test suit errors on gcc during pass-2

rangalo · 12-27-2005, 09:51 AM

Hallo all,

i am a new member!

i downloaded the 6.1.1 book (pdf) and following it to make lfs on my slackware-10.2 machine

i have created a special user lfs for it and according to the hint i m working with linux_from_scratch directory..

i could smoothly go upto the pass-2 of the Gcc-3.4.3 installation. when running the test

make -k check.. I have recived following output for libstdc++ test.. the above test (gcc and g++) gave me same result as shown on the url in the book..so i m just pasting where the output starts differing...

i want to know why this result could be differing and what harm does it bring ?

thanks,

They are harmless, some tests are known to fail, RTFM.

hi mr_demilrd,

thanks for ur answer, but I think the main advantage of making LFS is to learn linux and so I just wanted to know why could such error arise and what difference they could make in fucntioning of the newly installed gcc ...

i have read the FM and already started compiling further but I think if I accept everything as it is written, the whole procedure will loose the educational value attached with LFS.. it will be just like another distro where u have to type a lot !!!

any way thanks,

Hardik.
