Build a shared library for DS-5

Mark

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

Armadillo: C++ linear algebra library

I get it to work with general Linux GCC and it runs on my Red Hat computer

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

When I try to use the DS5 tool chain I get

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

So it works with g++ but not with arm-linux-gnueabihf-g++.  How should I build the library?  I just built the default way.  cmake .   make  and make install.  Any ideas what I should do?  Can I even run this library on the Cyclone?
