However, this > issues cuts any Diverse Double Compiling attempt. IIRC, when compiling, SBCL puts the timestamp of the source file in the compiled file. It's not a problem when just doing basic compilation because the source files' timestamps have been set to "1970-01-01". However, some packages generate some source files at build time, usually containing things like data type sizes fetched from system header in order to use C libraries with FFI. The timestamp of a generated file is the current time, therefore the build is not reproducible. IIRC, SBCL itself is built in 2 stages. First its core is compiled using another Common Lisp implementation (currently clisp in Guix), then the complete SBCL is compiled using the core compiled in stage 1. There is probably also an embedded timestamp issue here (coming for clisp, from SBCL, or both) causing the reproducibility issue. The patches currently in the staging branch don't have any effect on the generation of source files or on the format of the compiled files, so they will not help with this issue. Removing this source file timestamp from compiled files would simplify things. Maybe nothing really depends on it and it would be possible...

Do you think it is affordable to fix these timestamps to 1970-01-01? > IIRC, SBCL itself is built in 2 stages.

Still unreproducible. Out-of-scope with this bug report, my aim is to have a fixed point: - first compile SBCL with CLISP (using the 2 stages you describe): produce SBCL-A - second recompile SBCL with the previous SBCL-A (again using the 2 stages): produce SBCL-B - third recompile SBCL with the previous SBCL-B (again using the 2 stages): produces SBCL-C The binary SBCL-A is not deterministic probably because of CLISP (and CLISP should be fixed but that's another story :-)). However, SBCL-B and SBCL-C must be deterministic. And ideally bit-to-bit identical but that's another story. :-) And they are not; from my experiments at least. Even, you could do the same procedure replacing CLISP by ECL, producing SBCL-{A,B,C}-bis. Then SBCL-C and SBCL-C-bis should be bit-to-bit identical. > Removing this source file timestamp from compiled files would simplify > things.
