[Libguestfs] [Hivex] OS X and iconv

Hi all, The linking problem I found yesterday appears to be because of the built-in iconv in OS X. So, this is a request for patch or pointers: What needs to happen with configure.ac or the iconv.m4 macro file to link an iconv library _besides_ the one in /usr/local/lib? That's the tl;dr, full explanation follows. That library lacks the x86_64 architecture: $ file /usr/local/lib/libiconv.dylib libiconv.dylib: Mach-O universal binary with 2 architectures libiconv.dylib (for architecture i386): Mach-O dynamically linked shared library i386 libiconv.dylib (for architecture ppc): Mach-O dynamically linked shared library ppc Make complains, though it could stand to complain with more violence to the build: [snip] Making all in tools make[3]: Nothing to be done for `all'.

The way to get compilation to work is to remove the iconv library files from /usr/local/lib [2, 3]. I tried moving them to a temporary folder, and when I did that and rebuilt, Hivexml ran without a hitch. So, what would work in configure.ac to get Hivex to remove /usr/local/lib from the library paths for OS X, but just for iconv? Or is the correct answer to file a complaint with Apple and commence thumb-twiddling? --Alex [1] http://stackoverflow.com/a/18170376/1207160 [2] http://stackoverflow.com/a/4929905/1207160 [3] https://trac.macports.org/ticket/28302
