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

    Hi, I want to use qwt library.

    I followed the instruction at http://qwt.sourceforge.net/qwtinstall.html

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



    me@com:~/qwt-6.1.2$ make

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

    Not sure what you worry about - the build looks perfectly fine ?

    The warnings about "QtDesigner/QDesignerCustomWidgetInterface" being deprecated indicates, that Qwt uses an include path, that is going to be changed in a future version of Qt. As long as we don't have this version this not important and if it happens some day there will be an update of Qwt, with a version depending include path.

    "Nothing to be done for `first'.", means, that there is nothing to do in a directory for a specific make target ( here "first" ) - also nothing wrong with it. F.e. in the doc directory there is no build rule ( as there is nothing to build ), but there is an install rules, when calling "make install"
