Thread: Good compiler

Never happens to me. Could it be that code you are removing is not exactly the same as code you put back?

If something like this is happening - have you tried "rebuild all" before doing your trick?

Are you using "Precompiled headers"? I never use them. Seems to me they make more harm than help.

I also mostly avoid "Build and Continue" feature of MSVC.

So if you are using them - I suggest to try to disable them and see if problem persists.

Recent versions of Microsoft Visual Studio come bundled with pretty good compilers. Case of getting what you pay for. While gcc is pretty good, but recent versions don't stand up well when compared objectively with a number of recent commercial products - including Microsoft's. [Although compiler and other developer products have historically leap-frogged each other, so I wouldn't exclude the possibility of gcc jumping ahead in future].

I'm with vart on turning off precompiled headers and suspecting the code you add is not what you removed. I never use precompiled headers for similar reasons, with any compiler. Precompiled headers have their uses but, in practice, I have rarely found benefits exceed the problems.

Clang is not bad compiler either and produces very helpful messages. You can grab it from https://sourceforge.net/projects/min...g-3.2-release/.

@vart
It is the same code, I use Ctrl+C (copy) and Ctrl+V (paste). I am using precompiled header (I don't like using them, but I couldn't find where to turn them off).

Often such problems are caused by you changing files during the build, or occasionally by cancelling the build at just the right moment.
If it is the same code, then there are plenty of other ways to force the file to be recompiled. Right-click "recompile", or rebuild project, etc.

What version of Visual Studio are you using?

There are many objective and subjective measures by which compilers can be compared - compliance with a particular standard is only one of them. gcc support of C++11 (according to the gcc site) is experimental (which typically means "use at own risk") whereas Visual Studio support of C++11 - according to Microsoft - is incomplete. I'm not going to buy into a debate about whether experimental support of a language is better or worse than incomplete support.

However, to answer your question, one area where modern versions of gcc fall down somewhat is in quality of code generated. Not that they are bad (I would argue that few modern compilers are really bad) but recent versions of Microsoft compilers are measurably better, in terms of amount of code generated, performance of that code, and memory usage.

Can you tell me which gcc-dw2-4.6* package I need to download to get it to work on Windows 7 32-bit?

My internet is slow; I would like to avoid downloading the wrong ones in trial and error.

Download MinGW-w64 - for 32 and 64 bit Windows from SourceForge.net

Got no answer, I tried i686-w64-mingw32-gcc-dw2-4.6.3-2-release-win32_rubenvb.7z and it appears to work.
At least "Hello World" worked with C++.
