[avr-libc-dev] RE: Probs building avr-gcc

[leehj]

Hi,

I have actually have the same error of :-

configure:2341:17: error: gmp.h: No such file or directory

when I tried compiling gcc-4.2.1 with a separate BUILD folder apart from its
source file folder.

I did ../configure --prefix=/local/gcc/gcc-4.2.1/

but when I do a make bootstrap, the above error is displayed in config.log.
And i just coudl not proceed. Please advise what I could do.



Thanks.

Rgrds,
Jason
