Issue #79 new

Compile for ARM

David Irving
created an issue


Could someone please tell me how to cross compile the SQLite-JDBC for the arm processor. I have Ubuntu set up with the toolchain, I just need to know what commants to pass, or what to modify in the makefile?

Thank you very much for any assistance.

    Thanks for your reply. I am still having issues. Here is my notes

    1) install openjdk-6-jdk 2) install all cross-compile tools 3) install maven (found out later) 4) set JAVA_HOME to JDK path (DPKG -L openjdk-6-jdk and look for the base path before the

    /include directory (where jni.h header file is included) 5) Updating Makefile and Makefile.common 6) I've observed CROSS_PREFIX=arm-linux-gnueabi- set in Makefile. Lets make sure that those compilers are installed and the binary references are correct

    arm-linux-gnueabi-g++ arm-linux-gnueabi-g++: fatal error: no input files compilation terminated.

    yep it is!

     --info                        List object formats & architectures

    supported -o <file> Place stripped output into <file> arm-linux-gnueabi-strip: supported targets: elf32-littlearm elf32-bigarm elf32-little elf32-big

    plugin srec symbolsrec verilog tekhex binary ihex

    arm-linux-gnueabi-strip is also installed

    check the cflags used for Arm compilation remove non supported

    silence the deprecated conversion from string contstat to char*


    I am stuck.

    Hi. Yes. I compiled it on a Raspberry Pi. It worked perfectly. I originally wanted to cross-compile from my main intel machine, I added some of the arm target stuff but I still couldn't get it to work as I wrote above. Compiling on the Pi was a quicker way out.

    how did you manage to compile on the Pi? I tried to compile on Raspbian with OpenJDK 6, but had no susccess. I get UnsatifiedLinkErrors during the testing stage of the build process.

    I had to do the following to cross compile for ARM (oops, think my diff is the wrong way around):

    sudo apt-get install curl openjdk-7-jdk maven

    make sure $PATH is set to point to your ARM toolchain.

    export the path to your openJDK... in my case: export JAVA_HOME="/usr/lib/jvm/java-7-openjdk-i386/"

    Add the following lines to the main Makefile, making sure to set your compiler prefix as required: --- Makefile 2015-05-04 15:32:48.388514876 +1200 +++ xerial-sqlite-jdbc-cb3185b14872/Makefile 2014-10-08 21:24:13.000000000 +1300 @@ -91,11 +91,6 @@ linux32: $(MAKE) native OS_NAME=Linux OS_ARCH=i386

    Then to build simply run: make linux-arm OR make linux-armhf depending on your needs.

    Thanks to Taro L. Saito for the advice above.
