Android source code compilation in ubuntu12.04 Environment

Sudo apt-Get install libncurses5-dev: i386

Package libncurses5-dev: i386 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
Is only available from another source
However the following packages replace it:
Ncurses-Doc libtinfo-Dev

E: Package 'libncurses5-Dev: i386 'has no installation candidate

This problem occurs because of the use of 64-bit systems, cannot use i386, this is 32bit, the network is not successful examples, so try sudo apt-Get install libncurses5-dev: amd64 .. it can be installed, so other i386 problems can be solved in this way.

If you are setting up an environment for Android source code in 64 bits system, the official command may be wrong, use this

$ Sudo apt-Get install git GnuPG flex bison gperf build-essential \ zip curl libc6-dev libncurses5-dev: amd64 x11proto-core-dev \ libx11-dev: amd64 libreadline6-dev: amd64 libgl1-mesa-glx: amd64 \ libgl1-mesa-dev g ++-multilib mingw32 tofrodos \ Python-markdown libxml2-utils unzip tproc zlib1g-dev: amd64 $ sudo ln-S/usr/lib/x86_64-linux-gnu/MESA/libgl. so.1/usr/lib/x86_64-linux-gnu/libgl. so (note the Lib under/usr)

Continue compilation and find the following errors

Libz. so.1 not found

After analysis in this section, is the lack of lib32z1-dev library, installation can be.

The analysis process is as follows for your reference only:

Refference link:

This websit is good for learning)

1. Check which software package provides the library file.
Open the/usr/lib directory when you are idle (because I know that some library files are stored in this directory, which can be used by our developers) and want to see which libraries are in my system.
You can see a libz. So file, and run the following command to view it:

Dpkg-S/usr/lib/libz. So

This command outputs the following information:

Zlib1g-dev:/usr/lib/libz. So

That is, the software package zlib1g-dev in my system provides the libz. So library file.
2. view the detailed information of the software package.
You can run the following command to check what the software package is doing:

Apt-Cache show zlib1g-dev

Part of the output content is:

Description: compression library-development Zlib is a library implementing the deflate compression method found In gzip and PKZIP. This package includes des the development support Files. Bugs: mailto: ubuntu-users@lists.ubuntu.com Origin: Ubuntu

Obviously, this software package provides things related to gzip and PKZIP compression algorithms.

Continue to view the details of the zlib1g-dev package with the following command:
Dpkg-l zlib1g-dev

Compile again to solve the problem! Thank you, Mr. Zhou LIFA.

PS: I would like to try 1bi64z1-dev: i386, but after this is installed, I will not try it. I will give it to future generations.
