Programming :: Get Eclipse C Compiler To Work - Warning: Implicit Declaration Of Function Strlen

Feb 11, 2009

I have the plugin installed ok and have pasted in a C source file that I know works and am getting the following errors, I think because the linker options need to be set in some way. I cannot copy the errors but they all complain of implicit declaration of functions like this: -

warning: implicit declaration of function strlen

But I have the headers included, is this a linker problem? Here is the code -

#include <stdio.h>

General :: Difference In C Programming In Gedit & Turbo C?

Sep 6, 2010

In our college all the systems (running on windows xp) have TURBO C/C++ installed on them which we use for C programming. I recently installed ubuntu 10.04 on me laptop (DELL Inspiron 14R (N4010) with some modifications) i read somewhere on the internet that Gedit can be used for writing a programme in ubuntu which can be compiled using gcc. Well if i use Gedit rather than Turbo c will i experience any differnce?, i mean is there any problem in doing so?? Or i should prefer running turbo c using DOS BOX?

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?

May 18, 2010

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

Programming :: Fexec-charset For Preprocessor Or For C Compiler?

Dec 24, 2010

I'm reading about GNU CPP(GNU C preprocessor). In the CPP manual -> 1.1 Character sets:

Code:
After preprocessing is complete, string and character constants are converted again, into the execution character set. This character set is under control of the user; the default is UTF-8, matching the source character set. I think "under control of the user" means to use the option -fexec-charset=, right? And in the above part, it says pretty clear: "After preprocessing is complete", so the job -- "string and character constants are converted again, into the execution character set" -- should be done by the C compiler(compilation proper), not GNU CPP. Then the option -fexec-charset= should be an option controlling the C compiler, not the preprocessor. But in the GCC manual, this option is listed in the "3.11 Options Controlling the Preprocessor". I don't understand this, If this option is an option controlling the preprocessor, it conflicts with the CPP manual. How to understand this?

Programming :: How To Force Scons To Use Cross Compiler

Feb 3, 2010

I have a large existing codebase that all compiles under Ubuntu 8.04 with g++ using Scons. I've been given the task of getting it to compile for Arm9 running uclinux. I have a arm-elf-g++ compiler that I need to use instead of the gcc version. I ended up borking my /usr/lib/scons/SCons/Tool/g++.py file to use arm-elf-g++ instead of g++, but I know that this is not correct, as I have to go edit that file every time I change compilers.

These are the 2 lines I switch out:
Code:
compilers = ['arm-elf-g++']
#compilers = ['g++']

I simply can not find anywhere in the scons documentation that indicates how to tell it to use a different compiler. It seems that it would go under "Environment" but beyond that I'm lost. The CPPPATH variable seems like it only tells scons where to find #include files. I suppose I could rename arm-elf-g++ to g++ and just set my path to find that one first, but that seems like a bit of a hack as well. It would also break other things on my machine.

Programming :: Pthread Mapping From Compiler To Kernel?

Aug 20, 2010

I'm trying to figure out how pthreads are mapped from the compiler to the Linux kernel. The pthread prototypes are found in a compiler header file (pthread.h), yet the kernel would be responsible for scheduling the threads. So, how does the compiler resolve the pthread symbols at compile time?

Programming :: Surface Fitting Using NR Function Svdfit ( ) In C Programming?

Sep 16, 2010

fit a surface i.e. W(x,y) using svdfit() provided by "Numerical Recipes in C". svdfit() is written for curve fitting and not for surface fitting.But one can use svdfit(), as claimed by authors of NR book, to do surface fitting. On page 680 of NR book, authors have given a hint on how to use svdfit() for fitting a surface. But I have not understood it.This link may be helpful (Chapter 15 th is relevant here.):[URL]This is my problem:

Programming :: Disable Structure Alignment Using Gcc Compiler Options?

Jan 25, 2010

How can I disable structure alignment feature of gcc using command-line options ?I recently migrated to 64-bit OS, and doubt that I might be experiencing a structure alignment problem due to the new 64-bit architecture.I checked the sizes of the same C-style struct in both x86 and x86_64, and found out that they appear to be different by 20 bytes.I am not sure if this is due to structure alignment or the differences in data type lengths between two platforms.Hence, I will first disable the structure alignment feature, and then check the struct sizes again.

Software :: Build A C Compiler Without An Existing C Compiler?

Dec 14, 2010

So for those of you who has built GCC from source would know that you can't install GCC without an existing GCC. So my question is, what would happen if all computers in the world suddenly just died, and all you had was the computer in front of you, and a copy of GCC 4.5. How would you install that?

I ask because I would like to install GCC 4.5 on my old powerbook G4 mac without installing a binary GCC provided by Tiger 10.4 disks. I would like to build GCC from source, without an existing GCC to complicate updating.

Programming :: Finding G++ Compiler Option To Avoid Forward Declarations

Sep 23, 2010

I am working for a product which was evolved over a decade. There I have some combination of C style coding and C++ coding in same libraries. I am landing on some instances where C style function is expecting forward declarations for some other function for which I can not declare (due to design and architecture). Is there any g++ compiler option that directs the g++ to look whole preprocessed file (because definition is there down in the preprocessed file) than only forward in the preprocessed file. All these years this code is working as we are using CC compiler and that looks entire preprocessed file than only in the forward direction.

<Sample Code
Header1.h file
Function1()
{

[code]....

if I can not include Header2.h first then Header1.h. I have to include Header1.h and Header2.h because on the design hierarchy in this product. Also the function definitions are in header files as they are either template functions or functions expanded through macros.

Programming :: Add Some Compiler Flags In Code Blocks / IDE For Mysql Headers And APIs?
