AIX下安装 valgrind问题

cu_baihuihui

这两天在AIX上试着装valgrind-3.3.1,在linux下能装能用。就在AIX下遇到挺多问题
在make 编译过程遇到：
     
ld: 0711-317 ERROR: Undefined symbol: encrypted_pw_passlen
ld: 0711-317 ERROR: Undefined symbol: crypt_r
ld: 0711-317 ERROR: Undefined symbol: max_history_size
ld: 0711-317 ERROR: Undefined symbol: getpass_auto
ld: 0711-317 ERROR: Undefined symbol: max_pw_passlen     

于是我创建一个名为StaticLinkScript的符号表文件，输入：
#!
encrypted_pw_passlen
crypt_r
max_history_size
getpass_auto
max_pw_passlen
编译就能通过了。

但是我在执行程序的时候确报错了:
yb_p690#valgrind
valgrind: can't stat /usr/local/lib/valgrind/ppc64-aix5/memcheck

请问各位这个问题怎么解决？

aix下估计没装crypt相关的库

cu_baihuihui

请问crypt这个库有相关的包可以提供下载吗

cu_baihuihui

env LDFLAGS="-lcrypt" ./configure

不用自己写符号文件了，现在编译，安装都PASS了！
但是还是
yb_p690#valgrind
valgrind: can't stat /usr/local/lib/valgrind/ppc64-aix5/memcheck

我记得valgrind只能在x86的机器上用吧？

我装了gnu sed之后就可以生产memcheck文件了，不会报错了，can't stat /usr/local/lib/valgrind/ppc64-aix5/memcheck
现在的问题是执行就coredump 。dbx调试也看不出什么。
yb_p690(dev):/usr/local/bin>valgrind
Segmentation fault

dbx 调试结果如下

yb_p690#dbx -I /home/dev/wuyh/software/valgrind-3.3.1/coregrind valgrind core

3.3.0,3.3.1可以装成功装在AIX上，3.4.0，3.4.1，3.5.0不能在AIX上装

    这个就是你config的时候指定的那个目录
sh configure --prefix=/yourpath --enable-only32bit

后面你要把编译出来的程序按提示，放在指定的目录
