dyld[34280]: symbol not found in flat namespace (_cblas_caxpy)

Hello,

I am trying to run the GNU Scientific Libraries on a M1 MacBook, using the Eclipse IDE. The source code is minimal:

#include <stdio.h>

#include <stdlib.h>

#include <gsl/gsl_sf_bessel.h>

int main(void) {

puts("Simple GSL Test"); 
double x = 5.0;
double y = gsl_sf_bessel_J0 (x);
printf ("J0(%g) = %.18e\n", x, y);
return EXIT_SUCCESS;

}

Linking runs without warnings:

17:02:47 **** Incremental Build of configuration Debug for project TestGSL **** make all Building file: ../src/TestGSL.c Invoking: GCC C Compiler gcc -I/opt/homebrew/Cellar/gsl/2.7.1/include -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/TestGSL.d" -MT"src/TestGSL.o" -o "src/TestGSL.o" "../src/TestGSL.c" Finished building: ../src/TestGSL.c

17:02:47 Build Finished. 0 errors, 0 warnings. (took 516ms)

Running gives the following error:

dyld[34729]: symbol not found in flat namespace (_cblas_caxpy)

I was unable to find the proper solution.

Does someone know how to fix it ?

Many thanks,

Luca
