found out why: both libxul-dev and xulrunner-dev are installed ; and I
was building the wrong version. Doh.
There is something fishy with the gtk_moz_embed_get_nsIWebBrowser symbol...
it should be .hidden.
This is what it looks like on amd64:
0000000000000000 *UND* 0000000000000000 .hidden
gtk_moz_embed_get_nsIWebBrowser
and alpha:
00000000000003e0 GPRELHIGH gtk_moz_embed_get_nsIWebBrowser
00000000000003f4 GPRELLOW gtk_moz_embed_get_nsIWebBrowser
It is defined as:
typedef void ( * gtk_moz_embed_get_nsIWebBrowserType) (GtkMozEmbed *embed,
nsIWebBrowser **retval);
extern gtk_moz_embed_get_nsIWebBrowserType gtk_moz_embed_get_nsIWebBrowser
__attribute__((visibility("hidden")));
And the real place where it is defined is dh-gecko-utils.cpp, where,
once compiled, it looks like, on alpha:
00000000000000d0 g O .sbss 0000000000000008 gtk_moz_embed_get_nsIWebBrowser
000000000000066c ELF_LITERAL gtk_moz_embed_get_nsIWebBrowser
0000000000005dc0 REFQUAD gtk_moz_embed_get_nsIWebBrowser
00000000000001b8 REFQUAD gtk_moz_embed_get_nsIWebBrowser
and on amd64:
00000000000000d0 g O .bss 0000000000000008 gtk_moz_embed_get_nsIWebBrowser
00000000000003ee R_X86_64_GOTPCREL
gtk_moz_embed_get_nsIWebBrowser+0xfffffffffffffffc
0000000000005cc2 R_X86_64_64 gtk_moz_embed_get_nsIWebBrowser
00000000000001c8 R_X86_64_64 gtk_moz_embed_get_nsIWebBrowser
FWIW, there are these warnings while building dh-gecko-utils.cpp:
/usr/include/xulrunner-1.9/unstable/./gtkmozembed_glue.cpp:101: warning:
dereferencing type-punned pointer will break strict-aliasing rules.
This warning occurs when preprocessing to get to this code:
static const nsDynamicFunctionLoad GtkSymbolsInternal[] = {
{ "gtk_moz_embed_get_nsIWebBrowser", (NSFuncPtr*)
>k_moz_embed_get_nsIWebBrowser }, { "gtk_moz_embed_get_title_unichar",
(NSFuncPtr*) >k_moz_embed_get_title_unichar }, {
"gtk_moz_embed_get_js_status_unichar", (NSFuncPtr*)
>k_moz_embed_get_js_status_unichar }, {
"gtk_moz_embed_get_link_message_unichar", (NSFuncPtr*)
>k_moz_embed_get_link_message_unichar }, {
"gtk_moz_embed_set_directory_service_provider", (NSFuncPtr*)
>k_moz_embed_set_directory_service_provider }, {
"gtk_moz_embed_set_app_components", (NSFuncPtr*)
>k_moz_embed_set_app_components },
{ 0, 0 }
};
There is a global
gtk_moz_embed_get_nsIWebBrowserType gtk_moz_embed_get_nsIWebBrowser;
defined right before (likewise for other members of this array), and
even before, there is the same definition as for Yelper.cpp (see above).
If this is a toolchain issue, this can surely be worked around by
creating a wrapper function in dh-gecko-utils.cpp to get replace the
gtk_moz_embed_get_nsIWebBrowser in Yelper.cpp.
