#21789 [Opn]: GCC 3.2.1 needs stdc++ linked

ID: 21789 User updated by: ron@imperators.ca Reported By: ron@imperators.ca Status: Open Bug Type: Compile Failure Operating System: Solaris 8 PHP Version: 4.3.0 New Comment: Thanks for the notes. The fix you described was similar to what I actually did to solve the problem, but since it was happening under Solaris 8, the solution wasn't exactly as described. I would like to suggest the addition of a flag (--enable-stdc++) to the configure script so that the same operation could be achieved more easily by any user having similar problems, regarless of platform, OS or shell. Ron.

Pavel Hlavnicka from Ginger Alliance suggested exporting the c++ compiler flag. 7. cd /usr/local/php/php-4.3.0 8. .configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-zlib --with-dom --with-gd --enable-xslt --with-xslt-sablot --with-sablot-js 9. make 10. make install ------------------------------------------------------------------------ [2003-01-21 07:30:51] ron@imperators.ca Yes, Sablotron was compiled with the same version of GCC. ------------------------------------------------------------------------ [2003-01-21 01:15:41] sniper@php.net Was the sablot compiled also with that same GCC version? ------------------------------------------------------------------------ [2003-01-20 23:43:57] ron@imperators.ca With GCC 3.2.1 these symbols can be found in libstdc++. When php 4.3.0 is linked with -lsablot, there is no easy way to link it to stdc++, to account for the changes of the locations of these functions in the new GCC API. I would recommend a configure option like --enable-stdc++ to allow the user to link this manually like --enable-libgcc. excerpt from compile : .lo main/internal_functions_cli.lo -lsablot -liconv -lexpat -liconv -lcurl -lcrypt -lresolv -lm -ldl -lnsl -lsocket -lgcc -lcrypt -lcurl -lz -lssl -lcrypto -ldl -lsocket -lnsl -lz -o sapi/cli/php Undefined first referenced symbol in file __cxa_pure_virtual /usr/local/lib/libsablot.so vtable for __cxxabiv1::__si_class_type_info/usr/local/lib/libsablot.so vtable for __cxxabiv1::__vmi_class_type_info/usr/local/lib/libsablot.so operator new[](unsigned) /usr/local/lib/libsablot.so vtable for __cxxabiv1::__class_type_info/usr/local/lib/libsablot.so operator delete(void*) /usr/local/lib/libsablot.so operator new(unsigned) /usr/local/lib/libsablot.so __gxx_personality_v0 /usr/local/lib/libsablot.so operator delete[](void*) /usr/local/lib/libsablot.so ld: fatal: Symbol referencing errors.
