<HTML><BODY>Dear wien2k community,<br>I am trying to run the new version of the code on a fresh install of Ubuntu 18.04.2 LTS.<br>It is serial (with OMP) compilation with no libxc, fftw, scalapack, elpa. <br>Since WIEN2k_16 it was more or less Ok to compile the code with gfortran, <br>but with new version there are problems again.<br><br>First, the new 19.1 version does not compile with gfortran (7.4.0) with the error during lapw0 compilation <br>> inputpars.F:664:8:<br>> if(read_vhalf .eq. .true.) then<br>> 1<br>> Error: Logicals at (1) must be compared with .eqv. instead of .eq.<br>If I fix the file in accordance with gfortran rules, it compiles.<br>According to gcc, this is the ifort extension not working on "more standard" implementations.<br><br>Second, when the code is compiled, running simple (GaAs) example which works perfectly<br>at least in WIEN2k 16, 17, 18 gives the error <br>$ init_lapw -b<br>$ run_lapw<br>STOP LAPW0 END<br>STOP SECLR4 - Error<br><br>What possibly may go wrong here? I have no idea how to debug this problem.<br><br>Sincerely yours, <br>Mikhail Nestoklon</BODY></HTML>
