to simplify the log file the tree looks like this:
+-build::alias::openssl
+-build::alias::openssl::SDKBIN
| +-_sdks/debug_posix-x86_64_default/openssl_1.1.0_51bed083228027f76730230d116bace9/bin/c_rehash

....

| | +-[_build/build_debug_posix-x86_64/openssl/crypto/arm_arch.h]

| | | +-[_build/build_debug_posix-x86_64/openssl/Makefile]
| | +-[_build/build_debug_posix-x86_64/openssl/crypto/LPdir_nyi.c]
I am not sure why _makeinstall/openssl/bin/c_rehash -> _build/build_debug_posix-x86_64/openssl/Makefile ->_build/build_debug_posix-x86_64/openssl/crypto/buildinf.h -> _build/build_debug_posix-x86_64/openssl/Makefile
I would think c_rehash should depend on the Makefile. I would not think Scons would "know" anything about buildinf.h

copyed was me coping data to the variant directory to allow cross build to work better
log file is here https://bitbucket.org/snippets/dragon512/KeGax5
Below is the Parts file I have been hacking on ( I hope to clean it up more...) It is based on work I have yet to publish in Parts in my branch.

Jason,
I"m not aware of a Makefile scanner.
What's in variable 'copyed'?
Can you paste output of --tree=prune?

Hi,
I am setting up a build with SCons that has to build openssl. I am using the Command() logic to call the native build system. I am having an issue with this code wanting to rebuild because of a file "crypto/buildinf.h" is rebuilt as part of the process with a new date value/ This causes SCons to say stuff needs to be rebuilt. The issue here is an odd circular reference that is forming up and I am unclear on what is adding it at this time. I am hoping before I dig to deep into this that some one might know, or have some idea on what is happening. Details
I have a two commands:
out = env.Command(
["Makefile"],
copyed,
"cd ${TARGET.dir} ; ./Configure -DSSL_ALLOW_ADH enable-ec_nistp_64_gcc_128\
--prefix=${ABSPATH('#_makeinstall')}/${PART_NAME}\
--openssldir=${ABSPATH('#_makeinstall')}/${PART_NAME} linux-x86_64 shared\
"
)
Then I have a command
env.Ignore(out, ["crypto/buildinf.h"])
env.Command(
[
env.File("crypto/buildinf.h"),
"#_makeinstall/${PART_NAME}/bin/c_rehash",
...
],
["Makefile"],
[
"cd ${{SOURCE.dir}} ; make all CC=${{CC}} CXX=${{CXX}} $(-j{jobs}$)".format(jobs=env.GetOption('num_jobs')),
"cd ${SOURCE.dir} ; make install"
] )
What is happening is that after the first run Scons will tell me it needs to rebuild because:
scons: rebuilding `_build/build_debug_posix-x86_64/openssl/Makefile' because `_build/build_debug_posix-x86_64/openssl/crypto/buildinf.h' changed
I have an Ignore line that should remove this... What is odd for me is that the next build command is run because:
scons: rebuilding `_build/build_debug_posix-x86_64/openssl/crypto/buildinf.h' because `_build/build_debug_posix-x86_64/openssl/Makefile' changed
I seem to have a cycle of some kind. I am unclear on how to break it.
I am unclear on what scanner is adding this depends in Command. Do we have a generic Makefile scanner??
Any thoughts??
Jason
