[henry]

Try again after installing demangle.h which is required to compile OpenFOAM.

[agrahn]

Henry,

Is demangle.h the one that comes with libcwd
http://libcwd.sourceforge.net/index.html
?

Alexander

[henry]

We use SuSE and demangle.h installs automatically when the code development package is installed. I do not have any experience with Gentoo.

[rafal]

emerge binutils
should solve the problem
rafal

[agrahn]

Thanks, Rafal, but binutils (2.16.1-r3) is already installed.

Alexander

[agrahn]

Rafal, would you please try to find out to which package demangle.h belongs. This could be done with

equery belongs `locate -r '\<demangle.h\>'`

'equery' is part of the genoolkit package. Of course, package 'slocate' must be installed and the file name data base (updated automatically once a day by updatedb, started via crond) must be present.

Thanks,
Alexander

[rafal]

demangle.h is a part of the sys-devel/binutils.
I untar it and in /include there is demangle.h
rafal

[rafal]

I assume (didnt test) that untaring binutils and
putting demangle.h to /usr/include will solve the
problem(possibly) changing permissions of the file.
maybe you will need to copy in some other dependencies of demangle. binutils 2.16.1-r3 latest stable-should be the most appropriate.
hope this helps.
rafal
PS I dont remember how i did my OF working on Gentoo
but it was definitely gentoo way of doing things

[agrahn]

demangle.h is indeed part of the binutils source file, but doesn't get installed when installing binutils.

I wish I could simply say

emerge openfoam

but

grahn@fwss41:~ $ emerge --search openfoam

[mattijs]

About missing demangle.h : attached a version of error.C (OpenFOAM/db/error/error.C) which does not use demangle.h but uses the cxxabi.h (which is present in most/all gcc installations).

error.C

Tested it on one machine and seems to compile and function ok. Please let me know if there are any problems with it.

[lr103476]

Hi Mattijs,

I replaced the error.C in my OpenFOAM 1.3 installation with your latest version. The following errors occur:

/home/frankl/OpenFOAM/OpenFOAM-1.3/src/OpenFOAM/lnInclude/error.C:97: error: definition of implicitly-declared 'Foam::error::~error()'
/home/frankl/OpenFOAM/OpenFOAM-1.3/src/OpenFOAM/lnInclude/error.C: In static member function 'static void Foam::error::printStack(Foam:stream&)':
/home/frankl/OpenFOAM/OpenFOAM-1.3/src/OpenFOAM/lnInclude/error.C:327: error: 'class Foam::IFstream' has no member named 'getLine'
make: *** [Make/linuxGcc4DPOpt/global.o] Error 1
make: *** Waiting for unfinished jobs....

Any ideas?

Regards, Frank

[henry]

The error.C file Mattijs posted is for OpenFOAM-1.4.

[agrahn]

Thanks, Mattijs, for providing `error.C' which resolves the demangle.h-missing-error.

Next, I had to install the termcap library. Almost no recent software links against it. Hasn't termcap been superseeded by terminfo for ages now?

Now, compilation fails due to a syntax error in file `gambitToFoam.C'. (The recently posted cumulative patch to OpenFOAM-1.4 has been applied.)

Any ideas? Thanks for your help.

Alexander

[gschaider]

Looks like flex generated code that gcc doesn't understand. What does

flex++ -V

say?

[agrahn]

It is actually flex that I am using.

grahn@localhost:~$ flex -V
flex 2.5.33

This is what I found in the flex info manual:

You can also use `flex' to generate a C++ scanner class, using the
`-+' option (or, equivalently, `%option c++)', which is automatically
specified if the name of the `flex' executable ends in a '+', such as
`flex++'. When using this option, `flex' defaults to generating the
scanner to the file `lex.yy.cc' instead of `lex.yy.c'. The generated
scanner includes the header file `FlexLexer.h', which defines the
interface to two C++ classes.

As Allwmake complained about missing flex++, I simply created a hardlink `flex++' pointing to `flex'.

Your encountering what I encountered. Some versions of flex don't like "]]". You need to edit the corresponding .L file and put a space in between the to square closing brackets making it "] ]". You will probably need to do this to a few .L files to get through the compilation.

I also see your using Gentoo (cool)

See my thread here

[agrahn]

Thanks, Conn, very much. Now OpenFOAM compiles till the end.

But the next problem occurs when I try to run the examples from the `Getting Started' section of the README:

grahn@localhost:~/OpenFOAM/grahn-1.4/run/tutorials/icoFoam $ blockMesh . cavity
blockMesh: error while loading shared libraries: /usr/lib/libz.so: invalid ELF header

[benru]

I offer merge this thread & thread "Cumulative patch for OF-1.4" due to discussion of the same problems with code recompilation

FYI:

I am compiling OF 1.4.1 on x86_64 as I type. I have found that using the error.C posted above results in the following compilation error:

If I use the stock error.C the compilation proceeds without any problems.

NB: I built binutils and gcc from scratch, so obviously I am not missing demangle.H
