| Upgrading Libtool |
| ----------------- |
| |
| If you are in the mood to upgrade libtool, you must do the following: |
| |
| 1. configure/build/install libtool with --prefix=<PFX> |
| 2. Copy <PFX>/share/aclocal/libtool.m4 to llvm/autoconf/m4/libtool.m4 |
| 3. Copy <PFX>/share/libtool/ltmain.sh to llvm/autoconf/ltmain.sh |
| 4. Adjust the llvm/autoconf/m4/libtool.m4 file to ensure that the variable |
| default_ofile is set to "mklib" instead of "libtool" |
| 5. Possibly adjust llvm/autoconf/m4/libtool.m4 to get rid of autoconf |
| warnings related to obsolete autconf features (e.g. AC_TRY_LINK) |
