I am trying to create a C++ library with QT. However, when I launch the builder, QT Creator asks me to provide an executable. I do not understand what it is really asking for. Why would need an executable to make a library?
Thanks!!!

Perhaps it is asking you for the location of "qmake"? Have you set the QTDIR and QMAKESPEC environment variables?Michael Aaron Safyan– Michael Aaron Safyan2009-09-27 09:07:27 +00:00Commented Sep 27, 2009 at 9:07

What is the executable it is asking for ? Platform details etc. will be useful as well.whatnick– whatnick2009-09-27 09:15:05 +00:00Commented Sep 27, 2009 at 9:15

The only way qtcreator ask me an executable is when I run my librairy project not when I build it. Can you tell us more about the executable it is asking for?Patrice Bernassola– Patrice Bernassola2009-09-27 09:41:09 +00:00Commented Sep 27, 2009 at 9:41

To make a static library NAME, just collect your objects into an archive with
$ ar ru libNAME.a *.o
To make a shared library, it's
$ g++ OPTIONS -shared -o libNAME.so -Wl,-soname,NAME *.o
When you are linking a shared library with g++, you also need to give it any link OPTIONS that you would need for your program if you were linking an executable. For example, extra libraries (-lm), optimisation (-O2), pthreads (-pthread) or whatever.

I guess it is trying to launch an executable (which is normal if you are developing an application).
Instead of hitting "Run" or Ctrl+R, try to use "Build" or Ctrl+B. This should prevent Qt Creator from trying to launch your project.
