Configuration in a raspberry (make unix)

[Mario Rodríguez Marín]

I have this error:

gcc: error: unrecognized command line  option '-m32'
Makefile: 73: failure in the instructions for the target 'libqlib2.a'
make [2]: *** [libqlib2.a] Error 1
make [2]: it leaves the directory '/home/pi/ew/earthworm_7.7/src/libsrc/qlib2'
makefile.unix: 31: failure in the instructions for the target 'qlib2'
make [1]: *** [qlib2] Error 2
make [1]: it leaves the directory '/home/pi/ew/earthworm_7.7/src/libsrc'
Makefile: 118: failure in the instructions for the target 'unix_libs'
make: *** [unix_libs] Error 2

[Michele Bertoni]

M32 is an option for PC processors. you have to manually remove it from make rules:

follow steps here http://crsengineering.altervista.org/eng/ew_installing_eng.htm and remove flags on makefile on libsrc (or utils), I don't remember.

If it's not urgent, I can place online EW sources for Raspberry.

You can download Raspberry-Pi ready to compile EW from here:

http://crsengineering.altervista.org/downloads/ew_7.7_raspberry.tar.gz

Thanks it works!!!
But I have another question, the configuration in the raspberry is different from that of ubuntu?
I tried the same file in ubuntu 14.04, the compilation is correct but when I tried the startstop comand can't find it.

Mario and others,

I just updated the Earthworm SVN to support ARM (and AARCH64) using gcc.  If you install gfortran, you will get the Hypo2000 modules as well.

There is a new environment/ew_linux_arm.bash script.  You do not specify the bits; it runs the compiler to determine the target architecture.

The version you obtained is 7.7, I believe.  There have been many bug fixes and enhancements since then.  I recommend you use the latest version.

I have a BeagleBone Black running Debian wheezy.  If you encounter any problems, please report them and I will have a look.

Cheers,

Thanks, the turorial in this page http://love.isti.com/trac/ew/wiki/Linux works for the latest version?

[Mario Rodríguez Marín]

Thanks, I still follow the instructions of this page http://love.isti.com/trac/ew/wiki/Linux ?

I am not sure.  I do not use that tutorial.

Here are the steps I use on my BeagleBone Black.  I only have a root account.  I build Earthworm in /opt/earthworm.  That is where I keep the source and binaries.  I use /home/earthworm to run Earthworm.  When I do the svn download, I note the version (rev) number.  That is what I use to set the EW_REV variable.

You should follow the tutorial to install the compilers and subversion that you will need, including gfortran.  The Debian wheezy I use came with gcc installed.  I only had to install gfortran and subversion, as I recall.

Download the latest Earthworm SVN sources and create a tar file snapshot

# cd /opt/earthworm

# rm -f -r earthworm-svn

# svn checkout svn://svn.isti.com/earthworm/trunk earthworm-svn

# EW_REV=rev

# rm -f -r earthworm-7.10-${EW_REV}

# svn export -r ${EW_REV} earthworm-svn earthworm-7.10-${EW_REV}

# tar -cjf earthworm-7.10-${EW_REV}-src.tar.bz2 earthworm-7.10-${EW_REV}

The next two lines are only when you want to start over from the tar file snapshot

# rm -r earthworm-7.10-${EW_REV}

# tar -xjf earthworm-7.10-${EW_REV}-src.tar.bz2

Build the Earthworm binaries from the tar file snapshot

# EW_INSTALL_HOME="`pwd`" \

  EW_INSTALL_VERSION=earthworm-7.10-${EW_REV} \

  source earthworm-7.10-${EW_REV}/environment/ew_linux_arm.bash

# cd earthworm-7.10-${EW_REV}/src

# make clean_unix

# make clean_bin_unix

# make unix &>../../make-linux-arm-${EW_BITS}.log

Look for errors (there should not be any)

# tail ../../make-linux-arm-${EW_BITS}.log

# grep -i ': err' ../../make-linux-arm-${EW_BITS}.log

# grep '[*][*][*]' ../../make-linux-arm-${EW_BITS}.log

The binaries are in /opt/earthworm/earthworm-7.10-${EW_REV}/bin

I don't know where I see the version number (rev).

[Larry Baker]

When you do the svn checkout, it tells you the Rev.

After you have checkout out the Earthworm trunk, svn info will also tell you (Last Changed Rev):

$ cd earthworm-svn

$ svn info

Thanks! But when I set the comand "tail ../../make-linux-arm-${EW_BITS}.log" send me this error.

Are you compiling on Raspberry Pi?  The prompt you show looks like it is from a PC.

You must use ew_linux_arm.bash on Raspberry Pi; you must use ew_linux.bash on PC.

I do not have a Raspberry Pi.  I have a BeagleBone Black.  If you are getting this error on a raspberry Pi, please describe completely the O/S and compiler you are using, and show the commands and the errors from the log file.

PC

[Larry Baker]

Your subject is "Configuration in a raspberry".  Why?  A PC will use ew_linux.bash, not ew_linux_arm.bash.

Please describe what you are trying to do and what O/S you use.

In a comment above, I asked if the configuration of the raspberry works for ubuntu 14.04

[Larry Baker]

Mario,

You have been confusing the issue by mixing computers and operating systems.  Raspberry Pi is hardware—an ARM processor.  Ubuntu is an operating system.  For PCs certainly, I do not know if that is what runs on a Raspberry Pi.  I use neither a Raspberry Pi nor Ubuntu.

If you want to run on a PC, compile for a PC.  That means, use ew_linux.bash.

If you want to run on a Raspberry Pi, compile for ARM.  That means, use ew_linux_arm.bash.

In either case, you will have to install the software development tools you need.  That is gcc, g++, and gfortran.  Plus the 32-bit development libraries if you want to build 32-bit Earthworm on 64-bit Linux.  You don't have to do that if you don't want to.

As I said before, please describe what you are trying to do and what O/S you use if you want more help.
