invalid_ compiler, should break the build

(1/1)

oBFusCATed:
It turned out that if you have an invali_d compiler and then try to debug something, there is no error message shown as it should.
I'm talking about the debugger's branch of course.

I've debugged it a bit and the reason is that the exit code from the compiler is not set to != 0.
I've tried this patch and it works:

Is it OK, to commit it? (The m_LastExitCode is going to be committed in trunk).

p.s. Morten can you add me to an exclude list, so I can post about invalid __ compilers?

killerbot:
what exactly will this mean. Something that should NOT break are the following use cases. A project with several targets, each building with a different compiler. It is well possible that sometimes certain compilers are not installed. Then a build 'all' (aka every target) should not fail, because some compiler is missing.
This is just for compiling/linking, not for launching the debugger off course.

oBFusCATed:
Two corrections to the patch:

The "m_LastExitCode = 0;" part is needed, because if I have two target project and I try to build a failing target, then switch to the correct target and try to launch the debugger, it thinks that the build failed.

killerbot: You case seems to work and I think the reason is that the invalid_compiler message is printed at the beginning of the build, so if there is something that modifies the m_LastExitCode after I've set it, everything is OK.
Also m_LastExitCode it not used inside the compiler, it is meant for the outside world:)

If it doesn't break other builds (i.e. building C::B) go ahead.

Not possible, sorry. That's a kind of "global search & replace) independent of users. The same would happen to me and even Yiannis.

...but I saw you find a work-around... ;-)
