AS DESTDIR prepends the path to the existing prefix and exec-prefix, it creates unnecessarily deep directory hierarchies. For example. If I configure like this: ./configure --prefix=/home/dj/iroot --exec-prefix=/home/dj/iroot/x86 and then install as this: make DESTDIR=/home/dj/stage/rbtree-1.0.9 install I get a file hierarchy which looks like this: /home/dj/stage /home/dj/stage/rbtree-1.0.9 /home/dj/stage/rbtree-1.0.9/home /home/dj/stage/rbtree-1.0.9/home/dj /home/dj/stage/rbtree-1.0.9/home/dj/ /home/dj/stage/rbtree-1.0.9/home/dj/iroot /home/dj/stage/rbtree-1.0.9/home/dj/iroot/x86 /home/dj/stage/rbtree-1.0.9/home/dj/iroot/x86/lib /home/dj/stage/rbtree-1.0.9/home/dj/iroot/x86/lib/pkgconfig /home/dj/stage/rbtree-1.0.9/home/dj/iroot/include /home/dj/stage/rbtree-1.0.9/home/dj/iroot/include/rbtree This does not work well with the software I use (graft) to map things onto the public directory. I believe it might also cause problems with GNU stow. If instead I override prefix and exec_prefix: make DESTDIR=/home/dj/stage prefix=/rbtree-1.0.9 exec_prefix=/rbtree-1.0.9/x86 install The resultant file hierarchy is shallower: /home/dj/stage /home/dj/stage/rbtree-1.0.9 /home/dj/stage/rbtree-1.0.9/x86 /home/dj/stage/rbtree-1.0.9/x86/lib /home/dj/stage/rbtree-1.0.9/x86/lib/pkgconfig /home/dj/stage/rbtree-1.0.9/include /home/dj/stage/rbtree-1.0.9/include/rbtree and works well with the graft program. In the context of my original question vis-a-vis libtool, I've been using this approach for many years with a large number of distributions which use libtool and have never had libtool refuse to install a library into the staging area. _______________________________________________ https://lists.gnu.org/mailman/listinfo/libtool
