libGLESv2.dll and libEGL.dll - the libs for opengl support
They are irrelevant

try to create deployment for your program

create folder named d:\test
copy to this folder your .exe file
from cammand line: D:\Qt\Qt5.12.4\bin\windeployqt d:\test\'you_exe_file'
copy to this folder limereport.dll, QtZint.dll, libgcc_s_seh-1.dll, libstdc++-6.dll, libwinpthread-1.dll

try to lunch program
may be it's nessasary to copy some other libs, OS tell ypu about

from cammand line: D:\Qt\Qt5.12.4\bin\windeployqt d:\test\'you_exe_file'
copy to this folder limereport.dll, QtZint.dll, libgcc_s_seh-1.dll, libstdc++-6.dll, libwinpthread-1.dll

-> This is exactly what I did for environment 1: the exe takes a few seconds to launch. Not impressive but still acceptable.

If I move the exe into environment 2(our production environment) which has the same dll as environmet 1 plus other dlls, the exe takes more than 1 minutes to launch...and the harddisk is 100% taken for processing something...

It is very strange to me.

So the problem becomes much clearer now. If I put limereport-unrelated dlls in the exe directory, the launch becomes much slower.

tested the demo1/demo2 exe in release build.

now try from command line in folder d:\test
set PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;
'your_program'.exe

now try from command line in folder d:\test
set PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;
'your_program'.exe

-> gave it a try but it doesn't solve the problem.

is disc d: just a partition or separate physical disk?
may be trouble with drivers or something like this?

and.. I could build your program on my comp, but I use the mingw with SJLJ not SEH

[alexyuisme]

I realy doubt it is a physical disk issue because environemnt 1 works fine.

No need to use my program because the problem exists in demo1 too. I think you can create a deployment folder for demo1 under release build.

How to reproduce:

1. restart the machine, in the deployment folder, run LRDemo_r1.exe, time the launch time as T1.
2. restart the machine, copy some extra dlls(> 20) in the deployment folder, run LRDemo_r1.exe, time the launch time as T2.

You will notice T2 is much larger than T1.

Thanks,

BTW, what is the correct way to build static lib of limereport? I wanna give it a try.

Thanks,
Alex

[Subst]

first..
I have some projects uses LR. All of them works realy fast on my machine and others, more slower then my. On Win 10, 7 & XP.
I can't reproduce your problem
And nobody can it

Therefore I think the problem in your environments, machine or so on. On your side.
I trying to do is figure out what's going on

[alexyuisme]

That's strange. On our side, three machines have been tested and all have the same issues.

Alex

[Subst]

I agree it's so strange

it's especially strange because it work fine from QtCreator, as you said

[Subst]

well
can you send me your test project with all libs exists in folder?

[alexyuisme]

Sure. I have prepared two environments.

env1 : https://github.com/alexyuisme/test_limereport/blob/master/env1.zip

env2: https://github.com/alexyuisme/test_limereport/blob/master/env2.zip.001
      https://github.com/alexyuisme/test_limereport/blob/master/env2.zip.002
      https://github.com/alexyuisme/test_limereport/blob/master/env2.zip.003
      https://github.com/alexyuisme/test_limereport/blob/master/env2.zip.004
      https://github.com/alexyuisme/test_limereport/blob/master/env2.zip.005

After unzip, click LRDemo_r1.exe.

Thanks,
Alex

[Subst]

well
look this video

it's so fast I think, less then 0.5 sec

alexyuisme, what antivirus are you using?
try to temporary disable it and lunch program
