[esp-r] Re: ESP-r 11.6 and Radiance in Cygwin

[Jon Hand]

One of the Radiance related packages that ESP-r uses during
some assessments driven by the e2r module is a package called
gendaylit.  This does the Perez sky model.

I found that the package that I had downloaded from the Radiance site
some time ago needed to be patched to reflect the location (/usr/local/bin) where Radiance
tends to be installed on Linux and OSX and Cygwin boxes.  There
is also a small patch for a clash in a macro name which happens on
some computers.

I have compiled this on OSX under GCC as well as on Ubuntu 8.04 with
no errors. It should probably work on Cygwin.  If someone wants this
tar file with the patches I can send it to you.

It might be worth considering whether we should include this on
the ESRU download page under a helpers section or even to add it
into the subversion repository.

Dear Christian

there does seem to be a bug in the current ESP-r version. The path to /rad
subdirectory is hard-coded to ../rad. If you start ESP-r in the /cfg
subdirectory, it should work (at least it does for me). Starting ESP-r in
any other directory leads to the error messages you gave.

Hello ESP-r community

I am trying to use ESP-r/Radiance. I have tried ESP-r/Radiance from the
Learnix boot-CD (version 11.5) and it works ok. However when I use version
11.6 in Cygwin, install precompiled Radiance from Bozzograo.net and set my
PATH, ESP-r is unable to generate the sky description file giving me a
number of errors like 'no such file or directory', hence obstructing any
visualization. Obviously something is not placed in or does not point to the
right directory. The visualization module has been changed from version 11.5
to 11.6, so maybe it's a glitch introduced in 11.6 or is there another
explanation? Radiance works flawlessly.
