Greetings, exciting times ahead!

Icedtea are about to compile nativly on fc8 arm.

I have left my own machine to compile during this weekend, i expect the compilation to take about 60h on my 200Mhz 64Mb ram machine.

the compile of the icedtea source ought to be as simply yet it doesnt ;)

hg clone http://icedtea.classpath.org/hg/icedtea

cd icedtea

./configure

make

I have done some workarounds in order to setup my build environment and to be able to start the compilation.

This mail will point out my current issues, dig in!

Setup the build environment:

Install fc8 on a native arm macine, make sure to add some swapspace.

try installing the reccomended packages

yum install /usr/bin/ecj mercurial cups-devel lesstif-devel libXp-devel libXtst-devel libXi-devel xalan-j2 xerces-j2 \

libXt-devel libgcj freetype-devel gcc gcc-c++ wget java-1.5.0-gcj-devel alsa-lib-devel firefox-devel glib2-devel gtk2-devel \

ant libXinerama-devel libjpeg-devel libpng-devel giflib-devel zlib-devel

for each package that yum cant find, remove tha package name from the command line and try again..

Fist issue: getting the sourcecode with mercurial

The mercurial package found in fc8arm are 0.9.4 icedtea build wants 0.9.5 with forest extensions http://icedtea.classpath.org/wiki/BuildRequirements

0.9.5 mercurial would need updated python to work...

even when i tried to checkout the icedtea source with 0.9.4 mercurial hg command the checkout did never seem to complete (got 2.9mb of .hg data and no more)

Workaround to the mercurial issue:

I simply downloaded the .bz2 snapshots of the icedtea and openjdk directly from the mercurial repositorys webinterface: http://icedtea.classpath.org/hg/

Second issue: eclipse-ecj package not found while installing gcc-java in main fc8arm repositorys

Workaround: i simply downloaded the rpm from http://www.wantstofly.org/~buytenh/RPMS.built.crap/ and ran

rpm -i eclipse-ecj.<version>.rpm

this package does not need bootstrapping as kindly pointed out by Rabeeh Khoury!

now it is possible to install the packages java-1.5.0-gcj-devel and gcc-java with yum

Third issue: firefox webplug build requirements

firefox firefox-devel could not be installed from main repositorys

Workaround to firefox webplug build requirements: run ./configure with switches to skip the compile of the firefox plugins something like --disable-webplug (look in configure.am for correct switch)

Fourth isse: ./configure expects to find gcj in a dir something like /usr/java/gcc-gjc/bin

Workaround: since gcj are located in /usr/bin by default in fc8 i simple made a symlink from

ln -s /usr/bin /usr/java/gcc-gjc/bin

perhaps the gcc-java shoudl populate the java alternatives directory correctly.

install some addisional basic packages required by ./configure like diff

Milestone: now the ./configure works and the compile can begin by simply calling make!

Fifts issue: compiletime

im currently here: having some issues with compile time

My 200Mhz 64Mb ram armv5tejl machine have been compiling for several hours... since the code takes about 6h to compile on a quad 2ghz G5 machine for the PPC platform, i expect my compile time to take atleast 60h. Not for the faint of heart!

possible speedup fix untested:

Sixth probably comming issue: as pointed out by Gary Benson who made the zero code, the compile ought to require libffi

http://gbenson.livejournal.com/14752.html?thread=16288#t16288

good news a libffi source package exists for fc8

https://bugzilla.redhat.com/show_bug.cgi?id=431633

packages approved by Lillian Angel

Seventh comming issue: porting of assembler code for ARM (implementation of spinlocks and the like)

Have a great hacking day!

Subject: question about ARM fedora eclipse-ecj in "RPMS.built.crap"

Hello im currently watching the icedtea source compile natively on a
armv5tel fedora8 host as we speak with the new zero asm patches, have
been compiling for 1,5h now ...

in order to start the build i installed a redora 8 system yet i had to
install the eclipse-ecj rpm from your build dir on
http://www.wantstofly.org/~buytenh/RPMS.built.crap/

so im curious if you have built the eclipse-ecj package using free tools
or if they still needs bootstrapping?

Hi,

I'v built eclipse SRPM from F8 while adding to it the ARM support and some changes to the spec file. I didn't do any bootstrap or use any proprietry tools. It simply builds :)

I can ask Lennert to put the ARM patch and the spec patch somewhere.

Currently eclipse-ecj works fine for me; while the IDE itself is still is not functional (some wiring of arm directories to places where eclipse-platform expects are still missing).
Can you please explain what is missing from your side to fully build icedtea?
