Programming :: Setting For Header File And Library?
May 8, 2010I have 3 files: main.c, mylib.h, mylib.c Now I want to put mylib.h into : /usr/include/mydir/mylib.h And I create a static library: libmylib.a, and put into the folder: /usr/lib/mydir/libmylib.a Then I compile: $ gcc -o main main.c Then I got linking error
Code:
main.c:(.text+0x3e): undefined reference to `extract_v1'
main.c:(.text+0x7b): undefined reference to `modify_v1'
collect2: ld returned 1 exit status
So I try with -l options: $ gcc -o main main.c -lmylib I still got error
Code:
/usr/bin/ld: cannot find -lmylib
collect2: ld returned 1 exit status
Any idea about this?
Also, I want to ask about: how to create my own header and library to put into /usr/include/mylib/ and /usr/lib/mylib/, so when I use function in my program, the compiler will automatically link to library. It's like when you #include <stdio.h>, and you compile: $ gcc -o program program.c, you don't need to specify any linking folder or library.

Programming :: Header File Which Support OpenOffice Writer At RedHat4
Jun 9, 2010I need to know the header file used at 'c' to support openoffice writter at REDHAT4. I plan to write a c++ program for something like spellbee game. so instead of giving a txtfile which has a list of words as a source for the game I decided to use some header file. My assumptions are: Since the redhat4 is written through the "C" language and as well as the openoffice writter which is a supporting package at this os too might have the linker right. At openoffice writter we have the spellcheck feature which might had a source from where it checks the words whenever we type something at openoffice writer. So is it possible to use those header file or linkage source at my c++ spellbee game program instead off creating the list about few bunch of words.

Mar 30, 2010I've been trying to find a way to take a bunch of jpeg images and while maintaining their quality (no loss at all) compile them in such a way as to make one coherent file. Maybe something like a pdf, but while maintaining quality. I've tried converting to pdf and djvu, but the quality is always reduced, but if you know of a way to preserve quality, I'll use it.An alternative is an image viewer that can look inside archives, so I just make a zip or tgz of the images and then use the image viewer to access them.

Mar 10, 2010I have been a predominant Windows user for a long time but shifted to Ubuntu recently. I was just trying out a few basic C functions when i realized that the "conio.h" header file isn't included in the libraries and therefore i was unable to use the "clrscr()" function.
I downloaded a tarball which contained the necessary library and header files including conio.h. Once extracted, i specified the location and included in the program as " #include "path to the header file" ".
I still didn't call the "clrscr()" function, and it compiled successfully. Next i edited the program to call that function and it gave the following error...

#!/usr/bin/perl
and this on the footer:
print "

so that i dont have to type everytime #!/usr etc i tried to do it this way but i get weird vim errors: header is a file that contains the header and footer $ vim hello.pl;header > is there another way to do it as a function in bash or some other one liner command?

Programming :: Put Header Files For A Shared Library?
Feb 26, 2010I have written a simple library and ended up with a .so file. I have a header file from writing the code that describes how to use the functions in the source code I have written. I think this .h files needs to be available to other programs that access this code.
I have seen lots of tutorials on how to copy the .so file to the relevant directories and make links with the version number. What I can't find is where to put the header file so that any programs I write to use my new library can access the header.
Hope this makes sense. For example, I might use <stdio.h> normally, I will need to access <mylibrary.h> once mylibrary.so is loaded (as far as I understand!)
It's weird, I've been using C compilers for embedded processors over ten years now and never given a second thought to how libraries and headers work behind the scenes!
