[Radiance-general] Question about dctimestep

[Zhe Kong]

Dear Radiance Users:
I am struggling with 3-phase method and run into an issue about dctimestep.
At the last step of the tutorial (
https://andymcneil.gitbooks.io/three-phase-method-tutorial/content/35_matrix_multiplication.html)
to use dctimestep to calculate illuminance for three shading systems:

$dctimestep results/photocells.vmx data/Clear.xml results/south.dmx
skies/12_21_15.skv rcalc -e '$1=179*($1*0.265+$2*0.670+$3*0.065)' >
results/illum_122115_clear.dat

At first I received the feedback below:

Usage: dctimestep [-n nsteps][-o ospec][-i{f|d|h}][-o{f|d}] DCspec [skyf]

or: dctimestep [-n nsteps][-o ospec][-i{f|d|h}][-o{f|d}] Vspec Tbsdf
Dmat.dat [skyf]

 I think my dctimestep is not the newest one, so I download it from
http://www.radiance-online.org/cgi-bin/viewcvs.cgi/ray/src/util/dctimestep.c?annotate=2.37

My question is how to install it appropriate. I saved the file as
dctimestep and use $chmod a=r+w+x dctimestep, I got the errors as below:

/Users/zhekong/Radiance/usr/local/radiance/bin/dctimestep: line 2: static:
command not found

/Users/zhekong/Radiance/usr/local/radiance/bin/dctimestep: line 4:
/Applications: is a directory

/Users/zhekong/Radiance/usr/local/radiance/bin/dctimestep: line 5:
apply_overcast.bash: command not found

/Users/zhekong/Radiance/usr/local/radiance/bin/dctimestep: line 6:
apply_overcast.bash: command not found

/Users/zhekong/Radiance/usr/local/radiance/bin/dctimestep: line 7:
apply_overcast.bash: command not found

/Users/zhekong/Radiance/usr/local/radiance/bin/dctimestep: line 8: data/:
is a directory

and so on. The list is a bit long to include all. I don't think I install
it right. Could someone let me know how to replace dctimestep correctly, if
this is the problem, or what is the solution to make this step work?

Thank you very much in advance.
