well...i left xfoil for along while..but then decided i needed it.
SO i got as far as make xfoil using gfortran.(added the flag -ff2c so it is compatible with f77 code)..this is when it says this:
../plotlib/libPltDP.a(ps_subs.o): In function `bitpat_':
ps_subs.f.text+0x78): undefined reference to `rshift_'
ps_subs.f.text+0xf9): undefined reference to `rshift_'
collect2: ld returned 1 exit status
make: *** [xfoil] Error 1
This is what the ps_sub.f file (the required portion) says:
c--- Shift the mask until the low order bit is 1 to start...
imask = mask
do n = 1, 16
ibitold = and(1,imask)
if(ibitold.NE.0) go to 5
nshft = n
imask = rshift(imask,1)
5 nout = 0
nbits = 0
anyone know how or what to do?i cant find anything on google.
