Undefined reference to rpl_malloc

[midaszhou]

Just cross compile espeak-ng for Openwrt, Errors arise at final make stage :

I've deleted lines of "#undef malloc" and "#undef realloc" in config.h.in before, otherwise it would cause "undefined reference to rpl_malloc" error during making. Dose that matter ?

The build process uses the built espeak-ng program to build the dictionary and phoneme data. You could do the following:

1. Build the program locally to build the dictionary and voice data (make).
2. Build the espeak-ng and speak-ng programs with the library using cross compilation (make -B src/speak-ng src/espeak-ng).

The "undefined reference to rpl_malloc" error is an issue with the configure.ac script.

Thanks a lot! It works!
For the 2nd step, I deleted 'AC_FUNC_MALLOC' and 'AC_FUNC_REALLOC' in configure.ac,
then run autogen.sh and bulid.sh again.
I edited build.sh for cross compilation like this:
#!/bin/sh
./configure --build=i386-linux
--host=mipsel-openwrt-linux
--target=mips-linux \

finially run make as ( make -B src/speak-ng src/espeak-ng ).
Its tricky and exiting!
