2006.03.16 18:55 "[Tiff] REPORT: Warning Messages in compile (Re: New libtiff release)", by Norihiko Murase


I tried building the CVS snapshot obtained on Mar 17 02:08 (JST). Some warning messages were printed when the following files were compiled:

  1. libtiff/tif_dirinfo.c
  2. libtiff/tif_jpeg.c
  3. libtiff/tif_ojpeg.c
  4. tools/fax2tiff.c
  5. tools/tiff2pdf.c
  6. contrib/addtiffo/tif_overview.c

No compile error was occurred.

The information of the operating system on which I built is:

    % uname -a

    FreeBSD ***** 4.11-RELEASE FreeBSD 4.11-RELEASE #0: Tue May  3 02:00:46 JST 2005     root@*****:/usr/src/sys/compile/*****  i386

    % which gcc
    % gcc --version

The options specified in executing the configure script is:

    --enable-jpeg --enable-old-jpeg
