Hi, This is something I've seen with synergy 1.2.7 which builds fine on FC4 and older : After an autoreconf on FC development, configure fails to detect X, the reason being : (sorry, some line breaks get mangled by sylpheed...) :^configure:5738: checking for X configure:5843: g++ -E conftest.cc configure:5849: $? = 0 configure:5899: g++ -o conftest -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -g conftest.cc -lXt >&5 /usr/include/X11/Xlib.h: In function 'int main()': /usr/include/X11/Xlib.h:1492: error: too many arguments to function 'void XrmInitialize()' conftest.cc:46: error: at this point in file configure:5905: $? = 1 configure: failed program was: | /* confdefs.h. */ | | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PACKAGE "synergy" | #define VERSION "1.2.7" | #ifdef __cplusplus | extern "C" void std::exit (int) throw (); using std::exit; | #endif | #define HAVE_POSIX_SIGWAIT 1 | #define HAVE_PTHREAD_SIGNAL 1 | #define HAVE_PTHREAD 1 | #define HAVE_NANOSLEEP 1 | #define HAVE_INET_ATON 1 | #define STDC_HEADERS 1 | #define HAVE_SYS_TYPES_H 1 | #define HAVE_SYS_STAT_H 1 | #define HAVE_STDLIB_H 1 | #define HAVE_STRING_H 1 | #define HAVE_MEMORY_H 1 | #define HAVE_STRINGS_H 1 | #define HAVE_INTTYPES_H 1 | #define HAVE_STDINT_H 1 | #define HAVE_UNISTD_H 1 | #define HAVE_UNISTD_H 1 | #define HAVE_SYS_TIME_H 1 | #define HAVE_SYS_TYPES_H 1 | #define HAVE_LOCALE_H 1 | #define HAVE_WCHAR_H 1 | #define HAVE_ALLOCA_H 1 | #define HAVE_SYS_SOCKET_H 1 | #define HAVE_SYS_SELECT_H 1 | #define HAVE_SYS_UTSNAME_H 1 | #define HAVE_ISTREAM 1 | #define HAVE_OSTREAM 1 | #define HAVE_SSTREAM 1 | #define TIME_WITH_SYS_TIME 1 | /* end confdefs.h. */ | #include <X11/Xlib.h> | int | main () | { | XrmInitialize (0) | ; | return 0; | } configure:5958: result: no After a quick glance, I see nothing weird in configure.in. Could this be related to the recent changes in X detection? (it used to be Intrinsic.h being checked IIRC). If this seems to be indeed an autoconf bug, I'll gladly report it in bugzilla.
