Linux DEB package does not set correct permission on jre/lib/jspawnhelper

[AstroPixelProcessor]

I'm submitting a…

• [X ] bug report

Short description of the issue/suggestion:

Linux DEB installer installs a non working java application in terms of being able to load native libs from external library JOGL (OpenGL) that needs to execute a script in user TMP directory to load native libs per platform.

By setting permissions of 755 (rwx,rx,rx) to jspawnhelper in jre/lib/jspawnhelper when the package is installed the issue is solved.

In the RPM packager this is done correctly and explicitely already, so needs to be fixed for the DEB packager.

Please tell us about your environment:

• JavaPackager version: 1.6.5
• OS version: Problem confirmed on Linux Mint 20, Ubuntu 20, It is likely that all DEB distributions are affected.
• JDK version: OpenJDK 17 (Temurin)
• Build tool:
  • [ X ] Maven

Hi @fvarrui ,

After installation of the DEB package, the issue is solved 100% if the user performs:

sudo chmod 755 jre/lib/jspanwhelper

from the package installation folder, so the DEB installer needs to perform this and then all will be okay ;-)

Cheers,

@fvarrui,

in src/main/java/io.github.fvarrui.javapackager/packagers/GernerateDEB you can add the following to the

if (bundleJre) {

}

part to fix it :

// set correct permissions on jre/lib/jspawnhelper

Mapper javaSpawnHelperMapper = new Mapper();
javaSpawnHelperMapper.setType("perm");
javaSpawnHelperMapper.setFileMode("755");
javaSpawnHelperMapper.setPrefix("/opt/" + name + "/" + jreDirectoryName + "/lib");

File jSpawnHelperFile = new File(appFolder, jreDirectoryName + "/lib/jspawnhelper");

Data javaSpawnHelperData = new Data();
javaSpawnHelperData.setType("file");
javaSpawnHelperData.setSrc(jSpawnHelperFile);
javaSpawnHelperData.addMapper(javaSpawnHelperMapper);

dataProducers.add(javaSpawnHelperData);

//

Now the DEB installer produces a working application on Linux Mint and Ubuntu and probably thus on all DEB distributions.

Cheers,
Mabula
