Static Linux Builds

[anda_skoa]

When you run "configure" you can pass the install path as the "-prefix" commandline switch

And after wasting yet another 5 hours of my life, "make" stopped here:

You could check if the build has already progressed far enough for your needs.

I.e. if those libraries in Qt that your application needs have already been built.

Okay, I tried again with the "-skip qtvirtualkeyboard" parameter, and it seems like it got installed successfully this time.
Now I tried to build it as static, and that also seemed to work.

Now I only need to get it running on different Distributions (I'm using Arch Linux), those with Ubuntu and Linux Mint didn't seem to get it to run.
They get this error:

Cannot execute binary file: Exec format error

Cannot execute binary file: Exec format error

To copy to clipboard, switch view to plain text mode 

Edit:
I tried it on 2 Live Sessions (one with Linux Mint, and one with Manjaro), and on Windows 10's Ubuntu Sub System.
All 3 of them can't run my application, due to missing libraries (libwebp, libmng, etc.).
Is there something I'm missing?

[anda_skoa]

Hmm, that's a strange error

Are you perhaps building a 64-bit executable and the target systems are 32-bit?

As for the libraries, those need to be either in the system, bundled with the application (see comment #2) or statically linked.
Or Qt confgured to skip support for these formats.

And how do I statically link these 3rd party libraries?
I already got Qt-specific libraries statically linked, although I find it pointless to include, let's say, "libwebp", while the App has absolutely nothing to do with networking...

[anda_skoa]

You need the static build of those libraries.

Which is why usually no one does static linking, as it is way too much work.

This has nothing to do with networking, WebP is an image format.

Usually these are plugins but since you are doing a static build of Qt these are now built into Qt.

You can likely disable them during configure, as I said above.

Or just not statically link Qt and only ship the image plugins you need.

Well, yes...quite obvious that in order to statically linking libraries, I need to statically link libraries... （￣ー￣。）
I actually asked how I should do that.
I already tried copying stuff from "/usr/lib64", and included those libraries within the .tar.gz file I would distribute the application with, but that didn't help neither.

Similar to Qt: you get the sources for these libraries and configure and make static build.

I already tried copying stuff from "/usr/lib64", and included those libraries within the .tar.gz file I would distribute the application with, but that didn't help neither.

Make sure your start script points the LD_LIBRARY_PATH variable to the directory you've put the libraries into.

You can use "ldd" on the executable to see which libraries the runtime linker find when it tries to resolve the symbols needed by the program.
