我有一个连接共享(动态)库.so或.dylib从我的一个项目与另一个项目的问题。Makefile链接共享(动态)库

我使用这样的Makefile:

#libraries 
#custom 
COMPARERS_STATIC_LIB_PATH=../comparers/output/debug/lib/libcomparers.a 
COMPARERS_LIB_DIR=../comparers/output/debug/lib/ 

$(SHARED_LIBRARY): assertion.o 
    $(CC) $(CFLAGS) -L$(COMPARERS_LIB_DIR) -shared -o $(OUTPUTS_LIB_DIR)/$(SHARED_LIBRARY) $(OUTPUTS_DIR)/assertion.o -lcomparers 

$(DYNAMIC_LIBRARY): assertion.o 
    $(CC) $(CFLAGS) -L$(COMPARERS_LIB_DIR) -dynamiclib -o $(OUTPUTS_LIB_DIR)/$(DYNAMIC_LIBRARY) $(OUTPUTS_DIR)/assertion.o -lcomparers 

的目录和库到位作为下面的图片。

与静态库编译和链接链接正确:

$(TARGET): $(LIBRARY) 
    $(CC) $(CFLAGS) -o $(OUTPUTS_BIN_DIR)/$(TARGET) src/main.c $(OUTPUTS_LIB_DIR)/$(LIBRARY) $(COMPARERS_STATIC_LIB_PATH) 

的错误,我得到:

gcc -g -Wall -D__USE_FIXED_PROTOTYPES__ -std=c99 -I./include -I../comparers/include -L../comparers/output/debug/lib/ -shared -o outputs/debug/lib/libunit_tests.so outputs/debug/assertion.o -lcomparers 
ld: warning: directory not found for option '-L../comparers/output/debug/lib/' 
ld: library not found for -lcomparers 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 
make: *** [libunit_tests.so] Error 1

你有一个错字,你$(COMPARERS_LIB_DIR)包含:

../comparers/output/debug/lib/ 

但必须是:

../comparers/outputs/debug/lib/ 
       ^

涉及到你的身材。

是的,愚蠢的错误。谢谢。 –
