Hi, I've got a library, libLHAPDF.so, which is accessed by a SWIG Python wrapper, implemented as a libtool library module, _lhapdf.so. In order to work, _lhapdf.so needs to open the main LHAPDF library to get the function definitions, so my Makefile.am for the SWIG wrapper contains the line
_lhapdf_la_LIBADD = $(top_builddir)/lib/libLHAPDF.la which on my system puts a nice NEEDED section into the .so: [EMAIL PROTECTED]:~/proj/hep/lhapdf$ objdump -p pyext/.libs/_lhapdf.so [...] Dynamic Section: NEEDED libLHAPDF.so.0 NEEDED libstdc++.so.6 [...] And all is well. However, on another developer's machine, the NEEDED reference to libLHAPDF.so.0 is present in the build directory, but missing in the installed library. The result is that the Python import of the "lhapdf" module fails due to undefined symbols. After a bit of investigation I noticed that libtool is actually creating a secondary "T" version of the library: [EMAIL PROTECTED]:~/proj/lhapdf/pyext$ ls -l .libs/_* -rw-r--r-- 1 whalley nisusers 1705640 2008-10-10 17:06 .libs/_lhapdf.a lrwxrwxrwx 1 whalley nisusers 13 2008-10-10 17:06 .libs/ _lhapdf.la -> ../_lhapdf.la -rw-r--r-- 1 whalley nisusers 976 2008-10-10 17:06 .libs/ _lhapdf.lai -rw-r--r-- 1 whalley nisusers 1689040 2008-10-10 17:06 .libs/ _lhapdf_la-lhapdf_wrap.o lrwxrwxrwx 1 whalley nisusers 16 2008-10-10 17:06 .libs/ _lhapdf.so -> _lhapdf.so.0.0.0 lrwxrwxrwx 1 whalley nisusers 16 2008-10-10 17:06 .libs/ _lhapdf.so.0 -> _lhapdf.so.0.0.0 -rwxr-xr-x 1 whalley nisusers 1090000 2008-10-10 17:06 .libs/ _lhapdf.so.0.0.0 -rwxr-xr-x 1 whalley nisusers 1090000 2008-10-10 17:43 .libs/ _lhapdf.so.0.0.0T (note the timestamp on .libs/_lhapdf.so.0.0.0T ... I tried deleting it and it was automatically rebuilt) This version is missing the library chaining NEEDED entry for libLHAPDF and is the one that's installed, since this appears in the build log: /usr/bin/install -c .libs/_lhapdf.so.0.0.0T /scratch/local/lib/ python2.5/site-packages/_lhapdf.so.0.0.0 Can anyone help? I can't find anything useful on the Web or in the libtool documentation about these "T" suffixes, and it's currently blocking release of the library!
