Hi!
I could not compile the above piece of code.
maybe I didn't use the correct options. Can you please let me know how
you compiled the code?
Regards,
Vinod

g++ -Wall -Wno-non-virtual-dtor -I/home/user/xulrunner-sdk/include -I/
home/user/xulrunner-sdk/sdk/include `pkg-config --cflags gtk+-2.0` -c
-o embed_xul.o embed_xul.cpp
cc embed_xul.o -L/home/user/xulrunner-sdk/lib -lxpcomglue -lstdc++
`pkg-config --libs gtk+-2.0` -o embed_xul

I have been trying to compile and run the example but I am running
into some difficulties.
The following lines:
XRE_InitEmbeddingType XRE_InitEmbedding;
XRE_TermEmbeddingType XRE_TermEmbedding;
Give me the following errors when compiling:
embed_xul.cpp:27: error: expected initializer before
‘XRE_InitEmbeddingType’
embed_xul.cpp:28: error: ‘XRE_TermEmbeddingType’ does not name a type
If I remove these definitions I am able to compile the application but
I run into some linking issues as follows:
embed_xul.cpp:(.text+0x3e): undefined reference to `XRE_InitEmbedding'
embed_xul.cpp:(.text+0x4d): undefined reference to `XRE_TermEmbedding'
embed_xul.cpp:(.text+0x1ac): undefined reference to
`XRE_InitEmbedding'
embed_xul.cpp:(.text+0x40a): undefined reference to
`XRE_TermEmbedding'
I have tried liking with libembed_base_s.a found under the /embedding/
base directory of the objects folder after building firefox. This
fixes the linking issues but now causes a segmentation fault when
XPCOMGlueLoadXULFunctions is called.
Any help would be greatly appreciated.
Thanks in advance
Danick
Sorry I needed to add -lxul not libembed_base_s.a to remove the
linking problem.

Hello, I managed to perfectly compile your example with
CFLAGS=`pkg-config --cflags gtk+-2.0 gthread-2.0 libxul-embedding-
unstable` -g -Wall
LD_ADD=`pkg-config --libs gtk+-2.0 gthread-2.0 libxul-embedding-
unstable`
minim: minim.cc
g++ -Wno-non-virtual-dtor $(CFLAGS) minim.cc -o minim $(LD_ADD)
on Ubuntu 8.04, with xulrunner-1.9-dev installed, and after changing
the " to < in the include directives
However the app crashes on any browser link clicked.
I do not have the debugging symbols for xulrunner, for a meaningful
backtrace, but are you having the same problem?
If so, what would be the cause? (I saw you're building mozilla from
the source.)
Thanks,
Vlad
