Have a look here for all the changes: https://gitlab.com/sane-project/backends/-/merge_requests/853/diffs#d20bd4c65270e6b76cbb764eaebb98c4823f0bda In particular, there is a library addition to the Makefile.am in the backend directory on line 1622 to add the $(MATH_LIB) variable to the front of that line. > I have then tried to build from the source and copying > the debian folder (from the apt-get source) into it and changing the > changelog file. > > dwz: > debian/libsane1/usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1.2.1: > DWARF compression not beneficial - old size 10513109 new size 10551199 > dh_strip -a > debian/rules override_dh_makeshlibs-arch > make[1]: Entering directory '/home/m/sane-backends-1.3.0-2-marco' > dpkg-parsechangelog: warning: debian/changelog(l5): badly formatted > trailer line > LINE: -- Marco M <m...@dorfdsl.de> Sat, 28 Sep 2024 12:21:33 +0200 > dh_makeshlibs --exclude=/sane/ -- -v1.3.0-2 -Pdebian/libsane1 -plibsane1 > dh_makeshlibs: warning: debian/changelog(l5): badly formatted trailer > line > LINE: -- Marco M <m...@dorfdsl.de> Sat, 28 Sep 2024 12:21:33 +0200 > dpkg-gensymbols: error: some symbols or patterns disappeared in the > symbols file: see diff output below > dpkg-gensymbols: warning: debian/libsane1/DEBIAN/symbols doesn't match > completely debian/libsane1.symbols > --- debian/libsane1.symbols (libsane1_1.3.0-2_amd64) > +++ dpkg-gensymbolsSfWUpp 2024-09-28 12:44:32.953663717 +0200 > @@ -1,7 +1,7 @@ > libsane.so.1 libsane1 #MINVER# > * Build-Depends-Package: libsane-dev > (arch=!hurd-i386 !kfreebsd-any)cmsg@Base 1.0.29 > - fail_test@Base 1.0.29 > +#MISSING: 1.3.0-2# fail_test@Base 1.0.29 > md5_buffer@Base 1.0.27 > md5_finish_ctx@Base 1.0.27 > md5_init_ctx@Base 1.0.27 > dh_makeshlibs: error: failing due to earlier errors > > There was an error that I accidentally introduced. That has been fixed now but I did get this from the PPA build as well. Honestly, I would take the source package as-is from Debian, update that Makefile.am and the rts8891*.* source and it should build the package. I'm going to be pretty busy this weekend, but I will try to find time to have a go myself as well to make sure that the process works. Cheers, Ralph
