Is libc statically linked?
However libc has not been linked in statically, only dynamically, so it is another failed attempt.
Why is statically linking glibc discouraged?
The most important reason why glibc should not be statically linked, is that it makes extensive internal use of dlopen , to load NSS (Name Service Switch) modules and iconv conversions. The modules themselves refer to C library functions. If the main program is dynamically linked with the C library, that’s no problem.
What is glibc static?
Description: 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.
What is static and dynamic linking in C?
Static linking is the process of copying all library modules used in the program into the final executable image. Dynamic linking lets several programs use a single copy of an executable module. Static linking is performed by programs called linkers as the last step in compiling a program.
Is there a way to link libc statically?
However libc has not been linked in statically, only dynamically, so it is another failed attempt. The test program is simply the following: I’ve also tried statifier and ermine, as suggested in this question: Neither works.
Is the library libX11 linked statically or dynamically?
As you can see in the example, libX11 is not in the list of dynamically-linked libraries, as it was linked statically. Beware: An .so file is always linked dynamically, even when specified with a full filename/path.
How can I exclude a library from static linking?
Replace the dynamic library option with the full path to the static library. Rinse and repeat until you’ve processed the entire link command line. Optionally the script can also take a list of library names to exclude from static linking. The following bash script seems to do the trick:
How to not use static linking in GCC?
One solution is to put your dynamic dependencies before the –static option on the command line. Another possibility is to not use –static, but instead provide the full filename/path of the static object file (i.e. not using -l option) for statically linking in of a specific library. Example:
