Re: [xml] Linker error Compiling off the HEAD

[jwert ilstechnology com]

Sorry for being a little incomplete...

Step1: Checkout Libxml2 from the gnome cvs server.
Step2: ./autogen.sh
Step3: make

And it fails there.

I also ran with ./autogen.sh --with-modules=no --with-zlib=no, and it
correctly didn't use libdl or libz, but still was missing pthreads.

Its a fully updated Redhat Enterprise3 WS build system.

Could it be a simple problem now when linking the xmllint you are not
explicitly linking with pthread?

(sorry for the double send to you Daniel, but forgot to CC the list).

Thanks,

  1/ did you ./autogen.sh ?
  2/ if yes what options
  3/ what platform ?
  4/ what compiler ?

libxml2 now uses weak symbols to link to pthreads only if the final app
is threaded and not force the thread dependancy systematically to the apps.
