I'm trying to build xulrunner version 2.0 (sources downloaded from mozilla ftp site) but I keep getting some undefined references when trying to create libxul.so. I tried version 10.0 but same results.
I'm building on Archlinux, but I also get the same error on Ubuntu from the VM I downloaded from mozilla site.
Prior to build xulrunner, some modifications were required in order to build:
https://hg.mozilla.org/mozilla-central/rev/effb4811409b
https://hg.mozilla.org/mozilla-central/rev/87a5ed480992
needed to create an empty /usr/include/curl/types.h file
file security/coreconf/Linux3.16.mk does not exist : copy Linux2.6.mk to Linux3.16.mk
The .mozconfig I'm using:
mk_add_options AUTOCONF=autoconf-2.13
mk_add_options PYTHON=/usr/bin/python2
mk_add_options MOZ_CO_PROJECT=xulrunner
mk_add_options MOZ_OBJDIR=#topsrcdir#/obj-xulrunner
ac_add_options --enable-application=xulrunner
ac_add_options --disable-javaxpcom
After about 30 minutes, I get these errors when trying to build libxul.so:

The command line used to create libxul.so does contains the '-lfreetype', and when I look for FT_Done_Face function into libfreetype.so, it is present :
[dev400t#arch mozilla-2.0]$ nm --dynamic /usr/lib/libfreetype.so | grep FT_Done_Face
000000000001b300 T FT_Done_Face
I did add the "-Wl,-t" option to the command line to make sure libfreetype.so could be found: it is found.
What am I missing?
Your freetype2 version is >= 2.5.1. It contains this change http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=fae382076409db198dfbff36ac4cbb97b05b30a1, which is backwards-incompatible as far as Firefox is concerned.
You need to backport the fix from this bug to your source tree: https://bugzilla.mozilla.org/show_bug.cgi?id=944454 or downgrade your libfreetype2.
Firefox sources as of version 26 and later (including 24 ESR) already contain the fix.

I have a sample code temp.c:
#include "win.h"
win.h is in /home/me/Documents/Code/libs/TUI/win.h and has all the declared functions
which functions are defined in some files in /home/me/Documents/Code/libs/TUI/win/[lots of files].c which every file starts with
#include "../win.h"
//functions
So while using gcc -I /home/me/Documents/Code/libs/TUI /home/me/Documents/Code/temp.c -o /home/me/Documents/Code/temp, gcc returns every function used in temp.c declared in win.h as undefined

The problematic functions are all implemented in file_priorite.c.
Any idea?
You need to have
OBJECTS = simulation.o element.o file_priorite.o
Notice that your build log doesn't include file_priorite in any form - that means you're not building/linking against it. Add file_priorite.o to your OBJECTS line.
I am trying to learn the gobject system, so I read some of the documentation on the gnome site and made a simple gobject parented to GObject. I don't wan't to keep running the gcc job every time I want to compile, and I also wanted to learn a build system at the same time. I tried autotools, which I got working to the point where pkg-config searches for gobject-2.0.
To compile my project from the command line, I do: gcc *.c $(pkg-config --cflags --libs gobject-2.0) (I had to take out the extra ticks for formatting). Anyway <--- this command works.
However: gcc $(pkg-config --cflags --libs gobject-2.0) *.c, which SHOULD BE the SAME COMMAND, returns this:
main.c: In function 'main':

Yes, it is the EXACT SAME COMMAND WITH ANOTHER ORDER. I have no clue what's going wrong. Here is how autotools/automake does the build:
gcc -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -g -O2 -lgobject-2.0 -lglib-2.0 -o GObjectTest main.o myobject.o

Is this some quirky gcc compile thing? I tried with clang too no avail, which makes me think that this is a linker problem? I really have no idea, and was hoping that someone out there will. This is pretty frustrating.
Here is the "offending code":
GType a_get_type (void)
{
if (type == 0) {
GTypeInfo info = {
sizeof(AClass),
NULL,
NULL,
(GClassInitFunc) a_class_init,
NULL,
NULL,
sizeof(A),
0,
(GInstanceInitFunc) NULL
};
type = g_type_register_static (G_TYPE_OBJECT,
"AType",
&info, 0);
}
return type;
}
Edit: Here is the output of my autotools build, the make part anyway:
$ make
make all-recursive

Here is the interesting part: replace gcc -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -g -O2 -lgobject-2.0 -lglib-2.0 -o GObjectTest main.o myobject.o with gcc -o GObjectTest main.o myobject.o -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -g -O2 -lgobject-2.0 -lglib-2.0 and it works.
