make bootstrap crashes on incompatible integer to pointer conversion

make bootstrap crashes on incompatible integer to pointer conversion

[Matto Fransen]

Hi,

I am trying to compile Emacs on FreeBSD 14-2 with the latest source from
Git.

These are the first steps:

git pull
git clean -dxf
./autogen.sh
./configure --with-x-toolkit=lucid 
make bootstrap


make boostrap crashes on image.c:

image.c:12358:12: warning: call to undeclared function 'rsvg_handle_get_pixbuf_and_error'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
 12358 |   pixbuf = rsvg_handle_get_pixbuf_and_error (rsvg_handle, &err);
       |            ^
image.c:12358:10: error: incompatible integer to pointer conversion assigning to 'GdkPixbuf *' (aka 'struct _GdkPixbuf *') from 'int' [-Wint-conversion]
 12358 |   pixbuf = rsvg_handle_get_pixbuf_and_error (rsvg_handle, &err);


This doesn't depend on the x-toolkit: either --with-x-toolkit=lucid,
--with-x-toolkit=gtk3, --with-x-toolkit=gtk2, or --with-x-toolkit=no
result in the same error.

It builds fine when configured with: --with-x-toolkit=lucid --without-rsvg

Best regards,

Matto

Thanks, this has been fixed yesterday on the emacs-30 branch, and will
be fixed in a couple of days on master as well.
