我正在尝试在Centos系统中运行HPL 2.1。
这是我的make文件：

# You can skip this section if and only if you are not planning to use
# a BLAS library featuring a Fortran 77 interface. Otherwise, it is
# necessary to fill out the F2CDEFS variable with the appropriate
# options. **One and only one** option should be chosen in **each** of
# the 3 following categories:
#
# 1) name space (How C calls a Fortran 77 routine)
#
# -DAdd_ : all lower case and a suffixed underscore (Suns,
# Intel, ...), [default]
# -DNoChange : all lower case (IBM RS6000),
# -DUpCase : all upper case (Cray),
# -DAdd__ : the FORTRAN compiler in use is f2c.
#
# 2) C and Fortran 77 integer mapping
#
# -DF77_INTEGER=int : Fortran 77 INTEGER is a C int, [default]
# -DF77_INTEGER=long : Fortran 77 INTEGER is a C long,
# -DF77_INTEGER=short : Fortran 77 INTEGER is a C short.
#
# 3) Fortran 77 string handling
#
# -DStringSunStyle : The string address is passed at the string loca-
# tion on the stack, and the string length is then
# passed as an F77_INTEGER after all explicit
# stack arguments, [default]
# -DStringStructPtr : The address of a structure is passed by a
# Fortran 77 string, and the structure is of the
# form: struct {char *cp; F77_INTEGER len;},
# -DStringStructVal : A structure is passed by value for each Fortran
# 77 string, and the structure is of the form:
# struct {char *cp; F77_INTEGER len;},
# -DStringCrayStyle : Special option for Cray machines, which uses
# Cray fcd (fortran character descriptor) for
# interoperation.

我认为它与libs路径有关，但我无法继续......
有没有人遇到过这种或问题？
答案 0 :(得分：0)
看起来没有找到地图集和pthreads
undefined reference to 'ATL_dsyreflect'
undefined reference to 'pthread_setspecific'
你需要正确地链接到这个或者在地图集的情况下，它可能被错误地构建。
我相信pthreads需要一个-lpthread标志，我上面没有看到这个标志，我也看不到任何地图集
答案 1 :(得分：0)
至于Pthreads错误：在构建最终可执行文件时，每个MPI库都需要链接一定数量的外部依赖项。这就是使用gcc或g77链接MPI可执行文件不是一个好主意的原因。而是应该使用mpicc或mpif90或另一个MPI编译器包装器。无论如何，如果指定-pthread，则链接Pthreads。
至于ATLAS错误：命令行中列出静态库的顺序很重要（它不适用于动态库）。在你的情况下，你有：
... /usr/lib64/atlas/libatlas.a /usr/lib64/atlas/libcblas.a ...
通过这样的安排，链接器将无法解析libcblas.a内的代码到libatlas.a内的代码的任何引用。这是由链接器完成的单通道符号解析所致。 libcblas.a应该在libatlas.a之前，而不是之后。
