I somehow upgraded GSL from 2.6 to 2.7, then Garfield++ gives error when I compile my application with it (of course). Then I try to reinstall Garfield++, deleted the whole directory and reinstall from the download step. After “cmake DWITH_EXAMPLES=OFF $GARFIELD_HOME”, I got errors when “make” it. Too many errors so I put the first of them. Could someone tell me what is the problem? Thanks in advance!
