I’ll test this out on the official buid and will post those results here.

Just saw this post on iraf.net:
You can find the solution here:

https://iraf.net/forum/viewtopic.php?showtopic=1467939
Which claims to fix the problem. I tested using the linux64 version I just downloaded from http://iraf.noao.edu/ The error was the exact same as with the software I’ve built.

The defaults for darkcombine use ‘ccdtype = “dark”’. With this option darkcombine can’t find any of my images. It seems that this option should be left for the user to specify. I also had to change process from yes to no. Without the change to process I got:
List of dark images to combine (@origList):
ERROR: No bad pixel mask found
“ccdproc (ims, output=””, ccdtype=ccdtype, noproc=no)”
line 37: ccdred$darkcombine.cl
called as: `darkcombine ()
Original parameters after a clean build:
ccdred> lpar darkcombine
input = List of dark images to combine
(output = “Dark”) Output dark image root name
(combine = “average”) Type of combine operation
(reject = “minmax”) Type of rejection
(ccdtype = “dark”) CCD image type to combine
(process = yes) Process images before combining?
(delete = no) Delete input images after combining?
(clobber = no) Clobber existing output image?
(scale = “exposure”) Image scaling
(statsec = “”) Image section for computing statistics
(nlow = 0) minmax: Number of low pixels to reject
(nhigh = 1) minmax: Number of high pixels to reject
(nkeep = 1) Minimum to keep (pos) or maximum to reject (neg
(mclip = yes) Use median in sigma clipping algorithms?
(lsigma = 3.) Lower sigma clipping factor
(hsigma = 3.) Upper sigma clipping factor
(rdnoise = “0.”) ccdclip: CCD readout noise (electrons)
(gain = “1.”) ccdclip: CCD gain (electrons/DN)
(snoise = “0.”) ccdclip: Sensitivity noise (fraction)
(pclip = -0.5) pclip: Percentile clipping parameter
(blank = 0.) Value if there are no pixels
(mode = “ql”)

The latest version (5/25/17) of the code doesn’t work until I set the parameter for process to no.
