[Linphone-users] building linphone 3.12.0 on Debian 12

[Fourhundred Thecat]

Hello,

I need to build older linphone version for Debian 12.

I have downloaded sources for linphone 3.12.0 from Debian 10, and on my
Debian 12 build machine, I have installed all required dependencies.

Now when I start the build:

  dpkg-buildpackage --build=binary --no-sign

it terminates right at the beginning, with following error:

    dh_auto_configure: error: cd obj-x86_64-linux-gnu && cmake
-DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=None
-DCMAKE_INSTALL_SYSCONFDIR=/etc -DCMAKE_INSTALL_LOCALSTATEDIR=/var
-DCMAKE_EXPORT_NO_PACKAGE_REGISTRY=ON
-DCMAKE_FIND_USE_PACKAGE_REGISTRY=OFF
-DCMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY=ON
-DFETCHCONTENT_FULLY_DISCONNECTED=ON -DCMAKE_INSTALL_RUNSTATEDIR=/run
"-GUnix Makefiles" -DCMAKE_VERBOSE_MAKEFILE=ON
-DCMAKE_INSTALL_LIBDIR=lib/x86_64-linux-gnu -DCMAKE_SKIP_RPATH=ON
-DENABLE_ROOTCA_DOWNLOAD=NO -DENABLE_GTK_UI=YES .. returned exit code 1
    make[1]: *** [debian/rules:20: override_dh_auto_configure] Error 2
    make[1]: Leaving directory '/mnt/src/deb/LINPHONE/linphone-3.12.0'
    make: *** [debian/rules:15: binary] Error 2
    dpkg-buildpackage: error: fakeroot debian/rules binary subprocess
returned exit status 2

here is debian/rules[1] file and here[2] is the full output of the build
process:

  [1]: https://bpa.st/L3CTE
  [2]: https://bpa.st/3TI72

any idea why it is failing?
