Patch for configure.in.in that add check for vsnprintf presence in system
it's fixed in 1.2.1-12. thanks for your patch file |
Description of problem: Trying to build koffice from RH8.0 with Intel compiler I got such an error: /bin/sh ../../libtool --silent --mode=compile --tag=CXX g++ -DHAVE_CONFIG_H -I. - I. -I../.. -I../../lib/store -I../../lib/store -I../../lib/kwmf -I../../lib/kwmf -I/usr/include/kde - I/usr/lib/qt3-gcc3.2/include -I/usr/X11R6/include -DQT_THREAD_SUPPORT - D_REENTRANT -Wnon-virtual-dtor -Wno-long-long -Wbad-function-cast -Wundef - Wall -pedantic -W -Wpointer-arith -Wmissing-prototypes -Wwrite-strings - D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion -O2 - D_GNU_SOURCE -O2 -march=i386 -mcpu=i686 -DNO_DEBUG -DNDEBUG -fno- check-new -fno-exceptions -fno-check-new -DQT_CLEAN_NAMESPACE - DQT_NO_ASCII_CAST -DQT_NO_COMPAT -DKDE_NO_COMPAT -c -o koApplication.lo `test -f koApplication.cc || echo './'`koApplication.cc /usr/include/stdio.h(321): error: exception specification is incompatible with that of previous function "snprintf" (declared at line 181 of "../../config.h") __THROW __attribute__ ((__format__ (__printf__, 3, 4))); ^ /usr/include/stdio.h(325): error: exception specification is incompatible with that of previous function "vsnprintf" (declared at line 177 of "../../config.h") __THROW __attribute__ ((__format__ (__printf__, 3, 0))); ^ As you see problem here in conflicting two definitions of vsnprintf; one is in system header stdio.h, second is in config.h, generated in configuration stage. Looking into config.h I found that vsnprintf prototype is guarded by #if: #if !defined(HAVE_VSNPRINTF) || defined(hpux) || defined(__osf__) It's quite competently that it is guarded by HAVE_VSNPRINTF, but there is no something about HAVE_VSNPRINTF in config.h previously! It seems you simply forgot to test for presence of vsnprintf in configuration, that's why extra vsnprintf declaration mistakenly ALWAYS included. I did the patch for configure.in.in that add test for vsnprintf, with it declaration of vsnprintf becomes active only when there is no such in system headers. GNU gcc doesn't expose this bug because it treats such functions as vsnprintf, snprintf (but not fprintf, sprintf, etc) somehow specially and they can be redeclared in difference with others. Version-Release number of selected component (if applicable): koffice-1.2-0.rc1.4 How reproducible: always Steps to Reproduce: 1. I'm afraid this is not reproducible with gcc because of special treating for vsnprintf, snprintf; you could try to reproduce problem using Intel compiler or other third-party compiler, for this just try to build koffice from sources on system that have vsnprintf. Actual results: Compilation error Expected results: Succesfully built package Additional info:
