Hi,
With gcc 4.8.0-4 I can no longer build core/links package from ABS,
with SSL support. The issue is _not_related to makepkg (as I originally
thought), even plain ./configure fails if I export
CPPFLAGS=-D_FORTIFY_SOURCE=2, regardless of the content of {C,CXX,LD}FLAGS.
Here is the error:
--------------------
$ ./configure --with-ssl
[ ... ]
checking for openssl... yes
checking OPENSSL_CFLAGS...
checking OPENSSL_LIBS... -lssl -lcrypto
checking for OpenSSL... no
checking for OpenSSL... no
configure: error: OpenSSL not found
$ cat config.log
[ ... ]
configure:8095: checking for openssl
configure:8102: checking OPENSSL_CFLAGS
configure:8107: checking OPENSSL_LIBS
configure:8139: checking for OpenSSL
configure:8150: gcc -o conftest -g -O2 -D_FORTIFY_SOURCE=2   conftest.c
-lssl
-lcrypto  -lm  1>&5
In file included from configure:8143:0:
confdefs.h:8:16: error: duplicate 'unsigned'
 #define size_t unsigned
                ^
configure: failed program was:
#line 8143 "configure"
#include "confdefs.h"
#include 
int main() {
SSLeay_add_ssl_algorithms()
; return 0; }
--------------------
With gcc 4.7.2 all builds fine with Arch's default makepkg.conf, i.e. no
"duplicate unsigned error". Also, unsetting CPPFLAGS allows a successfull
build.
Since core/links has been successfully rebuilt, what was the gcc version?
ANd
can anyone else confirm the above issue?
TIA,
L.
Aready fixed in links in testing. Just add a prepare function with:
  sed -i "/ac_cpp=/s/\$CPPFLAGS/\$CPPFLAGS -O2/" configure
I see, thank you. Alternatively one could simply do CPPFLAGS+=" -O2" in
PKGBUILD...

I'm still confused though: are we supposed to pass -On flags to cpp now (this
is even mentioned against in the configure script)? Or is it still a
gcc/glibc problem?

THanks again,
L.
