The following patch should then be enough to break the Build-Depends cycle: From 150724d38cb335fdc8fceae95e1905d694c278eb Mon Sep 17 00:00:00 2001 From: Sebastian Ramacher <[email protected]> Date: Wed, 7 Jan 2015 21:48:22 +0100 Subject: [PATCH] Use build profiles to break Build-Depends cycle --- debian/control | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/debian/control b/debian/control index a81227d..1696564 100644 --- a/debian/control +++ b/debian/control @@ -17,7 +17,8 @@ Build-Depends-Indep: doxygen Build-Depends: debhelper (>= 9), - frei0r-plugins-dev, + dpkg-dev (>= 1.17.14~), + frei0r-plugins-dev <!stage1>, libasound2-dev [linux-any], libbz2-dev, libcdio-cdda-dev, @@ -31,7 +32,7 @@ Build-Depends: libmp3lame-dev, libopencore-amrnb-dev, libopencore-amrwb-dev, - libopencv-dev, + libopencv-dev <!stage1>, libopenjpeg-dev, libopus-dev (>= 1.0.1), libpulse-dev, @@ -49,7 +50,7 @@ Build-Depends: libvorbis-dev, libvpx-dev, libx11-dev, - libx264-dev, + libx264-dev <!stage1>, libx265-dev, libxext-dev, libxfixes-dev, -- 2.1.4 I have not commited it yet in case we want to upload the experimental branch before jessie has been release.
