I'm having a bit of an issue using overloaded operators in an already overloaded operator. In my following code, I have overloaded the && operator to compare two Course objects. The operator in turn goes to a function which calls other overloaded operators to compare private object variables of that object to compare them.

I have been spending several days getting wxwidgets to work in code::blocks ide on several different platforms. Now I am down to one instance that I can't figure out. I have wxwidgets working in Fedora 13 x64, but cannot get it to work in a Fedora 13 x32 version. Actually, wxwidgets seem to be installed OK, but I run into compiler errors when I try to compile the default wxhello project. I get quite a few messages, in different header files, of this type:
/usr/include/assert.h:39:42: error: missing binary operator before token "("#if defined __cplusplus && __GNUC_PREREQ (2,95) From my friend Google this would seem to be caused by an older version of boost (before 1.37) - see http://bugs.xmms2.xmms.se/view.php?id=2215 ("It is an issue with old versions of boost and gcc4.4 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36453 It is fixed in boost 1.37")
I did a yum info command on both systems for every relevant package I could think of, including gcc(v4.4.4), gcc-c++(4.4.4), libgcc(4.4.4), libstdc++(4.4.4), boost(1.41.0), wxGTK(2.8.11), wxBase(2.8.11). Both systems are fully updated and have the same versions, with the only difference being 32 vs 64 bit. The same headers compile with no errors on the x64 system, but not x32. I have been able to find no other reason for this error than older versions of the preprocessor, yet that is apparently not the case here).

I just installed OS 11.4 this morning. Was previously on CentOS. I chose to have it import the partition & raid setup during install. Now when it boots it hangs with
"Could not find /dev/disk/by-label //" "Want me to fall back to /dev/disk/by_id/ata-ST(lots of drive stuff) -part2 (Y/n)" If I just hit ENTER at that point the boot will go on and it runs fine, but it stalls every time with that same error on boot. I did quite a bit of searching with Google and here (the search here considers every word in the error message to be too short or too common).
I have perl/tk installed and working. I tried using c++/tk and had to change the #include path in the headers to find the tk.h and tcl.h. I tried compiling a simple c++ program with g++ to test that the headers are correct. the line i type at console is:
g++ test.c cpptk.cc cpptkbase.cc -o test.bin
I fixed all previous errors, except for the following.

I don't know if this is the best place to ask this question. This question arose when I had a g++ compilation error: error: expected constructor, destructor, or type conversion before '.' token The above message can be correctly displayed in urxvt or xterm. But in mrxvt the '.' part can't be displayed correctly. Then I noticed that the quote signs are actually different from the usual ones and there seems no way to type ' ' from the keyboard. What are the differences and how to make mrxvt to display ' ' correctly. I found mrxvt very good and easy to configure.

On Slackware64 13.1 the as-installed en_GB locale gave Sunday as the first day of the week. This was not an issue until Xfce's Orage calendar was used when its display of Sunday as the first day of the week was offputting for someone used to Monday. A minor inconvenience but expected to be easy to fix.
At the command line:

I am trying to use the Linux Ramdisk y machine and followed the instructions oninux/Ramdisk/ramdisk.html to create a 4GB ramdisk (total memory is 8GB, linux 2.6.9)The issue is that it is taking me almost exactly the same time to read a 1GB file from ramdisk as it is from disk. I was expecting it to be atleast twice as fast.Has anyone encountered this before?
View 1 Replies View RelatedY want to rename a bunch of files and directories to remove the space on the names, easy enough right?
Code:
for source in $(find ./); do target=$(echo "$source"|sed -e 's/ /_/g'); mv -f "$source" $target; done
Well, I thought that should have work but the problem is that $source comes up broken, when I run it with echo instead of mv I get the echo with broken names.
Code:
In this case "$source"="This is the file I want to rename"
$ echo "$source"

I have an Acer Aspire 6930g with an nVidia GeForce 9300m GS which has a broken screen. I have been using an external monitor for some time using Linux Mint, without issue.
I initially set this up with great difficulty using the small parts of the screen that would still display an image at the time. Now, however the screen is totally dead, I have since disconnected the laptop monitor in order to not cause issues.
The issue I am currently having is trying to use live distros.
I'll give you example: I boot ubuntu 9.10 32bit and it gets to the initial boot menu. I choose "Try Ubuntu..." It shows the loading screen. Screen goes blank when going to desktop
I tried Ctrl+Alt+F1 to get to a terminal, but the screen stays blank. The same thing happens with both Knoppix and Backtrack 4 as well. The display goes blank upon switching to the desktop.

I have a binary value which I receive from a controller. Say this binary value is 42. Just plain hex 42. If you would look at that byte in a debugger you would see 42.Now this value hold 8 bits each indicating a high or a low output. So 0x42 = 01000010b. Which means bits 1 and 6 are '1'.When I would want to find out which bits are set and which are not in a language like C, I simply do:
Code:
mask = 0x80;
if (binval & mask) {...}
etc..
However I am programming in TCL, and I try to do:
Code:
set mask 0x80
if { [expr ($binval & $mask) > 0] } {...}
etc...
this fails. At the moment the expr is executed, $binval is evaluated and substituted so the expression I am evaluating is
Code:
set mask 0x80
if { [expr ('B' & '0x80') > 0] } {...}
etc...
Eventually I got it working by converting the $binval into a '0x42' string value, like this:
Code:
binary scan $binval c byte
set byte [format "0x%0x" $byte]
set mask 0x80
if { [expr ($byte & $mask) > 0] } {...}
etc...[
Then the expression yields what I want. But this seems so stupid and clumsy. Isn't there a better way where I can compare two binary values without conversions?

I'm very new at Bash scripting and have a bone head issue that I'm trying (and failing) to resolve. I cannot get this one IF statement to work, it seems the comparison operator does not think the resulting number from the $b*$c+$b operation is an integer even though it is a number. Below is a small proof of concept script with the bit I'm having trouble with.

#! /bin/bash
a=800
b=700
c=.15
if [ "$a" -le "$(echo "($b*$c+$b)"|bc)" ]
