vmware esx server – compile linux kernel / scsi controller/driver problem

by

直接在 vmware esx server 上重裝一台 gentoo linux 的 steps

在這個地方要勾 BusLogic , 在 make menuconfig 要選 BusLogic (簡直是廢話…)

開機後 dmesg | grep scsi 的結果是

解決 error while loading shared libraries 的方法

by

執行程式時, 若遇到

./update_item: error while loading shared libraries: libsqlrclientwrapper-0.40.so.1: cannot open shared object file: No such file or directory

像這樣的錯誤訊息 , 表示程式中所需的 so 檔(share library) 沒找到 , 要修改 /etc/ld.so.conf 加上這個目錄 , 改完要下 ldconfig –v 讓路徑生效

可以用 ldd 看該程式所使用到的 shared library 有那些, 及 lib 路徑

—–

以下是 gentoo 的標準解法 , 其他版本的 linux 則不太相同!!

cat /etc/ld.so.conf   這個檔是由 env-update 產生的 , 所以再繼續看一下 /etc/env.d 下 , 究竟有啥

# ld.so.conf autogenerated by env-update; make all changes to
# contents of /etc/env.d directory
/usr/local/lib
/usr/i686-pc-linux-gnu/lib
/usr/lib/gcc/i686-pc-linux-gnu/4.1.2
/usr/lib/gcc/i686-pc-linux-gnu/4.1.1
/usr/local/firstworks/lib

參考資料, 這是 compile sqlrelay 列出來的 information

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

———————————————————————-

/bin/sh ../../libtool –mode=finish /usr/local/firstworks/lib

PATH=”$PATH:/sbin” ldconfig -n /usr/local/firstworks/lib

———————————————————————-

Libraries have been installed in:

/usr/local/firstworks/lib

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR’

flag during linking and do at least one of the following:

– add LIBDIR to the `LD_LIBRARY_PATH’ environment variable

during execution

– add LIBDIR to the `LD_RUN_PATH’ environment variable

during linking

– use the `-Wl,–rpath -Wl,LIBDIR’ linker flag

– have your system administrator add LIBDIR to `/etc/ld.so.conf’

在 /etc/env.d 下建立一個 90sqlrelay

內容是

LDPATH="/usr/local/firstworks/lib"

再run : env-update , 就看到 /etc/ld.so.conf 多了正確的 lib path 了

[12/6/13 下午4:37:54] RUTEN AA: 到 /usr/lib 找出原生的 .so 檔，應該會是 libsqlrclientwrapper-0.40.so.xxx.xxx
[12/6/13 下午4:38:13] RUTEN AA: ln -s libsqlrclientwrapper-0.40.so.xxx.xxx 到 loss 的 libsqlrclientwrapper-0.40.so.1.0.0
[12/6/13 下午4:38:17] RUTEN AA: 再 ldconfig
[12/6/13 下午4:40:53] RUTEN AA: 可以用 ldconfig -p 看是不是已經把 libsqlrclientwrapper-0.40.so.1 給 load 進來了
