When compiling a C program i get the following errors.How do i modify the code to remove these warning messages?
1) "test.c", line 614: warning #4212-D: mismatch between character pointer

Reading literature that indicates this functionality is supportted in the extended c libraries but I keep getting compilation errors.Code:std::string test;test.pop_back(); <- compiler cannot find this call.Does anybody know if it is supported with the gcc version and extended liraries I am using on linux.

It's unsupported and virtually unknown, so I don't know many details about it aside from what I can gather from the source files. The first step in the installation directions is to type "make lib_install" as root at the command line. I get this output:
Making libasymptopia.so ... compiling Path.C ... Path.C: In member function �void Path::listdir(char*, std::deque<char*, std::allocator<char*> >*): followed by a bunch of errors like this: Path.C:38: error: �strcmp� was not declared in this scope
all for the file Path.C, all of them complaining about various header files not being declared. I have the latest version of gcc installed, so I'm very confused about what the problem is. This application is at least a few years old...maybe there's something out-of-date about the way it includes the header files?
I am running Valgrind on my program. It shows me two errors but mentions only addresses against them and not actual code even on a debug build.

i am working with ad hoc network but the problem is not getting any good documentation of how to compile c++ code then how to add the code into Tcl intrepreter and how to work with make file. i want to run my own algorithm using c++ and then want to incorporate it into tcl interpreter and then want to run.

I had been working on a CPP code for sometime now, without being aware that some parts of its code, especially security related were not being compiled. Problem was like my product did not work for SSL mode. On analysis, I found that some part of CPP codes inside a switch(ENABLE_SSL_LIBRARY)were not getting compiled at all. And also that this gets set when we do newgrp crypto command on the box. This left me without lots of doubts. I wanted to understand how these switches work and if this switch was propreitary to my code or something related to Linux.
My questions now are:
1. Switches like the one mentioned above, are they user defined, for my particular code or are they related to Linux/GCC or makefiles?
2.If a user can define such switches to control code compilation, then need to know the concepts/procedures behind it. How is it done ?
Kindly excuse if these are very very basic. But since I could not get proper stuffs on google, I thought I should ask some experts here who could either explain me or point me to appropriate resources (links of articles / tutorials)
Well, either it's bizarre or I'm going crazy. Here is a student's very simple linked-list implementation.
The problem is simply that when the list class is named "link", g++ complains:

I want to compile the the source code given in a well known unix programming book(stevens) .I downloaded the codes but unable to build it ,giving me an errorerror: stropts.h: No such file or directoryI don't know what to do....I am using fedora 11 latest gcc in the system.
I also try to include the search path which include a file -I./usr/include/xulrunner-sdk-1.9.1/system_wrappers but itI open the header file and the definition is there #include_next<strops.h>so ultimately there is not the original file
I'd like to create a target named "debug" or something similar which will use some special optimization flags useful when debugging (for example -ggdb). At the moment my makefile is neat (which I like) and looks like
Code:

INCDIR = -I.

View 11 Replies View RelatedI was trying to write a graph plotting program with c++. I need to convert the infix expression from user to postfix expression for quick evaluation. However, the evaluation of postfix is kind of interpreted, and thus kind of slow for evaluating huge number of values. Say if I plot an implicit function the penalty is quite huge. Is there a way that I can compile the infix expression from my running graph plotting application for high speed evaluation.

I've generated some srt subtitle files using gocr from pgm files used in DVD's. The ocr program gets confused between lower case L and upper case i and sees them as the same thing. This results in words with capital i's in them instead of lower case L.
What is the best way to automate the correction without a spell checker? I tried sed, but it's difficult to tell between the i's that you want and those that need changing. I figured that any word that consists solely of capital i's is ok, e.g. Roman Numerals, but any capital i not at the beginning of a word needs changing.

The 2010 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most widespread and critical programming errors that can lead to serious software vulnerabilities. They are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all.
The Top 25 list is a tool for education and awareness to help programmers to prevent the kinds of vulnerabilities that plague the software industry, by identifying and avoiding all-too-common mistakes that occur before software is even shipped. Software customers can use the same list to help them to ask for more secure software. Researchers in software security can use the Top 25 to focus on a narrow but important subset of all known security weaknesses. Finally, software managers and CIOs can use the Top 25 list as a measuring stick of progress in their efforts to secure their software.

I am trying to modify the source code of a C application (quagga) in order to insert data into a mysql table. I have added 2 new source files to the source (neto_mysql, neto_trend) which in turn use mysql.h. I have also modified the Makefile.am file to include the /usr/include/mysql directory.
When trying to compile, i get the following error. What am I missing? I have minimal experience with formal C applications like this. I feel like I may also have to include the mysql.h file in the libbgp? I dont understand why it cant find the mysql functions...
