LSB Result

Introduction

The Linux Standard Base(LSB) was created to lower the overall costs of supporting the Linux platform. By reducing the differences between individual Linux distributions, the LSB greatly reduces the costs involved with porting applications to different distributions, as well as lowers the cost and effort involved in after-market support of those applications. (http://www.linuxfoundation.org/collaborate/workgroups/lsb)

LSB Test Suite support the following architecture.

i486
ia64
ppc32
ppc64
s390
s390x
x86_64

So LSB don't support arm and mips at present time and it will add test suite to support arm and mips possibly in the future.

Analysis of result

Below table shows the failed test cases.

Total failures: The number of total failures after running test. It includes known problems and real failures which should be fixed.
Known problem: Known problem means it is a bug of LSB itself and we can find trace these bugs on http://bugs.linuxbase.org. On link page we give a summary of known problems.
Failures(need to fix) : Real failures we should fix them

x86-32 (emenlw)

We have 4 failures to fix.

Core tests: 2
Xts5 Tests:1

Test	Total failures	Known problem	Failures(need to fix)	Note
Core Tests	12	10	2
Desktop Tests	2	2
Desktop-T2C Tests	2	2
OLVER Core Tests	10	10
Perl Tests	1	1
Printing Tests	1	1
Qt4-Azov Tests	5	5
Xts5 Tests	1		1

ppc(mpc8315e)

We have the following failures(including "unresolved" and "failed") to fix.

Core Tests:
- /tset/ANSI.os/math/... : SIGILL cause 47 unresolved failures.

  It could be caused by the difference of compilation tool between LSB Test Suite and mpc8315e. 
  -Error don't happen when I use LSB Test Suite with version 4.0.
  -I extract test case source codes from lsb test suite and run this code after compiling with compilation tool of mpc8315e,error of illegal instruction don't happen.
  So I think LSB official compilation tool could have some instructions which don't exist on compilation tool of mpc8315e.

OLVER Core Tests:
- OLVER Core Tests can't be finished on mpc8315e-rdb
- We think the reason which make test blocked is the low memory(128M on mpc8315e). Because we re-run the test case which is blocked during OLVER core tests and it can pass successfully. That is to say, if we run the single test case, it will be passed. But we run all OLVER core tests and the whole tests will be blocked. We have ever run OLVER Core Tests for nearly 50 hours and it can't finish.
- lsb-test-olver-core may require about 512Mb of system memory (with an X server and a contemporary desktop running), as well as 2Gb of free disk space to complete a test run. The reference linkage: http://ldn.linuxfoundation.org/lsb/preparing-lsb-distribution-testing
Qt3-Azov Tests:
- Out of memory error cause all of the failures, the following information arise on screen when running Qt3 test suite

- I think this should be limited memory problem
Xpdf Tests:
- SIGILL cause Xpdf failed.
