Has anyone successfully ported MOZILLA with GTK-DirectFB as backend ???..... I am trying to do it but my compilation is failing after around 60% . It is giving a lot of problems which i would like to share.
Firstly I would like to tell about my system : 1. TI Davinci (arm926ejs + DM6446) ----- target 2. i386 ----- host 3. armv5t ----- toolchain 4. Montavista Linux-2.6.10 ------ OS I have successfully ported GTK and DirectFB and i am able to run the applications without any problem. Problems faced while building Mozilla : 1. Cross Compilation is giving a hell of a problem as the binaries generated for arm are required to build mozilla further. So obviously i get errors like "FILE IN WRONG FORMAT ".......Somehow its a lil silly becoz it totally nullifies the need of Cross-Compilation.......I would love to get some tips on this . 2. To overcome this issue , I got the gnu make on my target system and started Compiling Mozilla on arm itself. Believe me its a very irritating idea coz it takes around 2.5 hrs to build around 50% (obviously the processor speed is a big drawback-----300MHz). My work was going on well until i got messed up with some java utilities which needed "java, javac, javah, jar " tools. I tried to find the Source for JDK which i had planned to cross compile for arm but i was not able to get it on the net freely.........(If someone can share,it will be a big help). The only thing that was close to solving my problem was JDK built for arm4. But somehow it didn't work as for my system i need arm5 built. So here I am, totally stuck up and that too on the verge of getting a gr8 result. I need some help and if that can be provided by some of you experts it will be a big boost. As for any questions on GTK or DirectFB ......anyone and everyone is most Welcome.

I am no expert but I have crosscompiled firefox 1.5 with the directfb patch applied OK. Once you have things configured OK should compile without such problems. Ensure you have libIDL compiled for both your host and target. Makesure your .mozconfig has something along the lines of CROSS_COMPILE=1 LIBIDL_CONFIG=/usr/$MYTARGETCHOST/usr/bin/libIDL-config-2 HOST_LIBIDL_CONFIG=/usr/bin/libIDL-config-2 CXX=$MYTARGETCHOST-gcc CC=$CXX ac_add_options --target=$MYTARGETCHOST substituting $MYTARGETCHOST as appropriate. LIBIDL_CONFIG needs to point to a libIDL-config-2 for the target and HOST_LIBIDL_CONFIG to one for the host. This is essentially what I used - 'CXX=$MYTARGETCHOST-gcc CC=$CXX' may not actually be required but I dont have time to try it without now. You may find you need to update build/autoconf/config.sub, build/autoconf/config.guess, mozilla/nsprpub/build/autoconf/ config.sub, mozilla/nsprpub/build/autoconf/config.guess , directory/c-sdk/config/autoconf/config.sub, directory/c-sdk/config/autoconf/config.guess so that it configures properly for with your CHOST - perhaps take config.sub and config.guess from the root of your gtk+ tree for this. Once it's configuring correctly you should at least find it's not trying to execute binaries built for the target on the host. You'll probably still hit further problems - I may be able to help with these if you post the specific problems. >2.

Perhaps you can disable some stuff in your .mozconfig. I disabled alot of stuff with the intention of re-enabling it if I needed it. I wanted smallest possible build. Hope this is of some help. Be interesting to hear how you get on. -- View this message in context: http://www.nabble.com/Mozilla-porting-over-GTK-DirectFB-on-arm-tf3034...

Sir i tried what you told me but i am still getting the same problem while cross-compiling. The binaries generated for arm are the ones which i386 tries to execute. Can you elaborate me the technique and can you also throw more light as to what changes are needed to be brougth abt in build/autoconf/config.guess, mozilla/nsprpub/ build/ autoconf/config.sub, directory/c-sdk/config/autoconf/config.sub, directory/c-sdk/config/autoconf/config.guess . I am still a beginner and so i need a little more elaborate description of solution. Hope to hear from you soon.
