Formal way of using Nuttx-Posix libraries
Hi,
I am doing experiments of porting standard posix applications to Nuttx, I try to run same applications on both Ubuntu and Nuttx. In one application I needed to use socket.h, I did "#include <sys/socket.h>" in my c file but it seems that the linker doesn't find the library, I get "undefined reference to `socketpair' 'send' 'recv' errors while all of them clearly defined in sys/socket.h !
Of-course I can modify the c file, Makefile, I can move or copy library files to appropriate locations to resolve the problem, but I would like to learn the formal (preferred) way of resolving this issue on Nuttx
because the same code compiles and runs on Ubuntu without any modification other than removing <nuttx/config.h>.
BR

This is not an answer to your question (I'm not sure why that is happening
and away from a computer so I can't try to reproduce it now) but just
wanted to point out that you don't have to remove the #include
<nuttx/config.h> even when compiling on Ubuntu or other OS. You can wrap
that include with #ifdef __NuttX__ ... #endif. The toolchain built with
NuttX's buildroot defines that symbol, and if you use other toolchains you
can add this define to the compiler command line in your board's Make.defs
file. Then you can build the exact same source file without modifications
or the need to maintain separate branches. (Caveat: I'm writing this all
from memory so it's possible some of the names aren't exactly correct, or
I'm forgetting some detail.)
Hope this is somehow helpful and that you will discover the solution to
your actual question very soon...
Cheers,
Nathan

Thanks for your kind answers and help, I always appreciate.
@Alan OK I will try using USB console according to your tutorial to continue my experiments.
@Nathan yes I already removed #include <nuttx/config.h> and I don't have problem in Ubuntu, my code compiles and runs as expected. I am also aware of that this issue has been many times before however I couldn't resolve the issue, but working on it. I will try to get help from your explanations.

How to search for configs in the Kconfig files:
Option 1, interactively in the ncurses-based menuconfig program:
Unless this depends on locale settings, the '/' (forward slash)
character brings up a window where you can type in a config name to
search for it; pay attention to the NOTE below...
Option 2, grep for these identifiers through the Kconfig files
themselves. Note that these files are located in various places
throughout the NuttX and apps trees, so you need to search recursively
using your favorite grepping tool.
NOTE: If a config option is called CONFIG_FOO_BAR in source code, it
is called FOO_BAR in Kconfig, so omit the CONFIG_ prefix when
searching. Alternately you can grep for search terms in the Kconfig
files themselves.
Kconfig options often depend on other Kconfig options, so you need to
verify that you have the dependencies. Option 1 is easiest for this,
since the menuconfig program will show you the dependencies for an
option when you search for it, or when you bring up the help about it.
It will say "depends on" and list out all the dependencies, with their
actual values. So if something doesn't even show up in the menus, look
carefully at the dependencies shown by the program and determine which
one(s) are not configured that should be configured.
Hope this helps,
Nathan

Hi Alan, I did.
This way I could compile and run my code on Nuttx but I now get "Socketpair creation error" from my program.
As far as I know socketpair fucnction was includded in Nuttx 10.1 but I can't see its reference in the latest Network documentation here: https://nuttx.apache.org/docs/latest/reference/user/11_network.html
Anyway, I got some progress.

Hi Murat,
Just use the netnsh config and follow my video tutorial explaining how to
use USB Console.
It is easy when you know which options to look at on menuconfig. It is
important to get used to menuconfig, otherwise it always will be like a
maze.
BR,
Alan

I wish there was an easier way to configure the Nuttx; it is really hard!
The application I wrote with the :netnsh configuration was compiled without any problems. However I want to use /dev/ttyUSBx as >nsh console. I'm trying to compare nsh and netnsh .config files to do something, but it's really complicated.
How can I go further .. :(
