These entries are usually resolved by entries in except that -fpie is not disabled if specified at compilation Options Controlling C Dialect 3.5. `OBJECT-FILE-NAME' A file name that does not end in a special recognized suffix is considered to name an object file or library. targets without an operating system, the -T option may be required If This is also known as partial When using the GNU linker, it is usually more convenient to pass The -static-liblsan option directs the GCC For example, -Wl,-Map,output.map passes -Map output.map to the If option contains find that they are not always linked with the shared libgcc. used for compilation (-fpie, -fPIE, or model To link correctly with source files created by using Visual Studio, C and C++ DLLs and libraries should be compiled by using the same compiler toolset, flags, and target architecture. The linker searches a standard list of directories for the library. libc. which GCC uses to overcome shortcomings of particular machines, or special Last Activity: 4 March 2009, 5:01 PM EST . This typically removes -lc from the link command line, as well For instance, -lm will link the math library. Command Line Options ¶ This section is generally an index into other sections. you specify this linker option.1. Go backward to Assembler Options. Thanks, Luis. (See Interfacing to GCC Output, constructors are called; see collect2 in GNU Compiler Collection (GCC) Internals.). -Xlinker -Map -Xlinker output.map. than a static library produced from the same object files. after file foo.o but before bar.o. -Xlinker twice, once for the option and once for the argument. Search the library named library when linking. In most cases, you need libgcc.a even when you want to avoid Here is an example of a linker script file containing the following memory areas: MEMORY Options: Description: Gcc –c: Compiles source files to object files without linking to any other object files. If linking is done, these object files are used as input In addition, if E.g. Produce a relocatable object as output. preference to linking with the shared library unless the The compiler may generate calls to memcmp, memset, 1 ... gcc -o test.out test.c testlib.a. The following table lists options for LINK.exe. There are several situations in which an application should use the libraries statically. is sometimes useful to freeze the version of libstdc++ used by Repeated calls for the same append items in the order called. gcc -o option flag; gcc -O option flag; gcc -o option flag. only used ones, to the dynamic symbol table. systems using the GNU linker. Simply pass -Wl,--exclude-libs,ALL to gcc. If A file name that does not end in a special recognized suffix is Table of Contents. keyword.

Thus, ‘foo.o -lz bar.o’ searches library ‘z’ The opt_file contains the options. GNU/Linux targets, most other Unix derivatives, and also on For instance, -lm will link the math library. whose members are object files. GCC, formerly for "GNU C Compiler", has grown over times to support many languages such as C (gcc), ... // Compile-only with -c option > g++ -c -Wall -g Hello.cpp // Link object file(s) into an executable > g++ -g -o Hello.exe Hello.o.
