SCons
- SCons Wiki Frontpage
- Single HTML Manpage
- SCons Construction Variables om bvb de compiler te specifiëren.
Opsplitsen SConstruct en SConscript
Waarom? http://www.scons.org/doc/2.1.0/HTML/scons-user/c3356.html
Build output definiëren, duplicate source files, etc. Voorbeeld SConstruct
file:
SConscript('SConscript', variant_dir######'build', duplicate0)
Voorbeeld file om Google Test mee te (proberen) builden SConscript
:
def Glob( pattern ###### '*.*', dir '.' ):
import os, fnmatch
files = []
for file in os.listdir( Dir(dir).srcnode().abspath ):
if fnmatch.fnmatch(file, pattern) :
files.append( os.path.join( dir, file ) )
return files
# construction variables: http://www.scons.org/doc/0.96.90/HTML/scons-user/a3061.html

Poging tot converteren van deze voorbeeld Makefile
- supplied bij de gtest sources:
# A sample Makefile for building Google Test and using it in user
# tests. Please tweak it to suit your environment and project. You
# may want to move it to your project's root directory.
#
# SYNOPSIS:
#
# make [all] - makes everything.
# make TARGET - makes the given target.
# make clean - removes all files generated by make.
# Please tweak the following variable definitions as needed by your
# project, except GTEST_HEADERS, which you can use in your own targets
# but shouldn't modify.
# Points to the root of Google Test, relative to where this file is.
# Remember to tweak this if you move this file.
GTEST_DIR = ..
# Where to find user code.
USER_DIR = ../samples
# Flags passed to the preprocessor.
# Set Google Test's header directory as a system directory, such that
# the compiler doesn't generate warnings in Google Test headers.
CPPFLAGS += -isystem $(GTEST_DIR)/include
# Flags passed to the C++ compiler.
CXXFLAGS += -g -Wall -Wextra -pthread
# All tests produced by this Makefile. Remember to add new tests you
# created to the list.
TESTS = sample1_unittest
# All Google Test headers. Usually you shouldn't change this
# definition.
GTEST_HEADERS = $(GTEST_DIR)/include/gtest/*.h <br/>
$(GTEST_DIR)/include/gtest/internal/*.h
# House-keeping build targets.
all : $(TESTS)
clean :
rm -f $(TESTS) gtest.a gtest_main.a *.o
# Builds gtest.a and gtest_main.a.
# Usually you shouldn't tweak such internal variables, indicated by a
# trailing _.
GTEST_SRCS_ = $(GTEST_DIR)/src/*.cc $(GTEST_DIR)/src/*.h $(GTEST_HEADERS)
# For simplicity and to avoid depending on Google Test's
# implementation details, the dependencies specified below are
# conservative and not optimized. This is fine as Google Test
# compiles fast and for ordinary users its source rarely changes.
