Building libiberty on Android currently fails with the error message
shown below. This was discovered by trying to build GDBserver
for Android, which stopped building after libiberty became
a GDBserver dependency.
Here is the error message:
[...]/getpagesize.c:64:1: error: redefinition of 'getpagesize'
In file included from /[...]/getpagesize.c:34:0:
/[...]/usr/include/unistd.h:171:23: note: previous definition of 'getpagesize' was here
And looking at the definition, one can see that it defined as
a static inline function...
static __inline__ int getpagesize(void) {
extern unsigned int __page_size;
return __page_size;
}
... which explains why the AC_CHECK_FUNCS test failed to detect
the function, since there is no associated symbol to be linked in.
This patch prevents getpagesize.c to be compiled in by hard-coding
the fact that getpagesize is available on android hosts.
libiberty/ChangeLog:
* configure.ac: Set AC_CV_FUNC_GETPAGESIZE to "yes" on
Android hosts.
* configure: Regenerate.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
