Hi, Short version: unless I made a mistake, I think that the shared libraries pjmedia, pjmedia-audiodev and pjmedia-videodev should be merged to a single shared library. Long version: I'm the maintainer of the pjproject (pjsip) packages for Debian[1]. Currently the package includes a single source package that builds multiple binary packages, one per shared library, as per the Debian Policy Manual[2]. One problem with the package is that the libraries include too many run-time dependencies: I originally packaged it for Asterisk (which uses pjsip and a few other componenets, but not pjmedia and such). However the way the current build system works, all libraries are linked with any library that is needed for any other library. This is not an issue with static linking. But it is an issue with shared libraries built in a generic configuration. Specifically, when I start getting bug reports about Asterisk linking with -SDL[3]. Originally we tried to fix this by an increasingly intrusive set of changes to the build system to avoid passing unneccesary build flags. Current master has them[4]. But this didn't seem to be a useful direction. So I realised that what I needed was not linking libraries that are not really needed. So what I really needed was linking with --as-needed[5]. This resulted in quite a few linking errors. Most were fixed by changes to ldflags ordering[6]. Sadly I failed to make pjmedia and the rest of the pjmedia* libraries link. It seems pjpedia needs symbols from pjmedia-audiodev and pjmedia-videodev and vice-versa (See traces below). So I guess this means the three libraries cannot be separated and need to be merged to a single shared library.

Hi Tzafrir, If the problem is that the libraries include too many run-time dependencies, won't it be better to specifically disable these unwanted dependencies instead? For example, by specifying --disable-video (or disable-ffmpeg, disable-ssl, disable-v4l2, etc) and --disable-opencore.

While playing with the build system to implement this (and naturally, breaking stuff as I go along), I noticed that I got a broken .depends file.

I now have a rough copy of the changes. http://anonscm.debian.org/cgit/pkg-voip/pjproject.git/log/?h=master-mergelibs This is a branch with a messed history that includes those changes, but the tree (and specifically debian/patches and debian/rules) should be OK. I added an extra patch to remove -lpjmedia-audiodev and -lpjmedia-videodev and disable building them. I wanted to avoid a big intrusive renaming patch, and thus I "copied" them into pjmedia/src/pjmedia/ using symlinks (adding a prefix to the .c files to avoid collision of errno.c). This symlinking is not done in a patch. Rather, it is done in the build rules, in debian/rules.

Hi Tzafrir, I am afraid that we can't proceed the proposal of merging pjmedia modules at least for now. It seems to introduce quite major changes for allowing '--as-needed' linker option while there are already options in configure scripts to strip the unnecessary dependency libs (which is originally introduced by the configure script itself).

Hi Tzafrir, We decide to remove circular deps of pjmedia* libraries in ticket #1907 ( https://trac.pjsip.org/repos/ticket/1907). Although this does not directly solve the original problem of too many runtime dependencies, hopefully it can give more flexibility towards what you can do. Please let us know if you have any feedbacks or suggestions. Thanks.
