Armadillo C++ -- LAPACK and BLAS

(1/2) > >>

Hello all,

I am pretty new to using Code::blocks. Hence, I apologize beforehand in case my question sounds stupid.
I am trying to install Armadillo. One of the installation steps asks to configure my compiler to link with the LAPACK and BLAS libraries. I already have the following files:

1) blas_win32_MT.dll
2) blas_win32_MT.lib
3) lapack_win32_MT.dll
4) lapack_win32_MT.dll

How can I link those libraries?

I am grateful for your response.

Best,
Houl

Within your project options -> build options -> tab "linker" -> add the library you need to use in the right order. IT also depends on whether you are using the static or dynamic runtime version.

Consult the C::B manual (http://www.codeblocks.org/docs/main_codeblocks_en.html) to see screenshots where to setup this information.

Jenna:
You most likely have to add the path to the linker installation directory to the libraries search paths in the build options, at least if they are not in the systems search path.

Thank you for all...It is working now.

Best,

Hello ,

I tried many hours and still I couldn't figure out how to do this.
I found
1) blas_win64_MT.dll
2) blas_win64_MT.lib
3) lapack_win64_MT.dll
4) lapack_win64_MT.lib
files in C:\armadillo-5.100.2\armadillo-5.100.2\examples\lib_win64    directory.
Then as MortenMacFly suggested I did " project options -> build options -> tab "linker" -> add the library " . I added only .lib versions since  when I add .dll compiler doesn't build the project and tells unrecognized format.

After I compile the program it says "undefined reference to `dgemv_' . It is obvious that comiler cannot find lapack and blas libraires.
Can you guys please help me to fix this.
Thank You.
