Hi I just installed ubuntu on my acer travelmate 2303lc. All went well. But i need til compile intels tool for acpi support to get my battery working. But when i type make, there is an error:
root@ubuntu:/home/peter/acpica-unix-20050624.tar.gz_FILES/acpica-unix-20050624/compiler # make
cc -Wall -O2 -Wstrict-prototypes -D_LINUX -DACPI_ASL_COMPILER -I../include -c -o aslcompilerlex.o aslcompilerlex.c
aslcompiler.l: I funktionen 'comment':
aslcompiler.l:847: error: `yytext_ptr' undeclared (first use in this function)
aslcompiler.l:847: error: (Each undeclared identifier is reported only once
aslcompiler.l:847: error: for each function it appears in.)
make: *** [aslcompilerlex.o] Fejl 1
What does it mean???

It looks like you need to install flex. You'll probably need bison too
apt-get install flex,bison
