心开天籁

相当于RH的serviceconf
把这记下来是因为现在记忆力下降的厉害
几天前的东西都忘光光了

抓到一个大BUG，
cross compiler处理double值两个32位次序不一样
尽管同样是little endian的系统

恭喜mozilla
祝Open Source 革命成功，打倒微软帝国主义！

历尽千辛万苦，费了九牛二虎之力，终于装上了GENTOO.
持续时间月余。
开始是给下载用的分区太小
然后是SATA硬盘传给kernel的参数不对(应该是root=080x，x是分区号)
期间还有修那个该死的HP机器的破声卡
终于看到了login，哈哈
本来应该写在昨天的blog的，可是昨天太兴奋了

以前改的也存下档吧，省得找不到了
为了查汇编文件输出
Rule.make

man gcc

-E Stop after the preprocessing stage; do not run the compiler proper.
The output is in the form of preprocessed source code, which is
sent to the standard output.
Input files which don’t require preprocessing are ignored.
[snip]
-P Inhibit generation of linemarkers in the output from the preproces-
sor. This might be useful when running the preprocessor on some-
thing that is not C code, and will be sent to a program which might
be confused by the linemarkers.
2.4 kernel /driver/block/blkpg.c 在用了新编译器后有问题，需要输出preprocess信息检查
改/driver/block/Makefile如下
#
# Makefile for the kernel block device drivers.

# Rewritten to use lists instead of if-statements.
#
# Note : at this point, these files are compiled on all systems.
# In the future, some of these should be built conditionally.

技术上讲，这是很容易的
走CDMA1x速度足够了
GPRS也许困难点
如果skype是open source编译一下就可以了
为啥slashdot上那么兴奋？

难道他们俩以前没拿到图灵奖么？
晕，我还以为早拿过了呢
