* Don't ever build files depending on the directory where they are placed in.Andrey A. Chernov2012-07-241-4/+2
| | | | | | | | | | It is obvious that its modification time will change with each such file builded. This bug cause whole libelf to rebuild itself each second make run (and relink that files on each first make run) in the loop. Notes: svn path=/head/; revision=238741

* Create a symlink to sys/elf32.h, sys/elf64.h, and sys/elf_common.h.Andrew Turner2012-06-241-1/+15
| | | | | | | | | | | | | | | | | | | When building libelf in the bootstrap stage this would include the tree versions of, for example, sys/_types.h. This would work as long as the tree's version of this file was close enough to the system's version of the file. If, however, there was a change in the tree such that the location of a typedef was moved this would cause problems. In this case the version of sys/_types.h in the tree no longer defines __wchar_t and expects it to to be defined in machine/_types.h, however we pick up machine/_types.h from the system and find it is not defined there. The solution is to restrict the parts of sys er include from the tree to those that are needed. This fixes the recent Tinderbox failure. Pointy Hat to: andrew Notes: svn path=/head/; revision=237528

* Build lib/ with WARNS=6 by default.Ed Schouten2010-01-021-2/+0
| | | | | | | | | | | | Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and lower it when needed. I'm setting WARNS?=0 for secure/. It seems secure/ includes the Makefile.inc provided by lib/. I'm not going to touch that directory. Most of the code there is contributed anyway. Notes: svn path=/head/; revision=201381

* Keep shadow copies of the `e_shnum', `e_phnum' and `e_shstrndx'Joseph Koshy2006-12-251-0/+3
| | | | | | | | | | | | | | | | | | members of the ELF Executable Header inside the library-private `struct _Elf' descriptor and only update the underlying Elf{32,64}_Ehdr structure on an elf_update(3) call. These fields of the Ehdr structure are technically `out of bounds' for an application program per the ELF(3) API, but we've seen applications that initialize a new Ehdr structure using memcpy(), messing up the library's invariants. [1] Implement elf_getphnum() and handle ELF objects with more than 64K program header table entries. Reported by: jb [1] Notes: svn path=/head/; revision=165535

Change the M4 templates to wrap an `#if __FreeBSD_version >= NNN'/`#endif' pair around the generated code for each ELF data type, where `NNN' is the OS version where the ELF type was added to the source tree. This change allows cross-builds of old sources on newer FreeBSD systems to work correctly. Problem reported by: ru Notes: svn path=/head/; revision=165317
