[Scons-users] 回复: Scons-users Digest, Vol 144, Issue 8

Mon Sep 25 06:23:09 EDT 2023

Hi Guys,

	I find that if I set -j8, the printing messages sequence will be disordered.
	I think the reason is python print buffer has competition in multithreading. Am I right?
	And how can I resolve it.

Best Regards!

Should be fairly easy.
Just change your build string to have
-o ${TARGET.dir}
instead of
-o $TARGET

If this is for non-shared object C file the variable in question would be CCCOM.

One caveat, this assumes the generated file is still going to be /Debug/Obj/main.o from your initial example, and not named something else.
Scons keeps track of the target files and if what a build step generates doesn't match what's expected you will see unnecessary rebuilds.

Hi Guys?

	I find the wat to remove defalut target from Object function.
	Rplace the Environment CCCOM, CCCOM can set compiler command line.
	For example:
		env.Replace(CCCOM = '$CC $SOURCES -o $TARGET')
		then, the command line will contain the $TARGET
		if I set env.Replace(CCCOM = '$CC $SOURCES -o $TARGETPATH')
		then, the command line will use $TARGETPATH instead of $TARGET. Of course, I need to set Environment TARGETPATH.

Best Regards!

Hi Guys,

????I am trying to use Scons with IAR, IAR is a embedded IDE.
????For iccarm(IAR compiler), It's unnecessary to set target name, I just set the directory of object file.
????For example,
???????iccarm.exe -o /Debug/Obj   /Src/main.c
????But if I don't set target file name, Scons will set default target file directory and name which base on the source file.
????I want to use iccarm method that set the target directory only, and remove default object file name from Object function.
????How can I do it.

????Thanks!

Best Regards!

This concept is roughly the same as "batch" building, which is only explicitly supported right now for the Microsoft compiler - you can see a note here:

https://scons.org/doc/production/HTML/scons-man.html#cv-MSVC_BATCH

It's not that this hasn't come up before (see, for example:
https://github.com/SCons/scons/issues/1923), but the work to expand this to other places hasn't been contributed yet.  Not sure which tool you're using to run iccarm, so it's hard to advise further at this point.
