SQLite for uClinux

SQLite for uClinux
1. Development Tools Need

hardware: Armsys44b0x development board
software: uclinux_armsys_051111.tgz , sqlite 2.8.15, sqlite-2.8.13-uc0 patch

2. Steps

2.1 Download

Download SQLite 2.8.15 from SQLite home page
Download sqlite patch for uclinux sqlite-2.8.13-uc0 patch, no patch for version 2.8.15 found , so we use sqlite-2.8.13-uc0 patch instead and it works well. The URL for the patch is:
http://www.menie.org/georges/uClinux/sqlite-2.8.13-uc0.patch.gz

2.2 Installation
  Extract the sqlite-2.8.15 tarball into your uClinux-dist/user directory:
   tar -zxvf sqlite-2.8.15.tar.gz
  Change the current working path to sqlite source directory and apply the patch
   zcat sqlite-2.8.13-uc0.patch.gz |patch -p1

2.3 Compliation

  In uClinux-dist/user/makefile add the sqlite directory in the list of directories to compile:
  dir_y += sqlite    # this is the line to add

  compile and copy the generated sqlite binary to romfs/bin
  make user_only

3. Test

# cd /var
# sqlite ex1.db
SQLite version 2.8.12
Enter “.help” for instructions
sqlite> create table tbl1(one varchar(10), two smallint);
sqlite> insert into tbl1 values(’hello!’,10);
sqlite> insert into tbl1 values(’goodbye’, 20);
sqlite> select * from tbl1;
hello!|10
goodbye|20
sqlite> .databases
0 main /var/ex1.db
1 temp /var/tmp/sq
sqlite> .schema
create table tbl1(one varchar(10), two smallint);
sqlite> .exit
#
# echo “select * from tbl1;” | sqlite ex1.db
hello!|10
goodbye|20
