operating system - What is a relocatable program? - Stack Overflow
2017年4月11日 · If a program or shared library only contains position independent code it can be loaded anywhere in memory and is relocatable. Let's suppose you have a program P that is linked to shared libraries L1 and L2. If L1 and L2 require using the same location in memory, then they cannot be loaded together and P cannot run.
What is the difference between executable and relocatable in elf …
19. as you know every compiled executable file is a binary file with address relative and absolute, so relocatable format is a format in which function and other symbols still have there names definition in other word functions and variables are not bound to any specific address. Instead, the addresses are still symbols. look : unix > gcc -c ...
Difference between static library and relocatable object file?
2017年1月31日 · A static library is basically just a collection of object files. It's typically just an ar archive of object files. Using ar, you can extract object files from the library, add different object files to it, etc. Generally speaking, the difference between a dynamic library and a shared object file is the target -- Windows uses dynamic libraries ...
What is Relocatable and Absolute Machine Code? - Stack Overflow
2014年4月6日 · What gives relocatable code its major advantage and the reason why it is the most prevalent code around is that it allows code to be easily broken down into sections. Each section can be loaded anywhere in memory to fit its requirements and then during relocation, any code that references another section can be fixed-up with a relocation table ...
Can we detect "trivial relocatability" in C++17? - Stack Overflow
2019年12月20日 · The proposal talks about using an attribute to mark a type as trivially relocatable. There's no way a compiler is going to be smart enough to just look at the code and figure out if it's trivially relocatable. A programmer has to look at the implementation of, say std::unique_ptr and understand whether it is trivially relocatable. It sounds ...
virtualenv relocatable -- does it really work - Stack Overflow
I have a virtual env dir, a project dir with a req.txt. When I run pip -r req.txt, it installs some apps from github (source) and some from pypi. The ones from pypi are fine after relocatable call on the virtual evn, however the links in the site-packages for the apps that it installed from github still point to the old directory location.
linux - Why does the -r option (relocatable) make ld not find any ...
2011年7月7日 · Generate relocatable output---i.e., generate an output file that can in turn serve as input to ld. This is often called partial linking. This is often called partial linking. As a side effect, in environments that support standard Unix magic numbers, this option also sets the output file’s magic number to "OMAGIC".

2016年3月30日 · RPM spec made relocatable by adding prefix but while installing i do not see the files installed; Chapter 15. Making a Relocatable Package. A relocatable package is a package that is standard in every way, save one. The difference lies in the prefix tag. When this tag is added to a spec file, RPM will attempt to build a relocatable package.
The C++ way to relocate object of implicitly non-movable class
2020年4月22日 · So P1144 considers your type Trouble to be non-relocatable, because it is non-movable. P1144 doesn't try to introduce a new verb "relocate"; it simply provides a performant codepath for types that are already relocatable under the current standard when the operation happens to be trivial. It's impossible to make a type that is P1144-trivially ...
What does it mean for a symbol to be absolute or relocatable?
2017年2月9日 · 0. According to Assemblers And Loaders: In the case of a future symbol, the assembler does not know the type (absolute or relocatable) of the missing symbol. It thus cannot generate the relocation bit... A future symbol is a symbol encountered before it has been declared. For example: JMP TO. ... When the JMP TO instruction is assembled, the ...
