gfortran：找不到架构x86_64的符号

标签： gcc makefile fortran gfortran

我正在尝试一周以来编译用F90和C编写的代码。我一直收到一个未定义的符号错误。我会尽量提供尽可能多的信息，但包中包含数百个文件，所以提供所有细节有点困难。这是Makefile

#      Double check that the "LOWO" flags have been set.  In case they have not, clone the #
# standard options.  LOWO stands for LOWer Optimisation, and these flags are used for a    #
# subroutines that are taking several hours to compile with ifort-13 (ed_state_vars.f90    #
# and a few others).                                                                       #

# interface ----------------------------------------------------
# This should be 1 unless you are running with -gen-interfaces.

# If USE_MPIWTIME=1, then it will use MPI libraries to compute
# the wall time (the only double-precision intrinsic).  In case
# you don't have it, leave USE_MPIWTIME=0, in which case it will
# use a simpler, single-precision function.

答案 0 :(得分：1)

这是一个链接器错误。您似乎没有链接到包含_calchydrosubsurface_的.o文件或库中。在不知道您使用的源代码或库的情况下，很难帮助您，但告诉您要查找的内容：

搜索包含 calchydrosubsurface 的源代码或库;找到后，请确保正确导出符号（nm <object file>），并确保链接到make文件中的符号。
