boost::spirit compilation time

[Marcin Kalicinski]

Hi All,

Does anybody has experience compiling XML parser written with boost::spirit
on gcc? The parser is based on
http://spirit.sourceforge.net/reposi...ations/xml.zip samples.

What I'm concerned of is compilation time - my current version takes about
30 minutes to compile on gcc 3.4.2 - this is completely unaccteptable. Am I
doing something wrong or is this expected with gcc? N.b. on MSVC 2005 it
compiles in less than 1 minute.

cheers,
Marcin

I use boost::spirit for my precompiler and the compile time for it is
horrible. However, the created executable is lightning fast.

HTH,

Are you using mingw/g++? I'm fairly certain the mingw/g++ doesn't
support PCH, which may be the reason VC is so much faster. However, I
don't know if boost::spirit is using PCH or not, it's just one idea that
sprang to mind.

I find that VC is generally faster than g++ on Windows. Smaller
executables, too.

Of course 30 minutes vs 1 minute seems to be quite a difference. You are
talking about YOUR code and not the library, right?

No precompiled header will help you here. It's the grammer what makes a
compiler crawl.

yup, I can confirm that. However, once you compile, your code will be
fast (well optimized) and light (no libraries needed).
