One *simple* Release build of fetchmore

andre

Perhaps you are right, and I misunderstood.

Regarding the distribution question, I think that considering the quality level that can be reached with software developed with a platform like Qt-Creator, is not a bad think consider also a good setup to distribute the application and don't simply deliver a exe file.

Regarding the license, it's true, but after reading and reading and reading ... all the options for licensing the software, I decided that the LGPL license is probably the best solution because you can delivery already LGPL licensed libraries, your software and yours of third party components with this license or not.

I agree with Andre, building statically is not the simple solution. For those that are on the market by a sufficient number of year, I hope they remember what great wonderful revolution was when dynamic libraries was introduced in the development world.

What I meant with the fact that the code grows, was not only a mere problem of dimensions, but also of how the program work, I think that the performances slows with big programs respect to a package.

Concluding, I am experiencing a problem delivering applications developed with Qt for desktop. Is there the right way to find exactly ALL the components needed to deliver a program with libraries ?

Hi,

I also prefer using the libraries, you only need to deliver them once for many binaries.
But to find all needed libraries? On windows I suggest using DependencyViewer. That's what I do.

Alicemirror

Gerolf,

my problem is there. I use DependencyViewer too, but there is a case that I continue to have a problem with (seems silly, but is still unresolved) jpeg images...

giesbert

If you us eplug-ins, it's something you must know. These are loaded during runtime with LoadLibrary, which is not found be dependencyViewer, sorry. This is something, that's up to you and I klnow no tool, that helps with it :-(

Alicemirror

Thank you very much for this advice. Now, the question is forked ;)

How I know if I - unconsciouscly use the eplug-ins? I was sure the there was "something" I was using in develop mode and I missed when was in the application...
Why e-plugins are note clearly evidentiated ? It's an obvious thing that I miss for ignorance or what ?

Thank again.

Please note that static linking has implications on the licensing of your software.

LGPL does AFAIK require dynamic linking to be applicable. So by linking statically against a non-commercial Qt you will need to use the GPL licensing option if I understood the licenses correctly, which will then apply to your code as well. I am not a lawyer though.

I agree, this is a confirmation on what I told in a previous post.

I user LGPL due for two important things: can be delivered with public and non-public components / libraries and is possible to create LPGL and Proprietary licenses at the same time. So, considering that - this is my point of view - dynamic linking is more flexible than static - I agree this licensing method.

andre

In principle, I think you could use static linking under LGPL if you provide a means to link against a new/modified version of the libs. That is possible, if you provide the object files. Opinions on this matter differ though, and I don't know of any court rulings on the matter.

Alicemirror

Andre, thank you, this is new for me. I am not a lawyer, but for other reasons me and my wife read a lot about open-source, copyleft and open licensing.
I never though to include object for future re-linking of updates in all-in-one application. But this means almost to include also the essential for the compiler / linker. And what about when the versions of the compiler / linker are updated ? This method seems to complicate the things...

The compile output follows, and I don't know what "command failed with exit code 1 [and 2]" means. Thank you for any assistance that you can provide:

And would it be normal for this routine to add an 's' to fetchmore before the '.exe' like it did on "/OUT:release\fetchmores.exe @C:\Users\Admin\AppData\Local\Temp\fetchmores.exe.5572.1732.jom"?
