Merhaba Orhan Bey,
OpenBSD FAQ icinde kernel derlemekle ilgili
olan kismi size bir daha iletmek istedim.

5.2 - Why do I need a custom kernel?
Actually, you probably don't.
A custom kernel is a
kernel built with a configuration file other than the provided GENERIC
configuration file. A custom kernel can be based on -release, -stable or
-current code, just as a GENERIC kernel can be. While compiling your own GENERIC
kernel is supported by the OpenBSD team, compiling your own custom kernel is
not.
The standard OpenBSD kernel configuration (GENERIC) is designed to
be suitable for most people. More people have broken their system by trying to
tweak their kernel than have improved system operation. There are some people
that believe that you must customize your kernel and system for optimum
performance, but this is not true for OpenBSD. Only the most advanced and
knowledgeable users with the most demanding applications need to worry about a
customized kernel or system.
Some reasons you might want or need to build
a custom kernel:
You really know what you are doing, and want to
shoe-horn OpenBSD onto a computer with a small amount of RAM by removing device
drivers you don't need.
You really know what you are doing, and wish to
remove default options or add options which may not have been enabled by default
(and have good reason to do so).
You really know what you are doing, and wish
to enable experimental options.
You really know what you are doing, and have
a special need that is not met by GENERIC, and aren't going to ask why it
doesn't work if something goes wrong.
Some reasons why you should not build a
custom kernel:
You do not need to, normally.
You
will not get a faster system.
You are likely to make a less reliable
machine.
You will not get any support from developers.
You will be
expected to reproduce any problem with a GENERIC kernel before developers take
any problem report seriously.
Users and developers will laugh at you when you
break your system.
Custom compiler options usually do a better job of
exposing compiler problems than improving system performance.
Removing device
drivers may speed the boot process on your system, but can complicate recovery
should you have a hardware problem, and is very often done wrong. Removing
device drivers will not make your system run faster by any noticeable amount,
though can produce a smaller kernel. Removing debugging and error checking can
result in a measurable performance gain, but will make it impossible to
troubleshoot a system if something goes wrong.
Again, developers
will usually ignore bug reports dealing with custom kernels, unless the problem
can be reproduced in a GENERIC kernel as well. You have been
warned.

php + curl
Merhabalar,birkac acemi sorusu var :)
Sun Ultra 1 64bit
makinada Openbsd 3.5 calisiyor.Gayet guzel make word yaptim,kerneli
sadelestirdim.Fakat dun portslardan php kurarken curl'de hata
verdi.
Google'da arastirma yaptigimda curl 7_10.5'e donun diye
yanit aldim.Fakat ports daha degisik bir versionu cekiyor.
Simdi
geliyorum aklima takilan seylere.
1. Ben daha onceden curl 7.12.0
source'dan kendim derleyip /usr/local altina koymustum.Ports php yuklerken neden
buraya bakmaz ? gidip netten eski version curl indirir.Daha once kendi
derledigim curl'ye bakmasini nasil saglayabilirim.
2. Makina kuruldugunda
herseyi kendim derleyeyim istemistim.Php'yi de kendim derlemek istedim.Fakat var
olan bir bug sonucu portsa yoneldim.
php'yi kendim configure ederken bison
yok demisti.bison'u pkg_add ile hazir paketten yerlestirmis ve ikinci
configurede bisonu gordurtmustum.ancak portslardan php yukleyince o yuklenmis
bison'u gormeyip yine netten indirdi. Bunun sebebi ne olabilir.portslardan bir
sey yuklerken ports pkg_add ile yuklenmis seylere bakmaz mi.
3. Son sorum
Openbsd' linkerlariyla ilgili. ldconfig -m ile yeni dizinler eklenmiyor mu ?
Acilista rc.conf icinde shlib_dirs=/etc/rc.conf.local dedigim ve rc.conf.local
dosyasina /usr/local/lib ekledigim halde gormuyor.Bende her paket icin
LD_LIBRARY_PATH set etmek durumunda kaliyorum.Sanirim bir seyler
kaciriyorum.Yardim ederseniz sevinirim.
Selamlar
Orhan
