| eclipse always rebuild all object files [message #1791842] |

Hello
I moved my C++ project from eclipse 4.4.2 to the newest eclipse 4.8.0 on a new computer.
The problem is that eclipse now always does compile all files, even when I didn't change anything in the sources.
I can't find a reason for this behaviour, maybe anyone here can help me to fix this. Compiling everything does take a lot of time...
Thank you
Tom

Hi everyone,
The situation keeps happening to me with eclipse 2021-06, as today, 2021-OCT-18
-----------------------------------------------------------------------------------------------------------
This is my .project file
-----------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>

The final part of the makefile:
-----------------------------------------------------------------------------------------------------------
-include ../makefile.defs
OPTIONAL_TOOL_DEPS := \
$(wildcard ../makefile.defs) \
$(wildcard ../makefile.init) \
$(wildcard ../makefile.targets) \
BUILD_ARTIFACT_NAME := asio_timer_asynch
BUILD_ARTIFACT_EXTENSION :=
BUILD_ARTIFACT_PREFIX :=
BUILD_ARTIFACT := $(BUILD_ARTIFACT_PREFIX)$(BUILD_ARTIFACT_NAME)$(if $(BUILD_ARTIFACT_EXTENSION),.$(BUILD_ARTIFACT_EXTENSION),)
# Add inputs and outputs from these tool invocations to the build variables
# All Target
all: main-build
# Main-build Target
main-build: asio_timer_asynch
# Tool invocations
asio_timer_asynch: $(OBJS) $(USER_OBJS) makefile objects.mk $(OPTIONAL_TOOL_DEPS)
@echo 'Building target: $@'
@echo 'Invoking: Cross G++ Linker'
g++ -L/usr/local/lib -L/usr/lib/ -o "asio_timer_asynch" $(OBJS) $(USER_OBJS) $(LIBS)
@echo 'Finished building target: $@'
@echo ' '
# Other Targets
clean:
-$(RM) $(CC_DEPS)$(C++_DEPS)$(EXECUTABLES)$(OBJS)$(C_UPPER_DEPS)$(CXX_DEPS)$(C_DEPS)$(CPP_DEPS) asio_timer_asynch
-@echo ' '
.PHONY: all clean dependents
-include ../makefile.targets
(END)
Any ideas how to sort out of this behaviour?
Many thanks,
-Francisco
