"sys\/types.h 位于何处？"

Question

I just found out that the <stdlib.h><\/code> and <stdio.h><\/code> headers are located in the \/usr\/include<\/code> folder in Ubuntu server, but I don't find sys\/types.h<\/code> .

Answer 1

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 ( -xc ) and retrieves the program from standard input ( - ), in this case from the echo statement.

The final grep just strips out the unimportant lines.

Answer 2

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

Answer 3

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

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 5

在Linux上， types.h应该在/usr/include/sys/types.h 。

Answer 6

在我的Slackware中，我需要安装glibc来解决这个问题。
