--- Comment #2 from mikulas at artax dot karlin.mff.cuni.cz 2012-01-10 19:23:31 UTC --- After further testing it turns out that "make install -j8" produces the invalid Ada installation and "make install" produces a working installation. If I install the compiler with "make install -j8" (on an 8-core machine), there is a race condition: - sometimes Ada is installed correctly - sometimes, "/usr/local/gcc/lib/gcc/x86_64-unknown-linux-gnu/4.6.2/adainclude" is a file, not a directory (the file is the same as "./32/adainclude/unchdeal.ads") - sometimes "/usr/local/gcc/lib/gcc/x86_64-unknown-linux-gnu/4.6.2/adalib" is missing" So it is clearly incorrectly written install rule for Ada.
