OS X 10.6 build (gcc + ifort): ncl, ctrans, ictrans

Just thought I'd share some results of building ncl_ncarg_5.2.1 on OS X (10.6) with gcc 4.2.1 (build 5646) and Intel ifort 11 (089). Ncl/ncarg were built 32-bit (not sure if hdf4 builds 64-bit easily yet), and then 64-bit non-ncl (to get 64-bit ncarg libs).

1.) ncl had to be linked by hand with ifort. Even with "CtoFLibraries -lifcore -lsvml -limf -lirc", gcc couldn't find "_flush_" or "_abort_". So I used "ifort -m32 -nofor-main" instead.

2.) ctrans and ictrans both had the same kind of error:

gcc -ansi -m32 -O -o ctrans main.o ../../../.././ncarview/src/lib/libctrans/libctrans.o -L../../../.././ncarview/src/lib/libcgm -lcgm -L../../../.././ncarview/src/lib/libncarg_ras -lncarg_ras -L../../../.././common/src/libncarg_c -lncarg_c -L/opt/local/ncarg521/lib -L/usr/X11/lib -L/opt/local/netcdf4m32/lib -L/opt/local/hdf5m32/lib -L/opt/local/lib -lXpm -lX11 -lXext -lmfhdf -ldf -ljpeg -lz -lm
ld: duplicate symbol start in ../../../.././ncarview/src/lib/libctrans/libctrans.o and /usr/lib/crt1.10.6.o
collect2: ld returned 1 exit status

So I looked at how libctrans.o and libictrans.o were being built, and noticed a warning:

gcc -m32 -bind_at_load -r -o libctrans.o bitops.o buffer.o clip.o ctrans.o default.o fill.o fontlist.o format.o gcap.o gcread.o in.o rast.o readfont.o rgbtohls.o text.o translate.o env.o soft_fill.o cell.o commondev.o gcapdev.o gcaprast.o rastdev.o hatch.o pal.o ctrans_api.o cgmmisc.o misc.o X11_class0.o X11_class1.o X11_class3.o X11_class4.o X11_class6.o X11_class7.o Xcrm.o xresources.o clear_text.o devices.o
ld: warning: unexpected dylib (/usr/lib/libSystem.dylib) on link line
ld: warning: unexpected dylib (/usr/lib/system/libmathCommon.A.dylib) on link line

Since this looked like a library, really, I tried "ar vru" instead:

ar vru libctrans.o bitops.o buffer.o clip.o ctrans.o default.o fill.o fontlist.o format.o gcap.o gcread.o in.o rast.o readfont.o rgbtohls.o text.o translate.o env.o soft_fill.o cell.o commondev.o gcapdev.o gcaprast.o rastdev.o hatch.o pal.o ctrans_api.o cgmmisc.o misc.o X11_class0.o X11_class1.o X11_class3.o X11_class4.o X11_class6.o X11_class7.o Xcrm.o xresources.o clear_text.o devices.o

and that seemed to make the linking for ictrans happy. (Same procedure for libictrans.o/ictrans)

I haven't tested ctrans and ictrans yet, but ictrans at least outputs a help message. (ncl does seem to be working.) I don't recall this issue from 5.0.0, which is the previous version I compiled on OS X.

Site.local and Darwin_Intel files are copied below (32-bit).
