Sqlite4java on Raspberry Pi

Question

I want to use my java project on Raspberry Pi. This code depends on sqlite4java which uses native implementations for many platforms including arm processors link .

The problem is that java can't load required sqlite wrapper for arm processor. I was doing the follows:

1. Copied all version (tried one by one) of precompiled libraries ( libsqlite4java-linux-armv5te.so , libsqlite4java-linux-armv7a.so , libsqlite4java-linux-arm.so ) which I renamed to libsqlite4java-linux-arm.so .

2. Command java -Djava.library.path=. -jar sqlite4java.jar -d java -Djava.library.path=. -jar sqlite4java.jar -d gives output:

    140213:092447.509 FINE [sqlite] Internal: loading library 140213:092447.536 FINE [sqlite] Internal: java.library.path=. 140213:092447.538 FINE [sqlite] Internal: sqlite4java.library.path=null 140213:092447.541 FINE [sqlite] Internal: cwd=/home/pi/sqlite4java-282/. 140213:092447.544 FINE [sqlite] Internal: default path=/home/pi/sqlite4java-282 140213:092447.554 FINE [sqlite] Internal: forced path=null 140213:092447.558 FINE [sqlite] Internal: os.name=linux; os=linux 140213:092447.562 FINE [sqlite] Internal: os.arch=arm 140213:092447.575 FINE [sqlite] Internal: trying to load sqlite4java-linux-arm from /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so 140213:092447.596 FINE [sqlite] Internal: cannot load sqlite4java-linux-arm from /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: java.lang.UnsatisfiedLinkError: /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: cannot open shared object file: No such file or directory 140213:092447.605 FINE [sqlite] Internal: trying to load sqlite4java-linux-arm 140213:092447.617 FINE [sqlite] Internal: cannot load sqlite4java-linux-arm: java.lang.UnsatisfiedLinkError: /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: cannot open shared object file: No such file or directory 140213:092447.622 FINE [sqlite] Internal: trying to load sqlite4java-linux 140213:092447.627 FINE [sqlite] Internal: cannot load sqlite4java-linux: java.lang.UnsatisfiedLinkError: no sqlite4java-linux in java.library.path 140213:092447.638 FINE [sqlite] Internal: trying to load sqlite4java 140213:092447.642 FINE [sqlite] Internal: cannot load sqlite4java: java.lang.UnsatisfiedLinkError: no sqlite4java in java.library.path 140213:092447.645 FINE [sqlite] Internal: trying to load sqlite4java-linux-arm-d 140213:092447.660 FINE [sqlite] Internal: cannot load sqlite4java-linux-arm-d: java.lang.UnsatisfiedLinkError: no sqlite4java-linux-arm-d in java.library.path 140213:092447.676 FINE [sqlite] Internal: trying to load sqlite4java-linux-d 140213:092447.680 FINE [sqlite] Internal: cannot load sqlite4java-linux-d: java.lang.UnsatisfiedLinkError: no sqlite4java-linux-d in java.library.path 140213:092447.683 FINE [sqlite] Internal: trying to load sqlite4java-d 140213:092447.699 FINE [sqlite] Internal: cannot load sqlite4java-d: java.lang.UnsatisfiedLinkError: no sqlite4java-d in java.library.path Error: cannot load SQLite java.lang.UnsatisfiedLinkError: /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: /home/pi/sqlite4java-282/libsqlite4java-linux-arm.so: cannot open shared object file: No such file or directory at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1957) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1882) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1843) at java.lang.Runtime.load0(Runtime.java:795) at java.lang.System.load(System.java:1061) at com.almworks.sqlite4java.Internal.tryLoadFromPath(Internal.java:337) at com.almworks.sqlite4java.Internal.loadLibraryX(Internal.java:117) at com.almworks.sqlite4java.SQLite.main(SQLite.java:368)

3. Tried to set up LD_LIBRARY_PATH to /usr/lib/arm-linux-gnueabihf and /usr/lib

On given path file exists. I had installed sqlite3 and libsqlite3-dev . I'm using the latest raspbian distro on QEMU emulator:

$ uname -a
$ Linux raspberrypi 3.10.26+ #2 Fri Jan 17 22:13:59 EST 2014 armv6l GNU/Linux

Any help will be useful.

Thanks!

Answer 1

Finally I found solution. I had to build library file on Raspbian. Here are steps:

1. Get sources from here
2. Get sqlite_wrap.c file from here
3. Put sqlite_wrap.c to sources directory. You need native , sqlite directories and sqlite_wrap.c file there.

