5There are two main parts to this package: the DRM client library/interface
6(libdrm.so) and kernel/hardware-specific device modules (such as i915.ko).

10Compiling
11---------
12
13By default, libdrm and the DRM header files will install into /usr/local/.
14If you want to install this DRM to replace your system copy, say:
15
16	./configure --prefix=/usr --exec-prefix=/
17
18Then,
19	make install
20
21
22To build the device-specific kernel modules:
23
24	cd linux-core/
25	make
26	cp *.ko /lib/modules/VERSION/kernel/drivers/char/drm/
27	   (where VERSION is your kernel version: uname -f)
28
29Or,
30	cd bsd-core/
31	make
32	copy the kernel modules to the appropriate place

36Tips & Trouble-shooting
37-----------------------
38
391. You'll need kernel sources.  If using Fedora Core 5, for example, you may
40   need to install RPMs such as:
41
42	kernel-smp-devel-2.6.15-1.2054_FC5.i686.rpm
43	kernel-devel-2.6.15-1.2054_FC5.i686.rpm
44	etc.
45
46
472. You may need to make a symlink from /lib/modules/VERSION/build to your
48   kernel sources in /usr/src/kernels/VERSION (where version is `uname -r`):
49
50	cd /lib/modules/VERSION
51	ln -s /usr/src/kernels/VERSION build
52
53
543. If you've build the kernel modules but they won't load because of an
55   error like this:
56
57	$ /sbin/modprobe drm
58	FATAL: Error inserting drm (/lib/modules/2.6.15-1.2054_FC5smp/kernel/drivers/char/drm/drm.ko): Invalid module format
59
60   And 'dmesg|tail' says:
61
62	drm: disagrees about version of symbol struct_module
63
64   Try recompiling your drm modules without the Module.symvers file.
65   That is rm the /usr/src/kernels/2.6.15-1.2054_FC5-smp-i686/Module.symvers
66   file (or rename it).  Then do a 'make clean' before rebuilding your drm
67   modules.
