Bug 301727 – dev-util/ccache breaks -MD option

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Mariusz Kozlowski 2010-01-21 15:57:34 UTC]

That breaks dependencies when the makefile runs with its current directory
different from its object directory - for instance glibc does this.


Reproducible: Always

Steps to Reproduce:
1. mkdir testxyz
2. touch foo.c
3. gcc foo.c -c -o `pwd`/foo.o -MD
   foo.d will say:
   /this/directory/foo.o: foo.c
4. ccache gcc foo.c -c -o `pwd`/foo.o -MD
   foo.d will say:
   foo.o: foo.c

Actual Results:  
If you use -MD

'*.d' files are in source folder


Expected Results:  
If you use -MD

'*.d' files should be in target (binaries) folder


This is exactly the same problem as reported here in debian bus:

Also my bug report is almost all copy and paste from debian report. It is the same issue and I verified the wrong behaviour.

Hmm ... I believe this is the patch for fixing this issue:

ive pushed the issue upstream (among all the other outstanding Gentoo patches)

[Comment 3 SpanKY 2010-04-11 21:31:39 UTC]

fix should be included with ccache-3.0

[Comment 4 SpanKY 2010-11-19 09:46:12 UTC]

ccache-3.1.1 in the tree which should fix this
