Hi all! I have implemented a shared library in Linux and try to test it, but I get an error "undefined reference to `CEDD(char*)'". I use Eclipse with following parameters: Path to include files (here is everything ok) Path to the library and its name. Path is correct and the name is WISE_C (full name: libWISE_C.so) My Code: Test...
I would be interested to in knowing how you out there handle the bumping the version number for new releases issue. How do you handle the version number in associated files like man pages, etc. The software is build with the gnu tool chain so autoconf, automake, etc are available and used for the version number of the application. So t...
I'm a long time user of the .NET Framework on Windows platforms, but I do a lot of programming on Linux as well. I'd like to take advantage of Mono for some particular projects, but the last time I tried (maybe 2 years ago?), Mono was simply not up to the task. As well, it was particularly difficult to get really good information on the ...

I hope this is the right forum for this, and excuse the naive question. I would like to provide an "guest" login to a (non-dedicated) linux server and run just one console application. The user cannot do anything more than use this application. A scenario could be: ssh dervinATsomehost.com (no password) and the just automatical...
I am sending data from a linux application through serial port to an embedded device. In the current implementation a byte circular buffer is used in the firmware. (Nothing but an array with a read and write pointer) As the bytes come in, it is written to the circular bufffer. Now the PC application appears to be sending the data too f...
According to g++ -print-search-dirs my C++ compiler is searching for libraries in many directories, including ... /lib/../lib/: /usr/lib/../lib/: /lib/: /usr/lib/ Naively, /lib/../lib/ would appear to be the same directory as /lib/ lib's parent will have a child named lib, "that man's father's son is my father's son's son" and all ...

In VMS DCL one may embed data in a command file using $DECK and $EOD. What is Linux for this? ...
In VMS one may tell the file system to write junk over the existing contents of a file when it is deleted. Here is the DCL command to identify the file for this kind of treatment: $ SET FILE/ERASE_ON_DELETE SAMPLE.TXT This allows the policy to be set at one point in time then later users of the file do not have to handle that detail ...
VMS editor EDT allows one to use the keypad to control most of ones editing commands. One of the rather nice features is that the direction of operation can be set to "up" or "down". This then effects commands like "move to next character" and "move to start of line". Another feature is that there are "character", "word" and "line" buffe...

Would you consider that using just one of these tools is adequate? I'm not looking for recommendations (I can find plenty of those) b...

I have a script that is to be run by a person that logs in to the server with ssh. Is there a way to find out automatically what ip is the user connecting from. Of course, I could ask the user (it is a tool for programmers, so no problem with that), but it would be cooler if I just found out. ...
