本文介绍了链接导入MAT文件的Fortran代码时出错的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我必须在fortran程序中导入MAT文件。我遵循示例文件,但我遇到了一些问题同时链接。

最小代码:

  #include fintrf.h

程序main

USE ssa
USE dmotifs
USE参数

隐式无

! MAT-FILE声明!

INTEGER matOpen,matGetDir
INTEGER matGetVariableInfo
INTEGER mp,dir,adir(100),pa
INTEGER mxGetM,mxGetN,matClose
INTEGER ndir,我,clstat
字符* 32个名字(100)

!=========================== !

if(all(fnames(:)%fn .NE。argfun))then
write(*,*)No such motif:,argfun
write(* ,*)输入格式 - >主< motifname>
stop
else

fin = fchton(argfun)
y0 = nM2m * analys(p,argfun)

! ==>打开MAT文件< ==!

mp = matOpen('./ PRMS_lxr_29Apr15.mat','r')

if(mp .eq。0)then
write(6,* )无法打开MAT文件
stop
end if

dir = matgetdir(mp,ndir)

if(dir .eq 。0)then
write(6,*)无法读取MAT文件目录。
stop
endif

call mxCopyPtrToPtrArray(dir,adir,ndir)

do 20 i = 1,ndir
call mxCopyPtrToCharacter(adir (i),姓名(i),32)
20继续

写(6,*)'文件目录:'

30 i = 1,ndir
write(6,*)names(i)
30 continue

write(6,*)'从第一个数组获取标题信息'$ b $ (6,*)'已检索',名称(1)
write(6,*)'With size',mxGetM(pa), '-by-',mxGetN(pa)
调用mxDestroyArray(pa)

clstat = matClose(mp)

如果
结束END PROGRAM main

我使用gfortran 4.8.3编译+使用默认命令链接:

  gfortran main.f90 dmotifs.o param.o ssa.o -o main 

当我不包含以下代码时,该代码可以很好地编译(无链接): #includefinitrf.h,否则编译器会说:

 警告:main.f90:1:非法预处理器指令

我尝试将 finitrf.h 重命名为 finitrf。 f90 但它没有任何区别。然而,在链接期间,我收到了这些错误:

  main.f90 :(。text + 0x3ea):未定义引用'matopen_' 
main.f90 :( .text + 0x487):对`matgetdir_'的未定义引用
main.f90 :( .text + 0x52b):对`mxcopyptrtoptrarray_'的未定义引用
main.f90: (.text + 0x583):对'mxcopyptrtocharacter_'的未定义引用
main.f90 :( .text + 0x71b):未定义对`matgetvariableinfo_'的引用
main.f90 :( .text + 0x804):undefined引用'mxgetm_'
main.f90 :(。text + 0x855):对`mxgetn_'的未定义引用
main.f90 :( .text + 0x89c):对`mxdestroyarray_'的未定义引用
main.f90 :( .text + 0x8b0):对`matclose_'的未定义引用
collect2:错误:ld返回1退出状态

我是否需要makefile或在编译命令中添加其他参数?



编辑:



我添加了 -cpp 选项并消除了 Ill例如,预处理程序指令



现在,当我用matlab外部组件(其中finitf.h)编译路径时,错误。

  gfortran main.f90 dmotifs.o param.o ssa.o -I / usr / local / matlab2008a / extern /包括-L / usr / local / matlab2008a / extern / lib -cpp -o main 

如果我提供库路径为 / usr / local / matlab2008a / bin / glnxa64 ,其中包含其他matlab库,包括 libmat.so ,I仍然会有同样的错误。正如Alexander Vogt指出的那样,编译器需要 -cpp 预处理器可以选择识别头文件,而不是将其视为非法。

链接需要 finitrf.h ,它通常位于< matlabroot> / extern / include ,并且基本库存在于< matlabroot> / bin /< arch> / 中。

但是,只是指定这不起作用,并且确切的matlab库的规范似乎是必不可少的;这些是 libmat.so libmx.so

这些库依次依赖于其他库,因此需要另一个标志来设置 rpath



最后使用以下命令:

  gfortran main.f90 dmotifs.o param.o ssa.o -I / usr / local / matlab2008a / extern / include -L / usr / local / matlab2008a / bin / glnxa64 -cpp -o main -lmat -lmx -Wl,-rpath / usr / local / matlab2008a / bin / glnxa64 / 

或一般

  gfortran program.f90 -I< matlabroot> / extern / include -L< matlabroot> / bin /< arch> -cpp -lmat -lmx -Wl,-rpath< matlabroot> / bin /< arch> -o program.out 

另见这个帖子与 C 中的问题大致相同。

I have to import a MAT-file in a fortran program. I followed the example file but I am facing some problems while linking. The compilation happens fine.

