Boost build builds in-source.

I've become quite used to building and searching etc from the source root

~/src $ b2 module
~/src $ git grep foo


This work flow has been broken because I'm not using out of source builds

~/src/build $ make module
~/src/build $ git grep... dang it! 
~/src/build $ cd ..
~/src $ git grep foo
~/src $ make modu... dang it! 
~/src $ cd build
~/src/build $ make module

I can't be the only one who wants to have the benefit of out of source 
builds and be able to build from in-source.

Will `-C` help?

~/src $ make -C build module

or in cross-platform fashion:

~/src $ cmake --build build
~/src $ cmake --build build --target foo --config Debug

I imagine it would be relatively simple to create a makefile which 
navigates to a known build directory (eg: build or debug or...), 
executes make there, and then changes directory back to where it was 
called from.


Before I do just this, I thought it better to try leverage the open 
source community - hence asking the question.


Does anyone have a script or makefile which does just this?

TIA
Steve

Make a shell function or shell script to run your build, that does the
cd to the build directory and starts the build.

Thanks for your response!

I am aware of being able to do in-source builds, but would like to continue
to reap the benefits of out-of-source builds whilst being able to build
from in-source

FYI, CMake supports in-source builds (however, particular projects may not)

[CMake] in source makefile / helper script that enables building out of source?

[Steve Lorimer]

I've recently changed over from using boost-build (
http://www.boost.org/build/) to cmake.

Boost build builds in-source.

I've become quite used to building and searching etc from the source root

~/src $ b2 module
~/src $ git grep foo


This work flow has been broken because I'm not using out of source builds

~/src/build $ make module
~/src/build $ git grep... dang it! 
~/src/build $ cd ..
~/src $ git grep foo
~/src $ make modu... dang it! 
~/src $ cd build
~/src/build $ make module

I can't be the only one who wants to have the benefit of out of source
builds and be able to build from in-source.

I imagine it would be relatively simple to create a makefile which
navigates to a known build directory (eg: build or debug or...), executes
make there, and then changes directory back to where it was called from.

Before I do just this, I thought it better to try leverage the open source
community - hence asking the question.

Does anyone have a script or makefile which does just this?
