error using the lvm library in C++

error using the lvm library in C++

[ben scott]

I am still running into trouble using the lvm library. Following the example 
in lvm2app.h I tried:


    dm_list *vgnames;
    lvm_str_list *strl;

    vgnames = lvm_list_vg_names( lvm_pointer );

    dm_list_iterate_items(strl, vgnames) {
        qDebug() << QString( strl->str );
    }

I get this error:

masterlist.cpp:83: error: ?typeof? was not declared in this scope
masterlist.cpp:83: error: expected primary-expression before ?)? token
masterlist.cpp:83: error: expected primary-expression before ?)? token
masterlist.cpp:83: error: expected ?)? before numeric constant
masterlist.cpp:83: error: expected ?)? before ?;? token
etc...

Is it coming from the file libdevmapper.h?

It's easier to get a response if you can supply a standalone snippet of code
when reporting something like this so other people can try compiling it
directly.

First thing to try is to compile with -E and see how the pre-processed output
looks.

Can you post your code?

Attached is a sample C++ hack that works for me with upstream lvm + dm
CVS.  Make sure you are pointing at the right header files and linking
to the correct libraries.
