Build broken and code repository

2025-12-09T12:17:58.542000Z

Hello
Sourceforge dropped CVS support so one has to download the repo and create a local repo. Is it possible to switch to svn or git?
I managed to compile the project with debian 13 but I had to do some minor corrections. How should I sent the patch?

#11 configure broken

2020-03-29T19:15:34.637000Z

This was fixed in the source code in january 2006 after the latest pre release:

->tail -144 configure.in | head -11
dnl --- blacklist the too old versions
case "$LIBUSB_VER" in
    0.1.[[0123456]]|0.1.[[36]][[ab]])
    AC_MSG_WARN([
*** You need at least version 0.1.7 of the libusb library for USB support
*** http://sourceforge.net/projects/libusb/
*** If you cannot find the appropriate version, try CVS
        ])
    exit 1 ;;
    *);;

configure broken

2020-03-29T18:36:31.746000Z

As of 29 March 2020, the configure script is broken. The comparison between version of libusb in line 200002:
if test "$LIBUSB_VER" \< "0.1.7"; then
fails to deliver a correct result when comparing to version 0.12.1.
I recommend replacing the above line with:

LIBUSB_VER=$(printf '%s\n2' "0.1.7" | sort -V | head -1)
if test "$LIBUSB_VER" != "0.1.7" ; then

Cheers, Daniela

KMPIO segmentation fault AMD64

2006-12-30T07:15:56Z

Hi,

I compiled KMPIO 0.7.0 for my Debian AMD64 Etch system. Compilation appears to work OK. And running KMPIO works fine. When I click on the check mark button to connect to my MPIO, I see a progress bar for the reading of my MPIO's memory. When it is complete the program crashes with a segmentation fault. (See backtrace below.)

Can anyone offer any suggestion for getting KMPIO to work under AMD64. (MPIOSH works fine but it'd be nice to have the GUI!)

Thanks for reading.

Here is the backtrace from GDB:

DMK 256

2006-02-20T17:41:14Z

hello,
I have DMK 256Mb player ant it not supports well ...
I've tryed versions 0.7 and 0.7.1-pre2 but they not

actualy player recognises and it's possible to read
files from tham, but formatting and uploading not

Killed my fl100!!

2005-02-24T03:33:08Z

I was using mpiosh to transfer songs to my fl100 internal memory
card when mpiosh quit with a segmentation fault. Then the
computer stopped responding to the fl100 and when I unplugged it
from USB it froze up. Now I can't turn it on :(

I think I must have klobbered something important from the
internal memory card but I can't turn it on so I can't communicate
with it from my computer.

It's a real shame because up till that moment the mpiosh had
worked fine with no glitches whatsoever

Failed to read Block.(nread=0xffffffac)

2004-12-14T16:58:18Z

I use Debian unstable, kernel kernel 2.6.8-1-k7 and
hotplug support. Packages mpio libmpio libmpio-dev
libusb-dev kmpio where installed from
http://www.le-seb.org/unofficial-debs/

a) I can start mpiosh or kmpio.

b) I get this error because I haven't connected the
device (obviously, but necessary for troubleshooting)
ERROR: Could not open /dev/usb/mpio

connected and powered up.
could not find MPIO player.

c) When I connect the FL100 to the usb bus, I get this
message on /var/log/messages. It seems like the device
is connected (ok)

usb.agent[4145]: libmpio: loaded successfully

d) Then I type "open" in the mpiosh commandline and get
this error:

I think this problem may be related with some
libraries, byt I'm not sure, so I followed step #5 on
FAQ http://mpio.sourceforge.net/faq.html and I got this
debug logfile:

where is mkmpiodev?

2004-05-24T15:28:38Z

I ran configure
make and
make install as root.

Following the README file included in the TAR, I try to
run the /usr/local/sbin/mkmpiodev program but I discover
it is nowhere to be seen. When is this program built or
where is the script?

Thanks in advance
