<0> Hello! I am having trouble with a make. I know that certian header files are present, but make cannot find them. Any clues? (btw, I am rather a novice.)
<1> can someone point me to a good site for creating a custom ***embler that produces elf object code?
<2> im trying to do some inline arm asm with gcc and failing miserably
<3> what mtune should i use for pentium d? mtune=pentium4 ?
<4> Hello, does anybody know why printf("%d\n",sizeof(malloc(10000))); prints 8 on gcc 4.0.3 (Ubuntu 4.0.3-1ubuntu5)?
<5> because it return's an pointer to the allocated memory
<6> flosch, should'nt it be 4 then
<5> maybe it's an x86-64 system?
<7> hello, is x<?y a gcc extension?
<8> no, it's standard c
<7> oh thanks
<7> is interface a g++ extension?
<8> interface?
<7> defining interface in c++
<8> I'm not sure what you mean
<8> like a pure virtual cl***?
<7> yes
<8> those are standard c++
<7> oh.... faint... i don't know that
<7> but i have difficulty in finding information about "interface" in c++
<8> try "abstract cl***es"
<8> or "pure virtual"
<7> err.. i just saw this "#define interface cl***" in some header file... what the...
<8> ... oh so that's what you meant
<8> there is not standard "interface" keyword
<8> and abusing the preprocessor in that way is certainly inept
<7> i see. thanks
<7> Zordan_, may i ask if you use IDE for programming c++
<8> sometimes
<8> not on linux though
<7> oh... i see. thanks
<9> hi
<9> i compile hello.cpp and i got this error
<9> /tmp/ccGEiOn7.o: In function `main':hello.cpp:(.text+0x27): undefined reference to `std::cout'
<9> :hello.cpp:(.text+0x2c): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)'
<9> /tmp/ccGEiOn7.o: In function `__tcf_0':hello.cpp:(.text+0x46): undefined reference to `std::ios_base::Init::~Init()'
<9> /tmp/ccGEiOn7.o: In function `__static_initialization_and_destruction_0(int, int)':hello.cpp:(.text+0x6f): undefined reference to `std::ios_base::Init::Init()'
<9> /tmp/ccGEiOn7.o:(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
<9> collect2: ld returned 1 exit status
<9> which i have no idea what's gone wrong
<8> looks like you probably linked with gcc instead of g++
<9> so i should just relink to g++?
<8> "with" not "to"
<9> ???
<9> my g++ is link to gcc-4.0
<9> nope, i meant g++ is linked to g++-4.0
<8> g++ is another frontend ... not a link
<8> just "g++ hello.cpp -o foobar"
<9> oh,
<9> jesus
<9> :(
<9> basic fundament mistake
<9> fundamental*
<9> thanks
<9> it's solved
<8> np
<9> you are very helpful Zordan_
<9> :)
<9> bye
<10> Hi! i have a newbie question, if i try to use undeclared struch, why the compiler gives strage error: 'error: storage size of 'sa' isn't known' instead something like 'struct 'sa' not declared', etc. ?
<10> .. and where is struct sockaddr declared??
<11> apastinen: because using a struct not yet declared is not error, but using it for things where you need a storage size is.
<10> nosha, hmm.. ok, maby i learn some day why it is not yet error.. =)
<11> apasinen: its some form of capsulation, only things needing it have to see the decleration, everything else can work with pointers to it...
<10> noshadow: ok, thanks.. i think i got it now.. =)
<12> Hi. Can someone tell me why gcc issues a warning about no newline at end of file? (I am not complaining at all, I just want to know about the reason behind it, if anyone knows.)
<8> the standard says that a source file has to end with a newline
<12> thanks
<13> If I have a C function that is fully inlined by the compiler (I checked) and thus never called, how do I stop it from also generating code for the function to allow it to be called ?
<11> shevegen: if it does not have a \n at the end, it is no text file. And funny things can happen with non-text-files with many other tools.
<14> Hi! With what function can i read exactly n byte from a file into a char*?
<11> zzz: that is no gcc question but a question about you C lib. typically one calls read(2) repeatedly.
<14> noshadow: oh, read is the function i need.... . thx.
<13> Ahh, found out. To have inlined C functions not be generated for calling, declare them static.
<15> Hrrg. Do any of you know intuitively how the GMP C++ interface works?
<15> Because I'm trying to write a similar one for GSL, but it's quite difficult.
<16> if i compile my unittests with -O0, i get all p***es. If i compile with -O1, I get an ***ertion failure. should i file a bug with gcc and attach code+
<16> it compiles clean with -Wall
<16> has someone written a tool which serially compiles a program with different specific optimization options to track down which one causes gcc to generate incorrect code?
<17> hello
<17> I have a problem
<17> `-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
<17> why?
<18> Can anyone tell me if there's some way to let the compiler know that an inline ASM block will modify a global variable? Declaring it volatile isn't doing it.
<18> Also, I'm trying to give it a clobber list but it's saying "can't find a register in ____ cl***", is that because the registers are not clobbered in the actual ASM block?
Return to
