Thank you for the answer Kish. I have tried what you said and it does not work. Let me explain what I do and copy all the error message. I have created a C++ program which calls eclipse in certain iterations. Using Visual I had no problem, I just followed the Embedding manual instructions and everything was ok. Now I moved to Mac and I would like to do the same using Xcode. I have tried to import the project and I think I have followed the embedding manual instructions to configure the Xcode, however I am not sure at all because I am new using Mac. I think there is some error when linking or indicating some path or library, and I don't know if it could be any architecture problem. I installed the i386 eclipse version and I tried to compile using x86_64 and i386 obtaining the same result. The erro message is: Ld build/Debug/LR_CP_Aproach normal x86_64 cd "/Users/rbuil/Documents/Roman/Doctorat/Tesis/Xcode Program/LR_CP_Aproach" setenv MACOSX_DEPLOYMENT_TARGET 10.6 /Applications/XCode/usr/bin/g++-4.2 -arch x86_64 -isysroot /Applications/XCode/SDKs/MacOSX10.6.sdk "-L/Users/rbuil/Documents/Roman/Doctorat/Tesis/Xcode Program/LR_CP_Aproach/build/Debug" -L/Applications/Eclipse_6_0_82/lib/i386_macosx "-F/Users/rbuil/Documents/Roman/Doctorat/Tesis/Xcode Program/LR_CP_Aproach/build/Debug" -filelist "/Users/rbuil/Documents/Roman/Doctorat/Tesis/Xcode Program/LR_CP_Aproach/build/LR_CP_Aproach.build/Debug/LR_CP_Aproach.build/Objects-normal/x86_64/LR_CP_Aproach.LinkFileList" -mmacosx-version-min=10.6 -flat_namespace -o "/Users/rbuil/Documents/Roman/Doctorat/Tesis/Xcode Program/LR_CP_Aproach/build/Debug/LR_CP_Aproach" Undefined symbols: "_ec_get_long", referenced from: EC_word::is_long(long*) in CLPfunctions.o "_ec_resume1", referenced from: EC_resume() in CLPfunctions.o "_ec_cleanup", referenced from: CIterativeMethod::IterativeBucle_mixtSSG_SG(CJob*, double****)in IterativeMethod.o CIterativeMethod::IterativeBucle_SSG(CJob*, double****)in IterativeMethod.o CIterativeMethod::IterativeBucle_SG(CJob*, double****)in IterativeMethod.o "_ec_term", referenced from: term(EC_functor, EC_word, EC_word, EC_word, EC_word)in CLPfunctions.o "_ec_panic", referenced from: EC_functor::EC_functor(dict_item*)in CLPfunctions.o EC_functor::EC_functor(char*, int)in CLPfunctions.o "_ec_did", referenced from: EC_functor::EC_functor(char*, int)in CLPfunctions.o "_ec_refs_destroy", referenced from: EC_ref::~EC_ref()in CLPfunctions.o EC_refs::~EC_refs()in CLPfunctions.o "_ec_set_option_int", referenced from: CIterativeMethod::eclipseInitialization() in IterativeMethod.o CIterativeMethod::eclipseInitialization() in IterativeMethod.o "_ec_init", referenced from: CIterativeMethod::eclipseInitialization() in IterativeMethod.o "_ec_refs_create_newvars", referenced from: EC_refs::EC_refs(int)in CLPfunctions.o EC_ref::EC_ref()in CLPfunctions.o "_ec_refs_get", referenced from: EC_refs::operator[](int)in CLPfunctions.o EC_word::EC_word(EC_ref const&)in CLPfunctions.o "_ec_string", referenced from: EC_word::EC_word(char const*)in CLPfunctions.o "_ec_", referenced from: operator~(EC_word)in CLPfunctions.o "_ec_post_goal", referenced from: post_goal(EC_word) in CLPfunctions.o "_ec_long", referenced from: EC_word::EC_word(int)in CLPfunctions.o "_ec_get_double", referenced from: EC_word::is_double(double*)in CLPfunctions.o "_ec_refs_set", referenced from: EC_ref::operator=(EC_word)in CLPfunctions.o "_ec_listofrefs", referenced from: list(EC_refs&) in CLPfunctions.o ld: symbol(s) not found collect2: ld returned 1 exit status I installed the Eclipse IDE for C/C++ Developers to try to use it instead of Xcode, but I have obtained the same error message. Could anybody tell me how to fix this error? Thank you in advance.
