and I noticed the the bin folder contained all 0 kb linuxgccrelease files. I have tried to compile Rosetta using the provided SCons version that was provided with Rosetta 3.12 linux + binaries download. I followed the "Compiling Rosetta" instructions from the user guide and executed the command
$ python3 ./scons.py -j 4 mode=release bin
Ubuntu seems execute the command fine without any errors nor warnings. After compilation is completed after some time, I do have a bin file, but all the linuxgccrelease files are 0 kb. I tried again using just the source code download for Rosetta 3.12 and then I tried Rosetta 3.13 linux + binaries, but they were all 0 kb. I am not sure on what I should try next.
I currently have python 3.8.10 (I have also installed python 2.7.18), g++ 8.4.0, gcc 8.4.0, Ubuntu 20.04.4, and Linux 4.4.0.
