[lwip-users] `MEMP_NUM_PPP_PCB' undeclared here (not in a function)

[markus . forrer]

Hello

I updated lwip from 2.0.3 to 2.1.2 and get the following build error without 
any modifications:

/lwip/src/core/memp.c(79):
/lwip/src/include/lwip/priv/memp_std.h(102): `MEMP_NUM_PPP_PCB' undeclared here 
(not in a function)
/lwip/src/include/lwip/priv/memp_std.h(102): size of array 
`memp_memory_SYS_TIMEOUT_base' has non-integer type
/lwip/src/include/lwip/priv/memp_std.h(102): `MEMP_NUM_PPP_PCB' undeclared here 
(not in a function)
/lwip/src/include/lwip/priv/memp_std.h(102): initializer element is not constant
/lwip/src/include/lwip/priv/memp_std.h(102): (near initialization for 
`memp_SYS_TIMEOUT.num')

Thank you very much for some hints.

Best regards
Markus
