[[bbv2.reference.tools.compiler.gcc]]
= GNU C++
The `gcc` module supports the http://gcc.gnu.org[GNU C++ compiler] on
Linux, a number of Unix-like system including SunOS and on Windows
(either http://www.cygwin.com[Cygwin] or http://www.mingw.org[MinGW]).
The `gcc` module is initialized using the following syntax:
----
using gcc : [version] : [c++-compile-command] : [compiler options] ;
----
This statement may be repeated several times, if you want to configure
several versions of the compiler.
If the version is not explicitly specified, it will be automatically
detected by running the compiler with the `-v` option. If the command is
not specified, the `g++` binary will be searched in PATH.
The following options can be provided, using
_`<option-name>option-value syntax`_:
`cflags`::
Specifies additional compiler flags that will be used when compiling C
sources.
`cxxflags`::
Specifies additional compiler flags that will be used when compiling C++
sources.
`compileflags`::
Specifies additional compiler flags that will be used when compiling both C
and C++ sources.
`linkflags`::
Specifies additional command line options that will be passed to the linker.
`root`::
Specifies root directory of the compiler installation. This option is
necessary only if it is not possible to detect this information from the
compiler command--for example if the specified compiler command is a user
script.
`archiver`::
Specifies the archiver command that is used to produce static
libraries. Normally, it is autodetected using gcc `-print-prog-name`
option or defaulted to `ar`, but in some cases you might want to
override it, for example to explicitly use a system version instead of
one included with gcc.
`ranlib`::
Specifies the ranlib command that is used to generated symbol table
for static libraries. Normally, it is autodetected using gcc
`-print-prog-name` option or defaulted to `ranlib`, but in some cases
you might want to override it, for example to explicitly use a system
version instead of one included with gcc.
`rc`::
Specifies the resource compiler command that will be used with the
version of gcc that is being configured. This setting makes sense only
for Windows and only if you plan to use resource files. By default
`windres` will be used.
`rc-type`::
Specifies the type of resource compiler. The value can be either
`windres` for msvc resource compiler, or `rc` for borland's resource
compiler.
In order to compile 64-bit applications, you have to specify
`address-model=64`, and the `instruction-set` feature should refer to a 64
bit processor. Currently, those include `nocona`, `opteron`, `athlon64` and
`athlon-fx`.

# On AIX we *have* to use the native linker.
#
# Using -brtl, the AIX linker will look for libraries with both the .a
# and .so extensions, such as libfoo.a and libfoo.so. Without -brtl, the
# AIX linker looks only for libfoo.a. Note that libfoo.a is an archived
# file that may contain shared objects and is different from static libs
# as on Linux.
#
# The -bnoipath strips the prepending (relative) path of libraries from
# the loader section in the target library or executable. Hence, during
# load-time LIBPATH (identical to LD_LIBRARY_PATH) or a hard-coded
# -blibpath (*similar* to -lrpath/-lrpath-link) is searched. Without
# this option, the prepending (relative) path + library name is
# hard-coded in the loader section, causing *only* this path to be
# searched during load-time. Note that the AIX linker does not have an
# -soname equivalent, this is as close as it gets.
#
# The -bbigtoc option instrcuts the linker to create a TOC bigger than 64k.
# This is necessary for some submodules such as math, but it does make running
# the tests a tad slower.
#
# The above options are definitely for AIX 5.x, and most likely also for
# AIX 4.x and AIX 6.x. For details about the AIX linker see:

# *still* in liba.a
#
# Rene Rivera:
#
# Originally removing the archive was done by splicing an RM onto the

# many files because it will no longer execute the action directly and blow
# the line length limit. Instead we remove the file in a different action,
# just before building the archive.
