Hello everyone.
I am trying to use a trial ALGLIB version with linking to pre-built MKL libraries.
My IDE is Code::Blocks, my compilers are MinGW g++ and TDM-64. I am building the application for Windows 64-bit environment.
When I am trying to build application without MKL libraries, it is fine. It is also fine when using Intel-specific optimizations ("AE_CPU=AE_INTEL"), SIMD-capable kernels ("-mavx2 -mfma") and when using muliprocessing capabilities ("AE_OS=AE_WINDOWS" and "alglib::setglobalthreading(alglib::parallel);"). But when I am trying to speed-up my application even more with linking to "alglib402_64mkl.lib" and using #define "AE_MKL", I get the following error:
Code:
alglib-cpp\addons-mkl\libalglib402_64mkl.lib: error adding symbols: File format not recognized
collect2.exe: error: ld returned 1 exit status
I also put the corresponding *.dll file to root folder of my application as it was demonstrated in manual.
I get the similar error message when linking to "libalglib402_64mkl.so".
When linking to 32-bit precompiled MKL library, I get the following error messages:
Code:
obj\Release\alglib-cpp\src\ap.o:ap.cpp: (.text+0x1d1a5): undefined reference to `_alglib2mkl_disable_fast_mm`
obj\Release\alglib-cpp\src\ap.o:ap.cpp: (.text+0x1d254): undefined reference to `_alglib2mkl_rmatrixtrsv`
...
(omitted, a lot of similar messages)
...
collect2.exe: error: ld returned 1 exit status
I suppose that I get these errors because MKL-interface libraries were built with Microsoft Visual Studio and my programm was built with MinGW g++/TDM-64.
Is that correct?
Do I need to install Microsoft Visual Studio to test ALGLIB with MKL-related features? Or maybe it is possible to build application for Windows with ALGLIB and MKL with MinGW g++ or TDM-64 compilers?
Thanks in advance.
