程序不會再編譯

Question

我目前正在研究C++，我在Mac上本地編輯，但在Ubuntu服務器上運行。我總是確保代碼在上傳到服務器之前在我的mac上編譯，然後在那裏編譯它，我必須使用makefile來鏈接安裝在本地目錄中的庫。基本上，我編輯了我的代碼的很大一部分，發現它編譯在我的mac上，並將它上傳到服務器進行編譯，但它不能編譯！幸運的是，我有一個備份版本的代碼，所以我在服務器上試過，並且不再編譯！在最後一次，我知道我的代碼在服務器上編譯，現在，我知道他們運行了一些更新，但這就是我所能想到的，這是不同的。作爲參考，這是我的make文件：

LOCAL_INCLUDE = /home/schraiber/.local/include 
LOCAL_LIB = /home/schraiber/.local/lib 
CXXFLAGS = -I$(LOCAL_INCLUDE) 
CXX_LDFLAGS = -L$(LOCAL_LIB) -lgsl -lm -lgslcblas -lpthread 

CoalHMMgf: main.o IOUtilities.o parameters.o Algorithms.o Optimization.o probabilities.o RNGUtilities.o Data.o ThreadData.h 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) main.o IOUtilities.o parameters.o Algorithms.o Optimization.o probabilities.o RNGUtilities.o Data.o -o CoalHMMgf 
main.o: main.cpp IOUtilities.h parameters.h Algorithms.h Optimization.h probabilities.h ThreadData.h Data.h 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c main.cpp 
IOutilities.o: IOUtilities.h IOUtilities.cpp parameters.h data.h 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c IOUtilities.cpp 
parameters.o: parameters.h parameters.cpp 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c parameters.cpp 
Algorithms.o: Algorithms.h Algorithms.cpp 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c Algorithms.cpp 
Optimization.o: Optimization.h Optimization.cpp Algorithms.h parameters.h probabilities.h RNGUtilities.h ThreadData.h IOUtilities.h 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c Optimization.cpp 
probabilities.o: probabilities.h probabilities.cpp parameters.h 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c probabilities.cpp 
RNGUtilities.o: RNGUtilities.h RNGUtilities.cpp 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c RNGUtilities.cpp 
Data.o: Data.h Data.cpp 
     g++ $(CXXFLAGS) $(CXX_LDFLAGS) -c Data.cpp 

和錯誤：

，只是驗證GSL安裝在本地目錄：

schraiber@trump:~/test_rsync$ ls ~/.local/lib 
libbpp-core.a  libbpp-core.so.2.0.0 libbpp-seq.so.9  libgslcblas.a libgslcblas.so.0  libgsl.so   pkgconfig 
libbpp-core.so libbpp-seq.a   libbpp-seq.so.9.1.0 libgslcblas.la libgslcblas.so.0.0.0 libgsl.so.0  python2.7 
libbpp-core.so.2 libbpp-seq.so   libgsl.a    libgslcblas.so libgsl.la    libgsl.so.0.16.0 
schraiber@trump:~/test_rsync$ ls ~/.local/include/ 
Bpp gsl 

一個有趣的事情需要注意的是我的程序也應該和Bpp聯繫起來，而且就我所能說的而言它確實很好。

Answer 1

您的「-lfoo」參數應該在您的「g ++」命令行中最後一個。因此，例如，在makefile中進行此更改：

CoalHMMgf: main.o IOUtilities.o parameters.o Algorithms.o Optimization.o probabilities.o RNGUtilities.o Data.o ThreadData.h 
     g++ $(CXXFLAGS) main.o IOUtilities.o parameters.o Algorithms.o Optimization.o probabilities.o RNGUtilities.o Data.o -o CoalHMMgf $(CXX_LDFLAGS) 

Answer 2

庫必須在鏈接行上定義，以便不包含其他引用的庫是最後一個。依賴於第二個庫中代碼的庫需要首先列出。它們必須在.o文件之後列出，否則假定.o文件是自包含的，並且不需要這些庫。
