How to resolve the "Segmentation fault" error message when using CentOS preverify? (OS) (Linux) (CentOS) (Java) (J2ME) (MIDP)

Abstract

The main function of CentOS preverify is to check whether the class which was originally compiled in J2SE can be executed normally in the MIDP device. But even though it is the simplest HelloWorld.class, there can be "Segmentation fault" errors.

Introduction

CentOS preverify execution environment: CentOS 5.1 + J2SE 1.4.2.17 + J2ME CLDC 1.1 + μ Clinux 20070130

For the simplest HelloWorld, the following error message appears when using preverify.

[root@localhost uClinux] #. / preverify-classpath classes.zip-verbose HelloWorld

[Output directory for verified classes: output]

Segmentation fault

Solution

Step 1:

CentOS preverify shows the language family you are currently using

[root@localhost uClinux] # echo $LANG

En_US.UTF-8

Whether you use Chinese or English, this error message appears as long as you use UTF-8.

Step 2:

CentOS preverify is temporarily changed to another language family.

[root@localhost uClinux] # export LANG=en_US.ISO8859-1

[root@localhost uClinux] # echo $LANG

En_US.ISO8859-1

Step 3:

CentOS preverify successfully implements preverify

[root@localhost uClinux] #. / preverify-classpath classes.zip-verbose HelloWorld

[Output directory for verified classes: output]
