Compile Error

[flylcl]

I got this error message after run compile in eclipse.
Hope someone help me.
Thanks.

Looks like you have a C library that was compiled with -mcmodel=medlow and an application compiled with -mcmodel=medany. If you recompile the C library to match the application, these link errors will disappear.

[jim-wilson]

If you built your own compiler, you can use --with-cmodel=medany to get one that defaults to medany.

aswaterman, Thanks your reply,
I found that my C library was compiled with medlow. I'm trying to compile C library with medany.
Btw, I got more error message after change the riscv compile option to medlow same as C libaray.
Could you explain the reason?

[jim-wilson]

You didn't report the new errors with medlow, so we can't say anything about them.

It works fine after build the toolchain with medany option as you mentioned.
Thanks a lot.
