​Hello Knut,

You might be better off using the gcc 4.8 compilers on Ubuntu 18 which you can install with

$ sudo apt-get install gcc-4.8 g++-4.8 gfortran-4.8

Then on your cmake command line you could set those before the actual cmake command.  I've listed some other options you could try as well after the cmake command (apart from whatever other options you may be using).

$ CC=/usr/bin/gcc-4.8  CXX=/usr/bin/g++-4.8  FC=/usr/bin/gfortran-4.8  cmake  -DFS_PACKAGES_DIR=/path_to_the_3rd_packages_after downloading_them  -DCMAKE_INSTALL_PREFIX=/path_to_install_location  -DCMAKE_EXE_LINKER_FLAGS=-Wl,--disable-new-dtags -L/usr/lib/x86_64-linux-gnu -L/usr/local/lib -lz  -DGFORTRAN_LIBRARIES=/usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.so

- R.

Dear Freesurfer exports,

I am unable to launch freeview. I have uncommented qt_setup to be able to start freeview but now it does not start at all. I am sending output from a session where I started it using gdb.

Please look below. I am using the latest version of freeview download from http://www.freesurfer.net/fswiki/UpdateFreeview

 

Best regards
