Source: dpkg Severity: wishlist Tags: upstream Just to see what trickery I could get away with, I tried cross building dpkg with MinGW. It fails due to lchown being missing, but it seems like this is one of the only functions that dpkg dies on not finding: AC_CHECK_FUNCS([memcpy lchown], [], [AC_MSG_ERROR([missing required function])])
I notice there's precedent for incorporating something into libcompat, which actually looks a lot like Gnulib. From the outside it looks like reinventing the wheel and I'm curious about that, but either way Gnulib has a module that may help portability on other platforms. It appears it just dies with ENOSYS on MinGW, at least for now, but I'll take it :) https://www.gnu.org/software/gnulib/manual/html_node/lchown.html If you wish to avoid embedded code copies, the Gnulib Debian package has it. Otherwise a similar libcompat function that dies might still be fun to try, and if it bears serious consequences perhaps a flag could be required to enable. -- Package-specific info: System tainted due to merged-usr-via-symlinks. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing'), (2, 'unstable'), (1, 'testing-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.9.0-4-amd64 (SMP w/2 CPU threads) Kernel taint flags: TAINT_USER, TAINT_WARN, TAINT_FIRMWARE_WORKAROUND Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled -- no debconf information
