Lost gcc .bash_profile Paths

pmagunia · 05-05-2010, 02:25 PM

Recently I tried compiling a simple Hello World with gcc but didn't have any luck. I got this message:

Code:

junk.c:1:19: error: stdio.h: No such file or directory

gcc was installed and configured correctly at one point but I think I changed the the .bash_profile since then.

I checked where stdio.h lives. The path is:

Code:

~/lib/gcc/i586-pc-linux-gnu/4.4.0/include/ssp

The following is my current .bash_profile. I changed some of the absolute paths to '~' for security.

Code:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
CC="gcc"
PATH=$PATH:$HOME/bin:/usr/bin
cd $HOME/html
LDFLAGS=-L/~/lib
CPPFLAGS=-I/~/lib/gcc/i586-pc-linux-gnu/4.4.0/include

export CPPFLAGS
export LDFLAGS
export PATH
export SBCL_HOME=~/lib/sbcl

I think at some point there was an LD_LIBRARY_PATH's path too.

Here is the contents of my hello world program:

Code:

#include <stdio.h>

main()
{
  for(;;)
      {
          printf ("Hello World!\n");
      }
}

I am not sure what to do. If somebody could help solve this problem for me I would appreciate it. Thank you

Clarification-- are you setting your actual paths to 'LDFLAGS=-L/~/lib' for example or for an example 'LDFLAGS=-L/var/lib'? Also as an aside, obfuscating paths... waste of time. passwords, ip addresses, etc... sure worth the effort often more for sake of privacy than security but... paths-- not so much. Your stdio.h should probably be /usr/include/stdio.h or something very similar. My real question is... why are you changing all this and messing with it if you have no real understanding of how it works and the defaults typically work flawlessly (provided you actually have what you need installed.)

The LDFLAGS path I have is absolute. I used the tilde to cover up the path to my home directory. In actuality it starts with '-L/home/...'

The reason I am asking is because the software is all on my server: I only have a basic hosting plan without access to 'make' or tools like 'yum'. I can not install software by the usual means.

So I recreated the home directory path on my home computer and compiled everything at home, and then uploaded these files to the server. It worked: I have working versions of Maxima and R on my server now. They are still working but I can't seem to compile anything. Which is where I was hoping someone could help me do. When I compiled the software at home I made sure there were no other development tools other than what was available in my home directory

I tried a variety a ways but nothing seems to compile without errors. I gave an example of what I tried in the first post. I would like to be able to compile something at least. A simple 'hello world' would be a great start.
