Automatically find so dependent

First, script writing

When adapting the system, you need to find some dependent files, manual use of Winhex or UltraEdit to find a very troublesome.

So I wrote a shell script to get these dependencies in batches.

Under the Linux system, save the following as Getneed.sh

8. printf "Put this shell to system folder\n"
10. printf "**************************************\n"
14. function Getneed ()
16. {
18. Echo ' <<<<<<getting need for ' >>>>>> '
20. Case $ in
22. LIB/HW)
24. Name=lib_hw
26. ;;
28. Vendor/bin)

32. ;;
34. Vendor/lib)
36. Name=vendor_lib
38. ;;
40. VENDOR/LIB/HW)
42. Name=vendor_lib_hw
44. ;;
46. *)
48. Name=$1
50. ;;
52. Esac
56. if [!-D $];then
58. printf "can ' t find $ folder!\n"
60. Else
62. LS $1-p | grep [^/]$ > Info_$name.txt
64. Cat Info_$name.txt |while Read line
66. Do
68. echo "Getting Need for" $line
70. echo $line >> Need_$name.txt
72. Objdump-x $1/$line | grep "NEEDED" >> need_$name.txt
74. echo "*************************************" >> need_$name.txt
76. Done
78. RM info_$name.txt
80. Fi
82. }
86. Getneed bin;
88. Getneed Lib;
90. Getneed LIB/HW;
92. Getneed Vendor/bin;
94. Getneed Vendor/lib;
96. Getneed VENDOR/LIB/HW;
98. printf "**********completed!**********\n"

Ii. Description of Use

The following operations are done under Linux (operating under Linux ext3 or EXT4 file systems), first ensure that your Linux has objdump this program

Unzip the ROM and copy the getneed.sh to the system directory

Open the shell and navigate to the system directory. #先给权限chmod a+x getneed.sh to execute again./getneed.sh

After execution, the need_xxx.txt generated in the directory is a batch-listed dependency file

If the file does not contain needed, there is no dependency on the file, or it cannot be recognized by objdump

How to interpret (example):

ADB NEEDED libc.so NEEDED libstdc++.so NEEDED libm.so

*************************************

This paragraph means:

ADB this program, need libc.so, libstdc++.so, libm.so these three files

========================================================================================

Additional knowledge:

Sometimes lacks lib, does not prompt the file name, but prompts a string for example: _zn3net15

At this point, you can find it by this command.

Grep-r "_zn3net15" *
