Support Forum » Dont edit the makefile with Notepad

I edited the makefile with notepad and it messes it up, probably removes the new lines chars sine the carry return is missing

were these files created in Unix/Linux/Mac?

so it it gives you an error like C:UsersLUISGA~1AppDataLocalTemp/ccquwCKt.o: In function main': C:\NerdsKitSourceCode\initialload/initialload.c:29: undefined reference tolcd_init'

it can't find the references to the libs because the makefile is messed up

heads up

perhaps your Notepad has removed tab characters from the Makefile. It needs tabs after the target specification:

target: dep1 dep2 dep3 ...

Make sure that the tabs are still there, eight spaces won't do the trick.

Also, your error seems to be with the C code itself, not with the Makefile; make sure that you have

#include "../libnerdkits/lcd.h"

in initialload.c, and that initialload.c resides in a directory on the same level as libnerdkits/.

it was not the tabs, or maybe the encoding of the file changed for 8 bit to 16 bit chars.

because of C:/Users/LUISGA~1/AppData/LocalTemp/ccquwCKt.o: In function main.....

it's a linker error.

the way I solved this yesterday was to copy the Makefile again and edit it with the code editor.

you're right, I wasn't reading carefully:

C:\\Users\\LUISGA~1\\AppData\\Local\\Temp/ccquwCKt.o: In function main: C:\\NerdsKitSourceCode\\initialload/initialload.c:29: undefined reference to 'lcd_init'

indeed, a linker error. Probably lcd.o wasn't getting linked in with the rest. Glad you solved it!
