Hello everyone,
I'm trying to run a numerical modeling software that requires openmpi extension
files to run, but I'm getting this error: “*/PADCIRC.exe: error while loading
shared libraries: ?: cannot open shared object file: No such file or directory”
I tried looking at the error through another road by running: “cygcheck
*/PADCIRC.exe", and I got these two messages:
“cygcheck: track_down: could not find cygopen-pal-13.dll
cygcheck: track_down: could not find cygopen-rte-12.dll”
I checked the cygwin website and the only .dll availables to install are
cygopen-rte-40.dll and cygopen-rte-40.dll. Does someone know where can I find
the remaining extension files?
It looks like those were probably part of the now unsupported 1.10 releases: if
you rebuild against current libopenmpi-devel and openmpi 4.1 releases, your
software should work with the current cyg...40.dll binaries.
You can research installing ancient openmpi releases still available from the
Cygwin Time Machine:
