Hi

The package manager in Ubuntu 8.04 does have all the versions of these
compilers.

To get them in Ubuntu 8.10 (Intrepid) you will need to add the hardy
packages to your repository list.

I added this to the end of the file /etc/apt/source.list (replace “ca” with
your country)

deb http://ca.archive.ubuntu.com/ubuntu/ hardy main restricted universe
multiverse

deb-src http://ca.archive.ubuntu.com/ubuntu/ hardy main restricted universe
multiverse 

deb http://ca.archive.ubuntu.com/ubuntu/ hardy-updates main restricted
universe multiverse 

deb-src http://ca.archive.ubuntu.com/ubuntu/ hardy-updates main restricted
universe multiverse

deb http://ca.archive.ubuntu.com/ubuntu/ hardy-backports main restricted
universe multiverse 

deb-src http://ca.archive.ubuntu.com/ubuntu/ hardy-backports main restricted
universe multiverse

deb http://ca.archive.ubuntu.com/ubuntu/ hardy-updates main restricted
universe multiverse 

deb-src http://ca.archive.ubuntu.com/ubuntu/ hardy-updates main restricted
universe multiverse

Install gfortran-4.1 first (sudo aptitude install gfortran-4.1)

Then install gcc-4.1 and g++-4.1. You will find this will cause an issue as
it defaults to the intrepid versions. Deny the first solution and accept the
second (I think).

You will also find you need to install “libx11-dev” and if you want to use
XML “libxml2” and “libxml2-dev”

----

I just had a peak in the esp-r src/Readme file and it does say that version
4.1 is recommended.

As nearly all new distributions are past version 4.1 (I think), perhaps a
note should be included in the readme that the use of 4.1 also requires:

--compiler_version -4.1, and

that the argument --gcc4 be passed, which it seems simply trades g77 for
gfortran? If this is not declared, make looks for g77-4.1, which does not
exist.

This information could simply go in the “Compilers” section of the Readme.

----

I do recall some unexplained floating point errors with 4.1 which were of
concern for the last year.

Have these been resolved?

We've recently concluded that version 4.1 of the GCC compiler
(gcc/g++/gfortran) is actually more robust than GCC 3.4 (gcc/g++/g77). gcc
4.2.X has produced some unexplained floating-point errors in ESP-r code; all
of these relate to the plant network. We have not yet tested ESP-r using gcc
4.3.X.

Hey Jon and the rest of the usergroup.,

Thank you for your reply to my query. I have a Ubuntu version 8.10 and it
seems like it use gcc, g++ and gfortran version 4.3.2. There are no g77 in
the package manager.

I therefore concluded that I have to install via the command: 

  ./Install -d /opt/esru42 --gcc4

Is it safe to run ESP-r with gcc4 compiler?

I can via the install --help see that I should use the gcc3-version 

because the result obtained with ESP-r binaries build with gcc4 exhibit 

unexplained differences. 

How do I on my machine increase the number of zone and keep a high  

accuracy in the calculations? Can I compile it to gcc3 instead and how do I
do that?

Any help is appreciated.

Best regard

Per Haugaard

A recent question about compiling.  Actually there are more issues in the

warning

message than about XML....

You can get around the XML issue by saying no to the inclusion of XML.

There is a line g77: command not found - this is the fortran compiler and

nothing

is going to happen if it does not find the compiler.  What is likely is
that:

a) your machine is newer and is using the
 gfortran compiler and a newer

   version of the gcc compiler collection.  Check this via the commands

   which gcc

   gcc --version

   which g77

   g77 --version

   which gfortran

   gfortran --version

Sometimes g77 is really g77-3.4 and gcc is really gcc-3.4 in which case

you would install via the command

  ./Install -d /usr/esru --compiler_version -3.4

If your machine has gfortran and is using a version of gcc greater than 4.0

then check the Install --help messages for the syntax of using version 4

compilers.

b) your machine does not have either the g77 or gfortran then you

will need to use your package manager to install the compiler.

Subject: [esp-r]  Compiling ESP-r source code

Dear Usergroup,

I have installed the pre-compiled binary files with out any problems. In an

actual project I need to increase the number of zones to 42 and therefore I
have

tried to compile the ESP-r source code according to this.

During the installation the following warning message 'libxml2 library does

not appear to be installed' is showed and the installation is stopped. Refer

to the below massage:

cd `pwd`/lib; \

    make the_libNoH3KReports

make[1]: Entering directory `/trunk/src/lib'

rm -f TReports_dummy.F ;

ln -s `pwd`/../cetc/h3kreports/TReports_dummy.F . ;

g77  -I../include -I../shocc -I/usr/local/include -I../cetc/h3kreports -DLIN

-DX11    -fno-automatic -finit-local-zero -c TReports_dummy.F

make[1]: g77: Command not found

make[1]: *** [TReports_dummy.o] Error 127

make[1]: Leaving directory `/trunk/src/lib'

make: ***
 [disableXML] Error 2

 -----------------------------------------

 Install: Fatal error.

 Executable disableXML could not be built!

 Installation aborted.

I have looked in the synaptic package manager and I have issued apt-get
install

libxml2 but it is allready installed on the system but does not appear in
the

/src/include or /usr/local/include folder.

Any idea of what has gone wrong in my installation of the source code?

Any help is appreciated :)

Best regards
