Mac原生系统对ntfs格式写操作支持
弹出移动硬盘
执行 hdiutil eject /Volumes/Toshiba\ Portable\ Hard\ Drive/，如下输出
"disk1" unmounted.
"disk1" ejected.
创建一个目录，稍后将mount到这个目录
sodu mkdir /Volumes/MYHD
将移动硬盘以NTFS格式mount到上面的目录
sudo mount_ntfs -o rw,nobrowse /dev/disk1s1 /Volumes/MYHD/
执行完上面命令后，你可以看到你的移动硬盘灯又两起来了，没有任何输出，表示成功。
此时，你的移动硬盘可写了。 不过你不能在Finder里面操作，因为上面加了nobrowse选项。但是这个选项是必须的，否则你无法写。
Mac OS X 下部分Android手机无法连接adb问题之解决方案
- -----------------
- Spreadtrum phone:
- Product ID: 0x5d04
- Vendor ID: 0x1782
- ...
- Serial Number: T619
- ...
- -----------------
２. 终端进入/Users/user/.android，应该有一个adb_usb.ini文件，如果没有就创建，然后将上面的Vender ID “0x1782”单独一行加入到该文件，然后退出。
- # ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
- # USE 'android update adb' TO GENERATE.
- # 1 USB VENDOR ID PER LINE.
- 0x1782
３． 重启adb server进程。
- adb kill-server
- adb start-server
然后通过adb devices命令就可以查看到以相应设备Serial Number为名字的设备。如：
- -MacBook-Pro:.android user$ adb devices
- List of devices attached
- emulator-5554 device
- T619 device
PS：
install Python Imaging Library on mac
# download
curl -O -L http://effbot.org/media/downloads/Imaging-1.1.7.tar.gz
# extract
tar -xzf Imaging-1.1.7.tar.gz
cd Imaging-1.1.7
# build and install
ln -s /usr/local/include/freetype2 /usr/local/include/freetype
xcode-select --install
python setup.py build
sudo python setup.py install
# or install it for just you without requiring admin permissions:
# python setup.py install --user
mac 编译openresty常见问题
第一次装openresty没有事情的，然而重装MAC后，再装openresty出现了问题。安装openresty可以直接
git clone https://github.com/openresty
下来，运行make，自动下载依赖包，也可以直接到 http://openresty.org/ 下载打包好的。
1.openssl缺少错误如下
1 2 3 4 5 6 |
./configure: error: SSL modules require the OpenSSL library. You can either do not enable the modules, or install the OpenSSL library into the system, or build the OpenSSL library statically from the source with nginx by using --with-openssl=<path> option. ERROR: failed to run command: sh ./configure --prefix=/usr/local/openresty/nginx \… |
缺少openssl库，那就把本机安装路径告诉它吧:
./configure —with-openssl=/usr/local/Cellar/openssl/1.0.2c
2.openssl源码安装错误
1 2 3 4 5 6 7 8 9 10 |
/Applications/Xcode.app/Contents/Developer/usr/bin/make -f objs/Makefile cd /usr/local/Cellar/openssl/1.0.2c \ && if [ -f Makefile ]; then /Applications/Xcode.app/Contents/Developer/usr/bin/make clean; fi \ && ./config --prefix=/usr/local/Cellar/openssl/1.0.2c/.openssl no-shared no-threads \ && /Applications/Xcode.app/Contents/Developer/usr/bin/make \ && /Applications/Xcode.app/Contents/Developer/usr/bin/make install LIBDIR=lib /bin/sh: ./config: No such file or directory make[2]: *** [/usr/local/Cellar/openssl/1.0.2c/.openssl/include/openssl/ssl.h] Error 127 make[1]: *** [build] Error 2 make: *** [all] Error 2 |
上了github，https://github.com/torch/image/issues/16，查查，明白了，这里要的是source code，不是安装路径，够坑的了吧。
那么好了，到https://www.openssl.org/下载了最新的，openssl.1.0.2c版本，到bundle目录里：
export KERNEL_BITS=64./configure --with-cc-opt='-I/usr/local/Cellar/pcre/8.36/include/' \ --with-ld-opt='-L/usr/local/Cellar/pcre/8.36/lib' \ --with-openssl=bundle/openssl-OpenSSL_1_0_2c -j2
报了个warning：
1 2 3 |
WARNING! If you wish to build 64-bit library, then you have to invoke './Configure darwin64-x86_64-cc' *manually*. You have about 5 seconds to press Ctrl-C to abort. |
看着是openssl与darwin的版本不兼容问题，后来发现是新版的openssl与nginx兼容问题。
3.pcre依赖报错
1 2 3 4 5 |
ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status make[2]: *** [objs/nginx] Error 1 make[1]: *** [build] Error 2 make: *** [all] Error 2 |
找一找，发现了问题解决方案，是pcre依赖包没带上，也就是正则匹配依赖包的问题了：
在github上找到了issuse相关信息： https://github.com/openresty/ngx_openresty/issues/3#issuecomment-120227290
最后在issuse上问道了agentzh的解决方案，agentzh的makefile里在处理新版nginx与openssl依赖上的一点问题，后来他更新了github仓库：
1 2 3 4 5 6 |
export KERNEL_BITS=64 ./configure --with-cc-opt='-I/usr/local/Cellar/pcre/8.37/include/' \ --with-ld-opt='-L/usr/local/Cellar/pcre/8.37/lib' \ --with-openssl=$HOME/work/openssl-1.0.2d -j9 make -j9 sudo make install |
在我这里(MAC OSX 10.10.4)运行起来是没问题的。
两个问题：
1.openssl依赖，要用源码，要export告诉系统环境变量
2.pcre包要手动加上去。
burn an ISO on a USB drive on Mac OS X?
