| 4 | Subject: [PATCH] Fix libtool detection |
| 5 | |
| 6 | Upstream-Status: pending |
| 7 | |
| 8 | Use LT_INIT instead of the deprecated AC_PROG_LIBTOOL to detect libtool, so it |
| 9 | can work with our libtoolize and libtool. |
| 10 | |
| 11 | Simplify the detection of ltdl. It will find the ltdl from the sysroot; the |
| 12 | switch --with-system-libltdl is no longer needed. The code is copied from |
| 13 | pulseaudio configure.ac, together with the comment paragraph. |
| 14 | |
| 15 | Also patch autogen.sh so it uses autoreconf, which handles libtoolize better. |
