不过，我会推荐 GCC，并且我确实建议使用最新版本的 GCC。例如，最近出现了 GCC 4.6.2，并且最近在 GCC 中投入了大量工作来提高其针对 ARM 处理器的性能。因此，如果可能的话，我们使用 4.6 GCC，而不是 4.3 GCC（某些硬件供应商不会在其 ARM 开发套件中提供最新的 GCC；在这种情况下，您应该考虑从其源代码构建您的 GCC（也许还有 binutils）。
我对GPS本身一无所知。
I don't think that the compiler matters that much. What is more important is your precise understanding of the library you are using, or of the actual device you are invoking.
However, I will recommend GCC, and I do recommend using a very recent version of GCC. For instance, GCC 4.6.2 is appearing these days, and there have been lot of work recently put in GCC to improve its perfomance for ARM processors. So, if possible, us a 4.6 GCC, not a 4.3 one (some hardware vendors don't give recent GCC with their ARM development kit; you should consider in that case building your GCC (and perhaps binutils) from their source code.

我认为编译器没有那么重要。更重要的是您对所使用的库或所调用的实际设备的准确理解。

I know nothing about GPS itself.
