Hi,
Pacman-4.1.0 is released and in the [testing] repos. See my blog [1] for details of what is new in this release.
Cheers, Allan
The new default CPPFLAGS seem to break configure. cpp complains that -D_FORTIFY_SOURCE=2 cannot be used without -O.
I thought it fixed issues (e.g. curl).
Or are we both just taking one package and wildly generalising...?
We are. This is what I got:
configure:6470: checking how to run the C preprocessor configure:6501: gcc -E -D_FORTIFY_SOURCE=2 conftest.c In file included from /usr/include/limits.h:26:0, from /usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.0/include-fixed/limits.h:168, from /usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.0/include-fixed/syslimits.h:7, from /usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.0/include-fixed/limits.h:34, from conftest.c:13: /usr/include/features.h:330:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp] # warning _FORTIFY_SOURCE requires compiling with optimization (-O) ^ configure:6501: $? = 0 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "shellinabox" | #define PACKAGE_TARNAME "shellinabox" | #define PACKAGE_VERSION "2.10" | #define PACKAGE_STRING "shellinabox 2.10" | #define PACKAGE_BUGREPORT "markus@shellinabox.com" | #define PACKAGE_URL "" | #define VCS_REVISION "239" | #define PACKAGE "shellinabox" | #define VERSION "2.10" | /* end confdefs.h. */ | #ifdef __STDC__ | # include <limits.h> | #else | # include <assert.h> | #endif | Syntax error
Confusing here is that there is no error, just a warning, but it still starts retrying different preprocessor command and eventually fails. Appending -O2 to the CPPFLAGS fixed the build.
Yes... this is my pet hate - people who use -Werror and expect their code to be magically immune to any future warnings. And this is even more annoying because it is quite hidden... Fix: sed "s#AC_LANG_WERROR##" configure.ac autoreconf -i Allan
