rtems 5.3 released libbsd hash mismatch
Greetings. New developer here. I used RSB 5.3 to target RTEMS to RaspberryPi with an AMD64 Debian bullseye. sha512sum rtems-libbsd-5.3.tar.xz listed in VERSION is hash mismatch. Correct is: c84482cb33e178bdc1e4bbb0390a54d4f9c12db1f1614876dd4ae5218d4b26c2aa61d368bf3fafefcbc49e57008de9f636b11c596310d33320a0152002b012de ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

utf32 support
I want to add utf32 support. Where do I start? — John ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
Re: utf32 support
A 32 bit character type is supported by FreeBSD. Unicode 2012 says utf32 must be a 32 bit signed integer. Unicode only defines the Codepoint character attribute. RTEMS now uses libBSD and newlib. Need kernel to support the Codepoint range of values. Applications can then use additional user-defined character attributes. — John P.S.: UTF32 exists for Unicode in 2012 after consolidation from ISO 10646-2012. The two standards merged. On Mar 19, 2024, at 6:20 AM, Frank Kühndel wrote: Hello John, just a side node: Strictly speaking UTF32 does not exist [1]. The correct name is UCS-4 (i.e store each character in four bytes).

Re: 6.1rc3 CentOS 7 Build Sweep Report
UTF-8 start byte cannot be 0xff. Off-by-1 bug is possible. Maybe a hidden control character is throwing off the count but being stripped away prior to the attempt to convert to UTF-8.

Ada
Hello. I need Ada for RTEMS on Raspberry Pi. I will settle for whichever versions work together. After moving to gitlab, is Ada continuously built and tested for RTEMS? Today, my non-gitlab RSB 5.3 build failed on Debian with error in GNAT 7.5.0 for the aspects.adb file. (That Python UTF-8 non-incremental parsing failure also occurred, but Chris Johns recently identified and fixed that problem.) I will move to gitlab only if necessary. -- John ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

You need to use a native compiler that is the same version as what you are building cross.

Re: Ada
> gcc -v You might try forcing arm mode without supporting thumb modes. If I remember right, official Arm document obsoleted Thumb1, which would explain the “sorry” message. gcc.pdf (.html) helps. Also, there is a separate mailing list for the GCC linker problems. Experts might better assist there. Also, GNAT repo maintainers or AdaCore could help. GNAT Ada works on RPi. Configuration info from there might help you. My Raspberry Pi Debian (Bullseye) on AMD64 has GCC 10.2.1 from 20210110. RPi repos generally don’t update to recent or development versions of GCC. Older RPi repos are removed to force users to upgrade. Official Debian repos do not support the ArmV6 found in original Raspberry Pi or Zero (arm1176JZF-S). But Raspbian Debian does for bare metal gcc with noneabi packages (I use Synaptic packager to locate the installed files of interest). For example, my obsoleted Raspbian repo version on RPi 3B+, /usr/share/doc/gcc-6-doc/gcc.pdf reveals -mcpu=arm1176jzf-s is sufficient. and /usr/share/doc/gcc-arm-none-eabi/readme.txt.gz reveals Cortex-A* (Hard FP) command line options: [-mthumb] -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 or for multilib: armv7-ar /thumb /fpu - - John On Jun 24, 2024, at 9:08 AM, Sebastian Huber wrote: Hello John, I have some issues on arm and Ada with current versions of GCC, see also: https://gcc.gnu.org/pipermail/gcc/2024-June/244197.html ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
