Where is sys/types.h located?

Question

I just found out that the and headers are located in the /usr/include folder in Ubuntu server, but I don\

Answer 1

Just for future reference, I ran into this problem on my debian machine, and it turned out that in my case

$ apt-file find /usr/include/sys/types.h
libc6-dev-i386: /usr/include/sys/types.h

libc6-dev-i386 is the package I seemingly need to install

Answer 2

My Debian box (and hopefully Ubuntu haven't butchered it too much in their zeal) has it in /usr/include/sys/types.h.

Your best bet is to first execute:

find /usr/include -name types.h

then:

find / -name types.h

if you don't find it in the first one.

However, keep in mind that the development stuff may not even be installed. I would imaging a server box is meant to be used as a server and it wouldn't surprise me if the compiler and a bunch of other stuff was not part of the default install (but it would have a lot of server things like ftpd or Apache and so on).

If the compiler is locating it somewhere and you just don't know where, you can use something like:

echo "#include <sys/types.h>" | gcc -E -x c - | grep /types.h

to find out where it's getting it from.

Or:

echo "#include <stdio.h>" | gcc -E -x c - | grep /stdio.h

for the other header you're worried about.

Aside: That gcc command line stops after the pre-processing phase (-E), forces the file to be treated as C source code (-x c) and retrieves the program from standard input (-), in this case from the echo statement.

The final grep just strips out the unimportant lines.

If you have locate command available you can simply use locate:

-bash-3.2$ locate sys/types.h
/usr/include/sys/types.h
/usr/lib/syslinux/com32/include/sys/types.h
-bash-3.2$

It's the quickest and simplest way to do it.

Answer 4

On Linux, types.h should be in /usr/include/sys/types.h.

Answer 5

The file sys/types.h is located at the /usr/include/sys/types.h

if u get this kind of Fatal Error:

.../linux/linux_types.h:146:38: fatal error: /usr/include/sys/types.h: No
such file or directory

Fix by using the following code:

sudo apt-get install build-essential flex libelf-dev libc6-dev-amd64 binutils-dev libdwarf-dev
