- Unpack the ksymoops tar.gz file (silly me, you already did that :).
- Edit the Makefile to set any defaults you want.
- make
- as root, make install
- To compile and link ksymoops, you need bfd.h, libbfd and libiberty. On
- most systems, these are all part of the binutils package so installing
- binutils is all that is required. On Debian systems, bfd.h (at least)
- is in a separate package, binutils-dev.
- Some people have reported problems building ksymoops, with unresolved
- references in libbfd (htab_create, htab_find_slot_with_hash). Try
- http://www.cs.helsinki.fi/linux/linux-kernel/2002-13/0196.html first,
- if that does not work, contact the binutils maintainers. This is not a
- ksymoops problem, ksymoops only uses libbfd. Any unresolved references
- from libbfd are a binutils problem.
- Some distributions get binutils and libbfd/libiberty out of sync during
- the upgrade, and break the link of ksymoops. This has been reported on
- Slackware 8.[01] but other distributions may get it wrong as well. Try
- installing a clean binutils.
- Building ksymoops for cross compile and debugging
- =================================================
- When you are building a kernel using a cross compiler, it may be useful to
- build a dedicated version of ksymoops for this cross compile environment.
- It is not necessary to do so, you can always use the native ksymoops with
- suitable options (e.g. the e, t and a flags), together with environment
- variables KSYMOOPS_NM and KSYMOOPS_OBJDUMP. It may be more convenient to
- build a special version of ksymoops and install it along with the other cross
- compile tools.
- At build time you can specify the CROSS, BFD_PREFIX, DEF_TARGET and DEF_ARCH
- options to make. For example,
- make BFD_PREFIX=/usr/mips64-linux
- DEF_TARGET='"elf64-bigmips"'
- DEF_ARCH='"mips:8000"'
- CROSS=mips64-linux-
- will build ksymoops -
- * using bfd files from /usr/mips64-linux/include and /usr/mips64-linux/lib
- (BFD_PREFIX)
- * the default value for -t will be "elf64-bigmips" (DEF_TARGET)
- * the default value for -a will be "mips:8000" (DEF_ARCH)
- * the result will be installed as /usr/bin/mips64-linux-ksymoops (CROSS)
- * it will default to using /usr/bin/mips64-linux-{nm,objdump} (INSTALL_PREFIX,
- /bin and CROSS).
- Any variable starting with DEF_ takes a string value. These variables go
- through two levels of expansion, shell (use '...' to avoid shell expansion),
- and make commands (prefix " with to preserve " characters).
