Bug ID: 1683
Summary: libpcrecpp recipe does not honor -force_cpusubtype_ALL
on OS X
Product: PCRE
Version: 8.37
Hardware: Other
OS: MacOS X
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: ph10@???
Reporter: noloader@???
CC: pcre-dev@???
I am using the original PCRE library due to Git (Git requires it, and its
`configure` fails a check for `pcre_version` if using PCRE2). I configured with
the following:
export CFLAGS="-arch ppc -force_cpusubtype_ALL"
export LDFLAGS="-Wl,-force_cpusubtype_ALL"
./configure --enable-static --enable-shared --enable-utf --enable-pcre8 \
--enable-pcre16 --enable-pcre32 --enable-unicode-properties \
--enable-newline-is-any --enable-pcregrep-libz --enable-pcregrep-libbz2 \
--with-gnu-ld --prefix=/usr/local/ppc
I then did the same for PPC64 using "export CFLAGS="-arch ppc64
-force_cpusubtype_ALL"
When I attempted to build a fat libpcrecpp.a, it resulted in an error:
sudo lipo -create /usr/local/ppc/lib/libpcrecpp.a \
/usr/local/ppc64/lib/libpcrecpp.a \
-output /usr/local/lib/libpcrecpp.a
lipo: /usr/local/ppc/lib/libpcrecpp.a and
/usr/local/ppc64/lib/libpcrecpp.a have the same architectures (ppc7400)
and can't be in the same fat output file
Based on:
$ lipo -info /usr/local/ppc/lib/libpcrecpp.a
input file /usr/local/ppc/lib/libpcrecpp.a is not a fat file
Non-fat file: /usr/local/ppc/lib/libpcrecpp.a is architecture: ppc7400
$ lipo -info /usr/local/ppc64/lib/libpcrecpp.a
input file /usr/local/ppc64/lib/libpcrecpp.a is not a fat file
Non-fat file: /usr/local/ppc64/lib/libpcrecpp.a is architecture: ppc7400
I'm guessing libpcrecpp is not utilizing CFLAGS.
The other library recipes do honor CFLAGS and the options "-arch ppc
-force_cpusubtype_ALL", and lipo creates the fat binaries.
