This tutorial shows how to use the SSH Host Aliases feature to quickly change the target machine of several VisualGDB projects. This feature allows switching a set of Linux projects to a different remote machine without manually editing each of them and is available in Custom and Ultimate editions of VisualGDB.<\/p>\n

    \n
  1. We will start with creating a normal Linux project using the Linux Project wizard:\"01-newprj\"<\/a><\/li>\n
  2. The first project we create will be a normal application:\"02-prjtype\"<\/a><\/li>\n
  3. The next wizard page normally allows selecting a specific remote machine. However this time instead of hardcoding a machine name and user name, select “Create a new global alias”:\"03-alias\"<\/a><\/li>\n
  4. Define an arbitrary name for your alias and point it to your existing machine connection:\"04-newalias\"<\/a><\/li>\n
  5. Proceed with the default file transfer settings:\"08-alias\"<\/a><\/li>\n
  6. Now we will create another project in the same solution. Right-click on the solution in Solution Explorer and select “Add->New Project”:\"06-newprj\"<\/a><\/li>\n
  7. This time, select “Static Library” as the project type:\"07-lib\"<\/a><\/li>\n
  8. Now the host selection page will list the alias we have previously created. Select this alias, press “next” and proceed with the default source access settings:\"08-alias\"<\/a><\/li>\n
  9. Ensure you add the newly created library to the dependencies of the application project via Build Dependencies -> Project Dependencies:\"09-deps\"<\/a><\/li>\n
  10. Replace the library source file to have a function returning the current host name:\"10-gethostname\"<\/a><\/li>\n
  11. Modify the main source file to call that function and build your solution:\"11-build\"<\/a><\/li>\n
  12. Set a breakpoint after the ‘cout’ line and start debugging. Verify that the correct host name is shown in the output window:\"12-print\"<\/a><\/li>\n
  13. Now we will switch both projects to a different target machine by changing the target of our global alias. Select Tools->SSH Host Manager, go to the Host Aliases page and change the target for the alias you created before:\"13-hostmgr\"<\/a>If you have not made a connection to that machine before, you can add it on the first page of the SSH Connection Manager.<\/li>\n
  14. Hit F5 to build and debug both the application and the library again. You will see that they both are now built and launched on a different machine:\"14-newhost\"<\/a><\/li>\n<\/ol>\n

    The host aliases affect all VisualGDB projects for a given user and are stored in the following file:<\/p>\n
