libemf deb package somewhere?

[RikoW]

hi,

i'm looking for the ubuntu deb package for libemf (enhanced meta file lib).

It's not in the repositories and I didn't manage to compile it from source, even though i believe I have all the necessary packages installed. Errors I get after ./configure and make:

I found an rpm package, which I , trying my luck, converted to deb via alien and installed. But that wasn't successful either :(

Anybody knows of a secret repository where I might find it (or how to fix the compiling problem above - seems like some standard functions cannot be found ... weired.

Thanks,
Riko

The code seems to be rather old. It even uses windows calls and linkage to wine.

Take these actions.

1) Modify libemf/libemf.h file
$ gedit libemf/libemf.h

and add these line to the header section.
#include <iostream>
#include <function.h>

2) Edit libemf/libemf.cpp
$ gedit libemf/libemf.cpp

Add this line after "#include "libemf.h"

using namespace std;

and remove std:: before all mem_fun1(....) function calls.

A sample:
std::for_each( dc->records.begin(), dc->records.end(),
std::bind2nd( mem_fun1( &EMF::METARECORD::serialize ),
dc->ds ) );

2) Try to configure with gcc-4.x
$ ./configure

If it fails then install gcc-3.4 package and configure for gcc-3.4 compiler suite.
$ CC=gcc-3.4 CXX=g++-3.4 ./configure

No guarantees thou !
Have fun.

Edit: ahh, while I was writing this I saw the post of moma! Thanks :)
The full fix is below.

Why do I need it? emf is a nice scalable format which can be easily import into OOo. With pstoedit I can convert pdf, (e)ps pictures created by various plotting applications ) to emf and use it with OOo. Avoids the fuzziness of gifs or jpegs when you need to scale them.

Ok, and here is now the post I started when moma replied :)

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

ok, solved the compiling problem. Sounded like the programmers were kind of sloppy in inlcudign standard routines which was forgiven by older versions of gcc, which now is much stricter. I had to patch the files libemf/libemf.cpp and libemf/libemf.h:

Found a hint for that on the libemf developers mailing list.

Yep.
