Bug ID: 44444
Summary: Lacking support of output directory when compiling
multiple source file
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs

Even though clang supports multiple source files as input, it does not allow
specifying an output directory, where to locate the generated object files,
meaning it forces the user to put it in current directory.
For example, in case of building a project that consists of 3 source files:
1.cpp, 2.cpp, 3.cpp, and wishing to put the generated object file in a specific
directory, forces you the call each clang process individually with its source
and output file name:
- clang.exe -g -o ".\myproj\debug\1.obj" 1.cpp
- clang.exe -g -o ".\myproj\debug\2.obj" 2.cpp
- clang.exe -g -o ".\myproj\debug\3.obj" 3.cpp
A better solution (in my humble opinion) is to call clang once, with all input
files, specifying the directory where to save the output files:
- clang.exe -g -o ".\myproj\debug" 1.cpp 2.cpp 3.cpp
I'm aware that under Linux everything is considered as file, therefor
specifying output directory might be mistakenly considered as an output file,
but i'm sure there's a good way to workaround that.
