this is probably because of a bug!? in cygwin make. i stumbled on it myself a few weeks ago. if you have recently updated cygwin go back to the earlier version. the bug is due to that make can't handle paths with spaces in it. /niklo
----Ursprungligt meddelande---- Från: [EMAIL PROTECTED] Datum: Sep 26, 2006 8:30:08 AM Till: [email protected] Ärende: [avr-gcc-list] Makefile problem and solution Hi, in the middle of a running project I received from make the "very expressive" error message: .dep/blcd.o.d:1: *** multiple target patterns. Stop. I'm using WinAVR + Cygwin together. My "Unix tools" are from Cygwin while the avr-gcc comes from WinAVR. That works fine except for avr- gdb which I'm not using. I did some updates Path, Cygwin,... so I could not say why a formerly running makefile did run any longer. I found a newly make extension called remake. remake is a make + debugging interface. Very usefull but it did not help. With gdb and the make sources I found out that the under cygwin generated dependency file contain colons that are confusing the makefile parser! Exapmle from blcd.o.d: blcd.o: blcd.c C:/WinAVR_20060421/avr/include/stdint.h \ C:/WinAVR_20060421/avr/include/string.h \ c:\WinAVR\bin\../lib/gcc/avr/3.4.6/include/stddef.h studio/global.h \ studio/defines.h studio/types.h studio/blcd.h studio/lcd.h studio/lcd.h .... The Solution is simple: There is a define "HAS_DOS_PATHS" that need to be set. With this define set the parser is running properly. It seem to be a wrong compiling for the current Make.exe (version 3.81- 1 as defined by Cygwin Setup). But additionally all projects that are moved from Cygwin to Unix will show the same message. For these project the dependency directory need to be removed manually while the next rebuild solves the problem.
