New subject: [Serusers] ser crashes

6 Feb 2003

Thank you, the path to the modules was the problem!

Now ser runs also as self compiled version and doesnt crash. I didn't
had to change the source because the source code available to download
is already corrected. To proof your guess I inserted the error again (
len+=) and than it crashes again.

Conclusion: with the source code version from 0.8.10 ser doesn't crash
anymore. Nevertheless, /var/log/messages shows an error message when I
send my special invite:

Feb  6 15:48:24 obelix /usr/local/sbin/ser[6985]: ERROR:
t_build_and_send_CANCEL: cannot allocate memory

thanks and regards,
Klaus

 Double check path of the modules. Probably you are using 
 config file from the rpm package, after make install the 
 modules will be in /usr/local/lib/ser/modules. The rpm 
 package installs them in /usr/lib/ser/modules so you will 
 have to change it.

 There is no uninstall in the makefiles, you can uninstall 
 only by hand right now.

  Hello!

 I have problems running the self compiled ser version (without any 
 sourcecode changes).

 I uninstalled the rpms ("rpm -e ser-mysql" and "rpm -e ser" - I use 
 the mysql authentication). Then I compiled ser with "make   all" without

  errors. I installed ser with "make
install". Then I tried   to start ser
  with:
 # /usr/local/sbin/ser -f /etc/ser/ser.cfg
 ERROR: bad config file (25 errors)

 Why does my config file doesn't work anymore (it worked   with the rpm 
  version)? When I start ser with -f, than it
starts (but than it 
 doesn't use the mysql database).

 Have I done something wrong during the installation/compiling?

 How can I delete the files that were installed by "make   install"? make

  uninstall?

 klaus
