[Flex-devel] Re: alloca() problems in flex

[Herbert Y. <Her...@st...>]

Hi,

Currently I am trying to get flex to work under uClinux. Note that this is a 2.4.x Kernel with nommu and it uses the uClibc c library routines. When compiling I am having the problme of __builtin_alloca - namely alloca.c. 
It appears as though flex uses the function alloca() but wants to derive it from the kernel which is non-existant. I was wondering whether there was some sort of configuration in order to remove this or whether I could replace it/remove it completely and instead setup a static stack as uClinux only provides a static stack of 4K.

Thank you in advance for your help,
Herb
