I'm making a C program for school, when I open my file in Dev-C++ 4 and compile it works perfectly, but when I open it with the 5 beta, I this:

Building Makefile: "C:\WINDOWS\Desktop\Makefile.win"
Executing  make...
make.exe -f "C:\WINDOWS\Desktop\Makefile.win" all
gcc.exe -c School\ stuff/squares.c -o School\ stuff/squares.o -I"C:\DEV-CPP\include" -ansi -traditional-cpp -w -fexceptions -fshort-double -fverbose-asm -lobjc -pg -g3 -O3 -fexpensive-optimizations

gcc.exe School\ stuff/squares.o  -o "test.exe" -L"C:\DEV-CPP\lib"  -I"C:\DEV-CPP\include" -ansi -traditional-cpp -w -fexceptions -fshort-double -fverbose-asm -lobjc -pg -g3 -O3 -fexpensive-optimizations

Execution terminated
Compilation successful

Then when I try to run it, it says, "Project is not compiled"
And the size of the compiled file is -1074183156 bytes, can anyone help me???
