           Summary: lwip_ppp tests build fails when CYGDBG_LWIP_DEBUG turned
                    on
           Product: eCos
           Version: 3.0beta1
          Platform: Other (please specify)
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: normal
          Priority: normal
         Component: Release Engineering
        AssignedTo: john@dallaway.org.uk

lpc.c uses snprintf() when TRACELCP > 0 (it true if CYGDBG_LWIP_DEBUG option is
turned on). We have not snprintf() there (only diag_snprintf()), so it's not
possible to built lwip_tcpip tests with debug INFRA.

SYNOPSYS

. /opt/ecos/ecosenv.sh 

ecosconfig new pc lwip_ppp
U CYGPKG_IO_SERIAL_DEVICES, new inferred value 1
U CYGPKG_LWIP_ETH, new inferred value 0

ecosconfig import /dev/stdin << EOF
cdl_option CYGDBG_LWIP_DEBUG {user_value 1};
EOF

ecosconfig tree&&make -s&&make -s -C net/lwip_tcpip/v3_0b1/ tests

RFC: What's about s/snprintf/diag_snprintf/g there?

Nowadays I insert a substitution in lpc.c:

#define snprintf diag_snprintf

to be able to finish the build.

Note: CVS has the same bug.

Certainly, I talk about lcp.c. My fingers remember lpc :-)

This is an lwIP issue. Moving to component "TCP/IP".
