[Scons-users] placing object files to one common directory

[Endre Bak]

Hi,

" There isn't a good reason to copy objects around IMHO." Placing .o files
into the source directory is an ugly thing. And I don't want to copy
objects around, I want the compiler to place the .o files directly into the
object directory.

The VariantDir() function doesn't seem to be working at all:

GTEST_DIR = '../GTestGMock/gtest-1.7.0'

for objDir, srcDir in [('gtest', GTEST_DIR + '/src'), ('mock', 'mock'),
('', 'src')]:
    print 'objs/{} <- {}'.format(objDir, srcDir)
    VariantDir('objs/' + objDir, srcDir, duplicate=0)

env = Environment()
env.Append(CXXFLAGS = '-g -Wall -Wextra -pthread -isystem
{}/include'.format(GTEST_DIR))

env.StaticLibrary('output/gtest', [GTEST_DIR + '/src/gtest-all.cc'],
CPPPATH=[GTEST_DIR, GTEST_DIR + '/include'])

Output:

$ scons
scons: Reading SConscript files ...
objs/gtest <- ../GTestGMock/gtest-1.7.0/src
objs/mock <- mock
objs/ <- src
scons: done reading SConscript files.
scons: Building targets ...
g++ -o /home/endre/Prg/Repos/GTestGMock/gtest-1.7.0/src/gtest-all.o -c -g
-Wall -Wextra -pthread -isystem ../GTestGMock/gtest-1.7.0/include
-I/home/endre/Prg/Repos/GTestGMock/gtest-1.7.0
-I/home/endre/Prg/Repos/GTestGMock/gtest-1.7.0/include
/home/endre/Prg/Repos/GTestGMock/gtest-1.7.0/src/gtest-all.cc
ar rc output/libgtest.a
/home/endre/Prg/Repos/GTestGMock/gtest-1.7.0/src/gtest-all.o
ranlib output/libgtest.a
scons: done building targets.

It is requested that the objects compiled from
*../GTestGMock/gtest-1.7.0/src* should be placed into *objs/gtest* but it
is placed into the source directory instead.

Regards,
Endre
