>Release: FreeBSD 3.1-RELEASE i386
>Organization:
University of Electro-Communications, Tokyo, JAPAN
>Environment:
FreeBSD 3.1-RELEASE i386 and rpcgen which included in the release.
However it happen in FreeBSD 2.2.8-RELEASE i386 and
seems not fixed yet even in current CVS repository.
>Description:
Generated server side code using rpcgen with -b (Backward compatible)
option can not be compiled. The code includes <stropts.h> and
<netconfig.h>, they are not exist on FreeBSD system.
This option is not useful in FreeBSD since current rpcgen on FreeBSD
is not support TI-RPC features and this option is turned on by default.
However, to compile old programs for ONC RPC, we should compile them
with -b option (existence of this option will be detected automatically
by configure script) for portability.
On current FreeBSD, configure script estimates -b options is available
and generates a Makefile to use rpcgen with -b option, then
the compilation will be failed.
>How-To-Repeat:
Here is a simple sample rpc source (sample.c):
program SAMPLEPROG {
version SAMPLEVERS {
void sample_proc(void) = 0;
} = 1;
} = 10000;
Compile it using rpcgen with -b option:
% rpcgen -b sample.x
Then, compile generated server side code:
% cc -c sample_svc.c
It makes an error:
sample_svc.c:12: stropts.h: No such file or directory
sample_svc.c:13: netconfig.h: No such file or directory
>Fix:
It is came from turning tirpcflag on when -b options is specified.
As described in man page, current rpcgen on FreeBSD can not handle
TI-RPC features and this options should simply be ignored.
The patch should be following:
