Re: gd.trm issue for mingw-gcc-4.3.0 building

[Tatsuro M. <tma...@ya...>]

Hello Ethan and Petr

Thank you for your replies. 

>From the config.log, the configure script of the gd-2.0.36RC1 searches both libiconv and fontconfig.

The gd-2.0.36RC1 is the latest gd source except for that on cvs-trees.

****************
The configure and make were executed using gcc-3.4.5 with the latest mingw runtime and win32api.
(mingw runtime 3.15.1 and w32api-3.13)

./configure --prefix=/usr/local/gd-2.0.36RC1 --disable-shared

Here I refer small part of config.log for gd-2.0.36RC1

configure:21662: gcc -o conftest.exe -g -O2 -DNONDLL -I/mingw/include -I/GnuWin32/include
-I/WinDevTools/include -L/mingw/lib -L/GnuWin32/lib -L/WinDevTools/lib conftest.c 
/GnuWin32/lib/libiconv.dll.a -Wl,-rpath -Wl,/GnuWin32/lib >&5
configure:21668: $? = 0
configure:21689: result: yes

The libiconv used is libiconv-1.9.2 on GnuWin32.

configure:23234: checking for FcInit in -lfontconfig
configure:23269: gcc -o conftest.exe -g -O2 -IC:/Programs/GnuWin32/include/freetype2
-IC:/Programs/GnuWin32/include -DNONDLL -I/mingw/include -I/GnuWin32/include -I/WinDevTools/include
-I/GnuWin32/include/libpng12  -LC:/Programs/GnuWin32/lib -LC:/Programs/GnuWin32/lib -Wl,-s
-LD:/Progra~1/GnuWin32/lib  -L/GnuWin32/bin/lib -L/mingw/lib -L/GnuWin32/lib -L/WinDevTools/lib
conftest.c -lfontconfig  -lfreetype -lpng12 -lz  >&5
configure:23275: $? = 0
configure:23293: result: yes

The fontconfig used is fontconfig-2.4.2 on the GTK web page.
