No.  By default libtool might build object files twice, one static and
one shared, just in case it might need both, but I disabled it ages ago
as we don't need both
(https://github.com/geany/geany/commit/723f4302e0d7bbd938c789b9730366f7c7e03080).
 Maybe check if libtool on Windows doesn't enforce something stupid like
that.

But it might also be that MSYS2 is slow or something, but that Thomas
might know more about.

Hi Nick,

Long time no hear.  I can't help with Windows build speeds but can say
that the Linux build does not appear to be significantly slower
AFAICT.

The idea behind libgeany is that it is a proper library that plugins
link against and which hides all symbols that are not specifically
exported (IIRC the way Windows always worked).  The .lo files are
object files compiled to be made part of the library.  They are, IIUC,
compiled with differing options to .o files, in particular -fPIC since
libraries may be loaded in different address locations.  I am not sure
why that would be slower to compile though.

It is possible that Geany is now compiled with different optimisations
by default, -O2 I think since that does data flow analysis that
activates a number of important warnings, but as I said the speed on
Linux is not markedly affected.


Cheers
Lex

[Geany-Devel] Building geany on Windows is slow; libgeany

2018-01-25 Thread Nick Treleaven 
Hi,
I hadn't built Geany for a while, I found the MSYS2 build instructions with
autotools. Libtool seems incredibly slow - mainly for linking but even
compiling is slow. I've tried disabling AV to no effect. Are there any
simple workarounds? The modify-rebuild cycle is painful now.

Also, I'm curious as to why .lo files are built and also interested as to
any info about libgeany.

Regards,
Nick
