Undefining linker symbols in gcc -

Undefining linker symbols in gcc -

We have a program that runs on embedded OS. We usually embed a version string in the output binary that can identify all versions while generating binary. Normally the compiler used by us can ensure that the version string is created in "binary" by making the "undefined" symbol, which is resolved by our version string.

However, now we have a Linux based system and GCC.

GCC is removing the version string from the last version. The last CEE has been built through linking to a group of libraries. Each library has a version string embedded.

The GCC version is removing the string because nothing is referring to the string and we have turned on-on optimization.

Is there any way to make sure that GCC does not snap the collection of strings (about 5-10 versions of the strings need to be embedded in us)?

Thank you.

OK, to solve this, we did this in the ac file:

   const char_string_ [] = "some string";    Then include an object file in the final link:  
  GCC & lt; snip & Gt; -Wl, - start-group string.o  gt; -well, - end-group-wl, - strip-all -o final.exe

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
