Taucs configuration notes

 

Since I learned that taucs can be used to calculate the sparse matrix two days ago, I have studied it for a long time. It has been compiled many times and the Lib of precompiled has also been compiled, but it is not successful. I asked my brother in the afternoon and finally completed the test process.

The procedure is as follows:

Using taucs from Gui

 

Now it is also possible to compile and run the code from GUI

 

Specifying the information above through the dialog boxes.

 

1) Note that taucs was compiled with-MT. Specify it also in C ++ -->

 

Code Generation --> use run-time library. (select multi-

 

Threaded debug DLL (/MDD ))

 

2) Specify the path to the taucs headers in additional include

 

Directories. (add the directory of the header file)

 

3) Specify the library to link with in link --> input: Object/Library

 

Modules.

 

4) Specify the path to the libraries in additional path library. (add

 

Add the. lib directory, and then add the above. Lib file to linker --> input --

 

> Additional dependencies: only a path is added to the. lib directory.

 

Need to add one by one)

 

The. Lib file is

 

Libatlas. Lib

Libcblas. Lib

Libf77blas. Lib

Liblapack. Lib

Libmetis-vc80-mt.lib

Libmetis-vc80-mt-gd.lib

}

The precompiled header can run smoothly on vs2008. C ++ -->

 

Code Generation --> use run-time library. (For Runtime Library, select multi-threaded debug (/MTD ))

 

The specific reason is estimated that the Lib is different, so the selected CRT (C Runtime Library is different)
