<0> Object-Oriented Programming in C++
<1> I haven't yet read that
<1> I haven't cared much for the Sams publications on C++
<2> what do you understand from 'Ogre::Scenemanager *ExampleAplication::mSceneMgr'?
<3> hi
<3> why when i try to write a string to a file like this :output_file<<s; all the spaces get cancelled
<2> anyone using vc++?
<3> yes
<2> what does Ogre::Scenemanager *ExampleAplication::mSceneMgr mean?
<3> yes i'm using vc++ 2005, but how can i get it to work?
<4> which spaces get cancelled?
<4> being taken out of context it means nothing newtoogre
<3> oh sorry
<2> melfar: when i go over mSceneMgr, vc++ shows 'Ogre::Scenemanager *ExampleAplication::mSceneMgr' as a hint
<3> my mistake
<2> melfar: do you have an idea about it?
<4> looks like a static var of Ogre::blablah* type
<4> maybe not static, depends on how vc shows it
<5> I have a question....
<5> if I have a vector cl*** with a type def Point
<5> and I have a matrix cl*** that multiply a vector * a matrix and return that vector.
<5> If I multiply a Point times the matrix will that work?
<6> i am trying to link c and c++ files (don't ask why). And i have a function defined as extern in a .c file and i want it to be linked to define it in c++ file. What do i say in c++ file to be able to link properly ?
<4> extern "C" { prototype(); } in c++ file?
<6> can i just do extern "C" int func(int) { ... } ?
<6> ie, do i need the set of brackets after "C" ?
<4> what does the experiment say you?
<6> doesn't work
<6> says symbol undefined
<6> and if i do extern "C" it gives me a conflict
<4> which conflict?
<6> says previous declaration of ..func... with C++ linkage conflicts with new declaration with C linkage
<6> g++ is a C++ compiler right ?
<4> you get this conflict when you extern "C++" in one place (which is default for c++) and extern "C" in another (which is default for c)
<5> ok I have a cl*** Vector (bla bla); typedef Vector Point
<5> when I make a Point on the main
<5> it does not let me use its functions
<5> why??
<7> how can i run the "ls" linux command through c++
<8> why would you want to?
<8> if you want to work with directories and files, check out boost.filesystem
<5> rdragon
<5> why when I do the typedef Vector Point
<5> when I declare a point it does not letme access the functions of it that are defined in Vector
<7> i handle some events related to the creation of folders and i want to list the files within this dirctory
<8> typedef Vector Point; why is that useful? Just use Vector
<8> and it should, anyway, since it's just an alias for the type
<5> because I need a point in but I dont want to make a point cl***
<5> so I am using typedef Vector Point;
<8> typedef Vector Point; makes Vector and Point interchangable names for Vector
<8> so you're just obscuring what's going on by giving 2 names to the exact same thing
<5> I know but then when I put in my main Point something; something.memberfunction;
<5> it gives me and error
<8> like what?
<5> d:\ribTokenizer\main.cpp(11): error C2228: left of '.set4To1' must have cl***/struct/union type
<8> maybe that code doesn't see the typedef, then
<8> just use Vector
<5> I cant I need to use points.
<8> it's the same ****ing thing!
<8> a typedef doesn't create a new type
<5> no for what I am doing
<8> it's the SAME THING
<8> void f( Vector v ); Point p; f( p ); //completely fine, Point is Vector
<5> ok can you jsut tell me why the typedef point would not work...?"
<8> it does work, your code just likely doesn't see it, or doesn't see the definition of Vector
<9> pharon: std::system("/bin/ls")
<9> calc dir
<10> dir = Under Windows, use the FindFile Win32 API calls (see <http://msdn.microsoft.com/library/en-us/fileio/filesio_4qcl.asp>; for more information), or call system("dir c:\\path\\to\\folder /b > file") and process the resulting file. If you're on a Unix-like OS, use opendir/readdir/closedir, or call system("ls /path/to/folder > /tmp/file") and process /tmp/file.
