Compiling eLua & ARM Toolchain

For those interested, I made a tutorial explaining how to compile the ARM toolchain and build your custom eLua version with it!

English:

http://www.weekendtinkers.net/Compiling_eLua_en

Portuguese:

Re: Compiling eLua & ARM Toolchain

There is also different gnu-arm toolchain called Summon-arm toolchain which is in use at our RuuviTracker project.
See https://github.com/esden/summon-arm-toolchain

This summon-arm differ on jsnyder's port because it supports hardware floating points.
This is huge performance gain in lua, because Lua uses floating points for all numbers. (except when integer-lua is builded)

You can check if your toolchain supports it by issuing following parameter "--print-multi-lib"

Jsnyder's build:

~/arm-cs-tools/bin$ ./arm-none-eabi-gcc --print-multi-lib

thumb;@mthumb

armv6-m;@mthumb@march=armv6-m

thumb2;@mthumb@march=armv7@mfix-cortex-m3-ldrd

Summon-arm build:

$ arm-none-eabi-gcc --print-multi-lib

thumb/arm7tdmi-s;@mthumb@mcpu=arm7tdmi-s

thumb/cortex-m0;@mthumb@mcpu=cortex-m0

thumb/cortex-m3;@mthumb@mcpu=cortex-m3

thumb/cortex-m4;@mthumb@mcpu=cortex-m4

thumb/cortex-m4/float-abi-hard/fpuv4-sp-d16;@mthumb@mcpu=cortex-m4@mfloat-abi=hard@mfpu=fpv4-sp-d16

Of course those new flags need to be defined in your "conf.py" build script. Floating points are not automatically enabled.

I have following on our RuuviTracker's conf.py:
TARGET_FLAGS = ['-mthumb', '-mcpu=cortex-m4', '-mfloat-abi=hard', '-mfpu=fpv4-sp-d16'] # Hardware floating point. Requires supporting toolchain

Re: Compiling eLua & ARM Toolchain

Gabriel,

Tried your ARM toolchain on Ubuntu 12.04 LTS and encountered some problems:

1 - installing dependencies

libmpfr-dev-dev should be libmpfr-dev

libmpc-dev-y should be libmpc-dev

2 - installing luarocks

luarocks-y should be luarocks

The luarocks install itself went OK. But, I tried

install luarocks lpack

install luarocks luafilesystem

and in both cases I got the following error:

install: cannot stat `luarocks': No such file or directory

3 - making arm-eabi-toolchain

Tried

make install-cross

and got the following:

sudo -u digysol curl -LO http://sourcery.mentor.com/sgpp/lite/arm/portal/package10384/public/arm-none-eabi/arm-2012.03-56-arm-none-eabi.src.tar.bz2

4 - cloning eLua.git

Minor point. Tried the git clone for eLua.git and it asked for a git username and password; whereas the git clone for arm-eabi-toolchain did not need it.

I like your toolchain procedure. It's clean and straightforward. So, any light that you can shed on the above will help.

I refreshed arm-eabi-toolchain from git.

One more thing that had to be done is change the following in the Makefile script:

(before) ifeq($(USER), root)

to

(after) ifneq($(USER), root)

in several places in the script. After that, the make worked and everything ran A-OK.

Apparently, the "before' format added sudo when the user is root (No-no !).

Tried your ARM toolchain on Ubuntu 12.04 LTS and encountered some problems:

1 - installing dependencies

libmpfr-dev-dev should be libmpfr-dev

libmpc-dev-y should be libmpc-dev

Re: Compiling eLua & ARM Toolchain

Good Idea.

BTW, one more thing taht I forgot to mention in my last note.

When setting the PATH environment variable, change the echo command to:

echo PATH=$PATH:$HOME/arm-cs-tools/bin >> ~/.bashrc

No spaces between '~', '/', '.', and 'bashrc'.

I refreshed arm-eabi-toolchain from git.

One more thing that had to be done is change the following in the Makefile script:

(before) ifeq($(USER), root)

to

(after) ifneq($(USER), root)

in several places in the script. After that, the make worked and everything ran A-OK.

Apparently, the "before' format added sudo when the user is root (No-no !).

2013/2/14 Tom Freund <[hidden email]>

Gabriel,

Tried your ARM toolchain on Ubuntu 12.04 LTS and encountered some problems:

1 - installing dependencies

libmpfr-dev-dev should be libmpfr-dev

libmpc-dev-y should be libmpc-dev

2 - installing luarocks

luarocks-y should be luarocks
The luarocks install itself went OK. But, I tried

install luarocks lpack
install luarocks luafilesystem

and in both cases I got the following error:

install: cannot stat `luarocks': No such file or directory

3 - making arm-eabi-toolchain

Tried

make install-cross

and got the following:

sudo -u digysol curl -LO http://sourcery.mentor.com/sgpp/lite/arm/portal/package10384/public/arm-none-eabi/arm-2012.03-56-arm-none-eabi.src.tar.bz2

make: *** [arm-2012.03-56-arm-none-eabi.src.tar.bz2] Error 23

4 - cloning eLua.git

Minor point. Tried the git clone for eLua.git and it asked for a git username and password; whereas the git clone for arm-eabi-toolchain did not need it.

I like your toolchain procedure. It's clean and straightforward. So, any light that you can shed on the above will help.

There is also different gnu-arm toolchain called Summon-arm toolchain which is in use at our RuuviTracker project.

This summon-arm differ on jsnyder's port because it supports hardware floating points.
This is huge performance gain in lua, because Lua uses floating points for all numbers. (except when integer-lua is builded)

You can check if your toolchain supports it by issuing following parameter "--print-multi-lib"

Jsnyder's build:

Of course those new flags need to be defined in your "conf.py" build script. Floating points are not automatically enabled.

I have following on our RuuviTracker's conf.py:
TARGET_FLAGS = ['-mthumb', '-mcpu=cortex-m4', '-mfloat-abi=hard', '-mfpu=fpv4-sp-d16'] # Hardware floating point. Requires supporting toolchain
