[fedora-arm] Current issues compiling icedtea 1.6 and later for ARM with fc8

Sun Feb 17 12:49:28 UTC 2008

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.
take a peek on : http://icedtea.classpath.org/wiki/BuildRequirements

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

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
http://spindazzle.org/Fedora/libffi-2.99.9-1.fc8.src.rpm
http://spindazzle.org/Fedora/libffi.spec
----
Seventh comming issue: porting of assembler code for ARM  
(implementation of spinlocks and the like)

Well thats it!

Have a great hacking day!
