PHP Bug Type: Compile Failure
Bug description: Compile fails when using native libGD vs. built-in GD library
Description:
------------
Compiling 4.3.10 with libGD (not the included GD library) without Freetype
resulted the following error:
lclient -lgd -lpng -lz -lz -lm -ldl -o sapi/cgi/php
ext/gd/gd.o: In function `zm_deactivate_gd':
ext/gd/gd.o(.text+0x8933): undefined reference to `gdFreeFontCache'
*** Error code 1
This is similar to several other reported, yet never resolved (really)
bugs (ex. 24310).
Here is the story... libGD (2.0.33) now defines a function (dealing with
FreeType) even if you don't have FreeType installed. The function just
returns a nice error message stating as much :-). So, when the configure
script for PHP tried to determine if the function was included in GD (so
it could set up an ifdef statement) it found it and assumed you have
Freetype support. Unfortunately there really isn't ay FreeType support so
the function (gdFreeFontCache) it tried to include (only included if you
have FreeType support) caused the compile to fail with an undefined
reference error. The solution was to do a better job with the ifdef
statement within the gd.c source file.
I tried to do some "tricky" stuff in the configure script. But, it's
really stupid and only cares if the damn code snippit compiles, not if it
actually returns an error, or not.
I guess you might be able to change the config script to look for
gdFreeFontCache() instead of gdImageStringFT() but I just added some more
rules to one of the ifdef statements in gd.c to fix things, just in case
the test for gdImageStringFT() for other "more useful" things.
Here is the patch to etc/gd/gd.c
Apply with patch -p0 < gd.patch
vs: {94} % more gd.patch
