Compiling Qt from sources

[ODБOï]

Hi,
Thx for answer
@mrjj said in Compiling Qt from sources:

What version of mingw ?

This is not a version that comes with Qt but a separate installation of minGw, is this bad ?

mingw32-make - v
output :
GNU Make 4.2.1
Built for x86_64-w64-mingw32

I will try to :
use more recent verions
use minGw witch comes with qt tools

Thank you

Hi
Its not bad pr se, but i did burn my fingers using other version
that the one Qt provides. One issue can be 64 bit but it seems you are using 32.
so i would try the included mingw.
I know the test is not trivial due to huge compile times:)

Hi @mrjj, finally done!

But just a empty qtquick App 600Mo ?

I knew static makes the executable bigger but i was not expecting 600mo. There must be some techniques to optimise the executable size, no ?

edit : actually that was a debug build, release version is 20Mo

@mrjj meny thx for help

@LeLev
Good work :)
and yes, debug builds are amazingly fat.

@mrjj Hi,

I have a last question pls :

The folder where i installed Qt static version has now size of 638 Go ! is this 'normal' ?

[mrjj]

@LeLev
I would check where you had build folder. it most like is in that folder too.
Seems a bit big :)
So there might be tons of .o files etc remaining.

Hi
i have saved 300Go by deleting \mingw53_32_static\examples

Hi,

Always build with -nomake tests -nomake examples especially when doing a static build.
