#1058: Cygwin libraries & GNU libtool
 Reporter: mike_at_[hidden] | Type: Bugs
   Status: new | Milestone: To Be Determined
Component: Building Boost | Version: release 1.34.0
 Severity: Regression | Keywords: Cygwin libtool shared dll
 I'm using Cygwin on Windows XP with Boost 1.34.0 + the patches from these
 two tickets applied:


 The build and install stages seem to work correctly now, but now when I
 try to link in Boost libraries with my own shared library, GNU libtool
 (1.5.23a) is giving me errors about not being able to find the "real
 filenames" and refuses to build DLLs (it only builds shared libraries
 which is a problem for me since I'm building plug-ins):

 /bin/sh ../libtool --tag=CXX --mode=link g++ -DLIBPION -ggdb -Wall -no-
 undefined -release 0.1.7 -mthreads -L/opt/build/boost-1.34.0/lib -o
 libpion.la -rpath
 /usr/local/libpion-0.1.7/lib PionPlugin.lo PionEngine.lo TCPServer.lo
 HTTPTypes.lo HTTPResponse.lo HTTPRequestParser.lo HTTPServer.lo
 -lboost_thread-mt -lboost_system-mt -lboost_filesystem-mt -lws2_32

 *** Warning: linker path does not have real file for library
 *** I have the capability to make that library automatically link in when
 *** you link to this library. But I can only do this if you have a
 *** shared version of the library, which you do not appear to have
 *** because I did check the linker path looking for a file starting
 *** with libboost_thread-mt but no candidates were found. (...for file
 magic test)

 The import library names are currently using the format "boost_*.dll.a"
 while libtool expects libraries to have the standard "lib" prefix. Adding
 the "lib" prefix seems to fix this problem. Note that previous Boost
 releases (namely 1.33.1) used the format that is compatible with libtool
 -- 1.34.0 seems to have broken compatibility.
