一、开发环境
飞凌OK6410
ubuntu-9.10
交叉编译器arm-linux-gcc 4.3.2
sqlite-3.3.6(http://home.51cto.com/apps/download/index.php?s=/Index/index/)
二、移植步骤
ubuntu下root用户登录
1、将sqlite-3.3.6拷贝到目录 /root 下
# cd
2、解压sqlite-3.3.6 并到该目录下建立任意目录如 build
#tar -zxvf sqlite-3.6.22.tar.gz
#cd sqlite-3.6.22
#mkdir build
3、修改sqlite-3.3.6下的 configure
# vi configure
或者
#gedit configure
注释掉下列这些代码
#
if test
"$cross_compiling" =
"yes"; then
# { { echo "$as_me:$LINENO:: error: unable to find a compiler for building build tools" >&5
#echo "$as_me: error: unable to find a compiler for building build tools" >&2;}
# { (exit 1); exit 1; }; }
#fi
# { { echo "$as_me:$LINENO:: error: unable to find a compiler for building build tools" >&5
#echo "$as_me: error: unable to find a compiler for building build tools" >&2;}
# { (exit 1); exit 1; }; }
#fi
#
else
# test "$cross_compiling" = yes &&
# { { echo "$as_me:$LINENO:: error: cannot check for file existence when cross compiling"
>&5
#echo "$as_me: error: cannot check for file existence when cross compiling" >&2;}
# { (exit 1); exit 1; }; }
# test "$cross_compiling" = yes &&
# { { echo "$as_me:$LINENO:: error: cannot check for file existence when cross compiling"
>&5
#echo "$as_me: error: cannot check for file existence when cross compiling" >&2;}
# { (exit 1); exit 1; }; }
#
else
# test "$cross_compiling" = yes &&
# { { echo "$as_me:$LINENO:: error: cannot check for file existence when cross compiling"
>&5
#echo "$as_me: error: cannot check for file existence when cross compiling" >&2;}
# { (exit 1); exit 1; }; }
# test "$cross_compiling" = yes &&
# { { echo "$as_me:$LINENO:: error: cannot check for file existence when cross compiling"
>&5
#echo "$as_me: error: cannot check for file existence when cross compiling" >&2;}
# { (exit 1); exit 1; }; }
4、到刚才你所创建的目录下,创建Makefile文件
# cd build
#../sqlite/configure --disable-tcl --host=arm-linux(
注:这里可能会出现错误,只要把configure的路径改为绝对路径就可以了)
这个时候你所创建的目录下应该有Makefile、libtool等四个文件
5、修改刚刚生成的Makefile文件
修改 BCC = arm-linux-gcc -g -O2
为 BCC = gcc -g -O2
6、由于是移植到arm上,为了在应用程序中引用sqlite3中的API接口,我们需要创建静态库,所以再次需要修改Makefile
修改内容如下:
找到
sqlite3$(TEXE): $(TOP)/src/shell.c .libs/libsqlite3.la sqlite3.h
修改为
sqlite3$(TEXE): $(TOP)/src/shell.c .libs/libsqlite3.a sqlite3.h
找到
-o $@ $(TOP)/src/shell.c .libs/libsqlite3.la \
修改为
-o $@ $(TOP)/src/shell.c .libs/libsqlite3.a \
sqlite3$(TEXE): $(TOP)/src/shell.c .libs/libsqlite3.la sqlite3.h
修改为
sqlite3$(TEXE): $(TOP)/src/shell.c .libs/libsqlite3.a sqlite3.h
找到
-o $@ $(TOP)/src/shell.c .libs/libsqlite3.la \
修改为
-o $@ $(TOP)/src/shell.c .libs/libsqlite3.a \
(
注意:这次编译不会生成sqlite的可执行文件,因为只是为了得到sqlite3.a静态库
,在build目录下找到隐藏目录.libs ,该目录下有sqlite3.a)
8、执行make和make install命令,如下:
# make
# make install
# make install
这时应该不会有错误了,可以在目录 /usr/local 下看到目录 lib bin include
9、修改sqlite3可执行文件的执行权限
#chmod 775 sqlite3
10、将lib目录下的libsqlite3.so、libsqlite3.so.0、 libsqlite3.so.0.8.6 下载到开发板的 lib目录下,将sqlite3下载到 bin 目录下;
11、测试数据库:
a、新建数据库
[rootL-ant]# sqlite3 test.db
SQLite version 3.6.18
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> create table film (number,name);
sqlite> insert into film values (1,'aaa');
sqlite> insert into film values (2,'bbb');
sqlite> select * from film;
1|aaa
2|bbb
sqlite>.quit
[rootL-ant]#
[rootL-ant]# sqlite3 test.db
SQLite version 3.6.18
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> create table film (number,name);
sqlite> insert into film values (1,'aaa');
sqlite> insert into film values (2,'bbb');
sqlite> select * from film;
1|aaa
2|bbb
sqlite>.quit
[rootL-ant]#
//test_sqlite.c
#include
#include
#include
static int callback( void *NotUsed, int argc, char **argv, char **azColName)
{
int i;
for(i=0; i
{
printf( "%s = %s\n", azColName[i], argv [i]);
}
printf( "\n");
return 0;
}
int main( int argc, char **argv)
{
sqlite3 *db;
char *zErrMsg = 0;
int rc;
if( argc!=3 )
{
fprintf(stderr, "Usage: %s DATABASE SQL-STATEMENT\n", argv[0]);
}
rc = sqlite3_open(argv[1], &db);
if( rc )
{
fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
sqlite3_close(db);
}
rc = sqlite3_exec(db, argv[2], callback, 0, &zErrMsg);
if( rc!=SQLITE_OK )
{
fprintf(stderr, "SQL error: %s\n", zErrMsg);
}
sqlite3_close(db);
return 0;
}
#include
#include
#include
static int callback( void *NotUsed, int argc, char **argv, char **azColName)
{
int i;
for(i=0; i
{
printf( "%s = %s\n", azColName[i], argv [i]);
}
printf( "\n");
return 0;
}
int main( int argc, char **argv)
{
sqlite3 *db;
char *zErrMsg = 0;
int rc;
if( argc!=3 )
{
fprintf(stderr, "Usage: %s DATABASE SQL-STATEMENT\n", argv[0]);
}
rc = sqlite3_open(argv[1], &db);
if( rc )
{
fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
sqlite3_close(db);
}
rc = sqlite3_exec(db, argv[2], callback, 0, &zErrMsg);
if( rc!=SQLITE_OK )
{
fprintf(stderr, "SQL error: %s\n", zErrMsg);
}
sqlite3_close(db);
return 0;
}
arm-linux-gcc test.c -L.libs -I /root/sqlite-3.3.6/build -lsqlite3 -static
解释-I 指向静态库sqlite3.a所在目录,-I指向sqlite3.h 所在目录
c、在超级终端下测试
[rootL-ant]#./test_sqlite test.db
"select * from film"
number = 1
name = aaa
number = 2
name = bbb
[rootL-ant]#
number = 1
name = aaa
number = 2
name = bbb
[rootL-ant]#
