Im trying to install a package. Here's the way Idid it on my system:

cd ~
tar -xzvf TurboC-dev.tar.gz
cd TurboC-source
make
su
ln -s *.h /usr/include
ln -s TurboC.a /usr/lib
exit

and then I tried to compile the source code:

root@r0ot:/home/user/TurboC-source/Programs# g++ -o Test Test.cpp -lTurboC -lncurses
/usr/lib/gcc-lib/i486-slackware-linux/3.2.3/../../../../i486-slackware-linux/bin/ld: cannot find -lTurboC
collect2: ld returned 1 exit status

Also I typed:

root@r0ot:/home/user/TurboC-source/Programs# whereis TurboC
TurboC: /usr/lib/TurboC.a /usr/include/TurboC.h

What Could be the problem?

Thanks a lot.

Which distro of the many listed is this for?
Were the steps you did found in the README or INSTALL file and are the the paths/versions correct for your system?
Was the step ./configure mentioned in either of the above files?

Yeah About Distro is Slackware 9.1, About the README file, that the steps that said, and about ./configure.. There are not Configure file..

what Im doing wrong?

Thanks again..

Do you have the X header files and libraries installed and does the aformentioned makefile agree with their locations?

I think the previously posted checkinstall link is for Slackware and that may help with your dependencies if you are missing them.

What do you mean with the X header files and libraries installed with MakeFile locations? How can I know..?

Do you think I need to reinstall it?

I mean you need all the stuff installed on your system in order to compile stuff that is being built for usage in X (your gui). As far as "Do you think I need to reinstall it?" is concerned, I have no idea of what the "it" is and I am not being Clintonesque with that answer.

Look at man <command> or info <command> for the flags I used and for other options you can use for bash commands.

I have no idea if you installed them or not. You are in front of your computer and mashed the buttons to do the install, so I would have to know what you installed. There are automatic selections (possibly) during installs of most distros (I haven't used Debian yet), so if you selected that, you probably didn't install it.

Debian uses apt-get to control packages and the gui front end is synaptic. Configure apt-get so that it knows about internet sources (it probably only knows what CDs you have), then do
apt-get update
apt-get dist-upgrade
When this finishes, what you have installed will be updated.
Try an apt-get install

After seeing you are attempting to install a DOS compiler, I was wondering why if you are going to run Debian, you have a perfectly good GCC.

You sound as if you may need info on the Linux filestructure, so hear are some links for that as well.

Thanks a lot. Now is working fine.. In order to get it to compile, I had to use the following:

gcc -o Fact Fact.c -L/home/user/TurboC -lTurboC -lncurses -L/usr/X11R6/lib
-lX11 -lpthread


Thanks again..

Yay! Another Slackware distribution (of which I know little or nothing) help with something I know absolutely nothing about.

I am still wondering (nosey might be a better term). You just installed a DOS compiler and I was wondering why? If you are going to run Debian or any other Linux, you have a perfectly good GCC available.

Yeah I installed a DOS compiler cause a long time ago I coded a Large Sales Program, and recently I needed a project similar working on Linux, and I thought ok I will try to port GCC code.. That was the reason. But Dont worry Im currently coding on GCC.. No more M$ Windows compilers..

I have often wonderd how the GNU stuff was ported to Windows. So you are attempting the reverse? Porting to Linux?

Let us know how it goes.

What do you mean with 'GNU stuff was ported to Windows'?

Stuff like I got on this CD: GNUWin II

Nop nothing like GNUWin II . I just wanted to compile it cause I needed to test for a personal project .. Dont worry now Im coding my project 100% on GCC.
