我已编译代码但它无法正常工作。我的makefile：
FC= ifort
LD = ifort -align all
FCFLAGS = -O0 -g -ipo -traceback -warn noalign
LDFLAGS = $(FCFLAGS)
# Executables
nray: main.o findnode.o plots.o segmnt.o empty.o aldone.o erase.o pcolor.o box.o plot.o axtick.o axis.o line.o pltsrcbox.o find.o dot.o grad.o intersect.o straight.o backproj.o ddtime.o kernel.o resolution.o plotnd.o bndinterpret.o time.o $< $(INCS)
$(FC) $(LDFLAGS) $(FCFLAGS) -o nray main.o findnode.o plots.o segmnt.o empty.o aldone.o erase.o pcolor.o box.o plot.o axtick.o axis.o line.o pltsrcbox.o find.o dot.o grad.o intersect.o straight.o backproj.o ddtime.o kernel.o resolution.o plotnd.o bndinterpret.o time.o $< $(INCS)
main.o:main.f ray.par ray.com
$(FC) $(FCFLAGS) -c main.f
所以，如果我想知道为什么backproj.o不起作用，我该怎么办？

答案 0 :(得分：2)
您正在阅读文件的末尾：
/home/milenko/fast/ray/num.cell
这可能是因为num.cell不够长或者您的阅读程序没有在正确的位置停止。违规读取在main.f的第226行或至少在那里被称为。
如果没有看到某些代码，真的不能说更多。
问题似乎不太可能是backproj.f（听起来不像应该/将会读取文件的那种例程），但这只是基于你的例程名称的猜测。
答案 1 :(得分：1)
您正在尝试读取文件num.cell的fortran运行时库中收到并结束文件错误。第一步应该是检查该文件的内容是否有效。
