I suppose you apply these modifications to a libtool that you are compiling. However, libtool is typically already embedded in each upstream tarball. Do you run autoreconf on all packages, so that a newer libtool script gets generated (autoreconf-ing each package takes a lot of time) ? Do you somehow replace the provided libtool by a fixed one ? Moreover, some packages use libtool 1.5.x and some newer packages use libtool 2.2.x. How do you handle this version difference ? > There are other workarounds we have to apply after installing > packages, particularly modifying the .la files to be uninstalled to > get the sysroot to work properly. « to be uninstalled » ? In Buildroot, we already modify the libdir='' in all the .la files so that they refer to the sysroot instead of /usr/lib. If possible, could you point me to the location in OpenEmbedded where libtool is handled ? I already had a look at your patches, but don't understand how you re-generate the libtool script inside the different upstream packages. Thanks!
