[Scons-users] Randomly, Scons can not find the header

@Bill Deegan Thanks very much for your response

The command is :
"g++ -o <build path>/abc.os -I<path1> -I<path2> <build path>/abc.cpp "

In fact, the 'abc.h' and 'abc.cpp' are in the same dir, and the include way is '#include "abc.h"' using double quotation;
So, I think the compiler should just find the header file in the current dir, and the '-I' option is not used in this case, Is that right?

In addition, in your above message, what does the "proper dependencies" exactly means? Does my case above have the "proper dependencies"?

Thanks very much!

What's the command line when it fails?
Does it have the -I's?
A WAG would be that another file has the proper dependencies on the file
and thus it's getting copied to build dir, while the one(s) which fail do
not. Thus if the order of compilation changes it may not be copied in time..

Hi,
I?m using Scons 2.3 to compile our projects, but *randomly**,* scans can
{ xxx.cpp:5:37: error: xxx.h: No such file or directory }
1. One SConstruct in the root dir, and lots of SConscript in different
sub dirs
2. env.SConscript(dirs='.',exports='env',variant_dir=env[
'BUILD_DIR'],duplicate=1)
3. SetOption('duplicate','hard-soft-copy')
4. In each sub SConscript we define env: Import('env?); env = env.Clone
()
5. Also, we are using CPPPATH to search the header files
When compiling, we always clone a clean code from remote repo, so there is
no cache or something else locally.
Then the problem is, sometimes the compilation is success, sometimes it's
failure, I try to figure out the root cause and found that the header file
was not copied to 'BUILD_DIR'(duplicate=1);
I don't know why this happened, seams there is some wrong when parsing
dependency tree or cp files? I don't know.
So, do you have some ideas or suggestions for me to fix/debug this issue?
Looking forward to your response! thanks very much!!!
Thanks.

Also.. Try 3.0.1 and see if the problem goes away.
2.3 is quite old.

3.0.1

Mats,
All return values from builders are NodeLists, (list of nodes)
source=simpleclient_classes+['MANIFEST.MF'])
I've also added a link to this thread in the pull request. Hopefully Daniel
Moody will respond here.

Per the instructions still on the scons.org page, I'm emailing this here
prior to filing a ticket.
When I tried our build with 3.0.1., the CI builders for the java
versions tipped over.
15:34:53 File
"/home/jenkins-ci/workspace/iotivity-verify-linux_secured_
with_java/java/examples-java/simpleclient/SConscript",
15:34:53 example_jar = jdk_env.Jar(target='simpleclient.jar',
source=[simpleclient_classes, 'MANIFEST.MF'])
15:34:53 File
"/home/jenkins-ci/workspace/iotivity-verify-linux_secured_
with_java/scons-local/scons-local-3.0.1/SCons/Environment.py",
15:34:53 return self.method(*nargs, **kwargs)
15:34:53 File
"/home/jenkins-ci/workspace/iotivity-verify-linux_secured_
with_java/scons-local/scons-local-3.0.1/SCons/Tool/jar.py",
15:34:53 st = os.stat(path)
"""
A pseudo-Builder wrapper around the separate Jar sources{File,Dir}
Builders.
"""
simpleclient_classes = jdk_env.Java(target='classes',
source=['src/main/java'])
example_jar = jdk_env.Jar(target='simpleclient.jar',
source=[simpleclient_classes, 'MANIFEST.MF'])
(the second line is the one from the traceback)
so the return from the Java builder is passed to Jar as part of the
source list, but the new code does not appear to expect the type it is
passed as a result. It's not clear if our call to Jar is illegal, but
it worked fine through 3.0.0. It *looks* like the intent is not to do
it the way we do, since the preceding call to the Java builder seems
"Any .java files in the source list will be compiled to .class files by
calling the Java Builder. "
So it would be good to figure out if this is a new bug in jar.py, or if
the documentation should be explicit about disallowing the way we are
calling it, which at least to my reading it is not explicit about.
thanks,
-- mats

Is abc.h a generated file? Or does it exist before SCons runs?
Have you tried running with scons 3.0.1?
2.3 is pretty old and many bugs have been fixed since that was released.
