<0> like it?
<1> Prague is a beautiful town.
<2> Yup
<3> another question
<1> (It also has the oldest German university. But you can't really say that (at least if you're German))
<2> Been here for 3 weeks (with some week off in the middle)
<2> Some morons crashed some cluster
<2> For a restore test
<3> I include a couple of C-headers into my C++ code
<2> And they didn't unmount /inbackup before doing rm -rf /
<2> So they deleted the backups as well
<4> doh
<1> Let me guess, the crashing was quite successful.
<3> why is that I need to compile those C-files before I can compile and link my C++ program?
<2> And they didn't backup on tape cause "I don't know how to tar files > 8 GB"
<2> So I didn't know either
<2> I typed man tar
<2> I showed -E
<5> corstan you don't
<2> And I slapped them
<5> you need them before you can LINK
<5> but not compile
<3> vawjrwrk, need what?
<2> Well, I restored it without the Oracle archive logs, in 1 day :D
<2> For a cluster of 8 machines
<3> vawjrwrk, the C-files?
<1> Ashe`: that's silly. They should give their pay cheque back.
<5> corstan of course
<3> vawjrwrk, I have them in the same dir.
<5> so? what's your point?
<4> corstan you need to compile everything you want to link, before you can link...
<2> I shouldn't have restored it, they'd get fired
<2> Those people are completely dumb
<2> I gave one a file to put on one of the machine (a new .so)
<2> Told him to just restart that process
<2> And he shuts down the whole cluster
<3> vawjrwrk, but I always end up getting errors about functions I have in the C-files cannot be found when the C++ code is being compiled
<2> And reboots everything
<2> :/
<3> vawjrwrk, so after I have #include
<1> That *does* restart the process.
<2> Yeah, I guess, but it prevents people from giving phone calls for 15 minutes
<3> vawjrwrk, I do: gcc -c *.c -lm e.g.
<3> vawjrwrk, then I: g++ -o foo.app *.cpp *.o -lm ?
<4> corstan you're not making much sense
<4> as usual
<5> corstan learn about make
<3> I am using shell script
<5> learn about make
<3> first I need learn about compiling correctly
<5> but that looks about right
<6> make is good. I just learned it a month ago... so sweet
<2> About time heh
<2> It's probably the only thing that's almost as old as vawjr
<6> well, I just started working almost primarially in linux a month ago, so I hadn't needed it until then
<3> vawjrwrk, so I am obligated to have object files of the C code before I can compile the C++ code, even though I have #include of C code in the C++ code?
<5> jsaacmk what were you working in before?
<3> making any sense?
<6> just windows using like VC++\
<1> jsaacmk: a fun thing is that you can use make for a lot of other work, too.
<4> corstan - not at all
<2> Like washing the dishes
<1> make dishwash
<2> Usually I put that in clean:
<7> Hi Debugger, short time since I last used you.
<8> i am having trouble linking a .lib file using MinGW g++
<8> doesn't seem to work
<2> Maybe it was made with VC++
<4> Bob77 - care to tell us what 'doesnt seem to work' might mean?
<8> lol
<3> rdragon, you totally understand what I meant?
<9> Icewolf: haha :)
<7> Oh I wish the debugger was in person :)
<4> corstan - I understand what you wrote, which is quite possibly not even close to what you meant
<3> heh, oh god
<8> yeah, the .lib was made using VS
<8> i thought they were standardized
<4> "<3> vawjrwrk, so I am obligated to have object files of the C code before I can compile the C++ code" <-- I can't imagine that this is true
<3> he's not gonna help --> http://maps.google.com/maps?ll=-16.341133,-71.965269&spn=0.155239,0.240704&t=k&hl=en
<1> clean:: dishwash
<5> Bob77 nope
<1> clean:: vaccum
<3> rdragon, step by step then
<5> corstan what rdragon quoted is NOT true
<8> fork
<3> rdragon, I compile the C files: gcc -c *.c -lm <-- fine ?
<2> Nope
<5> you need the header files so you can compile everything
<2> You have a -l
<4> is that jesus in the sand?
<5> you need the object files to link
<3> vawjrwrk, I need the header files?, of course they are in there
<3> !!!
<3> they are included in the C files
<3> now I am talking about C code only
<5> also the cpp file(s) one trusts
<4> corstan nobody has said anything about header files
<4> oh, i guess vawjr did, heh
<2> Compile .c to .o
<2> Declare in .cpp as extern "C"
<3> ok, I skip the -lm
<2> Compile .cpp to .obj
<2> Link them all
<5> he was complaining earlier that he was getting "undefined" while compileing the c++ stuff
<2> And in the darkness, bind them
<3> gcc -c *.c
<2> Ehm, that was the linking I guess
<3> --> *.o files great
<2> So do the same with the .cpp
<5> how smart IS make these days
<5> with it's defaults
<1> I rarely use them.
<5> does it try to link all the .obj and .o files if you do make widget
<5> and there's a widget.cpp plus a few other odds and ends
<5> and NO makefile
<6> all I know is that make will only do the first thing, and make whatever depends on it
<5> actually whatever it depends on
<6> oh yeah... oops
<10> humm
<11> hi world!
<10> all the sin cos operations are in radians right?
<12> tux1, they are not in degrees
<13> Mainly, corstan is confused about the distinction between compiling and linking
<3> poor corstan
<10> why processors preffer to do calculations in radians that in degrees?
<12> vim has some fun make integration
<5> because it's math
<5> sin(x) is defined in math and it has nothign to do with degrees
<5> and the processor doesn't do it (most likely a library does)
<10> ho because degrees is just a way to me***ure angles???
<3> radian are pretty standard in numerical calculations
<3> Matlab uses it as default
<3> radans
<3> err, radians
<4> it's pretty trivial to convert degrees <--> radians, with a little pie
<1> tux1: did you ever look at the Taylor series for sin()/cos()?
<12> well, if you want to calculate trigonometric functions, the algorithms like taylor series or other less precision ones work for radians by default
<10> no never
<5> how much math have you studied?
<1> You could write the Taylor series for sin based on degrees, of course. But it would look ugly.
<12> yeah
<8> anyone compile opengl applications under MinGW32 ?
<12> Bob77, sure. Why?
<8> know where i can get the libraries for opengl under mingw32 ?
<12> there are several ways, I used a devpak plugin from code::blocks to get it.
<12> doesn't mingw come with it anyway?
<8> it comes with .h but not with .a
<14> hi
<14> can anyone help
<1> You can help yourself by reading the channel topic first.
