# Zig GNU C Library ("glibc") Support
Zig supports building binaries that will dynamically link against the
[GNU C Library ("glibc")](https://www.gnu.org/software/libc/) when run.
This support extends across a range of glibc versions.
By default, Zig binaries will not depend on any external C library, but
they can be linked against one with the `-lc` option. The target ABI defines
which C library: `musl` for the [musl C library](https://musl.libc.org/) or
`gnu` for the GNU C library.
A specific GNU C library version can be chosen with an appropriate
`-target`. For example, `-target native-native-gnu.2.19` will use the
default CPU and OS targets, but will link in a run-time dependency on
glibc v2.19 (or later). Use `zig env` to show the default target and
version.
Glibc symbols are defined in the `std.c.` namespace in Zig, though the
`std.os.` namespace is generally what should be used to access C-library
APIs in Zig code (it is defined depending on the linked C library).
See `src/glibc.zig` for how Zig will build the glibc components. The
generated shared object files are sufficient only for compile-time
linking. They are stub libraries that only indicate that which symbols
will be present at run-time, along with their type and size. The symbols
do not reference an actual implementation.
## Targets
The GNU C Library supports a very wide set of platforms and architectures.
The current Zig support for glibc only includes Linux.
Zig supports glibc versions back to v2.17 (2012) as the Zig standard
library depends on symbols that were introduced in 2.17.
## Glibc stubs
The file `lib/libc/glibc/abilist` is a Zig-specific binary blob that
defines the supported glibc versions and the set of symbols each version
must define. See https://github.com/ziglang/glibc-abi-tool for the
tooling to generate this blob. The code in `glibc.zig` parses the abilist
to build version-specific stub libraries on demand.
The generated stub library is used for compile-time linking, with the
expectation that at run-time the real glibc library will provide the
actual symbol implementations.
### Public Headers
The glibc headers are in `lib/libc/include/generic-glibc/`. These are
customized and have a couple Zig-specific `#ifdef`s to make the single set
of headers represent any of the supported glibc versions. There are
currently a handful of patches to these headers to represent new features
(e.g. `reallocarray`) or changes in implementation (e.g., the `stat()`
family of functions).
The related Zig https://github.com/ziglang/universal-headers is a project
designed to more robustly build multi-version header files suitable for
compilation across a variety of target C library versions.
## Glibc static C-Runtime object files and libraries
Linking against glibc also implies linking against several, generally
"invisible" glibc C Runtime libraries: `crti.o`, `crtn.o`, `Scrt1.o` and
`libc_nonshared.a`. These objects are linked into generated Zig binaries
and are not run-time linking dependencies. Generally they provide
bootstrapping, initialization, and mapping of un-versioned public APIs to
glibc-private versioned APIs.
Like the public headers, these files contain a couple customiziations for
Zig to be able to build for any supported glibc version. E.g., for glibc
versions before v2.32, `libc_nonshared.a` contained stubs that directed
the `fstat()` call to a versioned `__fxstat()` call.
These files used for these objects are in `lib/libc/glibc`. See the
`tools/update_glibc.zig` tool for updating content in here from the
upstream glibc.
# More Information
See
https://github.com/ziglang/zig/commit/2314051acaad37dd5630dd7eca08571d620d6496
for an example commit that updates glibc (to v2.38).

particular OS or coordinated development effort within which the
ELF header's e_machine value plus (for dynamically linked programs)
the PT_INTERP dynamic linker name and DT_NEEDED shared library
names fully identify the runtime environment required by an

Linux community) use note type 1 and a vendor name string of "GNU"
for a note descriptor that indicates ABI requirements. The note data
is four 32-bit words. The first of these is an operating system
number (0=Linux, 1=Hurd, 2=Solaris, ...) and the remaining three
identify the earliest release of that OS that supports this ABI.

/* The following macros are used for PLT bypassing within libc.so
(and if needed other libraries similarly).
First of all, you need to have the function prototyped somewhere,
say in foo/foo.h:
int foo (int __bar);
If calls to foo within libc.so should always go to foo defined in libc.so,
then in include/foo.h you add:
libc_hidden_proto (foo)
line and after the foo function definition:
int foo (int __bar)
{
return __bar;
}
libc_hidden_def (foo)
or
int foo (int __bar)
{
return __bar;
}
libc_hidden_weak (foo)
Similarly for global data. If references to foo within libc.so should
always go to foo defined in libc.so, then in include/foo.h you add:
libc_hidden_proto (foo)
line and after foo's definition:
int foo = INITIAL_FOO_VALUE;
libc_hidden_data_def (foo)
or
int foo = INITIAL_FOO_VALUE;
libc_hidden_data_weak (foo)
If foo is normally just an alias (strong or weak) to some other function,
you should use the normal strong_alias first, then add libc_hidden_def
or libc_hidden_weak:
int baz (int __bar)
{
return __bar;
}
strong_alias (baz, foo)
libc_hidden_weak (foo)
If the function should be internal to multiple objects, say ld.so and
libc.so, the best way is to use:
#if IS_IN (libc) || IS_IN (rtld)
hidden_proto (foo)
#endif
in include/foo.h and the normal macros at all function definitions
depending on what DSO they belong to.
If versioned_symbol macro is used to define foo,
libc_hidden_ver macro should be used, as in:
int __real_foo (int __bar)
{
return __bar;
}
versioned_symbol (libc, __real_foo, foo, GLIBC_2_1);

