How to configure QT6 static?

hsjeong

HI, I am a new beginner of QT6.
What i want to do is to make an application using QT6 and then deploy it to an embedded linux device which is not going to install QT6 source inside.

I searched some documents and I found that I had to build my QT6 source by static to deploy my application stand alone.

Then, I was following this video;
youtube.com/watch?v=2qsR8Dw8uzA

AND
i was trying to use
$ make -j8
command
then, i was stuck with this error message.
$ make: *** No targets specified and no makefile found. Stop.

What would be the problem?
My log is like this;

Note: Using static linking will disable the use of dynamically loaded plugins. Make sure to import all needed static plugins, or compile needed modules into the library.
Note: Hunspell in Qt Virtual Keyboard is not enabled. Spelling correction will not be available.

@hsjeong you have probably put the makefile somewhere else (with -prefix or something else). Or, since it is Qt 6, perhaps the build system is ninja, not make. Hard to say without seeing the actual configuration line you have used.

TomZ

@hsjeong a couple of things;

there is no need to compile statically as long as you simply deploy the generated dynamic libraries to your device.
you most likely need to cross-compile to the architecture of your embedded device. Are you sure it is running the same CPU as the one you compile with?
Building for: linux-g++ (x86_64, CPU features: mmx sse sse2)
compiling as static means things like image plugins (jpeg/png etc) support is going to be missing. Are you sure you want to compile statically?
