Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
adacgi could not be built reproducibly.
This is because it installs /usr/share/gpr/adacgi.gpr that contains
the build flags that it was built with. This causes a problem because
these contain the current build directory, making the package
unreproducible:
ldflags := ("-Wl,-z,relro", "-Wl,-z,now",
"-Wl,--no-allow-shlib-undefined", "-Wl,--no-copy-dt-needed-entries",
"-Wl,--no-undefined");
- adaflags := ("-g", "-O2", "-ffile-prefix-map=/build/1st/adacgi-1.6=.",
"-fstack-protector-strong", "", "-gno-record-gcc-switches");
+ adaflags := ("-g", "-O2", "-ffile-prefix-map=/build/2/adacgi-1.6/2nd=.",
"-fstack-protector-strong", "", "-gno-record-gcc-switches");
soversion := "4";
A patch is attached that will modify this file just prior to
installation, but the better solution may actually belong somewhere
else in Debian's Ada toolchain. Unfortunately, I lack the knowledge
to know precisely where, but hopefully this helps demonstrate the
problem and a route to a solution.
