Compile problems

I’m trying to compile the mongoose library in my TI ARM LM3S9D96 project. I defined the pre-compiler switch STM32 since it is the one that is closer to the Stelaris LM3S9D96 Cortex-M3. I get tons erros “xxx.h file cannot be found” ? Why so many .h missing ? I downloaded the mongoose-master.zip package from cesanta.com web site. Is anybody have a clue ?
