- Subject: [PATCH] Fix Ada makefile problem with parallel make
Hello,
when bootstrapping with parallel make and Ada enabled, I'd regularly
get errors like "xnmake: Text file busy", because two Makefile rules
that might run in parallel both create and use the xnmake binary.
This patch adds a quick fix to serialize those two rules to avoid
that problem.
Bootstrapped/regtested on s390-ibm-linux and s390x-ibm-linux.
OK?
ChangeLog:
* ada/Make-lang.in (ada/nmake.ads): Add dependency on ada/nmake.adb
to force serialization.
