Hi, I have creating a new ibr-dtn tool like dtnsend but It is difficult for me to understand where should I include it in Makefiles or configures, because I’m not used to work with complex makefiles or automakes. I already tried to included it in several places, but it’s not working. Can you help me to know where should I include my *.cpp files for ibrdtn-tools compilation? I already have the source code in my pc and I comment the wget and tar lines of bash script not to replace my new code. I have also a tool in a server to receive data from my other ibrdtn nodes and then I introduce my information in a mysql database directly when I receive a bundle. However, I have being also problems including the mysql -libs and -cflags. When I compile a simple c++ program to introduce information in mysql database I have to include at least -lmysqlclient (g++ -o program program.cpp -lmysqlclient). I also tried to include mysqlclient in several places, but it’s not working. Can you help me to know where to include it? Thanks a lot, Tiago

Hello, i try to enabled time-synchronization like you told me before. but i still got the same error (bundle received-queued-deleted-expired) i think i must enable the blob path, but when i enable it blob_path = /tmp/blob/ i still got the same error "could not create a temporary file" it is affected by the directory's ownership or permissions this ls -l /tmp/ outcome drwxr-xr-x 2 root root 4096 Jun 2 14.05 blob ? or there is another option to fix this error ? thank you :) Hello. > > Am 30.05.2014 15:37, schrieb Stephan Rottmann: > > another option is to enable the dtn timesync in the config, but > > johannes/the documentation knows better about this... > > To enable time-synchronization, you need to declare at least one node as > reference.

helo, > Does the path /tmp/blob/ exists? > If not create it. > > If yes, try to disable (comment-out) blob_path and tell me if the error > is still there. > i comment out the blob path and the error message disappear. but i got 'timeout' when i try to dtnping. and the notice seems repeating this : - new bundle queued - bundle deleted - bundle has been expired - bundle received it repeated again and again and dtnping still timeout. thank you :)
