clapack linking errors

[aortizb]

Hello all,

I am trying to compute the inverse of a matrix with lapack. I am
getting some link errors. The code is:

---------------------------------------------------------------------------------------

#include <iostream>
#include <string>
#include <vector>
using namespace std;

extern "C" int dpotrf_(char *uplo, int *n, double *a, int *lda, int
*info);
extern "C" int dpotri_(char *uplo, int *n, double *a, int *lda, int
*info);

int main()
{
int n = 2;
int info;
char uplo = 'u';

vector< vector<double> > a(2,vector<double>(2));
a[0][0] = 1;
a[0][1] = 1;
a[1][0] = 1;
a[1][1] = 1.000000001;

dpotrf_(&uplo,&n,&a[0][0],&n,&info);
if (info != 0)
cout << "Error in dpotrf(): Flag is " << info << endl;

dpotri_(&uplo,&n,&a[0][0],&n,&info);
if (info != 0)
cout << "Error in dpotri(): Flag is " << info << endl;

vector< vector<double> > ainv(2,vector<double>(2));
for (int i = 0; i < n; i++)
for (int j = 0; j < i-1; j++)
ainv[i][j] = a[j][i];

for (int i = 0; i < 2; i++)
{
for (int j = 0; j < 2; j++)
cout << ainv[i][j] << " ";
cout << endl;
}

return 0;
}

-------------------------------------------------------------

I am using the precompiled libraries of lapack and f2c that comes with
TAUCS (liblapack.lib and vcf2c.lib).

Can i get some help/guidance with the following errors?.

Thanks.
Alejandro.

Please use a pastebin service, like pastebin.com, for posting long
code fragments and error messages. A good pastebin service will also
have syntax highlighting and automatic indentation of source code.
This can be a big help for us, especially if our e-mail clients mess
up the indentation of your original source code.

It looks like the precompiled binaries are expecting symbol names that
aren't there. It's hard to say more unless we can see your Makefile.

The linking errors are coming from libcmpmtd. It looks like that you are
compiling with -MD while the libraries from TAUCS are compiled with -MT.
Try to compile the code with -MT. If you need -MD, then you need to
recompile the libraries with -MD.

Yet I get lots of errors. I decide to use gcc instead. I have a folder "gcc"
where the following files are located: clapack_example.cpp, liblapack.lib

I have tried this in "gcc" folder:

g++ -c clapack_example.cpp
g++ -o example clapack_example.o -L ../gcc -llapack

The last line gives me the following output: collect2: ld returned 1 exit
status.

What might be the problem here?

I figured out that I am using the libraries for MVS *.lib, which were not

They actually should work but you need to rename them. With -llapack
gcc searches for the file liblapack.a.

However with gcc you can use precompiled ATLAS that available here with
the instruction on how to do it with an example of DGEMM

http://matrixprogramming.com/MatrixMultiply/

Look at

Using Specialized Libraries: BLAS and ATLAS

[Alejandro A. Ortiz Bernardin]

Ok. Thanks. I'll try it. In order to start I just want to be sure what
libraries I have to use. I'll use your precompiled libraries.
You have: libatlas.a, libblas.a, libcblas.a, libf77blas.a and liblapack.a

Should I use all of them? Some of them? or just liblapack?

It looks like xerbla is trying to call Fortran intrinsics that aren't
linked in. You could try including the Fortran runtime library when
you link. What that should be depends on the Fortran compiler with
which the relevant libraries were built.

You really only need one LAPACK library and one BLAS library. I
shouldn't say more as I don't build on this particular system and I
don't want to confuse you with my ill-informedness ;-)

First about the libraries at my site. They are from ATLAS, that is,
liblapack.a needs ATLAS libs, not BLAS. Note that liblapack.a is not
complete but routines you need are there.

f77blas was compiled with g77 and it requires g2c. Then the order of the
libraries was not correct, gcc searches the library only once. By me the
next command is working

$ g++ inverse.cpp -L. -llapack -lf77blas -lcblas -latlas -lg2c

but then there is segmentation fault when I run the binary (a.exe in
this case). Some output is though is available.

With libraries from TAUCS I was also able to compile and link the code
with MS VC

$ cl -EHsc -MT inverse.cpp lapack_win32.lib blas_win32.lib vcf2c.lib

These are original LAPACK and the reference BLAS and below is ATLAS

$ cl -EHsc -MT inverse.cpp liblapack.lib libf77blas.lib libcblas.lib
libatlas.lib vcf2c.lib

As I have already mentioned you need -MT, as the libraries are compiled
with -MT. If you use -MD, then I see a lot of linking errors. With VC
however, there is a crash without any output. Please repeat with either
gcc or VC and then try to fix the code. A good idea is to insert more
outputs.

For me too. Thanks.

What strange ... I don't get segmentation fault .. but I don't get the
correct inverse, though.

I don't have these libraries. I just have the ones from ATLAS, so I didn't
try it.

>> and below is ATLAS

>> $ cl -EHsc -MT inverse.cpp liblapack.lib libf77blas.lib libcblas.lib

There is something strange here. If I do it from the command line with cl as
you have shown above, it is working fine for me too. Again, I don't get
segmentation fault but not the correct inverse.

Now, if I do it from the MVS GUI, I get lots of errors. I have specified the
same flags as you did from command line above, i.e., -EHsc and -MT. I guess
that other flags might be activated by default in the GUI which is causing
the errors?

I posted the errors here: http://pastebin.com/m7ff68d01

Probably I have used the wrong code. If inverse is not correct, it is
necessary to check the calls. There is an example from NAG

http://www.nag.com/numeric/fl/manual20/pdf/F07/f07fjf.pdf

It could be possible to find other examples as well.

I think that they have been also in TAUCS. Definitely I have not
compiled them by myself.

It is the same. You will receive them from the command line if you use
-MD instead of -MT. I guess that you need to click something in GUI, not
just give the option -MT as such. But I do not know GUI, sorry. You may
want to ask about this at somewhere at microsoft.public.vc.*

Possibly you used my old code (I had posted a correction, so you might have
picked the wrong one). Finally, I found out what the problem was. C version
of lapack expects the matrix in a vector ordered by columns. Here is the
code working perfectly:

http://pastebin.com/m7a8c8873 ,

which can be built with:

g++ -c inverse.cpp
g++ -o inverse inverse.o L./ -llapack -lf77blas -lcblas -latlas -lg2c

It would be great if you can post it in matrixprogramming.com

Thanks for your always valuable help!
Alejandro.

I tried to solve this but I couldn't. There are lots of thing in the command
line that are put by default. Here is the complete command line

I'll ask in Microsoft.

Finally, I just specify \MTd in the GUI and the errors disappeared. However,
I don't understand why in the command line works fine with just -MT.