4. Create RELEASE file with content:

    #gcc gcc -O2 -DNDEBUG -fpic -DARM -DARCH="ARM" -DLINUX -D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_LITTLE_ENDIAN -fno-omit-frame-pointer -fno-strict-aliasing -static-libgcc -I./sqlite -I/usr/lib/jvm/jdk-7-oracle-armhf/include -I/usr/lib/jvm/jdk-7-oracle-armhf/include/linux -DSQLITE_ENABLE_COLUMN_METADATA -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_FTS3_PARENTHESIS -DSQLITE_ENABLE_MEMORY_MANAGEMENT -DSQLITE_ENABLE_STAT2 -DHAVE_READLINE=0 -DSQLITE_THREADSAFE=1 -DSQLITE_THREAD_OVERRIDE_LOCK=-1 -DTEMP_STORE=1 -DSQLITE_OMIT_LOAD_EXTENSION=1 -DSQLITE_OMIT_DEPRECATED -DSQLITE_OS_UNIX=1 -c ./sqlite/sqlite3.c -o sqlite3.o gcc -O2 -DNDEBUG -fpic -DARM -DARCH="ARM" -DLINUX -D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_LITTLE_ENDIAN -fno-omit-frame-pointer -fno-strict-aliasing -static-libgcc -I./sqlite -I/usr/lib/jvm/jdk-7-oracle-armhf/include -I/usr/lib/jvm/jdk-7-oracle-armhf/include/linux -DSQLITE_ENABLE_COLUMN_METADATA -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_FTS3_PARENTHESIS -DSQLITE_ENABLE_MEMORY_MANAGEMENT -DSQLITE_ENABLE_STAT2 -DHAVE_READLINE=0 -DSQLITE_THREADSAFE=1 -DSQLITE_THREAD_OVERRIDE_LOCK=-1 -DTEMP_STORE=1 -DSQLITE_OMIT_LOAD_EXTENSION=1 -DSQLITE_OMIT_DEPRECATED -DSQLITE_OS_UNIX=1 -c sqlite_wrap.c -o sqlite_wrap.o gcc -O2 -DNDEBUG -fpic -Di586 -DARCH="i586" -DLINUX -D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_LITTLE_ENDIAN -fno-omit-frame-pointer -fno-strict-aliasing -static-libgcc -I./sqlite -I./native -I/usr/lib/jvm/jdk-7-oracle-armhf/include -I/usr/lib/jvm/jdk-7-oracle-armhf/include/linux -DSQLITE_ENABLE_COLUMN_METADATA -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_FTS3_PARENTHESIS -DSQLITE_ENABLE_MEMORY_MANAGEMENT -DSQLITE_ENABLE_STAT2 -DHAVE_READLINE=0 -DSQLITE_THREADSAFE=1 -DSQLITE_THREAD_OVERRIDE_LOCK=-1 -DTEMP_STORE=1 -DSQLITE_OMIT_LOAD_EXTENSION=1 -DSQLITE_OMIT_DEPRECATED -DSQLITE_OS_UNIX=1 -c ./native/sqlite3_wrap_manual.c -o sqlite3_wrap_manual.o gcc -O2 -DNDEBUG -fpic -Di586 -DARCH="i586" -DLINUX -D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_LITTLE_ENDIAN -fno-omit-frame-pointer -fno-strict-aliasing -static-libgcc -I./sqlite -I./native -I/usr/lib/jvm/jdk-7-oracle-armhf/include -I/usr/lib/jvm/jdk-7-oracle-armhf/include/linux -DSQLITE_ENABLE_COLUMN_METADATA -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_FTS3_PARENTHESIS -DSQLITE_ENABLE_MEMORY_MANAGEMENT -DSQLITE_ENABLE_STAT2 -DHAVE_READLINE=0 -DSQLITE_THREADSAFE=1 -DSQLITE_THREAD_OVERRIDE_LOCK=-1 -DTEMP_STORE=1 -DSQLITE_OMIT_LOAD_EXTENSION=1 -DSQLITE_OMIT_DEPRECATED -DSQLITE_OS_UNIX=1 -c ./native/intarray.c -o intarray.o gcc -O2 -DNDEBUG -fpic -Di586 -DARCH="i586" -DLINUX -D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_LITTLE_ENDIAN -fno-omit-frame-pointer -fno-strict-aliasing -static-libgcc -shared -mno-cygwin -Wl,-soname=libsqlite4java-linux-arm.so -o libsqlite4java-linux-arm.so sqlite3.o sqlite_wrap.o sqlite3_wrap_manual.o intarray.o 

5. chmod +x RELEASE and run it ./RELEASE .

6. libsqlite4java-linux-arm.so will be built, you need to copy it in proper path of your application.

This is not a real answer. I've just updated the commands in OP's own answer for the year 2021 and OpenJDK 11:

Please note that you need to install OpenJDK (not only JRE) first.
