Executable not running when libgfortran3 not available

[juliombarros]

Hi, Similar to this previous issue, the executable file did could not be called in the absence of libgfortran3. However, on newer ubuntu versions, libgfortran3 is not available.

create_trajectory_model() %>%
  add_trajectory_params(
    lat = 43.45,
    lon = -79.70,
    height = 50,
    duration = 6,
    days = "2015-07-01",
    daily_hours = c(0, 12),
    direction = "backward",
    met_type = "reanalysis",
    met_dir = '/opt/hysplit.v5.0.0_Ubuntu/met',
    exec_dir = '/opt/hysplit.v5.0.0_Ubuntu/exec'
  ) %>%
  run_model()

As a result, I would get the following empty output plus a warning message:

A tibble: 0 x 12
 … with 12 variables: run <int>, receptor <int>, hour_along <int>,
   traj_dt <dttm>, lat <dbl>, lon <dbl>, height <dbl>, traj_dt_i <dttm>,
   lat_i <dbl>, lon_i <dbl>, height_i <dbl>, pressure <dbl>

...
Warning messages:
1: In system(sys_cmd) : error in running command
2: In system(sys_cmd) : error in running command
3: In file.copy(from = file.path(exec_dir, trajectory_files), to = recep_file_path,  :
  problem copying /opt/hysplit.v5.0.0_Ubuntu/exec/traj--bwd-15-07-01-00-1lat_43p45_lon_-79p7-hgt_50-              6h to /opt/hysplit.v5.0.0_Ubuntu/exec/1/traj-2021-03-18-14-37-15/traj--bwd-15-07-01-00-1lat_43p45_lo              n_-79p7-hgt_50-6h: No such file or directory

The solution: Ubuntu users might find useful this workaround on how to install libgfortran3 on new versions of the OS.

I got this problem on LINUX CentOS 8 so How to fix this problem?
