How to compile Harbour for a Linux ARM machine ?

[Pritpal Bedi]

Hi All

Can someone point me to this direction ?

Best,

Hello student (which I know is in fact a master, I wish I had your knowledge ;)

What i did on my humble Pi running Raspbian

  download harbour as a zip, unpack.
  apt-get install libcups-dev  and other needed development tools
  make

Nothing else needed, runs so well as on a x86_64 machine (just a little slower...)

Hi Pritpal!, try this batch file.works fine!.

Saludos.

Just 2 little remarks:

1) if apt works, no need to use apt-get

2) Not a good idea to make under sudo. Sudo is just needed for make install

A+

What I saw are basic instructions for compiling harbour and i'm sure Pritpal knows them...

I think he can be looking for cross-compiling instructions...

Hi 

 

I think he can be looking for cross-compiling instructions...

Not exactly but similar in nature.

Amazon has just introduced ARM processor empowered Linux instances in addition to x86_64. I launched one with Ubuntu 18.04, apt-get some packages, copy my Ubuntu specific application but it did not run. The application was compiled on x86_64 instance. So I suspected that Harbour build on both processors must be different. That is why I put the question to avoid any surprises I might encounter if I try to compile Harbour.

Thanks Antonio

:-) Thanks though I do not deserve it.

It means I need to compile Harbour and my apps on an ARM machine instead of x86_64. I sit possible to generate ARM binaries while staying on x86_64 machine ?

Thanks mr. Rolaci, your batch should be in harbour(s) site

ypu are a master like mr. Bedi ;-)

ciao !

In android (same archictecture) works.

export HB_PLATFORM="android"

make
sudo make install

You should not encounter big problems compiling harbour on linux ARM... android is a layer over linux after all....

In the past I compiled harbour to run on a ancient set-top-box... its plain c source code helps a lot.

The only problems you may encounter are:

- libraries... depending on the libs you need, expecially for connecting to external software

- time of compilation: I remember reading about 4 hours to compile harbour on a raspberry

Once you have compiled harbour on your arm-based server, you can compile your software to generate a arm-based executable.

To speed things up you may cross-compile harbour on windows or x86-based linux using a cross-compiler toolchain: the executables are for x86 but they create a final executable for arm.

You may find some android-limited infos here: http://www.mozzarellaincarrozza.it/harbour/harbour-and-qt-on-android-part-1/

HI, I create this batch file tested under Raspbian, and it's works perfect...

# previamente ejecutar para darle permisos de ejecucion al batch

# sudo chmod +x build_harbour.sh

sudo apt-get update -y

sudo apt-get install bash git gcc binutils fakeroot debhelper valgrind upx uncrustify subversion -y

sudo apt-get install autoconf automake intltool gdebi gdebi-core git-svn build-essential -y

sudo apt-get install libncurses5-dev libslang2-dev libx11-dev libgpm-dev -y

sudo apt-get install libexpat1-dev libmagic-dev libbz2-dev libsqlite3-dev -y

sudo apt-get install libcurl4-gnutls-dev -y

sudo apt install net-tools -y  

cd ~/

git clone http://github.com/harbour/core.git ~/harbour

cd ~/harbour

export HB_WITH_PCRE=local

rem export HB_USER_CFLAGS="-fPIC"

export HB_WITH_CURL=/usr/include

cd /usr/include

sudo ln -s arm-linux-gnueabihf/curl

cd ~/harbour

make

sudo -E make install

Hi Pritpal,

I'm not even capable of cross-compiling for Linux & Windows on the same x86_64 processor, so I'm sorry, can't help in building for ARM on x86_64.

My projects need Windows and Linux executables to be in sync, they are used in parallel, accessing the same data.
What I do: Development machine is Fedora + VirtualBox. Code on a Fedora partition, available as shared folders for Windows and couple of older Linux distributions virtual machines. So: Single code tree, multiple Harbour installations, but each one compiling for its own arch.

Experimenting with Pi involved transferring code to the little machine, and I was surprised no big issue found.

I know his is not a solution for you needs.
Unless you have some kind of virtual machine manager capable of emulating an ARM processor in parallel with running x86 machines...

Cheers,
António

Hi All

This was easy. I did not read build instructions properly on harbour-core page. Viktor has done a wonderful job. I remained confused because there is no mention of "arm64" -arch on the page. At the end all done by these three lines of shell :

make-arm.sh

==========

export HB_CPU=arm64

export HB_BUILD_NAME=arm64

export HB_HOST_BIN=/develop/harbour/bin/linux/gcc

make

And that's it.

Thanks everybody who helped.
