How does one manage shared libraries (*. So) during Linux running? In Linux, the search and loading of shared libraries are implemented by/lib/lD. So. LD. So searches for the shared libraries used by applications in the standard channels (/lib,/usr/lib. However, how can lD. So find the shared library that needs to be used in non-standard channels? Currently, a co

The GCC/LD compilation link has many potential rules. If you are not aware of this hidden rule, it will take a long time to debug it. the following summarizes some of the potential rules I have encountered. This article is the first release, and other potential rules will be released one after another. Potential rules: When a symbol appears in multiple target files (. O) at the same time, LD reports an erro

Today, we have understood the usage of LD used by Vivi, And the meanings of common options are also clear. After looking at the link script of the kernel, we found that it was quite complicated, and we had to have a good grasp of the global situation. We must also be clear about the allocation of the entire address space. This cannot be done for the time being. It is a follow-up job. First, let's summarize the basic usage of

Before learning about the functions of files in the/etc/lD. So. conf. d/directory, we will first introduce several methods for running programs to load dynamic libraries:First, run the ldconfig commandThe ldconfig command is mainly used in the default search directory (/lib and/usr/lib) and dynamic library configuration file/etc/lD. so. search for the shared dynamic link library (Format: lib *. so *) to cre

There are many ways to calculate the similarity between two strings.AlgorithmTo calculate the similarity. Levenshtein distance (LD): LD may measure the similarity between two strings. Their distance is the addition, deletion, and modification of values during the conversion of a string into that string. Example: If str1 = "test", str2 = "test", then LD (str

We compile each C or assembly file separately, but do not connect, generate a lot of. o Files, These. o files are first scattered, the first thing we need to consider is how to combine them, and secondly, these. o files have a mutual invocation relationship; Moreover, the last bin file we generate is to be run in hardware, and each part of the address must be carefully explained. I think in writing makefile, the most important thing is LD's understanding, the following talk about my experience:F

Binutils error. When using gcc-O to connect to the target file, the following error occurs:/usr/local/bin/ld: This linker was not configured to use sysrootscollect2: LD returned 1 exit status. The following error is reported: C compiler cannot create executables. This may be because there is another version of GNU linker lD that does not match in your/usr/local

Scenario: A series of errors occurred while running the program, such: (1) The following error occurs when compiling the kernel and executing the make menuconfig command: /Usr/local/bin/ld: cannot load LD backend library 'libld _ elf_x86_64.so ':Libld_elf_x86_64.so: cannot open shared object file: no such file or directory That is /Usr/local/bin/ld: cannot load

Problem: There is a requirement in work: you need to make some judgments and substitutions in LD script using macro definitions like C-Define.Experiment:1: Theoretically *.c can be used, whether GCC/LD also support the direct use of the macro in LD script, the result:Arm-linux-ld:xxx.lds:2: Ignoring invalid character ' # ' in Expressionarm-linux-ld:xxx.lds:2: syn

The recent work with the compiler tool may be the result of an accumulation of problems in the concentration outbreak.Today, Ld-linux.so.x has a lot of interest, want to know more about it, so Baidu. The command LDD was found.About LDDIn fact, LDD is a script, not a binary file.The principle is simple: when the environment variable ld_trace_loaded_objects is not empty, only the dependencies are displayed, and the program is not executed.

LD_LIBRARY_PATH Linux environment variable name. This environment variable is mainly used to specify other paths except the default path for finding a shared library (dynamic link library. (This path is located before the default path)Some specific dynamic libraries are often used when Porting Programs, and these compiled dynamic libraries are placed in our own directories. In this case, you can set these directories to LD_LIBRARY_PATH. When the execution function is dynamically linked. so, if t
