I've been taking notes (below) of my latest attempt to compile
a simple embedding project (thanks to the uBrowser project
for providing a good example).
At the end is found the output of running the executable
(it finally compiles!). All the ASSERTION and failure to
load files don't look very encouraging.
I don't know if maybe I just happened to check out from CVS (HEAD)
at the wrong time. Otherwise, please let me know what I'm doing wrong.
My system is Ubuntu (Dapper), a Debian-based GNU/Linux system.
Started May 30, 2006.
Obtaining the source
[My last message was blocked because it exceeded the size limit
for message, so I'm eliding this part. In a nutshell, I got
a CVS checkout of HEAD of 'browser,xulrunner'.]
Building XULRunner
Now to build xulrunner, I followed the docs at
http://developer.mozilla.org/en/docs/XULRunner%3ABuild_Instructions .
I based my .mozconfig on their minimal one, plus reading
http://www.mozilla.org/build/configure-build.html and a bit
of http://www.ubrowser.com/howtobuild.php (great example of
an embedding app, by the way!).
mk_add_options MOZ_CO_PROJECT=xulrunner
ac_add_options --enable-application=xulrunner
mk_add_options [EMAIL PROTECTED]@/obj-xulrunner-debug
ac_add_options --disable-javaxpcom
ac_add_options --disable-optimize
ac_add_options --enable-debug
[elision to save space: make -f client.mk build]
Simple test embedding app
I made a Makefile based on one by Doug Turner for the Gecko SDK,
plus information from the ubrowser.vcproj file of the uBrowser project.
Here it is (note: tabs are important in make files).
XX = c++
XR_TARGET_DIR = target
XR_APP_NAME = test
CPPFLAGS += -g -Wall -Wno-non-virtual-dtor -fno-rtti -fno-exceptions

# in every .cpp file. If you're not using GCC remove this line and add
# #include "mozilla-config.h" to each of your .cpp files.

XR_CONF_INCLUDE = -include mozilla-config.h

The test application test.cpp is the following. It is a minimal thing
that uses XRE_InitEmbedding, as shown in uBrowser's embeddedbrowser.cpp
file (embeddedBrowser::init).
// test.cpp
// - using Makefile:
// make
// make target # copies into 'target' directory
#include <string>
#include <iostream>
#include "nsILocalFile.h"
#include "nsXULAppAPI.h" // XRE_InitEmbedding, XRE_TermEmbedding
#include "nsXPCOMGlue.h"
#include "nsCOMPtr.h"
#include "nsStringAPI.h"
int main (int argc, char *argv[]) {
nsresult rv; // nscore.h (via nsXPCOMGlue.h)
// copied from uBrowser
std::string appBaseDir("/home/slanning/mozilla/src/cvs-xulrunner/target");
std::string appDir(appBaseDir);
std::string xulRuntimeDir(appBaseDir);
nsCOMPtr<nsILocalFile> xuldir;
// NS_NewNativeLocalFile is in nsXPCOM.h (via nsXULAppAPI.h)
// PR_FALSE is from sdk/include/prtypes.h (via nscore.h)
rv = NS_NewNativeLocalFile(nsCString(xulRuntimeDir.c_str()),
PR_FALSE, getter_AddRefs(xuldir));
if (NS_FAILED(rv)) {
std::cout << "NS_NewNativeLocalFile failed(xuldir)" << std::endl;
return -1;
}
nsCOMPtr<nsILocalFile> appdir;
rv = NS_NewNativeLocalFile(nsCString(appDir.c_str()),
PR_FALSE, getter_AddRefs(appdir));
if (NS_FAILED(rv)) {
std::cout << "NS_NewNativeLocalFile failed(appdir)" << std::endl;
return -1;
}
rv = XRE_InitEmbedding(xuldir, appdir, nsnull, nsnull, 0);
if (NS_FAILED(rv)) {
std::cout << "XRE_InitEmbedding failed" << std::endl;
return -1;
}
XRE_TermEmbedding();
}
It compiled, at least, with
$ make
$ make target
$ cd target/
$ ./test
