需要安装 libxcb1-dev libgtk-3-dev

[czy]

安装后可以编译了，但遇到了一个断言，位于：

src/core/utils_linux.cpp line 613

我看了一下源码，这个断言是xcb_atom_t Utils::internAtom(const char *name)函数中的Q_ASSERT(connection);

xcb_atom_t Utils::internAtom(const char *name)
{
    Q_ASSERT(name);
    Q_ASSERT(*name != '\0');
    if (!name || (*name == '\0')) {
        return XCB_NONE;
    }
    xcb_connection_t * const connection = x11_connection();
    Q_ASSERT(connection);
    if (!connection) {
        return XCB_NONE;
    }
    const xcb_intern_atom_cookie_t cookie = xcb_intern_atom(connection, false, qstrlen(name), name);
    xcb_intern_atom_reply_t * const reply = xcb_intern_atom_reply(connection, cookie, nullptr);
    if (!reply) {
        return XCB_NONE;
    }
    const xcb_atom_t atom = reply->atom;
    std::free(reply);
    return atom;
}

在断言后还进行了判断，并在空的时候返回XCB_NONE，此断言是否有必要？

    xcb_connection_t * const connection = x11_connection();
    Q_ASSERT(connection);
    if (!connection) {
        return XCB_NONE;
    }

你可以暂时注释掉。此断言可能无必要，只是我不知道connection为空是否为常规现象
