| Strace has been ported by Branko Lankester <branko@hacktic.nl> |
| 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 recent kernel headers. Strace needs those to get the proper data |
| structures and constatns used by the kernel, since these can be |
| different from the structures that the C library uses. Currently you |
| will need at least a 2.2.7 or newer kernel. |
| |
| 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. |
| |
| There are three ways to compile strace with other kernel headers: |
| * Specify the location in CFLAGS when running configure |
| |
| 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. |
