Hello, https://lists.rtems.org/pipermail/devel/2020-June/060145.html As agreed on the above mail I have started to create patches based on the new build system. But I encountered a few issues related to the inclusion of header files. I am using one of my patches as an example to illustrate the issues.
The BUILD System was pulled from Sebastians build branch ( https://git.rtems.org/sebh/rtems.git/log/?h=build ) PROJECT STRUCTURE: The FreeBSD files imported to RTEMS are placed under cpukit/libfreebsd/freebsd They follow the same file structure as in FreeBSD ( COMMIT [1] ). I have also implemented a few structures to make porting from FreeBSD easier and reduce the amount of redundant code. These files are *currently* placed under cpukit/libfreebsd/rtems ( COMMIT [2] ) The spec file for libfreebsd is objfreebsd.yml [3] with the following contents in the include path. We currently don't install anything. install: [] includes: - cpukit/libfreebsd - cpukit/libfreebsd/freebsd - cpukit/libfreebsd/freebsd/sys - cpukit/libfreebsd/rtems The files discussed here have the following structure ti_pinmux.c, ti_pinmux.h, ti_cpuid.h are present under libfreebsd/freebsd/sys/arm/ti bus.c, device.h, bus.h are present under libfreebsd/rtems For full list of files please refer to [4] ISSUES: 1) Can't include headers present under libfreebsd in BSPs directory. For eg: I want to include ti_cpuid.h [5] in BSP directory but can't do so even though the path has been added to the spec file. [3] In beagle/bspstart.c: #include <arm/ti/ti_cpuid.h> throws an error even though the path has been added in the spec file. 2) Is it possible to have two same files one in RTEMS and other in RTEMS-libBSD without collision? At least with different install paths? For eg: The openfirm.h in RTEMS under something like libfreebsd/dev/ofw/openfirm.h And the open in libBSD as it is done currently. So this way we can include the RTEMS variant with #include <libfreebsd/dev/ofw/openfirm.h> Thanks, Niteesh [1] https://github.com/gs-niteesh/rtems/commit/4e7b3cd7c3f8e6ea71f7a1e988562b0b7a5a540e [2] https://github.com/gs-niteesh/rtems/commit/dbad2319a153513d02e7c0ab290ac72c04a5a715 [3] https://github.com/gs-niteesh/rtems/commit/5eac1348c1b2fe2fdc406a3e573b66885f6eb93e [4] https://github.com/gs-niteesh/rtems/tree/pinmux_rtems6/cpukit/libfreebsd [5] https://github.com/gs-niteesh/rtems/blob/a4859fe053482b0b6b09c01b28fd06027356f3be/bsps/arm/beagle/start/bsp-soc-detect.h#L36
