make error

[peace_comp]

Hi..
While I was compilin' my project ..I had the following msg error when I used make to compile :

mingw32-make -f Makefile.Debug
mingw32-make[1]: Entering directory 'C:....'
mingw32-make[1]:Nothing to be done for 'first'
mingw32-make[1]:Leaving directory

???
I used qmake -project to generat the .pro and make to generate the makefile

..
if some one could help
Thx

Make says the project is already built.

These aren't error messages. make just tells you that there's nothing to do. Either everything is already compiled or your Makefile is incomplete. Did you remember to run qmake again to generate Makefile from .pro file?

I dont understand ..i was compiling all the time ..everythg was alright .. since I had used some q Sql class ..then I had a msg error Sql4.dll not found.. after that most of my applications wont be compiled with the make command.. givin me the same msg !!???

When you already have a project file, you MUSN'T call "qmake -project" because it will overwrite the project file with a file generated using simple heuristics. Those heuristics work fine when there are no intermediate files (so without first compilation), but get confused when some trash resides in any of the subdirectories or the current directory.

then I had a msg error Sql4.dll not found..

Next time you encounter such error, edit your .pro file, add "QT += sql" and run qmake without any parameters.
