[avr-chat] avrdude build problem

[Erik Christiansen]

Due to my main machine being without a motherboard, I'm building
avrdude-5.10 on a ubuntu 8.04 box. (The avrdude package for ubuntu 8.04
is too old to support xmega)

Looking into this error:

address@hidden:/usr/local/src/avrdude-5.10$ make
make  all-recursive

I tried running the Makefile line manually:

$ /bin/bash ./ylwrap lexer.l .c lexer.c --
./ylwrap: line 110: : command not found

Adding a diagnostic line to ylwrap:
                           case $# in
                             0) echo \>"$prog"\< "$input"
                                "$prog" "$input" ;;

I now have:

$ /bin/bash ./ylwrap lexer.l .c lexer.c --
>< /usr/local/src/avrdude-5.10/lexer.l
./ylwrap: line 111: : command not found

i.e. $prog evaluates to a null string.
That is already the case at line 93:   prog="$1"

Ah, $(LEXCOMPILE) is what's missing, which means that all of:

$(LEX) $(LFLAGS) $(AM_LFLAGS)

are null. (Coulda seen that immediately, if I'd looked. Hmpf.)

So my question is: How should these Makefile lines populate those
variables?:

LEX = :

Oh, there are no Makefile lines defining LFLAGS or AM_LFLAGS.

So, maybe it's configure which dunnit? (But it ends with:

configure: exit 0

In config.log, the only lines containing "LEX" are:

LEX=':'
LEXLIB=''
LEX_OUTPUT_ROOT='

Should I just finish reconstructing my ubuntu 10.04 host, and try to
build avrdude there?