Minimal code:

#include "fintrf.h"

PROGRAM main 

USE ssa
USE dmotifs
USE param

IMPLICIT NONE

! MAT-FILE Declarations !

INTEGER matOpen, matGetDir 
INTEGER matGetVariableInfo
INTEGER mp, dir, adir(100), pa
INTEGER mxGetM, mxGetN, matClose
INTEGER ndir, i, clstat
CHARACTER*32 names(100) 

!===========================!

if(all(fnames(:)%fn .NE. argfun)) then
    write(*,*) "No such motif: ",argfun
    write(*,*) "Input format-> main <motifname>"
    stop
else

    fin=fchton(argfun)  
    y0=nM2m*analys(p,argfun)

    ! ==> OPEN MAT-file <== !

    mp=matOpen('./PRMS_lxr_29Apr15.mat','r')

    if (mp .eq. 0) then
         write(6,*) "Can't open MAT-file"
         stop
    end if

    dir = matgetdir(mp, ndir)

      if (dir .eq. 0) then
         write(6,*) "Can't read MAT-file-directory."
         stop
    endif

    call mxCopyPtrToPtrArray(dir, adir, ndir)

    do 20 i=1,ndir
         call mxCopyPtrToCharacter(adir(i), names(i), 32)
 20 continue

    write(6,*) 'Directory of Mat-file:'

    do 30 i=1,ndir
        write(6,*) names(i)
 30 continue

    write(6,*) 'Getting Header info from first array.'
    pa = matGetVariableInfo(mp, names(1))
    write(6,*) 'Retrieved ', names(1)
    write(6,*) '  With size ', mxGetM(pa), '-by-', mxGetN(pa)
    call mxDestroyArray(pa)

    clstat=matClose(mp)

end if
END PROGRAM main

I am using gfortran 4.8.3 for compiling+linking using the default command:

gfortran main.f90 dmotifs.o param.o ssa.o -o main

This code compiles fine (without linking) when I do not include: #include "finitrf.h", otherwise the compiler says

Warning: main.f90:1: Illegal preprocessor directive

I tried renaming finitrf.h to finitrf.f90 but it did not make any difference. Nonetheless during linking I am getting these errors:

main.f90:(.text+0x3ea): undefined reference to `matopen_'
main.f90:(.text+0x487): undefined reference to `matgetdir_'
main.f90:(.text+0x52b): undefined reference to `mxcopyptrtoptrarray_'
main.f90:(.text+0x583): undefined reference to `mxcopyptrtocharacter_'
main.f90:(.text+0x71b): undefined reference to `matgetvariableinfo_'
main.f90:(.text+0x804): undefined reference to `mxgetm_'
main.f90:(.text+0x855): undefined reference to `mxgetn_'
main.f90:(.text+0x89c): undefined reference to `mxdestroyarray_'
main.f90:(.text+0x8b0): undefined reference to `matclose_'
collect2: error: ld returned 1 exit status

Do I need a makefile or add additional arguments in the compile command?

EDIT:

I added the -cpp option and that eliminates the problem of Illegal preprocessor directive

Now when I am compiling with paths to matlab external components (where finitf.h) is, I am still getting the same error.

gfortran main.f90 dmotifs.o param.o ssa.o -I/usr/local/matlab2008a/extern/include -L/usr/local/matlab2008a/extern/lib -cpp -o main

If I provide library path to /usr/local/matlab2008a/bin/glnxa64 that contains other matlab libraries including libmat.so, I still get the same errors.

解决方案

As pointed out by Alexander Vogt, the compiler requires -cpp option for the pre-processor to recognize the header file and not to treat it as illegal.

Linking requires finitrf.h which is usually located in the <matlabroot>/extern/include and the essential libraries are present in <matlabroot>/bin/<arch>/.

But just specifying this does not work and specification of the exact matlab library seems essential; these are libmat.so and libmx.so.

These libraries are in turn dependent on other libraries so another flag is required to set the rpath.

Finally it works with following command:

gfortran main.f90 dmotifs.o param.o ssa.o -I/usr/local/matlab2008a/extern/include -L/usr/local/matlab2008a/bin/glnxa64 -cpp -o main -lmat -lmx -Wl,-rpath /usr/local/matlab2008a/bin/glnxa64/

or in general

gfortran program.f90 -I<matlabroot>/extern/include -L<matlabroot>/bin/<arch> -cpp -lmat -lmx -Wl, -rpath <matlabroot>/bin/<arch> -o program.out
