Question

嗨我在尝试使用gcc在cygwin控制台上构建poco时遇到此错误，它与配方失败有关，我不知道如何解决这个...

以下是错误代码：

$ make
make -C /cygdrive/c/poco-1.4.6p4-all/Foundation
make[1]: Entering directory '/cygdrive/c/poco-1.4.6p4-all/Foundation'

Assembler messages:

这是一堆接近第53行的代码，显示为错误：

$(OBJPATH_DEBUG_SHARED)/%.o: $(SRCDIR)/%.cpp $(DEPPATH)/%.d
    @echo "** Compiling" $< "(debug, shared)"
    $(CXX) $(INCLUDE) $(CXXFLAGS) $(DEBUGOPT_CXX) $(SHAREDOPT_CXX) -c $< -o $@

这可能很容易解决，但我几天都没有弄明白，因为我不是c ++和makefile的专家。

更新：我仍然得到相同的错误，我将添加完整的规则定义文件：

我会说问题是该目录不存在。编译器不会创建不存在的目录。在调用编译器之前，尝试修改规则以创建目录：

$(OBJPATH_DEBUG_SHARED)/%.o: $(SRCDIR)/%.cpp $(DEPPATH)/%.d
        @echo "** Compiling" $< "(debug, shared)"
        mkdir -p $(dir $@)
        $(CXX) $(INCLUDE) $(CXXFLAGS) $(DEBUGOPT_CXX) $(SHAREDOPT_CXX) -c $< -o $@
