     I am writing to see if you can give me some guidance on the following error I am having. I am trying to migrate a module from EPICS 3.15.8 to EPCIS 7. The module compiles correctly, except that when I invoke the make command for RTEMS the lib directory is not created automatically. If I change the macro in the Makefile to compile for the other platforms, in this case, linux_x86_64 the lib directory is created when the make command is invoked. Basically, by declaring the macro LIBRARY_IOC_RTEMS += <module_name_lib>, the lib directory is not created when invoking make, whereas if you change the macro to

LIBRARY_IOC += <module_name_lib> the lib directory is created.

    To provide more information, with the previous version (EPICS 3.15.8) it behaves as expected but with EPICS 7, this is not the case. Maybe I need to take something into account with the new version of EPICS to have the same effect as with the previous version.

Which version of EPICS 7.0.x are you using, and which version of RTEMS?

Could you also copy & paste the exact error messages you are getting from the build, and the lines leading up to them to show context.

There should be no major differences in the build system between 3.15.8 and any 7.0.x release. We added experimental support for RTEMS-5 in the 7.0.6 release which changed some aspects of RTEMS builds, but it builds fine for us. Note that the <top>/lib/RTEMS-<bsp> directory should only be created when it actually has a library to install, and possibly only at the point of install.
