Configuring with freetype 2 and NOT freetype 1.* installed:

./configure \
--with-gd \
--with-freetype-dir=/usr/local/include/freetype2

results in both HAVE_GD_STRINGTTF and HAVE_GD_STRINGFT being defined in main/php_config.h

This produces this error when trying to use the imagettf*() functions in GD:

"libgd was not built with TrueType font support"

Removing HAVE_GD_STRINGTTF from main/php_config.h before compiling fixes this issue. But of course it should be permanently fixed in autoconf.

Could you check if this works in latest CVS now?

No, still the same problem:

$ grep HAVE_GD_STRING main/php_config.h
#define HAVE_GD_STRINGFT 1
/* #undef HAVE_GD_STRINGFTEX */
#define HAVE_GD_STRINGTTF 1

Gives the same error when compiled and tried with imagettf*().

Sorry, I didn't notice that you're using invalid configure
option value here. --with-freetype-dir expects the
install prefix dir for freetype2.

# ./configure --help |grep freetype
--with-freetype-dir=DIR   GD: Set the path to freetype2 install prefix.

Also, is your GD library compiled with freetype 2?

Yes, GD is compiled with freetype 2. Please observe that everything works perfectly when I edit main/php_config.h manually (removing HAVE_GD_STRINGTTF) before compiling.

It doesn't seem to matter what prefix I enter at --with-freetype-dir, configure reports that it finds freetype 2 anyway. And it apparently works.

In my view there are two issues here:
1. Something is wrong in the autoconf stuff which makes both HAVE_GD_STRINGTTF and HAVE_GD_STRINGFT be defined in main/php_config.h although there is no libttf (freetype 1) on the system and HAVE_GD_STRINGTTF should (as far as I understand) not be defined.

2. The if/else preprocessor stuff in ext/gd/gd.c around line 2765 is strange (or wrong):

# if HAVE_GD_STRINGFT
    error = gdImageStringFT(...);
# endif

# if HAVE_GD_STRINGTTF
    error = gdImageStringTTF(...);
# endif

Shouldn't this be changed to:

#if HAVE_GD_STRINGFT
    error = gdImageStringFT(...);
#elif HAVE_GD_STRINGTTF
    error = gdImageStringTTF(...);
#endif

Or is there a hidden point in both gdImageStringFT() and gdImageStringTTF() being called in sequence if both HAVE_GD_STRINGTTF and HAVE_GD_STRINGFT are defined?

Please check your system for all libg.a (or .so) files.
You most likely have old one there somewhere.
And if this is not the case, send me the libgd.a|so file
so I can check it out myself. (sniper@php.net)

Thank you for noticing that bug (2.).
Fixed in CVS now. I had introduced it myself. :(
