在make的时候出现错误：

pgf90 -I/home/wen/program/ioapi/ioapi/fixed_src -mcmodel=medium -O2 -pc 64 -Mdalign -Mnoframe -byteswapio -Mlfs -Bstatic_pgi -c spcmap.f
pgf90-Error-Unknown switch: -mcmodel=medium
make: *** [spcmap.o] Error 1


Makefile里边：
IOAPI_INC  = /home/wen/program/ioapi/ioapi/fixed_src
IOAPI_LIB  = /home/wen/program/ioapi/Linux2_x86_64pg
NETCDF_LIB = /home/wen/program/netcdf/lib

FC  = pgf90
OPT = -mcmodel=medium -O2 -pc 64 -Mdalign -Mnoframe -byteswapio -Mlfs -Bstatic_pgi
LIB = -L$(IOAPI_LIB) -lioapi -L$(NETCDF_LIB) -lnetcdf
INC = -I$(IOAPI_INC)
