Hi,
I recently updated a configure script for a project I am working on
and thought that simply ensuring that the availability of the 10.4u
SDK was enough to be able to build a universal binary. When I run
this make file resulting from the configure script I get told that:
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning fat file: /
usr/lib/libSystem.dylib does not contain an architecture that
matches the specified -arch flag: i386 (file ignored)
Is it not possible to build a universal binary on a PowerPC based
system?
If it is using the system library instead of the SDK library, you
have improperly specified your arguments. Most likely you have
installed new tools on an old system which predates Intel support,
and failed to use the appropriate argument to the "-syslibroot"
directive to the linker.
Should I be using -isysroot or -syslibroot?
The Mac specific sections looks like:
AC_PATH_PROG(XCODE_SELECT,xcode-select,no)
further on:
#fix_mac_groups
#fix_parameters $JPATH/lib/javax.comm.properties
if test $XCODE_SELECT = no; then
SDKPATH="/Developer"
else
SDKPATH=`$XCODE_SELECT -print-path`
fi
SDK="$SDKPATH/SDKs/MacOSX10.4u.sdk"
if test "x$enable_universallib" != xno; then
if test -d "/Developer/SDKs/MacOSX10.4u.sdk"; then
echo "library os.arch... universal (i386 ppc)"
echo "SDK: $SDK"
CFLAGS="$CFLAGS -O -g -mmacosx-version-
min=10.4 -isysroot $SDK -arch i386 -arch ppc"
LDFLAGS="$LDFLAGS -arch i386 -arch ppc"
else
echo "Warning: no universal SDK, will not
build universal"
echo "library os.arch... "${OS_ARCH}
fi
else
echo "User disabled building of universal library"
echo "library os.arch... "${OS_ARCH}
fi
GLIBTOOL="\$(SHELL) glibtool"
LINK="cc $LDFLAGS -bundle -framework CoreFoundation -
framework IOKit -o librxtx\$*.jnilib "
OBJECT_EXTENSION="o"
LIB_EXTENSION="jnilib"
Does this look right? Note this build find with Intel/10.5.1 but fails
with PPC/10.4.11
