[vlc-devel] vlc3 : cannot link with libaccess_srt_plugin

[Justin Kim]

Hello,

Let me try to check this problem more.
I tested the following sequences;

   $ cd <vlc>/contrib
   $ mkdir native
   $ cd native
   $ ../bootstrap --enable-srt
   $ make fetch-all
   $ export PKG_CONFIG_LIBDIR=<somewhere>/pkgconfig
   $ make

Then, although this 'make' reported some linking errors, I fixed them 
locally. After that, I could get 'contrib' stuffs.

   $ cd <vlc>
   $ ./bootstrap
   $ ./configure --enable-srt
   $ make

Then, I could get vlc executable. The different thing is that I did this 
build on archlinux and ubuntu.

Can you tell me what is different from you did?

BR,
Justin
