Building on RISC-V (riscv64gc-linux)

by Kevin Ingwersen

Hello there! I am having a bit of a "moment" here, trying to build ucLibC on my VisionFive2. I have configured most of the things I would like the library to feature, but when I try to actually build it, it can not find my headers properly. I have tried /usr, /usr/include and also used find to locate the folders that it was looking for, but to no avail. It is either linux/errno.h, asm/errno.h or asm/unistd.h that can not be found. The kernel is self-built (since the upstream currently lacks two patches required for full SoC support) off the 6.6.0 branch and headers are installed to their standard location, including /usr/src/linux-headers-$(uname -r). What is the expected structure to be found under .config's KERNEL_HEADERS? Thank you and kind regards, Ingwie

To obtain correct `st_atim`, `st_mtim` and `st_ctim` fields we need to use statx() syscall and then convert the data from the kernel to the regular stat structure.

[PATCH 1/2] Refactor `ts32_struct` and `TO_ITS64_P`.

by Dmitry Chestnykh

- Renamed `ts32_struct` to `__ts32_struct` like `__ts64_struct` and moved its definition to the header. - Removed extra space from TO_ITS64_P() macro.
