I am trying to run the Armadillo Linear Algebra package on my Cyclone V. 

 

I get it to work with general Linux GCC 

 

Invoking: GCC C++ Compiler g++ -I/usr/include -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/Armadillo_Test.d" -MT"src/Armadillo_Test.d" -o "src/Armadillo_Test.o" "../src/Armadillo_Test.cpp" Finished building: ../src/Armadillo_Test.cpp Building target: Armadillo_Test Invoking: GCC C++ Linker g++ -L/usr/lib64 -o "Armadillo_Test" ./src/Armadillo_Test.o -lm -larmadillo -llapack -lblas -larpack Finished building target: Armadillo_Test 

 

Then I try to build for DS5 and the cyclone board 

 

Invoking: GCC C++ Compiler arm-linux-gnueabihf-g++ -I/usr/include -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/Armadillo_Test.d" -MT"src/Armadillo_Test.d" -o "src/Armadillo_Test.o" "../src/Armadillo_Test.cpp" Finished building: ../src/Armadillo_Test.cpp Building target: Armadillo_Test Invoking: GCC C++ Linker arm-linux-gnueabihf-g++ -L/usr/lib64 -o "Armadillo_Test" ./src/Armadillo_Test.o -lm -larmadillo -llapack -lblas -larpack /usr/lib64/libarmadillo.so: file not recognized: File format not recognized collect2: error: ld returned 1 exit status 

 

Any ideas what I could try?

Does anyone know if the cross compiler, which comes with the Yocto, should build up the correct library? I followed this but step two fails.

Will I need to get another? My error is: 

gcc: error trying to exec 'cc1': execvp: No such File or directory

That error indicates that GCC can't find one of the files it needs to do compiling. It isn't related to the library you are trying to build. You will find that you can't compile anything.  

 

I've seen that error before when environment variables GCC needs weren't set correctly. Unfortunately, I don't know how to fix this for Yocto. Is there a script you need to run to set it up?
