Question

I am doing some matrix multiplication in C and I am trying to compile my progam however it fails to compile for the reason:

No such file or directory cblas.h

This is the command I am using to compile:

gcc -o BLAS BLAS.c

Can anybody please help me? I am compiling this program on a server. I’m not sure if this makes a difference.

Answer 1

You need to add a -I directory option where directory is the place where the cblas.h file is located on your system.

This gives:

gcc -o BLAS -I directory_of_cblas_header BLAS.c
