These symbols are referenced in the loaded module ... https://git.rtems.org/rtems/tree/testsuites/libtests/dl06/dl06-o2.c This test gets rtems-ld with the RAP format to collect the atan1 and tan code into the loaded module. They should not be present in the base image. The libm library is used because it is _not_ part of the standard libraries linked and is available everywhere. > Fix this issue by adding -lm. Is the error linking the base kernel image or the RAP loadable module? If it is the loadable module and this is how you add the libraries to be searched to the rtems-ld command then the fix is needed and there is no problem. If the error was in the base kernel image then I suggest something else is wrong because those symbols should not be present in the base image. If the build system can support options for just rtems-ld then adding it there would be good. More of a concern is no error. I wonder if the code is being inlined when there is FPU support. Maybe the test needs to create a library linking to it to be more robust?
