How to get GIF support with Perl-GD library?
Can't locate object method "newFromGif"

Hi.

Using Perl v5.8.3 on Linux, I'm trying to install GD interface for Perl (made by Lincoln Stein).
I installed GD, zlib, jpeg-6b and freetype from sources (the very last versions).

When executing script, I get this error message:
-----
Can't locate object method "newFromGif" via package "GD::Image" at ./test.pl line 6.
-------

Line 6:
------
$srcimage = GD::Image->newFromGif("myimage.gif");
------

I know GIF is not supported by official GD libraries, but is it possible to get it via another way?

Thank you very much.

perhaps the gd c library was built without GIF enabled.

you could get the source language version of the library and rebuild it yourself in the appropriate configuration.

And how must I configure libgd to support GIF?


[]# ./configure --help
`configure' configures GD 2.0.34 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']

Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/gd]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

Program names:
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names

X features:
--x-includes=DIR X include files are in DIR
--x-libraries=DIR X library files are in DIR

System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]

Optional Features:
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--disable-dependency-tracking speeds up one-time build
--enable-dependency-tracking do not reject slow dependency extractors
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-static[=PKGS] build static libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--disable-libtool-lock avoid locking (might break parallel builds)
--disable-rpath do not hardcode runtime library paths

Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--with-tags[=TAGS] include additional configurations [automatic]
--with-x use the X Window System
--with-gnu-ld assume the C compiler uses GNU ld default=no
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--with-png=DIR where to find the png library
--with-freetype=DIR where to find the freetype 2.x library
--with-fontconfig=DIR where to find the fontconfig library
--with-jpeg=DIR where to find the jpeg library
--with-xpm=DIR where to find the xpm library

Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
CXX C++ compiler command
CXXFLAGS C++ compiler flags
CXXCPP C++ preprocessor
F77 Fortran 77 compiler command
FFLAGS Fortran 77 compiler flags
XMKMF Path to xmkmf, Makefile generator for X Window System

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Years ago when GD updated to support .png, I emailed Mr. Stein this question his answer was to use an older version of the library. At this point I'm presuming there's no way to support .gif with the GD library. Would ImageMagick better suit your needs?

Or even, do your drawing in .png then pass the image to ImageMagick to convert to .gif? A bit convoluted but it's a solution.

i see that GIF was supported by default as of 2.0.28 so you should be ok there.
try this to see if it "thinks" GIF is supported:
gdlib-config --features

perhaps you have zlib or some other supporting library installed in an unconventional place and therefore would have to specify its include or library path for a configuration.
