ext4文件系统中自带的debug信息如何查看？

ext4文件系统代码中自带有用于调试的debug语句，如函数ext4_map_blocks中的 ``` ext_debug("ext4_map_blocks(): inode %lu, flag %d, max_blocks %u," "logical block %lu\n", inode->i_ino, flags, map->m_len, (unsigned long) map->m_lblk); ``` 请问如何使得这种语句生效？多谢

关于富士通单片机C语言编程宏定义的问题

1.main头文件中定义了 EXT_GLOBAL宏做条件编译 #define EXT_GLOBAL 2.global文件中的条件编译 #ifdef EXT_GLOBAL #define GLOBAL_EXT #else #define GLOBAL_EXT extern #endif 又定义了一个宏GLOBAL_EXT GLOBAL_EXT __direct BitType LED; #define b0_LED LED.Bits.BIT0 #define b1_LED LED.Bits.BIT1 #define b2_LED LED.Bits.BIT2 #define b3_LED LED.Bits.BIT3 #define b4_LED LED.Bits.BIT4 #define b5_LED LED.Bits.BIT5 #define b6_LED LED.Bits.BIT6 #define b7_LED LED.Bits.BIT7 GLOBAL_EXT __direct BitType LED0; //数码管 GLOBAL_EXT __direct BitType LED1; //数码管 GLOBAL_EXT __direct BitType LED2; //风速条 GLOBAL_EXT __direct BitType LED3; 这个GLOBAL_EXT __direct BitType LED;是什么意思？这个什么语句？用的是富士通的698K单片机。 GLOBAL_EXT void Delay( unsigned char dly ); GLOBAL_EXT void mcuInit( void ); GLOBAL_EXT void timerCal( void ); GLOBAL_EXT void dispFreah( void ); GLOBAL_EXT void ledOff( void ); GLOBAL_EXT void IndoorCommR( void ); GLOBAL_EXT void IndoorCommT( void ); GLOBAL_EXT void key( void ); GLOBAL_EXT void varaInit( void ); 还有这些函数在宏的后边是什么用？网上我已经找了好几遍了，也看书再找，没找到这些语句的作用，麻烦大神给解答一下

 rvm 安装 ruby 报这样的错，怎么整啊，大神来帮帮我，一天了都没搞好 "/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- rubygems/core_ext/kernel_warn (LoadError)"

make_ext4fs打包system.img后能刷入，但开机定屏

Linux 1、原厂线刷包提取：system.img 2、simg2img system.img system_raw.img 3、mkdir system 4、mount -t ext4 -o loop system_raw.img system 5、......修改system/app/....（不会是这一步的问题） 6、make_ext4fs -l 512M -s -a system system_new.img system 7、打包后的system.img替换原厂线刷包里的system.img 问题一：能正常刷入手机，但刷完后手机不开机，在开机画面定住不动，求助，这到底是为什么呀？ 问题二：上述第6步中的512M这个参数怎么确认？我这里的512是按挂载后system文件夹的大小，不知道正确不？

linux ext4 格式问题，求高手帮忙，急……

打包成ext4格式是包如下错，测试需要打包的文件内容几十M时，不出错。 猜想是Linux默认配置参数的问题，百度，Google没找到答案。高手帮忙解决下，急…… ./mkuserimg.sh -s serverlog system7.img.ext4 ext4 1190M in mkuserimg.sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.8.0_05/bin:/opt/tomcat/code/airpushData/apktools/linux:/root/bin ./make_ext4fs -s -l 128M -a 1190M system7.img.ext4 serverlog Creating filesystem with parameters: Size: 134217728 Block size: 4096 Blocks per group: 32768 Inodes per group: 8192 Inode size: 256 Journal blocks: 1024 Label: Blocks: 32768 Block groups: 1 Reserved block group size: 7 error: do_inode_allocate_extents: Failed to allocate 64758 blocks

用C语言编译完成这个程序，但我现在在学Java，对C的了解不多，希望大触们能帮帮我

 批量数据插入CODE表 解析code.csv文件批量插入CODE[PFPN]） 插入DB时，做简单检查：主键(前三个栏位)中任何栏位不允许为空，不符合条件的节点不处理，但需要记录不符合条件的记录的总数，在返回结果中体现。 出现重复记录时不要报错而是更新，最终返回结果需要返回更新和插入的记录条数。 这是数据库表的基本结构，前三个栏位是主键 INSERT INTO cms.ccode (CODE_CATE, CODE, CODE_EXT, SUBITEM, CODE_DSC, EXT_1, EXT_2, EXT_3, EXT_4, EXT_5) VALUES('PFPN', '0002', 'P101TCAWA0Z', 'P101CCAW70Z', '10.1', '1410901-A1', 'N1011', 'C101NWT3', 'P101TCAWA1', 'M01');

