[Mldonkey-bugs] [bug #13480] GD libraries not found on FreeBSD

[savannah-bounces]

Follow-up Comment #6, bug #13480 (project mldonkey):

Maybe not yet. It seems the Gd libs are found when using this configure
line:
./configure --enable-ocamlver=3 --with-libiconv-prefix=/usr/local/include
LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include"

However, somehow PNG support is not working. The configure script says:
checking for png_create_read_struct  in -lpng... yes
checking for jpeg_CreateCompress in -ljpeg... yes
checking for gdImageGif in -lgd... yes
checking for gdImagePng in -lgd... no
checking for gdImageJpeg in -lgd... yes
checking compile with gd... yes

But appearently, that png support is crucial, because linking fails:
src/utils/cdk/gdstubs.o(.text+0x29c): In function `ml_image_open_png':
src/utils/cdk/gdstubs.c:151: undefined reference to `gdImageCreateFromPng'
src/utils/cdk/gdstubs.o(.text+0xa0b): In function `ml_save_png':
src/utils/cdk/gdstubs.c:341: undefined reference to `gdImagePng'
src/utils/cdk/gdstubs.o(.text+0xa9b): In function `ml_dump_png':
src/utils/cdk/gdstubs.c:371: undefined reference to `gdImagePngPtr'

I traced it down to be a Gd error though. Relevant parts of the Gd
configure:
checking for libpng12-config... /usr/local/bin/libpng12-config
checking for libpng-config... /usr/local/bin/libpng-config
checking png.h usability... yes
checking png.h presence... yes
checking for png.h... yes
checking for png_create_read_struct in -lpng12... no
configure: WARNING: libpng is required - see http://www.libpng.org/pub/png/

** Configuration summary for gd 2.0.33:

   Support for PNG library:
   Support for JPEG library:         yes
   Support for Freetype 2.x library: yes
   Support for Fontconfig library:   yes
   Support for Xpm library:          yes
   Support for pthreads:             yes

Maybe it is an idea to use GIF instead of PNG anyway? At least when its found
that PNG is not available.
