I have a question about the libtool package and automake...
In my configure.in I have AC_PROG_LIBTOOL to set up the necessary bits n bobs. I also have the macro ACX_PTHREAD to determine which threading libraries are needed in order to link my app.
However on the final stage of make (and only since I added libtool to the project) it now fails with the errors below. Now I guess its not linking with the pthread library for some reason. -pthread is what the ACX_PTHREAD macro chooses both on solaris and linux, however if I copy and past the libtool link line at the bottom and change -pthread to -lpthread the final excecutable compiles with no problem. Any clues as to why this is, whats the difference and how to solve it?
Released libtool provides no special handling for -pthread so it is not passed to the compiler. Libtool 2.0 (in the throes of final bug-fixing and testing) will pass -pthread to the compiler.
As a work-around you can avoid using -pthread and pass the necessary pre-processor option (e.g. -D_REENTRANT) and library (e.g. -lpthread) via CPPFLAGS and LIBS.
For the package I support, I was not happy with ACX_PTHREAD so I use a modified version which provides the CPPFLAGS and LIBS info I need. The ACX_PTHREAD macro actually knows all of this internally, but requires some modifications to extract it.