CM4 NVIC优先级的问题

  CM4的资料就给这么点说明，也百度过好多贴子，不明白该怎么操作，才能设置不同的优先级，还有就是怎么分主优先级和子优先级。 我理解是往NVIC->IP里写一个值（值是范围是0~7）,值越大，该优先级就越小，不知道对不对 我所参考的源代码是MQX4.1的代码，文件名为nvic.c ``` /*! * \brief Initialize a specific interrupt in the cortex core nvic * * \param[in] irq Interrupt number * \param[in] prior Interrupt priority * \param[in] enable enable the interrupt now? * * \return uint32_t MQX_OK or error code */ _mqx_uint _nvic_int_init ( // [IN] Interrupt number _mqx_uint irq, // [IN] Interrupt priority _mqx_uint prior, // [IN] enable the interrupt now? bool enable ) { VCORTEX_NVIC_STRUCT_PTR nvic = (VCORTEX_NVIC_STRUCT_PTR)&(((CORTEX_SCS_STRUCT_PTR)CORTEX_PRI_PERIPH_IN_BASE)->NVIC); _mqx_uint ext_irq_no = irq - 16; // check priority value, must be below maximal enabled/set value if (prior >= (1 << CORTEX_PRIOR_IMPL)) { return MQX_INVALID_PARAMETER; } if (irq >= PSP_INT_FIRST_INTERNAL && irq <= PSP_INT_LAST_INTERNAL) { nvic->PRIORITY[ext_irq_no >> 2] = (nvic->PRIORITY[ext_irq_no >> 2] & ~(0xff << ((ext_irq_no & 3) * 8))) | (((prior << CORTEX_PRIOR_SHIFT) & CORTEX_PRIOR_MASK) << ((ext_irq_no & 3) * 8)); if (enable) _nvic_int_enable(irq); else _nvic_int_disable(irq); } else return MQX_INVALID_PARAMETER; return MQX_OK; } /*! * \brief Enable interrupt on cortex core NVIC * * \param[in] irq Interrupt number * * \return uint32_t MQX_OK or error code */ _mqx_uint _nvic_int_enable ( // [IN] Interrupt number _mqx_uint irq ) { VCORTEX_NVIC_STRUCT_PTR nvic = (VCORTEX_NVIC_STRUCT_PTR)&(((CORTEX_SCS_STRUCT_PTR)CORTEX_PRI_PERIPH_IN_BASE)->NVIC); uint32_t ext_irq_no = irq - 16; if (ext_irq_no >= PSP_INT_FIRST_INTERNAL && ext_irq_no <= PSP_INT_LAST_INTERNAL) { nvic->ENABLE[ext_irq_no >> 5] = 1 << (ext_irq_no & 0x1f); } else return MQX_INVALID_PARAMETER; return MQX_OK; } /*! * \brief Disable interrupt on cortex core NVIC * * \param[in] irq Interrupt number * * \return uint32_t MQX_OK or error code */ _mqx_uint _nvic_int_disable ( // [IN] Interrupt number _mqx_uint irq ) { VCORTEX_NVIC_STRUCT_PTR nvic = (VCORTEX_NVIC_STRUCT_PTR)&(((CORTEX_SCS_STRUCT_PTR)CORTEX_PRI_PERIPH_IN_BASE)->NVIC); uint32_t ext_irq_no = irq - 16; if (ext_irq_no >= PSP_INT_FIRST_INTERNAL && ext_irq_no <= PSP_INT_LAST_INTERNAL) { nvic->DISABLE[ext_irq_no >> 5] = 1 << (ext_irq_no & 0x1f); } else return MQX_INVALID_PARAMETER; return MQX_OK; } ``` ``` ```

Java学习的正确打开方式

在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员必须掌握的核心算法有哪些？

由于我之前一直强调数据结构以及算法学习的重要性，所以就有一些读者经常问我，数据结构与算法应该要学习到哪个程度呢？，说实话，这个问题我不知道要怎么回答你，主要取决于你想学习到哪些程度，不过针对这个问题，我稍微总结一下我学过的算法知识点，以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的，并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构，当然，我也会整理一些看过

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。 那么，怎么保证自己的薪酬安全呢？ 我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
