need linux tips

[FishBoy]

hey i need help in a couple of things on linux, when i compile a c++ or c program i get the binary file but when i try to open it on the shell (eg: a.out) it tells me bad command name or somethng like that, and also how do i compile in debug mode i remember it was something like gbd? but i odnt know how to use it thx all

if a.out is in your current directory you need to execute it with:

./a.out

unless you added "." to your $PATH with is really bad. Now, for some tips:

c++ file.cpp -o file

will create the executable "file" in your current directory which can be executed like so:

./file

To create a file with debugging symbols built in, you need to add the -g flag to c++

c++ -g file.cpp -o file

Then you can use gdb:

gdb ./file

In GDB you need to type "run" and the program will run, google for tutorials on how to use gdb, as it is a huge program with so many different abilities, that i can't explain them even in 5 replies.

hey how do i get my sound to work each time i load linux, coz everytime i load it ihave to go to SuSE Hardware Tool and delete and re-add the sound card and the card will work again, SuSE Linux 9.1

 

[AcftMecH]

have you tried this:

YasT -> System -> SysEditor -> Hardware -> Soundcard -> LOAD_SEQUENCER = YES

if this one doesn't work. You may have to add a line to the .conf file, but being new myself, I am not for sure what it is called. But it is something along these line probably. Good luck!

 

[FishBoy]

no i had a check box called "start sequncer" which is alwasy checked

 

[FishBoy]

how do i examine an error in depth using gdb
it's telling this:

Program received signal SIGSEGV, Segmentation fault.
0x40184705 in strncpy () from /lib/tls/libc.so.6

that strncpy() worked in another place in my code but i wanna know why it's failling this specific time

EDIT:
well i got it i replace the strncpy() with a for loop to copy the string and i still go the error but this time it told me that i was going out of bound so i was able to fix it

how come ntfs writting on linux is dangerous, how could i make it so i could write to it.

fishboy, for linux help you're in the wrong forum, you should go to:
http://www.linuxquestions.org/ < Here I have found a post (a very often solutions) about my linux problems
or if you're using a fedora distro check out:
www.fedoraforum.org < Even more useful for me than linuxquestions

(No offense to osnn or it's members, for windows and mac togther we're pretty great, but in linux matters we're sub par.)

 

[FishBoy]

no i think X-Istence is pretty good in linux and programming i always count on him when i need help/tips in these 2 things
but yea i know about linuxquestions.org but im more used to this forum i think i did register on that site long time ago

edit:
i'll give it a go though

 

[NetRyder]

Fishboy, this should answer your question: http://linux-ntfs.sourceforge.net/info/ntfs.html#3.2

 

[FishBoy]

oh

The possibility of destroying your filesystem is very high.
...
Make a mistake and the filesystem will be damaged, make too many mistakes and the filesystem will be destroyed.

see how encouraging that is... im getting 2nd thoughs, coz all of my media files are in there lol

cool but there are drivers for ext2 and ext3 for windows

 

[NetRyder]

Yeah, I wouldn't do it if I were you.

 

[FishBoy]

Yeah, I wouldn't do it if I were you.

yea im just gonna try and make a small fat32 partition for like "transfers" between the 2 OS and that should be great

i also posted question on linuxquestions.org if you guys wanna see
Link

 

[FishBoy]

does the disk affect the OS performance and 'stubborness' in anyway? coz my linux seems to not be acting as it used to long time ago and on my friend's computer
