Hi, I am copying this question I already asked on stackoverflow (no reply so far)(stackoverflow.com/questions/18213461/run-makefile-generated-by-eclipse-from-command-line-after-updating-code-not-work):
I'm running
eclipse juno Service Release 2 Build id: 20130225-0426 with this CDT config: dl.dropboxusercontent.com/u/1414360/CDTconfig.png
and this OS:
(truncated output of uname -a): Linux 3.2.0-51-generic #77-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux
I create a HelloWorld C++ project as follows:
File->New->C++ Project
Project type: Executable Empty Project
Toolchains: Cross GCC
Configurations: Debug and Release checked
Then I create a C++ source file Main.cpp that contains hello world code.
I can then compile using the hammer icon. I choose to compile in Release mode. The program runs fine (inside eclipse or at the command line) and prints "hello". If I modify the code to print out "hello there", I can recompile with the hammer and the program still runs fine and prints out "hello there".
However, if I modify the code to print out "hello there you", go to the Release directory (/home/user/workspace/HelloWorld/Release) and type make, I get this message: make: Nothing to be done for 'Main.d'.
There is a file called makefile in the Release directory, but it's not behaving like a normal makefile. I would expect this makefile to be such that when there is a change in the code and you type make, the code gets actually recompiled. If I type make clean followed by make, the code gets recompiled but this is inefficient for larger projects.
Do you know why the makefile generated by eclipse is behaving this way ? Thanks very much.
