Ubuntu下使用valgrind所遇問題

1、Valgrind的安裝
a、直接使用sudo apt-get install valgrind
b、valgrind官網下載http://valgrind.org/

#解壓
sudo tar xvf valgrind-3.8.1.tar.bz2 -C /home/worspace/
#安裝
./configure
make
sudo make install

運行：
$valgrind ls -l
出現如下問題：

==18092== Using Valgrind-3.6.1 and LibVEX; rerun with -h for copyright info 
==18092== Command: ls -l

valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination 
valgrind:  cannot be set up.  Details of the redirection are:
 
valgrind:  
 
valgrind:  A must-be-redirected function 
valgrind:  whose name matches the pattern:      index 
valgrind:  in an object with soname matching:   ld-linux.so.2 
valgrind:  was not found whilst processing 
valgrind:  symbols from the object with soname: ld-linux.so.2
 
valgrind:  
 
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, longer term): ask the packagers 
valgrind:  for your Linux distribution to please in future ship a non- 
valgrind:  stripped ld.so (or whatever the dynamic linker .so is called) 
valgrind:  that exports the above-named function using the standard 
valgrind:  calling conventions for this platform.  The package you need 
valgrind:  to install for fix (1) is called
 
valgrind:  
 
valgrind:    On Debian, Ubuntu:                 libc6-dbg 
valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
 
valgrind:   
valgrind:  Cannot continue -- exiting now.  Sorry.

2、解決辦法
仔細閱讀上邊的log信息，
Possible fixes: (1, short term): install glibc's debuginfo
On Debian, Ubuntu:                 libc6-dbg 

ok，執行命令sudo apt-get install libc6-dbg
安裝完成後，問題解決

3、使用方法（valgrind --help）
valgrind --leak-check=yes --show-reachable=yes ls -l
如下是截取的結果分析：

==11283== LEAK SUMMARY:
==11283==    definitely lost: 80 bytes in 2 blocks
==11283==    indirectly lost: 240 bytes in 20 blocks
==11283==      possibly lost: 0 bytes in 0 blocks
==11283==    still reachable: 13,405 bytes in 23 blocks
==11283==         suppressed: 0 bytes in 0 blocks

運行本身的app：
 valgrind --leak-check=full --track-origins=yes --show-reachable=yes ./packapp 0 0 HW9_Multimedia_256MDDR_128MFlash_CTT2_mnt.ini 
結果分析：

==11295== HEAP SUMMARY:
==11295==     in use at exit: 0 bytes in 0 blocks
==11295==   total heap usage: 29 allocs, 29 frees, 70,080,768 bytes allocated

能夠看到堆棧heap分配了29次，釋放了29次。沒有reachable的block 4、遺留的問題 上述關於ld-linux.so.2，non stripped ld.so，應該是關於編譯連接的問題，須要好好看看《編譯原理》了。
