這是我的makefileMakefile文件編譯的問題
FC=gfortran
CC=gcc
CPC=g++
FFLAGS = -O3
LINK=g++
BLASF=dgemmf.o dgemmkernel2.o mult.o
BLASFSRC=dgemmf.f
TIMER=mytimer.o
TGEMM=tgemm
ALL= $(TGEMM)
LIBS = -lblas
all: $(ALL)
mult.o:
$(CPC) -O3 -fopenmp -c mult.cpp
$(TGEMM): tgemm.o mult.o $(TIMER) $(BLASF)
$(FC) $(FFLAGS) -o $(TGEMM) tgemm.o $(TIMER) $(BLASF) $(LIBS)
dgemmkernel2.o: dgemmkernel2.cpp
$(CPC) -O3 -c -fopenmp dgemmkernel2.cpp
tgemm.o: tgemm.f $(INCLUDE)
$(FC) $(FFLAGS) -c tgemm.f
clean:
rm -rf *.o $(ALL)
這是我得到的錯誤:

我從我的研究瞭解,這些都有可能連接的問題,但我不能爲生命我找出問題所在。有沒有人可以對此問題有所瞭解?
試過了,它給了我現在的錯誤。我會看看我能找到什麼。/usr/bin/ld:tgemm.o:未定義的符號引用'_gfortran_set_options @@ GFORTRAN_1.0' /usr/bin/ld:注意:'_gfortran_set_options @@ GFORTRAN_1.0'在DSO/usr/lib64 /請嘗試將其添加到鏈接器命令行中 /usr/lib64/libgfortran.so.3:無法讀取符號:無效操作 – Tesomas 2011-12-16 00:31:57
