Hallo,

ih habe Quelldateien in zwei Verzeichnissen.
Eins ist src und eins lib.
Meine main. ist in src und mein uart. in lib
Beim aufruf om Makefile wir main.c compiliert und ein Object erstellt
uart.c wird auh compiliert aber das object kann niht erstellt werden.
Was muss man im Makefile eintragen damit der ompiler aus verschiedene
Verzeichnissen Dateien compilieren kann?

Poste mal deine Makefile und die Fehlermeldungen.
Meine Glaskugel ist mir heute morgen vom Tisch gefallen.

Hir nochmal mein sr listing im makefile

Ich hab zwar nen Grund für die Fehlermeldung, aber leider keine Lösung 
(eher einen Workaround), da ich vor dem selben Problem stehe.

Der Compiler kompiliert die angegebenen Dateien und schiebt die 
erstellten Objekte in das "obj"-Unterverzeichis. Fall dieses nicht 
existiert, wird es vorher angelegt.
Der Linker versucht jetzt die ganzen Objektdateien zusammenzubinden, 
findet im obj-Verzeichnis aber nicht die erwartete Verzeichnisstruktur.

Workaround: Im Verzeichnis obj die Unterverzeichnisse von Hand anlegen. 
Ein make clean überleben die sogar auch.

Eventuelle Lösung: Dem Makefile beibringen alle Pfadangaben in der SRC 
Variable auseinanderzunehmen und die entsprechenden Unterverzeichnisse 
zu erstellen.

Zweite Lösung: Rekursive Makefiles

Das alles war mir aber bisher zu viel Arbeit und ich habe zu wenig mit 
Makefiles im speziellen gemacht, als dass das für mich "mal eben" 
gemacht wäre Da bin ich beim Verzeichnisse anlegen geblieben.

Aus dem Artikel 
http://www.mikrocontroller.net/articles/Beispiel_Makefile
aus dessen Abschnitt Beispiel 2

%.o : ../../../lq/%.cpp
  @echo compiling special input=$< output=$@
  $(CC) -c $(HJH_IDIR) $(CFLAGS) $< -o $@


Damit ist die Quelle nicht hier, sondern in ../../../lq

Der Objektfile kommt trotzdem hierher (weil -o verwendet wird)

Für dein Problem wird stattdessen ../lib/%.c als Angabe richtig sein.

hab die lösung

$(shell mkdir ../lib/$(OBJDIR) 2>/dev/null)

hinzufügen. dadurch wird  das verzeichniss erstellt
