Thanks Paul! well it is looking for b.out.... --- configure:1840: $? = 0 configure:1854: checking for Fortran compiler default output file name configure:1857: ifort -c -O2 -convert big_endian -free -assume byterecl conftest.f >&5 configure:1860: $? = 0 configure:1908: result: b.out configure:1913: checking whether the Fortran compiler works configure:1919: ./b.out ./configure: line 1920: ./b.out: No such file or directory ------ nbut I don't see any file names conftest.f (locate either) when I run with FCFLAGS=-g ; it is looking for a.out and finds it (didn't find any file with that name either) and keeps on going... this happens in configure there: ----- # b.out is created by i960 compilers. for ac_file in a_out.exe a.exe conftest.exe a.out conftest a.* conftest.* b.out do test -f "$ac_file" || continue case $ac_file in *.$ac_ext | *.xcoff | *.tds | *.d | *.pdb | *.xSYM | *.bb | *.bbg | *.o | *.obj ) ;; conftest.$ac_ext ) # This is the source file. ;; [ab].out ) # We found the default executable, but exeext='' is most # certainly right. break;; *.* ) ac_cv_exeext=`expr "$ac_file" : '[^.]*\(\..*\)'` # FIXME: I believe we export ac_cv_exeext for Libtool, # but it would be cool to find out if it's true. Does anybody # maintain Libtool? --akim. export ac_cv_exeext break;; * ) break;; esac done --- it does say b.out is created by i960 compilers but my compiler hasn't changed ; just the flags....? I did print out the path and it is in my current directory... I don't have any a.out or b.out.... I'll keep on digging but I am at a lost here....
