c++ - gcc auto dependency full path -

-

i have simple project - has foo.cxx , bar.h:

// bar.h // nothing  // foo.cxx #include "bar.h" // nothing else

if include bar.h ""s, dependency file has full paths:

$ g++ -std=c++11 -mp -mmd -mf /home/barry/sandbox/foo.d        -c /home/barry/sandbox/foo.cxx -o /home/barry/sandbox/foo.o  $ cat foo.d /home/barry/sandbox/foo.o: /home/barry/sandbox/foo.cxx \  /home/barry/sandbox/bar.h  /home/barry/sandbox/bar.h:

however, if include <>s , add -i., bar.h itself:

$ g++ -std=c++11 -i. -mp -mmd -mf /home/barry/sandbox/foo.d        -c /home/barry/sandbox/foo.cxx -o /home/barry/sandbox/foo.o  $ cat foo.d /home/barry/sandbox/foo.o: /home/barry/sandbox/foo.cxx bar.h  bar.h:

is there way full paths all of files?

the issue -i. when gcc determining include <bar.h>, find ./bar.h, , printed in dependency file in same way.

if provide full path via -i well:

$ g++ -std=c++11 -i/home/barry/sandbox -mp -mmd        -mf /home/barry/sandbox/foo.d        -c /home/barry/sandbox/foo.cxx        -o /home/barry/sandbox/foo.o

then regardless of "" or <>, full path of bar.h in foo.d, desired.
