I'm trying to understand the problems I am having on some systems regarding libarchive, lzma, and xz. I have an 8-Stable system updated yesterday. As far as I can tell, libarchive does include the lzma stuff from libzma. At least I see the references. But several ports seem to still pull in xz-5.0.1 and link to it. This has a wonderful potential to cause library symbol conflicts. I get: /usr/lib/libarchive.so: undefined reference to `lzma_stream_encoder@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_alone_decoder@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_memusage@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_stream_decoder@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_code@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_end@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_lzma_preset@XZ_5.0' /usr/lib/libarchive.so: undefined reference to `lzma_alone_encoder@XZ_5.0' ldd shows libarchive linked against liblzma.so.5 and an objdump of the dynamic symbols from liblzma.so.5 shows the "undefined symbols" defined with the XZ_5.0 version, so I am mystified. It looks o me like it is there. Is confusion with xz-5.0.1 causing this? Should get rid of it? Even so, I don't understand why the loader is claiming that these symbols are undefined when they seem to be defined as far as I can tell. 0000000000007c60 g DF .text 0000000000000084 XZ_5.0 lzma_stream_encoder Any clues to what i happening would be greatly appreciated! -- R.
