Re: [Seqan-dev] Precompiled header

[Jongkyu Kim <xenigmax@gmail.com>]

Hi Yue Gan!

I can make precompiled header without any problem. (g++ 4.9.2, Debian)

Would you give me more information about your environment? (eg. gcc / OS versions)

Best,

Jongkyu

Hi Yue,

sorry for the late reply. I have not yet tried precompiling the header and I
am not sure how it would work at all with strongly templatized code → how
would the compiler know which instantiations you actually use later on?
Although other sources claim its possible:
https://bytes.com/topic/net/answers/438738-should-templates-included-pch-files

Do other people have experience with this?

Something else you can do to speed up the build with SeqAn when using gcc is
passing -flto=N where N is the number of your cores, possibly +1. This
parallelizes most parts of the build even for a single translation unit.
