[MITgcm-support] problem of pgf77

[WangYang]

dear all,
when doing ''make" , the error comes as follow:


cat cd_code_init_fixed.F | ../../../tools/set64bitConst.sh |  cpp  -traditional -P -DWORDLENGTH=4 -DHAVE_SYSTEM -DHAVE_FDATE -DHAVE_ETIME -DHAVE_CLOC -DHAVE_SETRLSTK -DHAVE_SIGREG -DHAVE_STAT  -I.  > cd_code_init_fixed.f
pgf77 -byteswapio -r8 -Mnodclchk -Mextend -Ktrap=fp  -tp k8-64 -pc=64 -O2 -scalarsse -Mvect=sse -c cd_code_init_fixed.f
pgf77-Error-Unknown switch: -scalarsse
make: *** [cd_code_init_fixed.o] Error 1


I am very confused because it runs well before. 
Does anyone know the reason?
Thanks a lot for your help!
