How to cross compile GSL library for arm-none-eabi-gcc?

I need to use the GSL library in my program on LPCXpresso 4367(ARM CORTEX M4). I tried to follow the library linking procedure for LPC xpresso but the MCU linker is giving me these errors:

MCUXpressoIDE_10.3.0_2200\workspace\test1\Debug/../src/test1.c:53: undefined reference to 'gsl_linalg_LU_decomp'

MCUXpressoIDE_10.3.0_2200\workspace\test1\Debug/../src/test1.c:56: undefined reference to 'gsl_matrix_alloc'

MCUXpressoIDE_10.3.0_2200\workspace\test1\Debug/../src/test1.c:57: undefined reference to 'gsl_linalg_LU_invert'

and so on for other functions as well.

I have the libgsl.a and libgslcblas.a precompiled libraries for windows which works perfectly on codeblocks on windows with GCC compiler.

I read that I need to crosscompile library for the arm-none-eabi-gcc toolchain. But can someone please provide me the procedure as well?

Solution

  • the libgsl.a and libgslcblas.a precompiled libraries for windows

    Those won't do for ARM.

    In order to work on another platform, these libs need to be compiled from source code with the proper compiler (and settings - Cortex-M4F requires Thumb2 instruction set).