<5> I am putting the typedef Vector Point only in the Vector.h
<5> shoul I also put it in the .cpp and in the main?
<8> no, you should #include "Vector.h"
<8> and you should remove the typedef completely
<7> thanks _m_
<5> so where should I put the typedef Vector Point?
<8> you should get rid of it
<5> but if I want to use it where should I put it?
<8> in Vector.h, but you shouldn't use it
<11> anyone know the channel key for #amd ?
<12> try "intel"
<4> Cantide: /names #amd , them pm ops
<4> then even
<11> ooh
<11> ok, thnx
<11> i didnt know you could /names
<11> i tried /list #amd... but there isnt a topic :S
<6> how do i tell a compiler not to mangle the name of the function in a .cpp file so it can link with a .c object ?
<8> you want to call a C++ function from C ?
<6> yeah
<8> provide the function declaration with extern "C"
<1> omelche who is callin whom in your scenario?
<6> the c library is trying to link to a c++ file
<6> c library depends on one of the functions to link
<1> ok, you might have some problems with that depending on whether the name of the function is unique or not
<13> Anyone familiar with RAS?
<13> When I try to RasDial() and entry I previously create, it actually adds "9,1-418" before the number so the connection will not work. How can i prevent the conection from using area and country code?
<1> this has something to do with C++ ?
<13> totally
<1> I don't see how...and saying "I'm writing my program in C++" won't cut it
<13> if you didnt understand, add "in c++" at the end of my sentence
<1> I guess you simply don't understand....go look up RasDial and see what all the arguments are
<13> I did, its not in there
<1> bull****
<9> It's not in here, either.
<13> wel...
<1> the 1st arg
<1> but the problem looks like someone ****ed w/ your RAS Phone book
<13> well the 1st parameter is ignored
<14> I don't have RasDial here
<1> you wuold if you used a _real_ OS
<1> lol
<13> and yes, i do need to modify the phone book (actually the registry since its CE) so it doesnt take th earea and country code
<1> well, this all sounds like an OS problem, not C++
<13> well sorry for not being cool enuff and not using a _real_ OS
<6> vawjrwrk : when the function is implemented in .c file and compiled with a c compiler, linking goes ok, if i try to compile it with a c++ compiler then i get a link error, any idea on how to avoid it ?
<1> I was talking to jottinger
<13> k
<1> thought CE is the only accurately named OS that Microsoft has ever shipped
<8> the goal is not to 'avoid' or 'hide' the error, it's to fix the problem causing the error
<1> WinCE a perfectly good English word which describes every programmer's initial reaction to it
<8> it's nonsensical how many people say "how do I get rid of the error message"
<14> vawjrwrk++
<13> so anyone REALLY familiar with RAS?
<1> RoG go away NOW
<6> let me rephrase the question
<14> vawjrwrk: and screw you, I have a bunch of real OSes, and only one of which would happen to have anything to do with RAS
<1> go fix you damned phonebook
<6> is there a way to call a c++ function from c ?
<14> omelche: yes
<6> if the function is defined as just extern void func(void)
<1> omelche if it's a C program why are you compiling it with a C++ compiler? but as you were told earlier define it with extern "C"
<1> that's not how you _define_ things
<13> or anyone has any link on how to modify call options and baudrate on a RAS client connection
<1> you _define_ things where the code is, not where you're trying to use it
<13> IN C++
<6> g++ -o hw1 -g -I/cad2/ece540s/ece540/suif/include doproc.o bitvector.o labeltab.o main.o print.o BB.o \

<6> Undefined first referenced
<6> symbol in file
<6> do_procedure /cad2/ece540s/ece540/suif/SPARC/lib/libsimple.a(simple.o)
<1> goodby RoG
<6> this is the error i am getting
<6> sorry for pasting in chan
<6> i will use the website next time
<1> you're including source files?
<6> those are c libraries
<1> not with an extension of .cc
<1> that's a SOURCE file
<6> oh that
<1> oh, sorry, that's your source
<6> no
<6> its not
