I'm thinking that gettext.h needs a slight tweak to work with C++. I'm going off a report from Nelson H. F. Beebe, who tried building m4 on a Linux system with CC=g++:
g++ -I. -pedantic -Wall -W -Wfloat-equal -Wshadow -Wpointer-arith -Wcast-qu al -Wcast-align -Wwrite-strings -Wredundant-decls -Winline -O3 -MT c-stack.o -MD -MP -MF .deps/c-stack.Tpo -c -o c-stack.o c-stack.c gettext.h: In function 'const char* dcpgettext_expr(const char*, const char*, co nst char*, int)': gettext.h:210: error: ISO C++ forbids variable-size array 'msg_ctxt_id' gettext.h: In function 'const char* dcnpgettext_expr(const char*, const char*, const char*, const char*, long unsigned int, int)': gettext.h:256: error: ISO C++ forbids variable-size array 'msg_ctxt_id' g++ (GCC) 4.1.3 20070723 (prerelease) Looking in the source, the problematic lines are guarded by: #if !_LIBGETTEXT_HAVE_VARIABLE_SIZE_ARRAYS but this macro is defined by: #define _LIBGETTEXT_HAVE_VARIABLE_SIZE_ARRAYS \ (((__GNUC__ >= 3 || __GNUG__ >= 2) && !__STRICT_ANSI__) \ /* || __STDC_VERSION__ >= 199901L */ ) I'm thinking that merely adding '&& !defined __cplusplus' in the right place might be enough to resolve the problem, especially since the header is already checking this macro to decide whether to use inline. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
