# SCons
|
||
|
|
||
|
1. [SCons Wiki Frontpage](http://www.scons.org/wiki/FrontPage)
|
||
|
2. [Single HTML Manpage](http://www.scons.org/doc/HTML/scons-man.html#lbAF)
|
||
|
3. [SCons Construction Variables](http://www.scons.org/doc/0.96.90/HTML/scons-user/a3061.html) 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:
|
||
|
|
||
|
```python
|
||
|
SConscript('SConscript', variant_dir######'build', duplicate0)
|
||
|
```
|
||
|
|
||
|
Voorbeeld file om Google Test mee te (proberen) builden `SConscript`:
|
||
|
|
||
|
```python
|
||
|
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

env ###### Environment(CXX 'g++',
|
||
|
CPPPATH = '../:./include')
|
||
|
|
||
|
# add to library search path env.Append(LIBPATH = ['/usr/local/lib/'])
|
||
|
# add to libraries link path env.Append(LIBS = ['SDL_image','GL'])
|

env.Append(CPPFLAGS = ['-isystem ./include'])
|
||

env.Append(CXXFLAGS = ['-g', '-Wall', '-Wextra', '-pthread'])
|
||
|
|
||
|
env.SharedLibrary(target ###### 'gtest_main.dll', source ['../src/gtest-all.cc'])
|
||
|
|
||
|
# after that, we should link with gtest_main
|
||
|
```
|
||
|
|

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.
