Programming :: Where To Put Headers And Cpp Files
Mar 14, 2010I have several classes that I use for multiple programs. Where should I keep the h/cpp files so I only have to add the #include for the compiler to find them?

Programming :: C++ - Calling Functions From Other Files And Headers?
Apr 11, 2011I feel like there should be a cleaner way of doing this. I have one file, for example "a.cpp", calling a function from another file, "b.cpp". Currently I have it set up so that header for "b", "b.h", has the declaration of its functions. And then I'm just including "b.h" in "a.cpp". Do I have to include the "b" header file in "a" to be able to call a function from "b"? Or is there a better way I could be doing this? Like doing something different at compile?

Programming :: Including Headers Recursively - Is It Right?
Jul 29, 2010Say, I have a header file containing all required includes:
Code: /* global.h */
#include <stdio.h>
#include <unistd.h>
...
#include <dirent.h>
#include <signal.h>
... /* and so on */
I have several modules in a program (*.h *.c files) and in each *.h I include global.h, then they are included in corresponding *.c files. And I receive strange messages from compiler, like a "warning: implicit declaration of function fdopendir", "error: expected declaration specifiers or '...' before 'siginfo_t' ", "error: 'DT_DIR' undeclared..." though these types, functions and constants are all declared in system headers. What does it mean?... Compiler is GCC 4.4.4-2, system is Fedora 13 x86_64

View 9 Replies View RelatedDebian :: Finding Kernel Headers Files Difference?
Jul 3, 2009I usually custom compile my kernel and generate the header files with the following command:
Code:
fakeroot make-kpkg --initrd --append-to-version=generic-ide kenrel_image kernel_headers
However, I noticed that there are some difference in the headers files that get generated with the above command as compared to the header files that are available from Debian repo. For example, the header files for 2.6.24 kernel have files like:
Code:
debian:/usr/src/linux-headers-2.6.24-etchnhalf.1-686/arch/x86# ls Kconfig Kconfig.cpu Kconfig.debug kernel Makefile Makefile_32 Makefile_32.cpu Makefile_64 However, if I custom compile the above kernel from Debian sources (2.6.24), the headers files does not have the above files:
Code:
debain:/usr/src/linux-headers-2.6.24-generic-ide/arch/x86# ls
boot ia32 Kconfig.cpu kernel lib mach-es7000 mach-visws Makefile mm pci vdso xen
crypto Kconfig Kconfig.debug lguest mach-default mach-generic mach-voyager math-emu oprofile power video
As you can see from above output, files like Makefile_32, Makefile_32.cpu are not present, if I generate kernel headers files using the make-kpkg command as mentioned in the beginning of the post. I happened to notice the above issue, while I was trying to compile a out-of-tree kernel module and the "make" command for those sources (some graphics card drm module) worked with the default header files (linux-headers-2.6.24-etchnhalf.1-686) but did not work with (linux-headers-2.6.24-generic-ide) because it did not find the Makefile_32. Although I was able to fix the problem by copying the Makefile_32 from linux-headers-2.6.24-etchnhalf.1-686 but I would like to know why there is a difference. This is bit of a concern because it unnecessarily breaks the out-of-tree module compilation process because of trivial reasons.
Programming :: Build Module Against Headers That Are Not From Running Kernel?

Software :: Which Headers Are "The Headers"?
Jun 14, 2010been a programmer for a while; on windows mostly but I'm starting to learn all that I can about linux software.I've picked up a funky little NAS which has ssh access to its (i believe uLinux) environment. I've also managed to find a compiler for it (gcc compiled for ARM - GNU/Linux).The plot thickens.I've had some headaches but I've now managed to compile Apache2 without DSO support... so far so good.In getting this far I've been told by a number of people i will need "the headers" specific to the device (the NAS didn't come with source code).
Since Apache 2 (without DSO) compiled fine I know i definitely have some headers. But DSO won't build with errors that lead me to believe it may be a header issue.The question:So i have some headers which educated guess work suggests to me that these are the headers for the std c/c++ libraries.finding "the headers" to know what they are the headers for
Programming :: Command For Find/Replace In Text Files (inc. Files In Sub-folders)?
Oct 11, 2010I found this command that works great finding and replacing a simple string to another in files located in that folder and all sub-folders.
Code: find . -name '*.php' | xargs perl -pi -e 's/OldText/NewText/g'
The problem I have is that I need to replace a more complex string, like this: Old string: /mnt/stor6-wc2-dfw1/627896/982574/ New string: /mnt/stor8-wc2-dfw1/369587/302589/ There I don't know how to do it... since the / is what separates the old from the new strings, and the strings that I want to replace have / in it. Also, I would like to know how to specify under what folder replace the files, for example, I want that it search/replaces all files under /var/www/mysite/htdocs folder.

Programming :: C Header Files And Object Files ?
Sep 18, 2010When is it good to use separate translation units and object files and link them into the main C program, and when is it good to include the header files in the main C program? I don't understand if most people include header files or if most people just link in object files and use their contents in the main program. It's sort of a simple question, but it's confusing to me and that's why I need help with it. I sort of don't understand the difference, or if there's really no difference other than the way the final result is achieved, which way is better or preferred, etc...
For example:
Code:
or:
Code:
Simple explanation of the difference? or which one is preferred or better? I've read a little on the ELF format... so is there no difference in the end result? It's just a matter of preference or necessity, and where the information is to begin with?
