Cross-compiling GLib
|
||||
====================
|
||||
|
||||
Cross-compilation is the proceess of compiling a program or
|
||||
library on a different architecture or operating system then
|
||||
it will be run upon. GLib is slightly more difficult to
|
||||
cross-compile than many packages because much of GLib is
|
||||
about hiding differences between different systems.
|
||||
Information about cross-compilation of GLib can be found
|
||||
in the file:
|
||||
|
||||
These notes cover things specific to cross-compiling GLib;
|
||||
for general information about cross-compilation, see the
|
||||
autoconf info pages.
|
||||
docs/reference/glib/docs/reference/glib/html/glib-cross-compiling.html
|
||||
|
||||
GLib tries to detect as much information as possible about
|
||||
the target system by compiling and linking programs without
|
||||
actually running anything; however, some information GLib
|
||||
needs is not available this way. This information needs
|
||||
to be provided to the configure script via a "cache file"
|
||||
or by setting the cache variables in your environment.
|
||||
Or online at:
|
||||
|
||||
As an example of using a cache file, to cross compile for
|
||||
the "MingW32" Win32 runtine environment on a Linux system,
|
||||
create a file 'win32.cache' with the following contents:
|
||||
|
||||
===
|
||||
glib_cv_long_long_format=ll
|
||||
glib_cv_stack_grows=no
|
||||
===
|
||||
|
||||
Then execute the following commands:
|
||||
|
||||
===
|
||||
PATH=/path/to/mingw32-compiler/bin:$PATH
|
||||
chmod a-w win32.cache # prevent configure from changing it
|
||||
./configure --cache-file=win32.cache --host=mingw32
|
||||
===
|
||||
|
||||
The complete list of cache file variables follows. Most
|
||||
of these won't need to be set in most cases.
|
||||
|
||||
Cache file variables
|
||||
====================
|
||||
|
||||
glib_cv_long_long_format=[ll/q/I64]
|
||||
|
||||
Format used by printf and scanf for 64 bit integers. "ll" is
|
||||
the C99 standard, and what is used by the 'trio' library
|
||||
that GLib builds if your printf() is insufficiently capable.
|
||||
Doesn't need to be set if you are compiling using trio.
|
||||
|
||||
glib_cv_stack_grows=[yes/no]
|
||||
|
||||
Whether the stack grows up or down. Most places will want "no",
|
||||
A few architectures, such as PA-RISC need "yes".
|
||||
|
||||
glib_cv_working_bcopy=[yes/no]
|
||||
|
||||
Whether your bcopy can handle overlapping copies. Only needs to be set
|
||||
if you don't have memmove. (Very unlikely)
|
||||
|
||||
glib_cv_sane_realloc=[yes/np]
|
||||
|
||||
Whether your realloc() conforms to ANSI C and can handle NULL as
|
||||
the first argument. Defaults to "yes" and probably doesn't need to be set.
|
||||
|
||||
glib_cv_have_strlcpy=[yes/no]
|
||||
|
||||
Whether you have strlcpy that matches OpenBSD. Defaults to "no",
|
||||
which is safe, since GLib uses a built-in version in that case.
|
||||
|
||||
glib_cv_va_val_copy=[yes/no]
|
||||
|
||||
Whether va_list can be copied as a pointer. If set to "no",
|
||||
then memcopy will be used. Only matters if you don't have
|
||||
va_copy or __va_copy. (So, doesn't matter for GCC.) Defaults
|
||||
to "yes" which is slightly more common than "no".
|
||||
|
||||
glib_cv_rtldglobal_broken=[yes/no]
|
||||
|
||||
Whether you have a bug found in OSF/1 v5.0. Defaults to "no".
|
||||
|
||||
glib_cv_uscore=[yes/no]
|
||||
|
||||
Whether an underscore needs to be prepended to symbols when
|
||||
looking them up via dlsym. Only needs to be set if your system
|
||||
uses dlopen/dlsym.
|
||||
|
||||
ac_cv_func_posix_getpwuid_r=[yes/no]
|
||||
|
||||
Whether you have a getpwuid_r function (in your C library,
|
||||
not your thread library) that conforms to the POSIX spec.
|
||||
(Takes a 'struct passwd **' as the final argument)
|
||||
|
||||
ac_cv_func_nonposix_getpwuid_r=[yes/no]
|
||||
|
||||
Whether you have some variant of getpwuid_r that doesn't
|
||||
conform to to the POSIX spec, but GLib might be able to
|
||||
use (or might segfault.) Only needs to be set if
|
||||
ac_cv_func_posix_getpwuid_r is not set. It's safest to set
|
||||
this to "no".
|
||||
|
||||
glib_cv_use_pid_surrogate=[yes/no]
|
||||
|
||||
Whether to use a setpriority() on the PID of the thread as
|
||||
a method for setting the priority of threads. This only
|
||||
needs to be set when using POSIX threads.
|
||||
|
||||
ac_cv_func_printf_unix98=[yes/no]
|
||||
|
||||
Whether your printf() family supports Unix98 style %N$
|
||||
positional parameters. Defaults to "no".
|
||||
|
||||
ac_cv_func_vsnprintf_c99=[yes/no]
|
||||
|
||||
Whether you have a vsnprintf() with C99 semantics. (C99 semantics
|
||||
means returns the number of bytes that would have been written
|
||||
had the output buffer had enough space.). Defaults to "no".
