/usr/include path issue

[Gabor Alsecz]

Hi All,

I am using the latest cygwin installation and I have an issue with my
/usr/include directory under cygwin bash.

my .c file snippet looks like this:

#include <netdb.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

And when running gcc from bash with the followin command:
gcc getip.c

i receive the following error:
fatal error: netdb.h: No such file or directory

So how can i add the fine include directory path to the compiler or
cygwin bash to find the .h includes?

Same issue (include .h file(s) not found) when i try to
compile/configure Kannel under cygwin

Regards,
Gabor

Hi Gabor,

do you actually have a netdb.h ? What does

$ find /usr/include/ -name netdb.h

print ?


You can check which directories gcc searches for include files by
adding the -v switch to the gcc command line:

gcc -v getip.c

netdb.h is part of the cygwin package (according to
http://cygwin.com/cgi-bin2/package-grep.cgi?grep=netdb.h) which is
always installed; it should be in /usr/include, which is searched by
gcc by default.

it works fine, command print the /usr/include/netdb.h

gcc -v getip.c

print all directories included but /usr/include folder missing

Sounds like you aren't using the Cygwin version of gcc:

I get a different error from yours when gcc can't find an include
file, so I'm wondering if it's not a /usr/include path issue, but
something else?
