[linux-lvm] Devive mapper compile error

[Wim Bakker]

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