Directly from the Ubuntu download page (my formatting):
- Download the desired file
- Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)
- Convert the .iso file to .img using the convert option of hdiutil (e.g.,
hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso) - Note: OS X tends to put the .dmg ending on the output file automatically. Remove the .dmg extension as necessary,
mv ~/path/to/target.img{.dmg,} - Run
diskutil listto get the current list of devices - Insert your flash media
- Run
diskutil listagain and determine the device node assigned to your flash media (e.g./dev/disk2) - Run
diskutil unmountDisk /dev/diskN(replaceNwith the disk number from the last command; in the previous example,Nwould be 2) - Execute
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m(replace/path/to/downloaded.imgwith the path where the image file is located; for example,./ubuntu.imgor./ubuntu.dmg). - Using
/dev/rdiskinstead of/dev/diskmay be faster.- If you see the error
dd: Invalid number '1m', you are using GNUdd. Use the same command but replacebs=1mwithbs=1M. - If you see the error
dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive.
- If you see the error
- Run
diskutil eject /dev/diskNand remove your flash media when the command completes - Restart your Mac and hold down Alt while the Mac is restarting to choose the USB stick
Note: On newer Macs you might have to install an EFI boot manager to boot from USB.
mac上opencv安装步骤
1. 去 http://opencv.org 下载最新版OpenCV for Linux/Mac源文件，目前版本是2.4.3。下载后解压。
2. 去 http://www.cmake.org 下载最新版cmake，.dmg文件，建议使用2.8.12.2版本。下载后安装。
3. 接下来开始安装opencv(注: 如果需要启用多核支持, 可以先按第6点进行修改后再编译,未经测试)
开一个终端，进入opencv解压缩的目录，如cd 然后把文件夹拽进去。
mkdir release
cd ./release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
make
sudo make install
4. 至此opencv应该已经装上了。
注：如果cmake出现错误，请到苹果开发者网站那里下载Command Line Tools安装。（关键）
由于本人是要写python，所以还要进行下一步配置。本人mac是rmbp15，自带的python版本是2.7，终端下输入python后输入import cv，如果提示没有找到cv，请按如下步骤操作。
1. 打开一个终端，cd ~
2. vim .profile
3. 添加export PYTHONPATH=/usr/local/lib/python2.7/site-packages/，其中python2.7根据个人python版本而定。
4. source .profile
5. 至此应该全部完成了。
6.补充:
I got this working with OpenCV 2.4.10 and GCC 4.9.2. I also had to make the following additional changes to the CMakeLists.txt in the root OpenCV directory:
OCV_OPTION(WITH_OPENEXR “Include ILM support via OpenEXR” OFF)
OCV_OPTION(WITH_OPENMP “Include OpenMP support” ON)
OCV_OPTION(BUILD_OPENEXR “Build openexr from source” OFF )
I originally was running into errors with “Undefined symbols for architecture x86_64 cv::imshow, cv::imread, cv::imwrite, etc,” because Homebrew installed a clang OpenCV whereas my project was using GCC. One solution would be to rebuild everything with clang but that was not appealing in my case because I wanted OpenMP support. So I instead used your solution to build a GCC version of OpenCV.
mac下设置nat
$ sudo sysctl -w net.inet.ip.forwarding=1
$ sudo natd -interface en1
$ sudo ipfw add divert natd ip from any to any via en1Mac OSX maxfiles settings
- create or edit the file “/etc/launchd.conf”
- write in it the following: limit maxfiles 20000 50000
- run the command: sudo chmod 775 /etc/launchd.conf
- save and reboot
解决mac系统英文版本下偶尔中文文件名乱码的问题
打开Terminal
输入
echo 25:52 >~/.CFUserTextEncoding (如此诡异的解决方案)
回车
然后重启一次就好啦，这样既是英文界面，也可以看中文了！
