| 4 | 1. You need 7za and 7zCon.sfx from the p7z-essentials folder to generate the self-extracting jre from the jre. Check in the bitness subfolder (32-bit or 64-bit) appropriate to the target bitness of your self-extracting binary.
|

| 5 |
|
|---|
| 6 | On a mac or linux, you need to compile these two binaries 7za and 7zCon.sfx up yourself by downloading the p7zip source code from online http://p7zip.sourceforge.net/. Compile the source code by first runnng "make" to build the 7za, then run "make sfx" to build the 7zCon.sfx binary.

| 8 | 2. Need the jre for your java version.
|
|---|
| 9 | Java 8 should be used for Expeditee.
|
|---|
| 10 | The jre should be extracted into a folder named jre. Also, don't make it a tar file for Expeditee. But Greenstone expects the jre to be tarred up first.
|
|---|
| 11 |
|
|---|
| 12 | If the self-extracting jre_bin binary should run on a 64 bit machine, use the 64 bit 7za compiled up in the 64-bit subfolder (this will use the associated 64 bit 7zCon.sfx library in the same subfolder). For a 32 bit machine, use the 32 bit 7za in the 32-bit subfolder.
|
|---|
| 13 |
|
|---|
| 14 | 3. Run:
|
|---|
| 15 | ./p7z-essentials/[32|64]-bit/7za a -sfx -mx=9 jre_bin[_x64] /path/to/your-jdk-version/jre[.tar]
|
|---|
| 16 |
|
|---|
| 17 | e.g. for a 32 bit target, you'd run the following on a 32 bit LSB if creating the self-extracting binary for Expeditee:
|
|---|
| 18 | ./p7z-essentials/32-bit/7za a -sfx -mx=9 jre_bin /path/to/your-jdk-version/jre
|
|---|
| 19 |
|
|---|
| 20 | e.g. for a 64 bit target, you'd run the following on a 64 bit LSB, if creating the self-extracting binary for Greenstone:
|
|---|
| 21 | ./p7z-essentials/64-bit/7za a -sfx -mx=9 jre_bin_x64 /path/to/your-jdk-version/jre.tar
|
|---|
| 22 |
|
|---|
| 23 | * -m0=lzma2 is already done automatically, setting the compression mode to lzma2.
|
|---|
| 24 | * -mx=9 set its (compression? speed?) to ultra
|
|---|
| 25 | * the output file name expected by the release-kit is jre_bin for 32 bit linux, jre_bin_x64 for 64 bit linux
|
|---|
| 26 | * -sfx indicates that it will generate a self-extracting binary out of the input file
|
|---|
| 27 | * the "a" indicates it will add the files from the input folder (the /path/to/your-jdk-version/jre in this case) to the output file
