Compiling xpdf
--------------

Xpdf is written in C++ (with a little bit of C).  It should work with
any ANSI-compliant C++ and C compilers.  The systems and compilers
it's been tested with are listed on the xpdf web page.

Xpdf requires the Motif (or Lesstif) toolkit.

The following notes give specific instructions for compiling on
different systems.


**************
***  UNIX  ***
**************

* Install t1lib (if desired).  The resulting library (libt1) and
  include files (t1lib.h and t1libx.h) should be placed somewhere on
  the standard search paths.  Alternatively, when you configure xpdf,
  you can use the following options to tell configure where to find
  the t1lib files:

    --with-t1-library=PATH
    --with-t1-includes=PATH

* Install FreeType 2 (if desired).  WARNING: You must have version
  2.0.5 or newer.  Recent versions of XFree86 ship with an older
  version, which means you'll need to explicitly set include and
  library paths to get the correct version:

    --with-freetype2-library=PATH
    --with-freetype2-includes=PATH

  (With the default installation, the library path is
  /usr/local/include and the include path is
  /usr/local/include/freetype2.)

* Alternatively, you can use FreeType 1.  The resulting library
  (libttf) and include files (freetype/*.h) should be placed somewhere
  on the standard search paths.  If not, when you configure xpdf, you
  can use the following options to tell configure where to find the
  FreeType files:

    --with-freetype-library=PATH
    --with-freetype-includes=PATH

* If you have Motif (or Lesstif) installed in a non-standard place,
  you can use the following options to tell configure where to find
  it:

    --with-Xm-library=PATH
    --with-Xm-includes=PATH

* Run the configure script:

    ./configure

  This should produce a set of makefiles customized for your system.
  The configure script accepts the following options (in addition to
  the usual things accepted by autoconf configure scripts):

    --prefix=PREFIX
        Changes the directory where xpdf is installed.  The default is
        /usr/local.

    --enable-a4-paper
        Switches the default paper size for PostScript output (xpdf
        and pdftops) to A4.  The default is Letter size.

    --enable-no-text-select
        With this option, xpdf will not copy text.  (This is only
        useful on closed systems where the user can't get at the PDF
        file directly.)

    --enable-opi
        Enables support for generation of OPI (Open Prepress
        Interface) comments with pdftops.

    --sysconfdir=DIR
        Look for the system-wide xpdfrc config file in this directory.
        The default is PREFIX/etc.

    --with-appdef-dir=DIR
        Use the specified app-defaults directory.  The default is
        /usr/lib/X11/app-defaults.

* Type 'make'.  This should build the executables:

    xpdf/xpdf
    xpdf/pdftops
    xpdf/pdftotext
    xpdf/pdfinfo
    xpdf/pdffonts
    xpdf/pdftopbm
    xpdf/pdfimages

* If desired, type 'make install' to install the binaries and man
  pages.

The old Makefile.config and Makefiles are no longer provided or
supported.

If you want to run a quick test, there is a tiny PDF file included
with xpdf, as misc/hello.pdf .


*************
***  VMS  ***
*************

* The 'stddef.h' include file which comes with older versions of gcc
  may be missing a definition for wchar_t.  In this case, add the
  following lines:
  -----
  File GNU_CC:[INCLUDE]STDDEF.H;2
   44   /* Wide characters, not yet supported by VAXCRTL [match VAXC's <stddef.
   45   #if !defined(_WCHAR_T) && !defined(_WCHAR_T_)
   46   typedef unsigned int wchar_t;
   47   #endif
   48   #define _WCHAR_T
   49   #define _WCHAR_T_
   50
  -----

* Read the instructions at the top of vms_make.com.

* Type '@vms_make' in the top-level directory.  You'll probably want
  to use some of the options described in the file.

* The executables will be left in '[.xpdf]'.

If you want to run a quick test, there is a tiny PDF file included
with xpdf, as misc/hello.pdf .


**************
***  OS/2  ***
**************

Xpdf is known to run under OS/2 with the EMX runtime environment and
XFree86.  Using a proper autoconf port you can generate a valid
configure script version.


***************
***  Win32  ***
***************

The non-X programs (pdftops, pdftotext, pdfinfo, pdffonts, and
pdfimages) will compile with both gcc (from cygwin), djgpp (the
Delorie port of gcc) and Microsoft Visual C++.

With cygwin, the build procedure is the same as for Unix:

  * Open a shell.

  * ./configure

  * make

  * make install

With djgpp:

  * Open a DOS window.

  * ./dj_make

  * djgpp is a DOS/Windows port of gcc, available from
    http://www.delorie.com/

With djgpp, for DOS 6 (instead of Win32):

  * ./dj_make

  * cd xpdf

  * strip pdftops.exe

  * exe2coff pdftops.exe

  * copy /B c:\djgpp\bin\cwsdstub.exe+pdftops pdftops.exe

  * upx pdftops.exe
    - if you want compressed executables

  * and similarly for the other executables

  * cwsdstub.exe comes from djgpp/v2misc/csdpmi5b.zip on any of the
    djgpp ftp mirrors; exe2coff is part of the standard djgpp install

  * upx comes from http://upx.sourceforge.net/

With the Microsoft tools:

  * Open a DOS window.

  * Type "cl".  If you get the message "Bad command or file name", you
    must run VCVARS32.BAT. (The location of this BAT file can be
    determined with Explorer.)

  * Type "ms_make"
