Make: Nothing to be done for 'first'

[andreyc]

You are welcome.
Try to rebuild a project.
Do you use QtCreator ?
What messages do you see in "Compile Output"?
You can switch to "Compile Output" using Alt-4 (if you did not change default shortcuts).

Really thank u sir! yes, i use qtcreator under mac, the message of "Compile Output" is here, lots of warning..so I delete them, just post the final information.

[andreyc EDIT] Added @ around log messages

[andreyc]

It says that you successfully built the project and show have SimpleNGL executable in a build directory.
Do you see any error messages in "Application Output"(Alt-3) panel when you try to run it?

[alex111]

Thanks for your reply again, really thank u vert much, there is some message about the code itself, I mean some option about what the code will do, not error message, I work under a red hat system now, is it available to send u the code and let u have a look? in the "Application output", the final line said: ........exited with code 0

You can create a simple example that does not work the same way as your project and post it here.
Or put an archive somewhere and post a link here.

Thanks u again, sir! here is a link , u can click the download tag on the top right side. Thanks for spending your time to give this help!!

This is not Qt application. it is XWindow application.
I don't have all necessary libraries to build it.
Maybe if you run SimpleNG from command line you will see some logging and error messages.

[alex111]

Thanks for your reply again, sir! I try to run it in Terminal, same like the situation in qtcreator..... no idea to fix it.....

[andreyc]

Could you post here how did you run it and what did you get. Just copy-past from a terminal.

[alex111]

Tanks for your reply again sir! really thanks! In the terminal. I use "make clean" first, and then use q make, and make.(some warning like yesterday) Then use ./XXX, it runs, the message is same like before, in the "application output". Sorry for my rubbish skill, just a fish .
After make, the message is :
g++ -Wl,-O1 -Wl,-rpath,/opt/qtsdk/5.1.0/gcc_64 -Wl,-rpath,/opt/qtsdk/5.1.0/gcc_64/lib -o SimpleNGL args.o argsgraph.o graph.o main.o maxflow.o -L/opt/qtsdk//5.1.0/gcc_64/lib -lQt5Gui -lQt5Core -lGL -lpthread
after ./XXX, no response.
All seems the same like yesterday.

Looks like you have application problem and need to debug it.
Or maybe some required libraries are not installed.
Try to run it under debugger.

[alex111]

Thanks again and again, Sir! I use debug option(F5), there is no message come out in the debugger window, it means sth wrong?

You need to run debugger is step mode.
Put breakpoint on function main() then use F5 to start debugger and use F10 to step through the code.

hello alex. I am getting the same problem that is "make: Nothing to be done for 'first'". did you solve it finally? some persons advised to run in debug mode. it doesn't run in debug mode. only thing happens is run and after that showing this same message again and again. I tried using different version of QT but same error shows up.

[jsulm]

@biswasp said in Make: Nothing to be done for 'first':

"make: Nothing to be done for 'first'"

This isn't a problem. As already said in this thread it means that the project is already built and up to date. If you app doesn't start then you have another problem. Build your app in Debug mode and then try to start it with debugger pressing F5. Maybe it simply crashes or some DLLs are missing.
