Link, typically invoked as ``go tool link'', reads the Go archive or object
for a package main, along with its dependencies, and combines them
into an executable binary.
Command Line
Usage:
go tool link [flags] main.a
Flags:
-B note
Add an ELF_NT_GNU_BUILD_ID note when using ELF.
The value should start with 0x and be an even number of hex digits.
-D address
Set data segment address.
-E entry
Set entry symbol name.
-H type
Set executable format type.
The default format is inferred from GOOS and GOARCH.
On Windows, -H windowsgui writes a "GUI binary" instead of a "console binary."
-I interpreter
Set the ELF dynamic linker to use.
-L dir1 -L dir2
Search for imported packages in dir1, dir2, etc,
after consulting $GOROOT/pkg/$GOOS_$GOARCH.
-R quantum
Set address rounding quantum.
-T address
Set text segment address.
-V
Print linker version and exit.
-X importpath.name=value
Set the value of the string variable in importpath named name to value.
This is only effective if the variable is declared in the source code either uninitialized
or initialized to a constant string expression. -X will not work if the initializer makes
a function call or refers to other variables.
Note that before Go 1.5 this option took two separate arguments.
-a
Disassemble output.
-asan
Link with C/C++ address sanitizer support.
-buildid id
Record id as Go toolchain build id.
-buildmode mode
Set build mode (default exe).
-c
Dump call graphs.
-compressdwarf
Compress DWARF if possible (default true).
-cpuprofile file
Write CPU profile to file.
-d
Disable generation of dynamic executables.
The emitted code is the same in either case; the option
controls only whether a dynamic header is included.
The dynamic header is on by default, even without any
references to dynamic libraries, because many common
system tools now assume the presence of the header.
-debugtramp int
Debug trampolines.
-dumpdep
Dump symbol dependency graph.
-extar ar
Set the external archive program (default "ar").
Used only for -buildmode=c-archive.
-extld linker
Set the external linker (default "clang" or "gcc").
-extldflags flags
Set space-separated flags to pass to the external linker.
-f
Ignore version mismatch in the linked archives.
-g
Disable Go package data checks.
-importcfg file
Read import configuration from file.
In the file, set packagefile, packageshlib to specify import resolution.
-installsuffix suffix
Look for packages in $GOROOT/pkg/$GOOS_$GOARCH_suffix
instead of $GOROOT/pkg/$GOOS_$GOARCH.
-k symbol
Set field tracking symbol. Use this flag when GOEXPERIMENT=fieldtrack is set.
-libgcc file
Set name of compiler support library.
This is only used in internal link mode.
If not set, default value comes from running the compiler,
which may be set by the -extld option.
Set to "none" to use no support library.
-linkmode mode
Set link mode (internal, external, auto).
This sets the linking mode as described in cmd/cgo/doc.go.
-linkshared
Link against installed Go shared libraries (experimental).
-memprofile file
Write memory profile to file.
-memprofilerate rate
Set runtime.MemProfileRate to rate.
-msan
Link with C/C++ memory sanitizer support.
-n
Dump symbol table.
-o file
Write output to file (default a.out, or a.out.exe on Windows).
-pluginpath path
The path name used to prefix exported plugin symbols.
-r dir1:dir2:...
Set the ELF dynamic linker search path.
-race
Link with race detection libraries.
-s
Omit the symbol table and debug information.
-shared
Generated shared object (implies -linkmode external; experimental).
-tmpdir dir
Write temporary files to dir.
Temporary files are only used in external linking mode.
-u
Reject unsafe packages.
-v
Print trace of linker operations.
-w
Omit the DWARF symbol table.
