When I do "configure --with-included-strings", the output says: [...] checking whether the included std::string should be used... checking ... no checking whether the systems std::string is really good... no [...] But src/config.h contains: [...] /* Define to use the lyxstring class bundled with LyX. */ /* #undef USE_INCLUDED_STRING */ /* Define if the systems std::string is really good. */ /* #undef STD_STRING_IS_GOOD */ [...] This is on both, my Linux and FreeBSD PC. Is something wrong with treating the --with-included-strings flag? Since my FreeBSD PC exhibits this strange SIGSEGV crash in math_factory.C, I modified manually src/config.h to: #define USE_INCLUDED_STRING 1 But also that doesn't help. What happens at the end of readSymbols::math_factory.C and why only on my FreeBSD PC does this end with a SIGSEGV? I'm really keen on solving this, since LyX-CVS on my FreeBSD is unusable, since any math environment will cause a SIGSEGV crash. Regards, Rob.
