Reading out version of cc1plus (SCons script-based)

Question

Actually I'm trying to read out the version of my cc1plus executable in windows. This is a rather simple job: cc1plus -version

I need this for a scons script (Tool), to integrate an ARM cross compiler. Because of that I directly call cc1plus instead of using some compiler driver. There is no useful compiler driver available.

Back to my problem: When I'm calling "cc1plus -version" on cmd I get a version string back, but cc1plus isn't terminated. Instead it is continuously executed. I have to kill cc1plus with CRTL+D. For my script this is a problem.

In the following a snippet of my cmd:

C:\DevTools\CrossWorks_for_ARM_2.3\bin>cc1plus -version

GNU C++ (GCC) version 4.7.3 20121207 (release) [ARM/embedded-4_7-branch revision 194305] (arm-unknown-eabi) compiled by GNU C version 3.4.4 (mingw special), GMP version 4.3.2, MPFR version 2.4.2, MPC version 0.8.1 GGC heuristics: --param ggc-min-expand=100 --param ggc-min-heapsize=131072

^C

C:\DevTools\CrossWorks_for_ARM_2.3\bin>

Is there any trick to terminate cc1plus after retrieving the version? For me it is rather incomprehensible why cc1plus isn't terminating.

Exactly! But I also tried it directly via cmd. The behaviour (not terminating) is the same. — ferraith, Jun 06 '13 at 16:18

You might want to give it something to compile. Maybe be redirecting input from null: (not sure if that's correct for windows). Though if so, that looks like a moderately strange compiler

Thanks for your hint! This works: `cc1plus -quit -version NUL`. I expected the version is printed on stdout, but cc1plus prints it on stderr. This was another issue. – ferraith Jun 06 '13 at 17:00
