header files missing

[ratheesh kannoth]

I have a 2.6.18  kernel running on an intel machine. I have  gcc 4.1.2
installed on this . There is no header files  like stdio.h on this
machine, so i could not compile any program.

Where and which should i download for all the C developement header
files ?.  i dont apt-get or yum running , i would like to download and
install )

Hi Ratheesh,
did you install the "build-essential package" ?

sudo apt-get install build-essential

I think you are mixing concepts here. stdio.h and others are ANSI C
user-space library headers. These comes with a C library like glibc.
The kernel has nothing to do about it. Unless you want to compile
user-space applications that use kernel headers.

Hi
  What distro are you running? those header are part glibc & glibc-dev
on many distros.

Surely, he has glibc installed, but the issue is  that anything to do with the PATH variable or anyother environment variable settings?

Most distros split libraries into runtime and development packages.
Shared libraries are in the runtime package, headers are in the
development package.

He'll certainly have the runtime package for glibc, but he won't
necessarily have the development package.

Some might use dlopen() and dlsym() in case of runtime library

I suppose the "runtime" here just means shared libraries that is
loaded by dynamic linker (not sth like plugins) instead of those
headers which are not necessary at "runtime". So dlopen() and dlsym()
are not necessary (and probably not possible for glibc).

Ok,
If your custom kernel is on an embedded target you can use ucLibc. If 
you are runing on a host (a PC) you can download Libc6.

But there is a but... these headers are for userland not for kernel dev.
for the kernel dev, download you kernel headers it's something like
linux-headers.2.6.xx-yy

Note: for embedded systems you can use buildroot which will help you to 
download & install all that you need.

Do you mean u r using LFS system? but in that way you should have
header files installed along with binaries (if you just ./configure &&
make && make install)

Otherwise you should have a package manager (Don't know any "real"
distro that don't have it.)

Are you sure you don't have the header file or the compiler cannot
find it? How did you install glibc?
