xcode - Undefined symbols for architecture x86_64 when linking c project -


i try compile picoc project xcode. no external libraries, .c , .h files imported in command line tool c project.

all .c files compile without issue, when xcode linking, these messages:

    undefined symbols architecture x86_64:   "_basicioinit", referenced from:       _picocinitialise in platform.o   "_cstdout", referenced from:       _printsourcetexterrorline in platform.o       _platformvprintf in platform.o   "_mathfunctions", referenced from:       _includeinit in include.o   "_mathsetupfunc", referenced from:       _includeinit in include.o   "_picocplatformscanfile", referenced from:       _includefile in include.o   ...

the command giving error following:

/applications/xcode.app/contents/developer/toolchains/xcodedefault.xctoolchain/usr/bin/clang -v -arch x86_64 -isysroot /applications/xcode.app/contents/developer/platforms/macosx.platform/developer/sdks/macosx10.8.sdk -l/users/laurent/library/developer/xcode/deriveddata/pico-dhfwbamkhiyphjcwuncbwjsyjlax/build/products/debug -f/users/laurent/library/developer/xcode/deriveddata/pico-dhfwbamkhiyphjcwuncbwjsyjlax/build/products/debug -filelist /users/laurent/library/developer/xcode/deriveddata/pico-dhfwbamkhiyphjcwuncbwjsyjlax/build/intermediates/pico.build/debug/pico.build/objects-normal/x86_64/pico.linkfilelist -mmacosx-version-min=10.8 -o /users/laurent/library/developer/xcode/deriveddata/pico-dhfwbamkhiyphjcwuncbwjsyjlax/build/products/debug/pico

the pico.linkfilelist file contains list of necessary .o files.

unfound functions in compiled .c files (and compiled .o), should avoid these errors ? thanks.

those symbols in clibrary.c; must have missed list of source files compile.

your next question doubtless libraries link executable with, , solve suggest @ makefile.
