compile failed when making building system



  • Hi all,
    I followed the instructions described on documents to set up my building system . However when I compile with make -j1 V=s. I came across errors as below. I checked it on line and could not find a solution to it.

    checking for gij... no
    checking for java... java
    checking for ecj... ecj -warn:-deprecation,serial,unusedImport
    checking if ecj -warn:-deprecation,serial,unusedImport is a version of gcj... no
    checking if ecj -warn:-deprecation,serial,unusedImport works... configure: error: The Java compiler ecj -warn:-deprecation,serial,unusedImport failed (see config.log, check the CLASSPATH?)
    Makefile:89: recipe for target '/home/fan/omega2/build_dir/target-mipsel_24kc_musl-1.1.16/classpath-0.99/.configured_yyyynnnn' failed
    make[3]: *** [/home/fan/omega2/build_dir/target-mipsel_24kc_musl-1.1.16/classpath-0.99/.configured_yyyynnnn] Error 1
    make[3]: Leaving directory '/home/fan/omega2/feeds/packages/libs/classpath'
    package/Makefile:105: recipe for target 'package/feeds/packages/classpath/compile' failed

    /home/fan/omega2/include/toplevel.mk:198: recipe for target 'world' failed
    make: *** [world] Error 2

    I am using virtual box with Ubuntu 18.04.1 LTS.
    Thanks!



  • @Fan-Wu said in compile failed when making building system:

    checking if ecj -warn:-deprecation,serial,unusedImport works... configure: error: The Java compiler ecj -warn:-deprecation,serial,unusedImport failed (see config.log, check the CLASSPATH?)

    Did you check the config.log?

    I'd suggest using the docker image as it is provides a faster pathway to a successful build in my experience, but I understand that there are alternatives and these are the kinds of problems that go along with it.

  • After I install java-wrappers, it is good now. Thanks all!
    sudo apt-get install java-wrappers
