Re: Using Emacs with Autotools projects : separate source and binaries directories

MyProject/src
MyProject/bin
MyProject/bin/linux
MyProject/bin/windows

configure.ac:
AC_CONFIG_SRCDIR(src/main.cpp)
No VPATH customization.

Compilation:
~MyProject : cd bin/linux
~MyProject : ../../configure
~MyProject : make

In fact, when I am reading the generated Makefiles, VPATH variables
are correctly set.

I see the problem right now, but I don't understand it. And I really
don't know how to solve it !

In fact, I have the next source tree:
MyProject/src/
MyProject/src/libcore
MyProject/src/plugins
MyProject/src/tests

If I have an error in MyProject/src/libcore and I am running make in
MyProject/bin/linux/src/libcore, source code is correctly found.
If I have an error in MyProject/src/plugins and I am running make in
MyProject/bin/linux/src/plugins, source code is correctly found.
Same for the test directory.

But, I have an error in MyProject/src/libcore and I am running make in
MyProject/bin/linux/src, source code is not found anymore.
This is weird and unpractical.

Do you anderstand this behaviour ?


I have a little more question about Emacs configuration.
When I was building binaries in the source directory, I was running
'make' in the directory of the current file.
It was simple.

Since Makefiles have moved, I am running 'make' in src directory.
Is it a good idea ?


Thanks in advance.

Best regards.
