make.conf配置优化的疑问

linyin

我的CPU是C2.0 MOBILE,这属于什么级别的CPU类型呢?pentium4?

我的make.conf配置文件:
CPUTYPE=pentium4
CFLAGS= -O -pipe
CFLAGS+= -maccumulate-outgoing-args -minline-all-stringops
CXXFLAGS+= -fmemoize-lookups -fsave-memoized
KERNCONF=FreeBSD
NO_CVS=true
NO_BLUETOOTH=true
NO_GDB=true
NO_PF=true
NO_LPR=true
NO_I4B=true
NOINET6=true
NO_SENDMAIL=true
NO_IPFILTER=true
NOGAMES=true
NO_BIND=true
NO_BIND_DNSSEC=true
NO_BIND_ETC=true
NO_BIND_LIBS_LWRES=true
NO_BIND_MTREE=true
NO_BIND_NAMED=true
NO_BIND_UTILS=true
WITH_GTK2=yes
WITHOUT_MAILNEWS=yes
WITHOUT_COMPOSER=yes
WITHOUT_LDAP=yes
WITHOUT_CHATZILLA=yes
WITHOUT_XMLTERM=yes
WITH_GLX=yes
WITH_TTF_BYTECODE_ENABLED=yes
WITH_OPTIMIZED_CFLAGS=yes
WITH_OPTIMIZED_CXXFLAGS=yes
WITH_OPTIMIZE=yes

我在其中已经明确的让gdb sendmail之类的文件不要编译入world,但make buildworld后,sendmail仍然存在(没有进入单用户模式安装系统)
当从新编译好world后(make buildworld;make buildkernel;make installkernel)进入单用户模式,make installworld失败.

另外在编译Xorg的时候也有错误发生  =(

1、编译器选项

CPUTYPE=athlon-xp
##本人使用AthlonXP 2500+，不同的CPU请参考man make.conf

CFLAGS+= -mfpmath=sse -mmmx -msse -m3dnow -maccumulate-outgoing-args
-minline-all-stringops
......
CXXFLAGS+= -fmemoize-lookups -fsave-memoized

我的P3使用了CXXFLAGS+= -fmemoize-lookups -fsave-memoized不能make buildworld。用原来默认的可以！

优化参数都是gcc的，在linux上用O3普遍可以。fb用O2都有些危险，O1吧各位
可以参考
http://wiki.gentoo.org.tw/mediawiki/index.php/HOWTO_CFLAG
http://wiki.gentoo.org.tw/mediawiki/index.php/Desktop_cflags
不同版本的gcc，可用参数也有些小差别，类似 http://gcc.gnu.org/onlinedocs/gcc-3.4.4/gcc/Optimize-Options.html#Optimize-Options ； http://gcc.gnu.org/onlinedocs/gcc-3.4.4/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options
http://gcc.gnu.org/onlinedocs/gcc-3.3.5/gcc/Optimize-Options.html#Optimize-Options ； http://gcc.gnu.org/onlinedocs/gcc-3.3.5/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options

[quote]原帖由 "剑心通明"]make.conf我都是只改一下ports的ftp地址，其他的选项都不用，这样肯定不会出问题的，呵呵[/quote 发表：


我也是

我第一次就是参照它的
但是如果按照他的优化,MAKE WORLD后根本不能INSTALLWORLD

所以我根本就不做那个优化的，以前加过一次，通不过，relaxBSD是做了优化编译的，所以有些机器装不上

我说哪，他的relaxBSD我怎么装不上哪，原来是作了优化，唉。。。
