[Scons-users] Remove a macro from CPPDEFINES list

[Sisira Jayasinghe]

Converting an older build app called Cake,  similar to make with some
variations.

Yes, I have Sconscript in each folder. I wrote a csh shell script to copy
bare-bone Sconscript in each folder .

Overall there are over 30 executable and 20 or so DLLs and so's will be
created. 

 

Current plan is to have a single source root and modify env as it needs for
each app.

 

Currently compiler is invoked for each source file in a folder. Wondering if
it is faster to compile many source files with a single compiler run.

If so what would be a the best way in Scons?

 

Thank you.

Sisira

Hi Bill:

Thank you so much. It worked!

I am new to Scons and Python and working on converting a commercial CAD/CAE
software package to build on SCONS on NT and Linux. To give you an ideas I
have created over 3500 Sconscript files so far.

 

Converting from makefiles to SCons?

3500 sounds like a lot. Are you creating a SConscript per source directory?





 

So please do not be surprised to hear from me again.

 

That's what we're here for.

Please do take a read through the user guide and the manpage.

The python documentation at python.org is very good to get you the basics of
python which you'll find useful when using SCons.

 

Hope that helps!

-Bill

Hi:

The macro __STDC__ that gets defined in Sconstruct, but in certain source
folders that has to be undefined ( #undef or /U ). I cannot find an
Environment function to Remove it from CPPDEFINES list.

 

Please let me know how can I accomplish this.

 

SConstructs are just python.

env['CPPDEFINES'].remove('__STDC__') 

Should do the trick.
