[yocto] Exporting variables and extending PATH for Embedded Java

[Davide Soldan]

Environment variable should be defined in /etc/profile
In my build that file is managed by "base-files" recipe. So I wrote a custom recipe "base-files_3.0.14.bbappend" with only a row
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
in the "files" directory I put the "profile" file with the definition of the environment variable.
In that way you should overwrite the original /etc/profile with your custom file...

Hi Guys,


I am planning to install embedded java runtime environment and it just needs the following steps
1. Creation of directory /usr/share/java
2. Copy the files to this directory
3. Creating a environment variable JAVA_HOME=/usr/share/java/ejre1.7.0_10/bin
4. Extending the variable PATH=$PATH:$JAVA_HOME


here is my recipe... The first and second parts are done but I am not able to figure out the 3rd and 4th steps.. Here is my recipe


DESCRIPTION = "Embedded Java from Oracle/Sun"


LICENSE_FLAGS = "oracle_java"
LICENSE = "Oracle_Binary_Code_License_Agreement"
LIC_FILES_CHKSUM = "\
        file://${WORKDIR}/${JDK_JRE}${PV}_${PV_UPDATE}/LICENSE;md5=98f46ab6481d87c4d77e0e91a6dbc15f \

        "


SRC_URI = "file:///home/damarla/yocto/ejre-7u10-fcs-b18-linux-arm-vfp-client_headful-28_nov_2012.gz"


SRCREV ?= "${AUTOREV}"




SRC_URI[md5sum] = "8a6f08f39f916fcdbe0d741d550741ad"
SRC_URI[sha256sum] = "194a522bc27cf4746a0d8ca1e947b13832166ecd6f4f2fbaf5ce1df2a7493d43"


inherit allarch


do_install () {
        install -d ${D}/usr/share/java/
        cp -r ejre1.7.0_10 ${D}/usr/share/java
}




Help is deeply appreciated!
Greets,
Satya
