Hi Mike,
I've done the following:
Specify the environment variables:
export CFLAGS="-arch i386 -arch x86_64"
export CXXFLAGS="-arch i386 -arch x86_64"
export LDFLAGS="-arch i386 -arch x86_64"
Configure and build :
./configure
make
This results in the following error for libpng-1.2.31
/bin/sh ./libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -
DPNG_CONFIGURE_LIBPNG -arch i386 -arch x86_64 -MT libpng12_la-
png.lo -MD -MP -MF .deps/libpng12_la-png.Tpo -c -o libpng12_la-png.lo
`test -f 'png.c' || echo './'`png.c
libtool: compile: gcc -DHAVE_CONFIG_H -I. -DPNG_CONFIGURE_LIBPNG -
arch i386 -arch x86_64 -MT libpng12_la-png.lo -MD -MP -MF .deps/
libpng12_la-png.Tpo -c png.c -fno-common -DPIC -o .libs/libpng12_la-
png.o
gcc-4.0: -E, -S, -save-temps and -M options are not allowed with
multiple -arch flags
make[1]: *** [libpng12_la-png.lo] Error 1
make: *** [all] Error 2
How can I disable -save-temps and -M options?
The ./configure --help doesnt give much or document this.
elvis-dowsons-macbook-pro:libpng-1.2.31 elvis$ ./configure --help
`configure' configures libpng 1.2.31 to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included
packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or
`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in
PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in
EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data
[PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root
[PREFIX/share]
--datadir=DIR read-only architecture-independent data
[DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/libpng]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]
Program names:
--program-prefix=PREFIX prepend PREFIX to installed
program names
--program-suffix=SUFFIX append SUFFIX to installed
program names
--program-transform-name=PROGRAM run sed PROGRAM on installed
program names
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST
[BUILD]
Optional Features:
--disable-option-checking ignore unrecognized --enable/--with
options
--disable-FEATURE do not include FEATURE (same as --enable-
FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-maintainer-mode enable make rules and dependencies not
useful
(and sometimes confusing) to the casual installer
--disable-dependency-tracking speeds up one-time build
--enable-dependency-tracking do not reject slow dependency
extractors
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-static[=PKGS] build static libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--disable-libtool-lock avoid locking (might break parallel builds)
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-
PACKAGE=no)
--with-gnu-ld assume the C compiler uses GNU ld
[default=no]
--with-pic try to use only PIC/non-PIC objects
[default=use
both]
--with-pkgconfigdir Use the specified pkgconfig dir (default is
libdir/pkgconfig)
--with-binconfigs Generate shell libpng-config scripts as
well as
pkg-config data [default=yes]
--with-libpng-compat Generate the obsolete libpng.so library
[default=yes]
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include
dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
Use these variables to override the choices made by `configure' or to
help
it to find libraries and programs with nonstandard names/locations.
Best regards,
Elvis Dowson
