config.guess guesses Solaris 11 to run on a 32-bit platform despite Solaris 11 no longer supporting any 32-bit platform. See the following code at lines 434 to 445: | SUN_ARCH=i386 | # If there is a compiler, see if it is configured for 64-bit objects. | # Note that the Sun cc does not turn __LP64__ into 1 like gcc does. | # This test works for both compilers. | if test "$CC_FOR_BUILD" != no_compiler_found; then | if (echo '#ifdef __amd64'; echo IS_64BIT_ARCH; echo '#endif') | \ | (CCOPTS="" $CC_FOR_BUILD -E - 2>/dev/null) | \ | grep IS_64BIT_ARCH >/dev/null | then | SUN_ARCH=x86_64 | fi | fi If "cc" is installed, i.e. the Oracle Studio compiler, this one is chosen for $CC_FOR_BUILD. This compiler, the gcc provided by Oracle and also gcc bootstrapped from sources on that platform with a default configuration will by default generate 32-bit binaries -- even on a 64-bit platform. And __amd64 will not be defined for compilations targeting a 32-bit platform. This is different from the corresponding behaviour on GNU/Linux systems where the local platform is targeted by default. Thus, as long as you do not add "-m64" or if you have a custom-built gcc which defaults to 64 bit, you will get 32-bit binaries on Solaris despite living on a 64-bit platform. * config.guess (i86pc:SunOS:5.*:* || i86xen:SunOS:5.*:*): Adapt the test by adding the "-m64" flag. This will work properly for Solaris 10 as well (the last Solaris release that supported x86 32-bit platforms). * doc/config.guess.1: Regenerate. Signed-off-by: Dmitry V. Levin <ldv@altlinux.org>

.SH NAME
|
|
config.guess \- guess the build system triplet
|
|
.SH SYNOPSIS
|
|
.B config.guess
|
|
[\fI\,OPTION\/\fR]
|
|
.SH DESCRIPTION
|
|
The GNU build system distinguishes three types of machines, the
|
|
`build' machine on which the compilers are run, the `host' machine
|
|
on which the package being built will run, and, exclusively when you
|
|
build a compiler, assembler etc., the `target' machine, for which the
|
|
compiler being built will produce code.
|
|
|
|
This script will guess the type of the `build' machine.
|
|
.PP
|
|
Output the configuration name of the system `config.guess' is run on.

|
.SH "ENVIRONMENT VARIABLES"
|
|
config.guess might need to compile and run C code, hence it needs a
|
|
compiler for the `build' machine: use the environment variable
|
|
`CC_FOR_BUILD' to specify the compiler for the build machine. If
|
|
`CC_FOR_BUILD' is not specified, `CC' will be used. Be sure to
|
|
specify `CC_FOR_BUILD' if `CC' is a cross-compiler to the `host'
|
|
machine.
|
|
|
|
CC_FOR_BUILD a native C compiler, defaults to `cc'
|
|
CC a native C compiler, CC_FOR_BUILD is preferred
|
|
