I know others on this list have built Festival under Slackware 9.0. However, I decided to try it out and can't even get the speech tools to build. After running the make all the way to the end, it bombs at the linker with this: g++ -O3 -fno-shared-data -Wall -o ch_lab ch_lab_main.o -L../lib -lestools -L../lib -lestbase -L../lib -leststring -ltermcap -ldl -lm -lstdc++ ../lib/libestbase.so: undefined reference to `std::__pad<char, std::char_traits<char> >::_S_pad(std::ios_base&, char, char*, char const*, int, int, bool)' collect2: ld returned 1 exit status make[1]: *** [ch_lab] Error 1 make: *** [main] Error 2 So, anybody else get this and what was the work-around? Am I missing some library or something perhaps?
