Hello - I am trying to install Peter Stetson's standalone DAOPHOT program, which links to some of the IRAF libraries. In order to allow DAOPHOT to read in large images, I need to have rather large array sizes which appear to be over the standard limit. I am able to compile the DAOPHOT code without problems (using additional memory allocation flags), but the .o files will not link to the pre-built IRAF libraries such as libimfort.a.
I suspect that I need to recompile the relevant IRAF libraries using similar large memory allocation flags. Are there instructions somewhere for how to do this?
Here is how I am doing the compilation:
PHP Formatted Code
$ make -f Makefile .fock allstar
gfortran -c -O2 -m64 -mcmodel =large allstar .f
gfortran -c -O2 -m64 -mcmodel =large allstsubs .f
gfortran -c -O2 -m64 -mcmodel =large lnxsubs .f
gfortran -c -O2 -m64 -mcmodel =large iosubs .f
gfortran -c -O2 -m64 -mcmodel =large mathsubs .f
mathsubs .f :1931.72:
IF ((J .GT . 97) .OR . (J .LT . 1)) PAUSE
1
Warning : Deleted feature : PAUSE statement at (1)
gfortran -c -O2 -m64 -mcmodel =large bothsubs .f
gfortran -O2 -Wall -Wsurprising --defsym ,mem_ =0 -fbounds -check -m64 -malloc -cc -mcmodel =large -mlarge -data -threshold -o allstar allstar .o allstsubs .o \

I think the real error is coming from the use of the Mem common in the system, i.e. the compiler is treating the 'mem_' as an array with a base address of zero (from the --defsym,mem_=0' flag) and trying to load it in the base static segment.
We don't really have a document for how to build the system using a new compiler and since it is infinitely faster for me to do it rather than explain it here, I've done just that and put the new binaries at
ftp://iraf.noao.edu/pub/fitz/iraf2161-gfortran-linux64.tar.gz
This is just a tarball of the various 'bin.linux64' directories where all sources were compiled using GFORTRAN and the flags -O2 -m64 -mcmodel=large". You can unpack this at the iraf root to replace your existing binaries, or else just extract the libraries you need. Tasks compiled and a simple hello.f imfort task runs but I can't make any guarantee about the daophot code. Hope this helps.

Hi - Thanks for posting these libraries. This in fact solved the problem, although I had to recompile the CFITSIO libraries (for some unknown reason). So, DAOPHOT/ALLSTAR compiled just fine, and once I test it I will post a more complete set of instructions for how I got this working. I think it would be useful for those trying to get DAOPHOT to work on larger images.
