In general, one “registers” a new mount filesystem type by creating an executable mount.fstype. $ ln -s /usr/bin/vdbfs.py /usr/sbin/mount.vdbfs If vdbfs.py takes mount-ish arguments (i.e. dev path [-o opts]), then mount -t vdbfs and using vdbfs as the 3rd field in fstab will work. If it doesn’t, you can create a wrapper which does take … Read more
No, the order is not defined. That is the whole point in using declarative dependency-oriented programming: that the computer can pick the optimal evaluation order, or in fact, evaluate them even at the same time.
Although Hasturkun’s solution will work, I think the idiomatic way to write this is: ifeq ($(TEST_FLAG),TRUE) ifeq ($(DEBUG_FLAG),FALSE) # Stuff endif endif
See show-paren-mode as described in 5.27 How do I show which parenthesis matches the one I’m looking at?
Have you tried simply running your executable in gdb, and then just hitting ^C (Ctrl+C) when you want to interrupt it? That should drop you to gdb’s prompt, where you can simply run the where command to see where you are, and then carry on execution with continue. If you find yourself in a irrelevant … Read more

Functions of this kind can be subject to data flow analysis and might be eliminated. __attribute__((const)) function attribute … Read more
You can make use of: #ifdef __GNUC__ #ifdef __MINGW32__ For additional macros you might be interested in this page which shows other compiler macros.
See the GNU Screen chdir command. All new windows created in Screen use this as their initial directory. Using this, you can do something like: chdir /home/dan/newscreendir screen And your new window (along with any future created windows) will be in the set directory. If it’s always going to be the current working directory you … Read more
The variable MAKECMDGOALS contains the list of targets that were specified on the command line, no matter how many (it’s empty if there were none).
As I was about to complete writing this question, I ran parallel –version to report the version, only to find: WARNING: YOU ARE USING –tollef. IF THINGS ARE ACTING WEIRD USE –gnu. It is not clear to me why that flag is set by default. Needless to say, using –gnu worked! Thought I would post … Read more
