i have a helloworld.c program that I want to compile and link. i managed to compile it and link it but when i run it using:
Hello
at commant prompt it returns with error about package having a Hello and Hello_Debhelper and I use sudo.....?
I coded a simple hello world program to see if I can get something to work on my own in Linux. I used the command "sudo g++ hello.cpp -o helloWorld" to build the executable. However when I am in the terminal (in the right path) and I type "helloWorld" or "sudo helloWorld" it does not run. I look over at google and it told me that I could be in the wrong directory (path) what I am not, or the file permissions could be set wrong. However I looked it up on google as well and I can't see nothing wrong with the file permissions. Hoping someone could lend a helping hand. These are the file permissions as received from "ls -l".

I've been trying to use the library boost/thread.hpp but I cant get it to link. Every time I try it looks like this:

I am stuck with a problem to link static libraries with gcc. There is no problem with source files since I am able to compile in a machine where the static library is installed.

When performing rpm -Uvh, my rpm is not able to link the shared library. My rpm use shared libraries which are created by my software. when i do rpm -ivh everything is working fine My rpm creates the softlinks to the shared libraries.

View 4 Replies View RelatedI am having some trouble when I try to link my custom libraries to target executables. There are two libraries
liba
libb
and an executable exec based on main.o The library libb has some reference to liba. Now if I put the libraries in same directories, I can compile the code as g++ -o exec main.o liba.a libb.a But, if I put the libraries in different directories, say d1 and d2, and use the command as g++ -o exec main.o d1/liba.a d2/libb.a I get an error as undefined reference to some function in liba. I am not sure if I am missing some thing in linking process. Also, if libb doesnot refer any functions in liba, there is no error in either of the case.
In mandriva 2008 platform I have installed gcc-g77, liblapack, liblapack-devel, libblas, libblas-devel, arpack, arpack-devel and arpack-static packages. When I link *.f code and these libraries, using g77 compiler with -llapack -lblas -larpack options, everything work. Then when I replaced g77 by gfortran compiler, to be able to work with double precision complex arithmetic, I have got a number of undefined references errors:

It looks as if I need to install f95 lapack and arpack libraries. Does anybody know if such rpm packages exist? I cannot find them in the net. If they exist, where is it possible to download them?
I'm trying to link the MySQL libraries to some C code, the LambdaMOO server to be exact. I'm getting the following error:

You can see the link commands I'm using, and the lib and include path are both valid. I tried replacing -lmysqld with -lmysqlclient but this did not help. I'm using Debian and MySQL, libmysqld-dev and libmysqlclient-dev are all installed.
Why many Linux distros are trying to use always the latest versions of the libraries and don't save the old libraries for compatibility? I mean, I can see libtiff for example, i can found a libtiff.so.5 on my /usr/lib, but doesn't store a libtiff.so.4 or 3 just for binary applications or games. For this example, I need libtiff.so.4 for uplink.
That should happen too on the old version of sims for linux, some ID games or others.What's wrong with storing old libraries? PD: Yay, my first post on 3 years!
Is there any way to use a dynamic libraries as a static libraries instead when compiling, so that my resulting executable won't have them as dependencies?

View 9 Replies View RelatedI have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf
[Code]....
The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.
log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html
The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.

View 9 Replies View RelatedIn the ordering of files I keep I need links to directories. Sometimes I even need to move directories to new locations. I have tried using symlinks, but they become dead when I move the directory they point to. I have tried hard links, but I haven't found any Linux file system that would support hard linked directories. How can I achieve that a complex structure of directories (currently with symlinks for directories and hard links for files) keep symlinks live when directories are moved?
- is there any utility that updates symlinks when a directory is moved?
- is there any Linux filesystem that supports hard linked directories?
- is there any good Linux interface to the new NTFS (the only file system I know to support automatically updating directory links, called directory junctions)?

What can you do when your linux system "can't find" dynamically linked libraries that are indeed installed in their correct locations? Case in point, I'm trying to run a program called 'ucanvcam':
oliver@human ~/installed/ucanvcam-0.1.6/bin $ ./ucanvcam
./ucanvcam: error while loading shared libraries: libgd.so.2: cannot open shared object file: No such file or directory
oliver@human ~/installed/ucanvcam-0.1.6/bin $ locate libgd.so.2
/usr/lib64/libgd.so.2.0.0
/usr/lib64/libgd.so.2
oliver@human ~/installed/ucanvcam-0.1.6/bin $ ldd ./ucanvcam

How can I tell it to look for libgd.so.2 in /usr/lib64? And more importantly, why isn't it looking there, and where is it looking?

I'll be using a specific example, but really this generalizes to pretty much any binary on linux that can't seem to find its' dependent libraries. So, I have a program that won't run because of missing libraries:
./cart5: error while loading shared libraries: libcorona-1.0.2.so: cannot open shared object file: No such file or directory
ldd sheds some light on the issue:
linux-vdso.so.1 => (0x00007fff18b01000)
libcorona-1.0.2.so => not found
libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.3/libstdc++.so.6

I have a library that I have ported from Windows, and is not a derivative work of Linux. The library is subject to copyright law, and I can't disclose the source. I would like to link a GPL application to this library, and want to know if the linking would cause the library to be GPL. If the library becomes GPL, is there some other way (kernel loadable module?) that I can keep my library from becoming a work of GPL?
