问题 I am trying to build a Library to use in an application. I built the library as below, and when i compile the application i get the below error: I have done the beolw things. I use: gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) In Library to be called from application: Here i have lot of modules, but entry point to this library is func() (i.e., main () is replaced with func() so that i can call the module, also func () is not declared as 'static'.) In one of files: int func (); ... int

Why is statically linking glibc discouraged?

问题 Most of the sources online state that you can statically link glibc, but discourage from doing so; e.g. centos package repo: The glibc-static package contains the C library static libraries for -static linking. You don't need these, unless you link statically, which is highly discouraged. These sources rarely (or never) say why that would be a bad idea. 回答1: The reasons given in other answers are correct, but they are not the most important reason. The most important reason why glibc should

What happens to static variables when libraries are statically linked

不羁的心 提交于 2020-07-17 08:27:51
问题 Let's say I have library (A) implementing the singleton pattern (it has a static variable in its implementation). (A) library is compiled as a static library. Now, let's say I have in my probject: (B) , another static library linking statically with (A) . (C) , another static library linking statically with (A) . (D) , a top level program linking with (B) and (C) . In the end, is my singleton really a singleton (and my variable really static)? Are (B) and (C) seing the same static variable
