ext2_fs.h include nigtmare

[ggankhuy]

I have version 4.10 UBUNTU just installed on my pc.
and now I got about 100 lines of error message whenever I included ext2_fs.h file in any *.c file and compile with cc or gcc. Does someone encountered this? Thanks!

well 14 views no response, so I asuume no body has encountered this problem, or nobody knows waht this problem is huh? I think ubuntu is doomed in this sense.

[christhemonkey]

Your using Warty Warthog?


4.10 October 2004 Warty Warthog Unsupported as of April 30, 2006

Maybe you should consider upgrading?
Or is their an explicit reason you wish to use an unsurported out of date version?

Ubuntu is doomed because you're using an archaic version of it and you're having some crazy, obscure problem? Perhaps copy and pasting some of your code would help, at the very least?

[christhemonkey]

And i presume you have e2fslibs-dev installed?


Or linux-kernel-headers?


If not, then its silly linking to a library thats not there.

well, Downloaded 5.04 version installed, still get the same error during compilation.
Here is my main.c file , nothing wrong with that.
==============
#include <stdio.h>
#include <fcntl.h>
//#include <linux/ext2_fs.h>
#include <string.h>
#include <sys/stat.h>
#include <time.h>

int main()
{
printf("Hello World"); //print hello world.
getchar(); //pause
return 0;
}

and here is my makefile:
========================
all : main1.o
gcc -g -o main1.out main1.o

main1.o : main1.c
cc -c main1.c

run : all
clear
./main1.out

clean :
rm *.o *.out

walk :
gdb ./main1.out


Now create Makefile and main1.c and paste my code and put these files under same folder go into that folder and compile <make>. It compiles and runs fine but now uncomment the
//#include <linux/ext2_fs.h> in main1.c and
this is what I get:

Perhaps you guys know waht exactly wrong with it. THanks!

[ggankhuy]

So no one can answer it???

Strange - my initial thought was that you somehow had a corrupt version of ext_2fs.h, but that just doesn't make sense (not least because you're trying a new version of Ubuntu. I compiled your code with the uncommented ext2_fs.h include, and it compiled fine for me. Is there something weird about your system? I notice you're compiling as root, too - which isn't really a great idea. Strange things have happened to me if I compile as root. Try compiling as just a regular user, maybe?

yes i'll try as a different user, I dont think header file is corrupt, since I just dw-d iso and burned and installed right away. happened with 4.10 exact same thing with 5.04.

[ggankhuy]

[QUOTE=christhemonkey;2176486]And i presume you have e2fslibs-dev installed?


Or linux-kernel-headers?


If not, then its silly linking to a library thats not there.[/QUOTE[/B]

e2fslibs-dev<- what is that. Ok i'll check when i get back home. I dont have ubuntu at work,

well i have the ext2_fs.h file in the correct folder and the error messages doesn't say missing file or something. But I went ahead and installed the package you mentioned thru synaptic, but still the same exact error messages. waht the heck.

Stil didn't help. I create different useer and compiled, exactly same result. perplexed.
