Devive mapper compile error

System is slackware 10, gcc 3.4.0
compiling device-mapper (both 1.00.18 and 1.00.19) give the following error:
--------------------------------------------------------------
ioctl/libdm-iface.c: In function `_flatten':
ioctl/libdm-iface.c:924: error: invalid application of `sizeof' to an incomplete type
ioctl/libdm-iface.c:982: error: dereferencing pointer to incomplete type ioctl/libdm-iface.c:983: error: dereferencing pointer to incomplete type make[1]: *** [ioctl/libdm-iface.o] Error 1
---------------------------------------------------------------

What might be causing this?

TIA

Missing header files or incorrect arguments to 'configure'? Check the instructions in the 'INSTALL' file carefully. (e.g. Most people shouldn't specify a kernel source dir).

Yes , thanks , that was it , I gave a kernel dir as option,

now only vgdisplay -c doesn't work, but maybe it isn't an option anymore?

TIA

Works for me. (Old version perhaps?)
But 'vgs' replaces it with something extremely configurable.
