I had a similar problem where I needed to compile some code
I was sharing with a non-epics app and I needed to compile it
without -ansi.

Turning it off in epics base config files is asking for trouble as it
will affect all compiles of base, modules, IOC's, etc.

Since -ansi is selecting the language standard, you can't just turn it off
with a compile flag.   Instead, you have to select a different language
standard.    The default gnu std for c files is gnu89, but others are
available as well, such as c89, c99, gnu99, etc.    See the gcc man page
for details.

For my directory that had this problem, I added the following line in that
directory's Makefile after including $(TOP)/configure/CONFIG.

   USR_CFLAGS      +=  -std=gnu99

hi,  Michael:

    so how to solve it? close the ansi switch in epics base's configure files? will it influence the base?

This is an '-ansi' problem.

On my Debian system (libnet 1.1.2.1-2) line 1432 of libnet-functions.h
looks like

    
inline u_int32_t
      
The 'inline' keyword isn't part of ANSI C89 and can't be used when
compiling with '-ansi', which EPICS Base does by default.

Any suggestion?  thanks a lot.
ps, I use ubuntu, libnet1 with apt-get install ,not from source
compilation.

Best regards
