Re: [Scidvspc-users] High memory usage with Stockfish analysis

[Morten S. <mor...@gm...>]

I had 8.6.6, under Debian 9 x64.

I checked what was installed and available, and evidently both 8.5 and 
8.6 are available as separate sets of packages via apt, and both were 
installed, but I guess 8.6 took presedence. Tried to uninstall 8.6 and 
just leave 8.5 (8.5.19 to be specific). Also, /usr/bin/tclsh and 
/usr/bin/wish were symlinks to tclsh8.6 and wish8.6 respectively, so 
after removing everything 8.6 I had to make new symlinks to the 8.5 
binaries manually.

After that SvP configured and compiled just fine, and now running multi 
line analysis now also seems to work fine. Memory usage is rock stable.
