to run on Linux systems. Since then it has been greatly modified
by various other people.
-If you want to compile strace on a Linux system please make sure
-that you use very recent kernel headers. Strace needs those to get
-the proper data structures used by the kernel, since these can be
-different from the structures that the C library uses. Currently
-you will need a 2.2.7 or newer kernel.

-There are two ways to do this:
-* you can link /usr/include/linux and /usr/include/asm to the corresponding
- directories in your kernel source-tree.
+To complicate things a bit further strace might not compile if you are
+using development kernels. These tend to have headers that conflict with
+the headers from libc which makes it impossible to use them.
-* you can tell make where your kernel sources are. For example if you have your
- kernelsource in /usr/src/linux, you should invoke make like this:
+There are three ways to compile strace with other kernel headers:
+* Specify the location in CFLAGS when running configure
- make CFLAGS=-I/usr/src/linux/include
+ CFLAGS=-I/usr/src/linux/include ./configure
+* you can tell make where your kernel sources are. For example if you
+ have your kernelsource in /usr/src/linux, you can invoke make like
+ this:
+
+ make CFLAGS="\$CFLAGS -I/usr/src/linux/include"
+
+ (the extra \$CFLAGS is there to make sure we don't override any CFLAGS
+ settings that configure has found).
+
+* you can link /usr/include/linux and /usr/include/asm to the
+ corresponding directories in your kernel source-tree.
