Thanks. Looking at the commit: @@ -0,0 +1,4 @@ +This code was imported from https://git.kernel.org/cgit/utils/dtc/dtc.git, +commit 64c46b098b969502a74c8b0fd97e6f5e4aa07e21. To save space, the DTC code +has been removed. The libfdt directory is unmodified, and the directory +structure unchanged, to simplify future merging. I was expecting this to be essentially the result of: mkdir mini-os.git/libfdt cp dtc.git/libfdt/* mini-os.git/libfdt git add -r mini-os.git/libfdt But it seems you did something else a bit more complex? IMHO this has actually made future merging more difficult, not easier, since the person doing the merge now needs to consider what out of dtc.git/* they need to copy over as well as just updating the libfdt directory but repeating the cp and looking at git status. Also, there seems to be two copies of libfdt_env.h now, one in include and one in dtc/libfdt. Not sure if that is intentional or a problem? Lastly I'm afraid the build rune supplied in the commit message doesn't work for me, lots of -Werror=int-to-pointer-cast, see attached output from: $ make XEN_TARGET_ARCH=arm32 CROSS_COMPILE=arm-linux-gnueabihf- \ > CONFIG_TEST=y CONFIG_START_NETWORK=n CONFIG_BLKFRONT=n \ > CONFIG_NETFRONT=n CONFIG_FBFRONT=n CONFIG_KBDFRONT=n \ > CONFIG_CONSFRONT=n CONFIG_XC=n -k |& tee ~/mini-os.log $ arm-linux-gnueabihf-gcc --version arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.8-2014.04 - Linaro GCC 4.8-2014.04) 4.8.3 20140401 (prerelease) Copyright (C) 2013 Free Software Foundation, Inc.

Thanks. Looking at the commit: @@ -0,0 +1,4 @@ +This code was imported from https://git.kernel.org/cgit/utils/dtc/dtc.git, +commit 64c46b098b969502a74c8b0fd97e6f5e4aa07e21. To save space, the DTC code +has been removed. The libfdt directory is unmodified, and the directory +structure unchanged, to simplify future merging. I was expecting this to be essentially the result of: mkdir mini-os.git/libfdt cp dtc.git/libfdt/* mini-os.git/libfdt git add -r mini-os.git/libfdt But it seems you did something else a bit more complex? IMHO this has actually made future merging more difficult, not easier, since the person doing the merge now needs to consider what out of dtc.git/* they need to copy over as well as just updating the libfdt directory but repeating the cp and looking at git status. Also, there seems to be two copies of libfdt_env.h now, one in include and one in dtc/libfdt. Not sure if that is intentional or a problem? Lastly I'm afraid the build rune supplied in the commit message doesn't work for me, lots of -Werror=int-to-pointer-cast, see attached output from: $ make XEN_TARGET_ARCH=arm32 CROSS_COMPILE=arm-linux-gnueabihf- \ > CONFIG_TEST=y CONFIG_START_NETWORK=n CONFIG_BLKFRONT=n \ > CONFIG_NETFRONT=n CONFIG_FBFRONT=n CONFIG_KBDFRONT=n \ > CONFIG_CONSFRONT=n CONFIG_XC=n -k |& tee ~/mini-os.log $ arm-linux-gnueabihf-gcc --version arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.8-2014.04 - Linaro GCC 4.8-2014.04) 4.8.3 20140401 (prerelease) Copyright (C) 2013 Free Software Foundation, Inc.

Right now, we need a libc to sandwich between the two. As far as we know, Mini-OS only works well with Newlib and Rust only works well with glibc. There's also the option of musl. We'd be the happiest if we could make glibc work on Mini-OS, but we've seen points to this being very hard to accomplish. Instead, I've been trying to get a "Hello world!" Newlib/Mini-OS app to compile, based on a tutorial from 2006 on the subject[1]. Unfortunately, that resource seems hopelessly antiquated, so I figured I'd ask the experts :) I have several questions: 1. Have there been any efforts around getting glibc to run on Mini OS? Is there documentation on the subject? 2. Similarly, what's the status of Newlib on Mini-OS? How do you suggest we tackle that? 3. Which libc do you think we should go with? 4. How does the Mini-OS build system create a Xen-appropriate ELF file without the use of a cross-compiler? Most resources I've found recommend the use of a cross-compiler, but nothing of the sort seems to be happening here. Thanks in advance!

My answer to all three of these would be to suggest that you investigate rumpkernels (rumpkernels.org) which provides a BSD libc environment (which is more POSIX than newlib by far and should therefore be easier to get Rust working on). When targeting Xen rumpkernels uses mini-os for the lower levels and achieves similar aims in a much more pleasant and accessible way. Does rust run on native NetBSD? If so then that removes one big hurdle. Googling seems to suggest there have been some efforts in this direction but I'm not clear if they are "done". I would imagine that the rust maintainers would be more accepting of patches which make rust usable on NetBSD than they might be of newlib or some other even more niche libc, which means rust-on-rumpkernels would have less to maintain themselves. (my actual answer to 1a and 1b would be "No" and to 2 would be "moribund") > 4. How does the Mini-OS build system create a Xen-appropriate ELF > file without the use of a cross-compiler?
