How to use GNU GSL library for LPCxpresso 4367

Hi.

I need to use the GSL library in my program. 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.

Can someone please help me on this?

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

Do I have to cross compile the library again for Arm compiler? If yes, can you please provide me the procedure as well?

Thanks

To anwer the easy question:

>>Do I have to cross compile the library again for Arm compiler?

Because your LPC device won't be able to run x86 code (or variants of it), you have to crosscomple il.

Thanks Erich. But can you please also tell me the procedure since this is my first time to cross compile something.
