[esp-r] Re: Recent ESP-r experience on MacOS

[Jon Hand]

Compilers and ESP-r - although the new OS is allowing gcc10 I have found
that ESP-r is rather more stable with gcc8.  If you are using homebrew
on OSX you can install older versions of the compilers in addition to the
default gcc10.  Gcc10 does not like some of the older code constructs
in res where it tries to draw a 3D surface plot.

To get better debug information always include --debug  or --extra-debug
in the Install command line.

An 'end of record' error is a trying to stuff excess characters into a string.
So your path or file name might be overly long.

I have not yet encountered an issue with a zone that starts with an elevation above
zero so that is a puzzle. As a work-around for the non-zero elevation you could start the zone at
zero and then do a transform of the zone to move it into place.

Subject: [esp-r] Recent ESP-r experience on MacOS


Dear all,

I have just attempted an update to release 13.3.11 on my Macs with a rather mixed first experience:

- On my MacOS 10.15.7 ("Catalina") machine, I have been able to compile with macport's gcc5, but not gcc10. Yet, starting prj gives me a segfault (invalid memory reference). On MacOS 10.13.6 ("High Sierra") prj starts fine.

- prj new model creation: When I want to associate images, prj crashes (right after I press "y"):

At line 808 of file folders.F
Fortran runtime error: End of record

Error termination. Backtrace:
#0  0x1448a02ef
#1  0x1448a0baf
#2  0x1448a1212
#3  0x14495ce7d
#4  0x144964fe8
#5  0x14495f108
#6  0x14495f459
#7  0x10ece185a
#8  0x10e877d73
#9  0x10efbb9a6

- When adding a zone based on rectangular plan, setting a non-zero elevation produces warped surfaces (the vertices are not extruded vertically).

I did not do much with the new installation so far, but wanted to share these observations without delay.

Best, Lars.
