Issues running DAAL example on Windows with gcc

[Antonio_R_]

Hello,

I'm trying to run the DAAL examples compiling with Mingw on Windows 10 with cmd and i'm running into a very strange issue. I've set the env variables, can compile the .cpp but when I get into the linking part the problem in the sshot below shows up:

C:\daal-daal_2017_update3>g++ -v -I%DAALINCLUDE% cholesky_dense_batch.cpp -L%DAALLIB% -ldaal_core -ldaal_sequential -lpthread -lm -o cholesky_dense_batch.exe
Using built-in specs.

I don't uderstand why it doesn't find  those references because they are in the files (I can compile the examples in Visual Studio with Intel C and VC). It appears to me that the #include path is wrong but I don't thats the case because the whole library would be wrong if so.

Any help is appreciated. Thanks for your time and patience.

Hello Antonio,

Here are the reasons why Intel DAAL examples cannot be built with MinGW:

• MinGW compiler is not supported by Intel DAAL 2017. Please find the list of the compilers supported for Windows in Intel DAAL System Requirements.
• Intel DAAL DLLs are written in C++ and are built with Visual Studio runtime. When you try to build some example with MinGW, you see "undefined reference" errors because Visual Studio and MinGW mangle C++ names differently. That is why MinGW linker cannot find the expected symbols in the library. Please see the following MinGW Wiki page for more information: "Interoperability of Libraries Created by Different Compiler Brands"

Best regards,

Victoriya