/* The following macros are used for indirect function symbols in libc.so.
First of all, you need to have the function prototyped somewhere,
say in foo.h:
int foo (int __bar);
If you have an implementation for foo which e.g. uses a special hardware
feature which isn't available on all machines where this libc.so will be
used but decidable if available at runtime e.g. via hwcaps, you can provide
two or multiple implementations of foo:
int __foo_default (int __bar)
{
return __bar;
}
int __foo_special (int __bar)
{
return __bar;
}
If your function foo has no libc_hidden_proto (foo) defined for PLT
bypassing, you can use:
#define INIT_ARCH() unsigned long int hwcap = __GLRO(dl_hwcap);
libc_ifunc (foo, (hwcap & HWCAP_SPECIAL) ? __foo_special : __foo_default);
This will define a resolver function for foo which returns __foo_special or
__foo_default depending on your specified expression. Please note that you
have to define a macro function INIT_ARCH before using libc_ifunc macro as
it is called by the resolver function before evaluating the specified
expression. In this example it is used to prepare the hwcap variable.
The resolver function is assigned to an ifunc'ed symbol foo. Calls to foo
from inside or outside of libc.so will be indirected by a PLT call.
If your function foo has a libc_hidden_proto (foo) defined for PLT bypassing
and calls to foo within libc.so should always go to one specific
implementation of foo e.g. __foo_default then you have to add:
__hidden_ver1 (__foo_default, __GI_foo, __foo_default);
or a tweaked definition of libc_hidden_def macro after the __foo_default
function definition. Calls to foo within libc.so will always go directly to
__foo_default. Calls to foo from outside libc.so will be indirected by a
PLT call to ifunc'ed symbol foo which you have to define in a separate
compile unit:
#define foo __redirect_foo
#include <foo.h>
#undef foo
extern __typeof (__redirect_foo) __foo_default attribute_hidden;
extern __typeof (__redirect_foo) __foo_special attribute_hidden;
libc_ifunc_redirected (__redirect_foo, foo,
(hwcap & HWCAP_SPECIAL)
? __foo_special
: __foo_default);
This will define the ifunc'ed symbol foo like above. The redirection of foo
in header file is needed to omit an additional definition of __GI_foo which
would end in a linker error while linking libc.so. You have to specify
__redirect_foo as first parameter which is used within libc_ifunc_redirected
macro in conjunction with typeof to define the ifunc'ed symbol foo.
If your function foo has a libc_hidden_proto (foo) defined and calls to foo
within or from outside libc.so should go via ifunc'ed symbol, then you have
to use:
libc_ifunc_hidden (foo, foo,
(hwcap & HWCAP_SPECIAL)
? __foo_special
: __foo_default);
libc_hidden_def (foo)
The first parameter foo of libc_ifunc_hidden macro is used in the same way
as for libc_ifunc_redirected macro. */

/* The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
macros for each of the OS types we define below. The definitions
of those macros must use the following macros for underlying types.
We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
variants of each of the following integer types on this machine.
16 -- "natural" 16-bit type (always short)
32 -- "natural" 32-bit type (always int)
64 -- "natural" 64-bit type (long or long long)
LONG32 -- 32-bit type, traditionally long
QUAD -- 64-bit type, traditionally long long
WORD -- natural type of __WORDSIZE bits (int or long)
LONGWORD -- type of __WORDSIZE bits, traditionally long
We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
conventional uses of `long' or `long long' type modifiers match the
types we define, even when a less-adorned type would be the same size.
This matters for (somewhat) portably writing printf/scanf formats for
these types, where using the appropriate l or ll format modifiers can
make the typedefs and the formats match up across all GNU platforms. If
we used `long' when it's 64 bits where `long long' is expected, then the
compiler would warn about the formats not matching the argument types,
and the programmer changing them to shut up the compiler would break the
program's portability.
Here we assume what is presently the case in all the GCC configurations
we support: long long is always 64 bits, long is always word/address size,
and int is always 32 bits. */
