Thank you Faidon for the info.
The issue is because the functions (which throws error) are
defined in <termios.h> and seems like somehow it is not
getting added in the source. Currently, this library is added
based on the following condition:
#if defined(__linux__) && !defined(NO_TCGETS2)
#include <asm/termbits.h>
#else
#include <termios.h>
#endif
Removing the lib from condition and adding it explicitly gives
the error like "error: redefinition of 'struct termios'"
because the similar structure also been defined in
<termbits.h>. I am trying to check if termbits is required
by any of the archs, if not we can remove it, else we can rely on
some code tweaks to fix this redifinition error

See https://buildd.debian.org/status/package.php?p=bootterm&suite=sid.Thank you for your report. Confirmed, although to clarify, it's just ppc64el that's affected, and it's not a regression (it never worked). 32-bit powerpc is the only other Linux port that is affected, but it's an unofficial port, as are the Hurd ports.Able to reproduce the issue while building the package on pp64el and checked the build logs from pp64el (https://buildd.debian.org/status/fetch.php?pkg=bootterm&arch=ppc64el&ver=0.5-1&stamp=1744757613&raw=0). The error seems to be because of some library missiing. Checking more on this.I had brought this up with upstream about a year ago. This is about non-standard custom baud rates and platform differences, on either the kernel side, glibc side, or both -- that part is unclear to me. In the time since, glibc 2.41 was released, which includes a news entry on <termios.h> gaining support for arbitrary baud rates, so perhaps the right cross-platform fix here is to change the code to rely on that, instead of using <termbits.h> directly. It needs a bit more research, and ideally to run this by upstream as well, as I don't have any way to test this particular functionality. Feel free to take this on, otherwise I may find some time in the next few months to look at it. Regards, Faidon
