Re: [SD4L-user] Mount failed - No such file or directory

[Hans-Ulrich J. <han...@t-...>]

Hello maxl,

thank you for posting, you seem to have come up with a bug
in my kernel driver which hasn't manifested on the Linux
distributions I have built and tested Sd4L so far.

This error is the reason for your later problems. It's a bug
which hasn't shown in conjunction with older kernel versions
(the latest kernel version with which I built Sd4L is 2.6.13).

This error is due to the missing pdflatex in your system.
It merely means that you failed to build the documentation,
so you may ignore it. You may also install pdflatex on your
system in order to get rid of this error.

Yes it is, you failed to build the kernel driver which is
necessary for mounting.

Thank you, for pointing this out. I thought it would fit on most
screens today when I enlarged the size in version 0.9.0. I shall
reduce it again in the next version.

I am going to install Ubuntu 6.06 on a free partition an will build
a new package with the bugs fixed. This, however, will take some weeks.
If you are in a hurry to get Sd4L running on your system I could
send you a patch with private mail. Of course, I would prefer to
test the bugfix myself at first before sending it out. Please, mail
me what you would like.

Best regards,
Ulrich
