Bug #: 12518
Summary: clang Makefile for include/clang and include/clang-c
has broken find pipeline
Product: Build scripts
Version: 3.0
Platform: PC
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P
Component: Makefiles
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Created attachment 8367
--> http://llvm.org/bugs/attachment.cgi?id=8367
The attached patch both backports trunk changes for these Makefiles to 3.0 and
adds the fixes.
The Makefiles for the clang and clang-c headers error out when using a separate
build tree because a find that won't find anything is piped into a series of
greps. grep will return 1 if it's invoked with no input (which will happen in
you're looking for include files to install in the object tree, as these only
exist in the source tree), even if it's a negative grep (-v). As this is being
used to define the list for a for loop, the simple solution is to terminate the
pipeline with "|| /usr/bin/true" so that the pipeline doesn't error out and
fail the target.
As the attached patch also backports trunk changes to 3.0, I can confirm that
this isn't resolved in the trunk.
