Hello everybody,
my BSP still uses an old version of linux / libC, that does not provide all modern features. Compiling utils-linux with PTXDIST-2023.09.0 was painless. Upgrading to PTXDIST-2023.11.0 caused several compilation errors. Both PTXDIST release uses the same version of utils-linux (2.39.2) the only difference being the build system. PTXDIST-2023.09.0 uses autotools, while PTXDIST-2023.11.0 uses meson. Here a list of the problems: My linux do not provide <linux/blkzoned.h>. This causes an error while compiling blkzone. My linux do not provide <linux/pr.h>. This causes an error compiling blkpr. My linux do not provide <linux/kcmp.h>. This causes an error compiling lsfd. My linux do not provide the symbol SIOCGSKNS in linux/sockios.h. This causes an error while compiling test_mkfds. In the autotool version, all these programs were disabled. This seems to be not possible with meson. My libC provides the symbol openpty in the libutils module. The PTXDIST-2023.09.0 makefile util-linux.make explicitly enables libutils, the PTXDIST-2023.11.0 explicitly disables them. I was able to find a solution to all the problems. Attached are my patches. In meson.build I disabled build of blkzone if linux/blkzoned.h does not exists, lsfd if linux/pr.h is missing, etc. In the makefile util-linux.make I just changed libutils form disabled to enabled. Maybe one can consider to use a parameter instead. I'm not sure if this is the best way to do, since it is my first experience with meson. It would be nice if somebody can check them, and maybe include them in the future versions of ptxdist. Ruggero
