"Nothing to be done for `first'" message when 'make' qwt

HYKim

Hi, I want to use qwt library.

I followed the instruction at qwtinstall

But when I typed 'make', I got some error message:

I cannot understand why this result appear.
I would appreciate any kind of help.

Hi,

Those are not errors, you have warnings yes but the "nothing to be done for first" just states that make has nothing special to do in that folder.

HYKim

@SGaist Thank you for your answer.
I modified qwtconfig.pri ( Donot build QwtDesigner)

But the same error message appeared.:

This Qwt project has to make Qwt Libary as a result. But I couldn't see it.

SGaist

Again, there's no error message. "Nothing to be done" just tells you that for that precise folder, there's nothing for make to do because there's indeed nothing particular to do or everything needed was already done in a previous run.

Look in the lib folder

HYKim

@SGaist
Thank you for replying again.
But I didn't find the way to 'make' Qwt Library eventually.
So I just got it from opensource at QGroundControl's Github. It's like an expedient.
I appriciate your replies once again.

jsulm

These lines actually tell you that the library was built:

mv -f libqwt.so ../lib/ 
mv -f libqwt.so.6 ../lib/ 
mv -f libqwt.so.6.1 ../lib/

Just check lib directory.

HYKim

@jsulm Ah, I understood what you said.
libqwt.so, libqwt.so.6.1... files are the result of 'make'. Right?

SGaist

Yes, they are the qwt libraries that you want to use.

jsulm

Yes, that's QWT library you're building
