can't use FMDB with Xcode 4

[lucaquerella]

I created a vergine project on Xcode 4, I imported FMDB (like I did with xcode 3 few months ago) just drugging the source folder, then I add libsqlite3.0.dylib on "Build Phases-> Link Binary With Libraries"

I got this error:
"ld: duplicate symbol _main in /Users/luca/Library/Developer/Xcode/DerivedData/prova4-dsulhpfwtyiffieremqmsufplmzn/Build/Intermediates/prova4.build/Debug-iphonesimulator/prova4.build/Objects-normal/i386/fmdb.o and /Users/luca/Library/Developer/Xcode/DerivedData/prova4-dsulhpfwtyiffieremqmsufplmzn/Build/Intermediates/prova4.build/Debug-iphonesimulator/prova4.build/Objects-normal/i386/main.o for architecture i386
collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1"

any suggestion? I really cannot find anything useful anywhere I really want to go on this stuff I'm doing
thank you

You imported more than you were supposed to. You only need to import FMDatabase.(h/m), FMResultSet.(h/m), and FMDatabaseAdditions.(h/m). You included "fmdb.m" as well, which is the example file showing how to use FMDB. As such, when you compiled your project, the linker found two "main()" functions: one in fmdb.m and one in main.m.

duplicate symbol _main in ...fmdb.o and ...main.o

In other words, this is your problem and not FMDB's. :)

you were completely right!
thank you very much!!

might be worth removing the example file from the src/ directory as not to confuse new users as it had me stumped too!

1.compile source checking for duplicate files
2.checked to armv7 and armv7s
3.source file
4.searchpath-framework- empty
5.organizer-leftside myproject - delate the derived data
6.include change import in all implement files
7.same name class name
8.build active architecture only change YES
9.Oter linking flags change to -force_load
10.Add to the frame work game git,quartz core,game git,core data

These all are test my app but not clear the error

ld: 7 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
