Question

我使用的是一般的makefile，如下所示：

 public GroupChatFragment(){}
    String[] names;
    String[] presence;
    String[] available;
    String[] images;

    @Override
    protected void initView(LayoutInflater inflater) {
        super.initView(inflater);
        Resources resources = getResources();
        names = resources.getStringArray(R.array.group_names);
        presence = resources.getStringArray(R.array.users_presence);
        available = resources.getStringArray(R.array.users_available);
        images = resources.getStringArray(R.array.group_images);
    }

@Override
    protected void addDataToAdapter(SectionedRecyclerAdapter adapter) {
        for (char alphabet = 'A'; alphabet <= 'Z'; alphabet++) {
            ArrayList<Group> groups = getHeadersWithLetter(alphabet);
            if (groups.size() > 0) {
                adapter.addSection(new GroupChatSection(String.valueOf(alphabet), groups));
            }
        }
    }

private ArrayList<Group> getHeadersWithLetter(char letter) {
    ArrayList<Group> groupArrayList = new ArrayList<>();
    for (String contact : names) {
        if (contact.charAt(0) == letter) {
            Group group = new Group();
            group.setGroupName(contact);
            for (int i = 0; i < 18; i++){
                group.setAvailableUsers(available[i]);
                group.setGroupImage(images[i]);
                group.setNumUsers(presence[i]);
            }
            groupArrayList.add(group);
        }
        Collections.sort(groupArrayList, new Comparator<Group>() {
            @Override
            public int compare(final Group object1, final Group object2) {
                return object1.getGroupName().compareTo(object2.getGroupName());
            }
        });
    }
    return groupArrayList;
}

目录结构如下所有 .cpp文件包含在目录src /中，相应的头文件（ .h）文件存在于目录include /中。现在我想添加PETSc库。我该怎么做？

我明白了。如果有人在将来遇到困难，我会发布涉及PETSc的项目的通用Makefile。

include ${PETSC_DIR}/lib/petsc/conf/variables

CFLAGS += -std=c++11
