Resolving Problems With Creating Reproducible Binaries Using Sun Studio Compilers

Douglas Walls, July 24, 2006

Certain flags (-g, -xipo, -xcrossfile ) invoke features of the Sun Studio Compilers and tools that must make static data global. To avoid namespace collisions, the data is globalized using a unique globalization prefix. The drawback of using a unique globalization prefix is that the resulting object files will be different every time the source file is compiled, even though the sources and compilation options are identical. So, if you compare the resulting object files from two identical compilations they will differ.
