[Scons-users] SCons always rebuilds on Windows

[Dirk Heinrichs]

Hi,

When trying a simple Java build on Windows 7, SCons (2.3.0) always rebuilds 
unconditionally:

C:\Users\dhs\scons_test>scons -Q

scons: warning: No version of Visual Studio compiler found - C/C++ compilers 
most likely not set correctly
File "C:\Users\dhs\scons_test\SConstruct", line 2, in <module>
C:/jdks/1.7/jdk/bin/javac.exe -d classes -sourcepath src src\Hello.java

C:\Users\dhs\scons_test>scons -Q

scons: warning: No version of Visual Studio compiler found - C/C++ compilers 
most likely not set correctly
File "C:\Users\dhs\scons_test\SConstruct", line 2, in <module>
C:/jdks/1.7/jdk/bin/javac.exe -d classes -sourcepath src src\Hello.java

If I rebuild again, adding --debug=explain, I get this:

C:\Users\dhs\scons_test>scons -Q --debug=explain

scons: warning: No version of Visual Studio compiler found - C/C++ compilers 
most likely not set correctly
File "C:\Users\dhs\scons_test\SConstruct", line 2, in <module>
scons: Cannot explain why `classes\Hello.class' is being rebuilt: No previous 
build information found
C:/jdks/1.7/jdk/bin/javac.exe -d classes -sourcepath src src\Hello.java

               4 Verzeichnis(se), 211.825.582.080 Bytes frei

If I run the same build on Linux, it works as expected:

% scons -Q
/usr/bin/javac -d classes -sourcepath src src/Hello.java
% scons -Q
scons: `.' is up to date.

Anything I can do to solve the problem?

Thanks...

	Dirk
