[cairo] fatal error: pthread.h: No such file or directory

[YuGiOhJCJ Mailing-List]

Hello,

I try to cross-compile cairo-1.14.2 (because it is a dependency for gtk+-2.24.20).
I do this with my cross-compiler (linux to windows) built with mingw32 and including all these libraries:
binutils-2.24.51
bzip2-1.0.6
expat-2.1.0
fontconfig-2.11.1
freeglut-2.8.1
freetype-2.4.10
gcc-4.9.1
gettext-0.18.2.1
gtk+-1.2.10
libffi-3.0.13
libiconv-1.14
libxml2-2.9.2
libxmp-4.2.8
mesa-9.1.3
mingwrt-3.20.2
sdl-1.2.15
sdl-mixer-1.2.12
sdl-net-1.2.8
sdl-ttf-2.0.11
smpeg-r389
w32api-3.17.2
xmp-4.0.8
zlib-1.2.8

That is how I am doing to cross-compile cairo-1.14.2:
$ PKG_CONFIG_PATH="/usr/i686-pc-mingw32/lib/pkgconfig"
$ tar xvf cairo-1.14.2.tar.xz
$ cd cairo-1.14.2
$ ./configure --prefix=/usr/i686-pc-mingw32 --host=i686-pc-mingw32 --enable-win32 --enable-win32-font --disable-xlib --disable-xlib-xrender --disable-xcb --disable-xlib-xcb --disable-xcb-shm --disable-pthread --without-x
$ make

That is the first time I can't cross compile a library with my cross-compiler.
I don't know exactly why it is looking for the "pthread.h" header because my cross-compiler is not supporting threads and because I have given the "--disable-pthread" option to the configure script.

When I am looking at the /tmp/build/cairo-1.14.2/util/cairo-gobject/Makefile file where the problem is found, I see this rule:
libcairo_gobject_la-cairo-gobject-enums.lo: cairo-gobject-enums.c
	$(AM_V_CC)$(LIBTOOL) $(AM_V_lt) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --mode=compile $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS) $(libcairo_gobject_la_CFLAGS) $(CFLAGS) -MT libcairo_gobject_la-cairo-gobject-enums.lo -MD -MP -MF $(DEPDIR)/libcairo_gobject_la-cairo-gobject-enums.Tpo -c -o libcairo_gobject_la-cairo-gobject-enums.lo `test -f 'cairo-gobject-enums.c' || echo '$(srcdir)/'`cairo-gobject-enums.c
	$(AM_V_at)$(am__mv) $(DEPDIR)/libcairo_gobject_la-cairo-gobject-enums.Tpo $(DEPDIR)/libcairo_gobject_la-cairo-gobject-enums.Plo

I think it is not normal that the "/usr/include/glib-2.0/glib/deprecated/gthread.h" file appears in the error message because this file is part of the headers available in my linux system.
As I am cross-compiling cairo for windows, I should not see that.
Maybe the problem is relative to libtool.

Any idea why I got this error message please?

Thank you.
Best regards.
