Hello all, I'm trying to compile a program I have written and tested using ROOT. I am using g++ to compile. I first tried modifying the Makefile provided by the ROOT team, but I get the error messages: Makefile:32: *** missing separator. Stop. So, I tried using just the command: g++ Platforms.cxx but I get many undefined references, though I've included all the proper libraries. Here are the errors: /tmp/cc8ouf7p.o(.text+0x42): undefined reference to `TFile::TFile(char const *, char const *, char const *, int)' /tmp/cc8ouf7p.o(.text+0x60): undefined reference to `TObject::operator delete(void *)' /tmp/cc8ouf7p.o(.text+0xe5): undefined reference to `TObject::operator delete(void *)' /tmp/cc8ouf7p.o: In function `ReadChamber(char const *, TTree *)': /tmp/cc8ouf7p.o(.text+0x16f): undefined reference to `TObject::operator delete(void *)' /tmp/cc8ouf7p.o(.text+0x34c): undefined reference to `Form(char const *,...)' /tmp/cc8ouf7p.o(.text+0x6ff): undefined reference to `TObject::operator delete(void *)' /tmp/cc8ouf7p.o: In function `__static_initialization_and_destruction_0': /tmp/cc8ouf7p.o(.text+0xe22): undefined reference to `ROOT::GenerateInitInstance(Chamber const *)' /tmp/cc8ouf7p.o(.text+0xe2d): undefined reference to `ROOT::TGenericClassInfo::SetImplFile(char const *, int)' /tmp/cc8ouf7p.o: In function `TObject::operator new(unsigned int)': /tmp/cc8ouf7p.o(.gnu.linkonce.t.__nw__7TObjectUi+0xe): undefined reference to `TStorage::ObjectAlloc(unsigned int)' /tmp/cc8ouf7p.o: In function `Chamber::Chamber(void)': /tmp/cc8ouf7p.o(.Chamber::gnu.linkonce.t.(void)+0x10): undefined reference to `TObject::TObject(void)' /tmp/cc8ouf7p.o(.Chamber::gnu.linkonce.t.(void)+0x1d): undefined reference to `Chamber virtual table' I am attaching the Makefile, and below are my include statements. Please help me understand how to compile code that uses ROOT libraries.
