RE: Can OProfile support reproducible build?

Hi,
I use the latest version 1.2.0. And I found that the code below would generate timestamps----just they cause the difference.
How

    libutil/op_version.c: 
                    21: printf("%s: " PACKAGE " " VERSION " compiled on "
	                22：__DATE__ " " __TIME__ "\n", app_name);
           
	pe_counting/ocount.cpp:
                        659: case 'v':
			            660: cout << argv[0] << ": " << PACKAGE << " " << VERSION << " compiled on " << __DATE__
			            661:<< " " << __TIME__ << endl;

	pe_profiling/operf.cpp: 
                      1344:case 'v':
			          1345:cout << argv[0] << ": " << PACKAGE << " " << VERSION << " compiled on " << __DATE__
			          1346:<< " " << __TIME__ << endl;

How can I eliminate the timestamps?

主题: Can OProfile support reproducible build?

From [email protected]:


Hi,

When I build Oprofile, I find the build results are different every time. It seems to be caused by some time stamps. How can I get rid of the time stamps?

As we know, reproducible build is a good way to counter malicious attacks that generate malicious executables, by making it easy to recreate the executable to determine if the result is correct.  How can I eliminate the differences caused by the time stamps? Just remove some code? Or is there any configuration?

Can Oprofile support reproducible build in later versions?

Thank you.

Hi,

It would be helpful to describe in more detail which version of OProfile is being built, how OProfile is being built, and specific differences between the repeated builds.

Debian does have some information on techniques on indentify reproducible build issues and ways to address them:
