Installed SCons using # cd scons-2.3.0 # python setup.py install
After Installation, when i try to run scons , got the below error.
scons: * No SConstruct file found. File "/usr/local/lib/scons-2.3.0/SCons/Script/Main.py", line 905, in _main
How to overcome this ???
There are 3 ways to specify the SConstruct file when using SCons, as follows:
Execute scons from the root of the project, where there should be a SConstruct file. This is the most standard way.
From a subdirectory of the project, where there should be a SConsctruct file at the root, execute scons with one of the following options (as seen by scons -h) to tell it to look up the directory structure for the SConstruct
-u, --up, --search-up Search up directory tree for SConstruct, build targets at or below current directory. -U Search up directory tree for SConstruct, build Default() targets from local SConscript.
scons -h-f FILE, --file=FILE, --makefile=FILE, --sconstruct=FILE Read FILE as the top-level SConstruct file.
Here is an example project in the directory /home/notroot/projectDir with the following directory structure:
SConstruct subdir/file.hh subdir/file.cc Here is how to use the different options mentioned above:
Option 1:
Execute scons from the root project directory
# cd /home/notroot/projectDir # scons Option 2:
Execute scons from within the project directory and tell it to look up the dir hierarchy for the SConstruct
# cd /home/notroot/projectDir/subdir # scons -u Option 3:
Execute scons from within the project directory and specify the path of the SConstruct
# cd /home/notroot/projectDir/subdir # scons -f /home/notroot/projectDir/SConstruct
