How to build your own toolchain (on ICS, for non-SSE3 CPUs)

[StefanS]

Dear group.

since the prebuilt ICS toolchain is not ideal for everyone, here is how to build your own:
in "prebuilt", apply patch-prebuilt.patch and in "ndk" apply patch-ndk.patch (modify this as you see fit, e.g. I added "-mno-sse3 -mtune=pentium-m").

Then, in the root of the ICS tree, run "prebuilt/linux-x86/toolchain/i686-android-linux-4.4.3/build-toolchain.sh"

That worked mostly for me, although some packages still seem to use wrong compiler options.

Stefan
P.S.: Let me know if this works, then I'll probably add this information to www.android-x86.org

[Chih-Wei Huang]

The toolchains in honeycomb-x86 doesn't have the issue.
Maybe we should just revert to the old toolchain.

Or, there maybe a simpler solution if you have both
honeycomb-x86 and ics-x86 source tree.
Just create a buildspec.mk, put

TARGET_TOOLS_PREFIX:=$(HC-x86-top)/prebuilt/linux-x86/toolchain/i686-android-linux-4.4.3/bin/i686-android-linux-

I didn't try, but I think it should work.

Hi Stefans,

As per above ,while i am tring  to run "prebuilt/linux-x86/toolchain/

i686-android-linux-4.4.3/build-toolchain.sh",it's not showing any thing for me.please let me know your suggestion to make it work for me.

Regards
Raj

[StefanS]

Hi Raj,

once you have built the toolchain, the script will delete itself. To
do it again, run
cd prebuilt
git checkout linux-x86/toolchain/i686-android-linux-4.4.3/build-toolchain.sh

Hi,

you need to change the compiler settings in the NDK patch. Try
something like "-march=pentium-mmx -mfpmath=387".
Not sure if it will work.

Hi raj,

you didn't apply the patch.
You can now also check my github repository where I have committed a
shell script and the patches which build the toolchain.
See https://github.com/seidler2547/android-x86-ibm-thinkpad-x41t/tree/x86/ics-x86/patches

Yes, that looks good. Even on my 32MBit internet connection it took a
good while to download all the resources, but in total including
download and build it didn't take more than 10 minutes to build.

Hi Raj,

I don't know what else to do. Maybe you need to try manually with
"git clone https://android.googlesource.com/toolchain"
and check if there is an error.

Checking the file above? Probably you're missing a library or package
on your system.

dear stefan...

how to apply those patches

Hi Stefan,

Great !!!...
Its' working fine...finally,i can see ICS -GUI.
Issue :here, i can see initial ICS-GUI image is tilted to +90 degree
from the normal image on screen.what settings needs to be done to get
proper GUI-image

Thanks a lot.
