cc

Any reason cc -g -lm -DBLITZ_HOST_IS_LITTLE_ENDIAN would produce an error with code using math.h ? Is it possible there's a difference between GCC version 4.0.3 (documented working version) and version 4.6.3 (my current version)? makefile and asm.c @ https://gist.github.com/3801291 This is on ubuntu 12.04 My terminal output is a comment in the gist. Instead of cc -g -lm -DBLITZ_HOST_IS_LITTLE_ENDIAN foo.c Try: cc -g -DBLITZ_HOST_IS_LITTLE_ENDIAN foo.c -lm When the linker searches a library, it links in modules that contain definitions for previously-undefined symbols. If the linker searches

#include <stdio.h> #include <stdlib.h> struct NODE { char* name; int val; struct NODE* next; }; typedef struct NODE Node; Node *head, *tail; head = (Node*) malloc( sizeof( Node ) ); //line 21 And I compiling like this: cc -g -c -o file.tab.o file.tab.c I'm getting this error message: file.y:21:1 warning: data definition has no type or storage class [enabled by default] Natan Streppel It looks like the line head = (Node*) malloc( sizeof( Node ) ); //line 21 is outside the main() function. You can't do that, because you can't execute code outside functions. The only thing you can do at global

I have the following part of C code: char c; int n = 0; while ( (c = getchar()) != EOF ){ if (c == "\n"){ n++; } } during compilation, compiler tells me warning: comparison between pointer and integer [enabled by default] The thing is that if to substitute "\n" with '\n' there are no warnings at all. Can anyone explain me the reason? Another strange thing is that I am not using pointers at all. I am aware of the following questions warning: comparison between pointer and integer [enabled by default] in c warning: comparison between pointer and integer in C but in my opinion they are unrelated

If cc configuration is set to use -Werror is there a way to override -Werror flag from the terminal when using make? You can set flags when invoking make: CFLAGS=-Wno-error make 来源： https://stackoverflow.com/questions/11750988/quick-way-to-override-werror-flag

Please help :) OS : Linux Where in " sleep(1000);", at this time "top (display Linux tasks)" wrote me 7.7 %MEM use. valgrind : not found memory leak. I understand, wrote correctly and all malloc result is NULL. But Why in this time "sleep" my program NOT decreased memory ? What missing ?

背景 2013年是网页设计响应式的一年。所谓响应式网页设计，是由Ethan Marcotte在2010年提出的名词，指可以自动识别屏幕宽度、并做出相应调整的网页设计。简单来说就是同一张网页自动适应不同大小的屏幕，根据屏幕宽度，自动调整布局。这是一个多么强大的概念，一套代码兼容所有设备，节省维护成本，提高开发效率。然而，现实并非如此完美，在其强大的背后也有鲜为人知的辛酸苦楚。 众所周知，在响应式设计出现或者说在各种移动设备不断迅速抢占PC市场之前，所有的网页设计几乎不要求兼容移动设备，而在PC端的开发调试已经相当成熟，各种调试工具纷纷脱颖而出，诸如：Firebug、Chrome开发者工具等。这让开发者如鱼得水，在传统网页设计中游刃有余。 而如今的互联网市场已经有很大一部分属于移动设备的领地，网页设计兼容移动设备刻不容缓，而响应式设计的提出让这一目标成为可能，甚至可以说是网页设计兼容移动设备的完美解决方案。但是，光有方案只能是空谈，几乎没有人能够不经过反复调试就能写出完全正确的代码，移动设备上的开发调试给网页设计带来了阻力，让开发者不得不投入更多的成本用以对移动设备兼容的调试。所以良好的移动开发调试工具必须问世，而拥有一款优秀的移动开发调试工具，必然给响应式网页设计锦上添花。 人类的智慧是无穷的，2010年底weinre问世，至今weinre已经发布2.0.0版本
