Hi, I've spoken about this in the past but it looks like I should mention it again. I do extensive cross compiling of the entire Linux software stack using OpenEmbedded and Poky (I maintain the latter). We have cross compiling working with libtool with a variety of workarounds. This mainly consists of the following simple patch to libtool itself:
http://git.pokylinux.org/cgit.cgi/poky/tree/meta/packages/libtool/libtool/cross_compile.patch and then manipulation of the .la files with sed if we ever want to move the sysroot directory, or use the .la files on the target device. There are a couple of other patches we use. One is to allow multiple libtool scripts to live in the same place by adding a cross prefix to the tool name: http://git.pokylinux.org/cgit.cgi/poky/tree/meta/packages/libtool/libtool/prefix.patch This patch also allows us to tell when the "wrong" (unpatched) libtool is being used. The final patch we're currently applying is probably a bug in libtool: http://git.pokylinux.org/cgit.cgi/poky/tree/meta/packages/libtool/libtool/trailingslash.patch where a directory comparison was failing as one variable ended in a slash and the other did not. We're fixing this by stripping any slash off both options (the patch is pending an update to do this). I haven't isolated a proper test case to be able to submit this one as a proper bug yet though. Longer term I'm still hoping we'll see sysroot support in libtool and I may even find some time to start the ball rolling on patches eventually but I'm not going to get to that soon, much as I wish it were otherwise.
