I am working on a project that links to a 3rd party static library (herin refered to as EXTERNALLIB). In Visual Studio 2005 I was able to link to EXTERNALLIB and create a usable executable. Now we are using Visual Studio 2008 and I am receiving the following error: fatal error C1047: The object or library file EXTERNALLIB was created ...
I'm looking for implementations of set reconciliation algorithm. The problem is following: there are two sets with elements identified by some relatively compact value (e.g. UUID or MD5/SHA1/whatever hash) sitting on different machines. These sets differ in relatively few elements and I want to synchronize these sets while transferring m...
Where can I go to get information about the size of, say, unsigned int compiling under gcc for Mac OS X (both 32 and 64 bits)? In general I'd love to have a resource I can go to with a compiler/settings/platform/type and be able to look up how big that type will be. Does anyone know of such a thing? Update: Thanks for all the responses....
I have read a few lines of text into an array of C-strings. The lines have an arbitrary number of tab or space-delimited columns, and I am trying to figure out how to remove all the extra whitespace between them. The end goal is to use strtok to break up the columns. This is a good example of the columns: Cartwright Wendy 93 Willi...
Hi I wish to know which one is responsible for cleanup of the stack suppose you have a function fun lets say like this :- var = fun(int x, int y, float z, char x); when fun will get called it will go into the stack along with the parameters then when the function returns who is responsible for cleanup of the stack is it the function...
I wanted to know whether a 3D model library exists which is built upon opengl which i can use in my c/c++ code. for eg ,is there a library where there are ready models of viz.apple,fan,football which i can directly draw using c/c++? ...
Hi, I was just wondering why and how is __attribute__ used in C programs. thanks, ...
Hi, When I run my multi-threaded code, the system (linux) sometimes moves the threads from one processor to another. As I have as many threads as I have processors, it invalidates caches for no good reasons and it confuses my tracing activities. Do you know how to bind threads to processors, and why does a system would do this ? ...
connection to mysql is getting lost after 8 hours ( i.e afer wait_timeout varibale times out). i am trying to use mysql_ping() to reconnect to the server but ping gives me Mysql server gone away error. I am using sql version 5.1. so i am not using mysql_options() to enable the reconnect flag as mysql_real_connect() sets it to 0. I am exp...
Hi, Basic question, not clear to me for the regcomp man. If I have a static instance of regex_t, can I reuse it for several compilation without freeing it every time, something like: int match(char* pattern, char* name) { static regex_t re; regcomp(&re,pattern,REG_EXTENDED|REG_NOSUB); ... } The code itsel...
I've just come across the Ubuntu c-repl package which provides a REPL interface for C programming. Great! It is quite excellent for trying snippets and ideas, and intuitive to use. I love it. But there is no documentation at all, and I'd like to find out more about how to drive it. Example: > int foo( double x ) { return x+0.5;} > foo(...
Hi, there is this morphological analyzer (open source, written in OCml) named ocamorph. download and make instructions here The java binding is buggy and I'll have to fix it and after a few hours of struggle now it seems to me it'll take a few days to fix it as I'm not familiar with C, JNI, OCml and this particular software. Here you c...
I am trying to share some data across DLLs in a project which has an extremely complicated dependency structure (numberous DLLs). I want to be able to associate a key with some data in one part of the application, and then extract that data by supplying the appropriate key in some other part of the app. In a way, one can say that I loo...
I have several Gb of sample data captured 'in-the-field' at 48ksps using an NI Data Acquisition module. I would like to create a WAV file from this data. I have done this previously using MATLAB to load the data, normalise it to the 16bit PCM range, and then write it out as a WAV file. However MATLAB baulks at the file size as it does ...
I found this piece of code on the site, it seems the author is long gone, anyway, I'm having hard time understanding the actual swap and how the reverse occurs: void strrev2(char *str) { if( str == NULL ) return; char *end_ptr = &str[strlen(str) - 1]; char temp; while( end_ptr > str ) ...
I was wondering why the following code doesn't compile: void foo_int(int *a) { } void foo_long(long *a) { } int main() { int i; long l; foo_long(&i); foo_int(&l); } I am using GCC, and neither calls work either in C or C++. Since it is a 32-bit system, both int and long are signed 32-bit integers (which can be verifi...
what is decaying of array? is there any relation to the array pointers? ...
I'm trying to build a program I've written in C using GNU autotools, but I evidently have it set up wrong because when configure runs, it spits out: configure: error: C compiler cannot create executables If I look in config.log, I see: configure:2846: checking for C compiler default output file name configure:2868: gcc conftest.c ...
I am looking for an algorithm to prune short line segments from the output of an edge detector. As can be seen in the image (and link) below, there are several small edges detected that aren't "long" lines. Ideally I'd like just the 4 sides of the quadrangle to show up after processing, but if there are a couple of stray lines, it won'...
I'm on a network where I don't have root access, so everything I install is under a prefix ~/bin (actually referenced by its full path). So I have openbox working fine, which is what I'm using to send this from. Imlib2 I do ./configure --prefix=~/bin; make; make install. Then I run from the tint2 source directory IMLIB2_CFLAGS=-i~/bin/i...
