Port SQLite in Linux

If you want to talk less, go straight to the topic. Here is the procedure for porting:

1. Transplantation

First download SQLite 3.3.8 from here. The following example shows how to store data in the/root directory.

# Cd/root

# Tar zxvf sqlite-3.3.8.tar.gz

After decompression, A sqlite-3.3.8/subdirectory is generated under the/root directory that contains all the source files and configuration scripts required for compilation. All SQLite3 source code files are located under the sqlite-3.3.8/src/directory. Compiling SQLite3 in a PC environment cannot generate a Makefile file by using the configure script in the sqlite-3.3.8/directory. Instead, you must manually modify the Makefile file. There is a Makefile sample file Makefile. linux-gcc in the sqlite-3.3.8/directory. First, run the following command to copy the file and rename it as Makefile:

# Cp Makefile. linux-gcc Makefile

Next, use vim to open the Makefile file and manually modify the content of the Makefile. First, find the following line in the Makefile file:

TOP = ../sqlite

Modify it:

TOP =.

Find the following line:

TCC = gcc-O6

Modify it:

TCC = arm-linux-gcc-O6

Find the following line:

AR = ar cr

Modify it:

AR = arm-linux-ar cr

Find the following line:

RANLIB = ranlib

Modify it:

RANLIB = arm-linux-ranlib

Find the following line:

MKSHLIB = gcc-shared

Modify it:

MKSHLIB = arm-linux-gcc-shared

Comment out the following line:

TCL_FLAGS =-I/home/drh/tcltk/8.4 linux

Comment out the following line:

LIBTCL =/home/drh/tcltk/8.4 linux/libtcl8.4g. a-lm-ldl

In principle, modifications to Makefile mainly include two aspects: first, replace the compiler and archive tools with the corresponding tools in the Cross tool chain, for example, replacing gcc with arm-linux-gcc, replace ar with ar-linux-ar, and replace ranlib with arm-linux-ranlib. Second, remove the TCL-related compilation options, because by default, bind the Tcl language that will compile SQLite3, but it is not required when porting it to ARM-Linux. Therefore, comment out two lines related to TCL.
