Re: How to compile tcp fast open client app with kernel tfo client support ?

htmlgettfo.c: In function 'get_page_thread':
htmlgettfo.c:109: error: 'MSG_FASTOPEN' undeclared (first use in this function)
htmlgettfo.c:109: error: (Each undeclared identifier is reported only once
htmlgettfo.c:109: error: for each function it appears in.)

I have the 3.6.0 kernel header file package installed
/usr/src/linux-headers-3.6.0-custom, the user space include file
/usr/include/linux is original one coming with 10.0.4 distro kernel

I am suspecting I don't have proper linux header file that has
MSG_FASTOPEN declared in user space. can anyone shed a light on how to
get MSG_FASTOPEN supported and compiled in client code properly?

Vincent ,
You can try adding the following to the client code.

#define MSG_FASTOPEN    0x20000000

This is missing still from user space header files I presume.
