To Whom It May Concern: I am using: Operating system: SunOS samsun 5.6 Generic_105181-03 sun4u sparc SUNW,Ultra-Enterprise Compiler: egcs-2.91.57 CLN: version 1.0.2 CLN and GiNaC are configured with default settings, except that CLN is only shared libraries. My linker is complaining about undefined symbols in 'ginsh_parser.o'. Any way that you can help is greatly appreciated. Here is the output from make: make all-recursive make[1]: Entering directory `/dumptruck/GiNaC-0.4.1' Making all in ginac make[2]: Entering directory `/dumptruck/GiNaC-0.4.1/ginac' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/dumptruck/GiNaC-0.4.1/ginac' Making all in check make[2]: Entering directory `/dumptruck/GiNaC-0.4.1/check' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/dumptruck/GiNaC-0.4.1/check' Making all in ginsh make[2]: Entering directory `/dumptruck/GiNaC-0.4.1/ginsh' /bin/sh ../libtool --mode=link g++ -g -O2 -o ginsh ginsh_parser.o ginsh_lexer.o ../ginac/libginac.la -lcln -lstdc++ g++ -g -O2 -o .libs/ginsh ginsh_parser.o ginsh_lexer.o ../ginac/.libs/libginac.so -lcln -lstdc++ -lcln -lstdc++ -R/usr/local/lib Undefined first referenced symbol in file rl_basic_word_break_characters ginsh_parser.o rl_readline_name ginsh_parser.o filename_completion_function ginsh_parser.o completion_matches ginsh_parser.o rl_completion_append_character ginsh_parser.o rl_line_buffer ginsh_parser.o rl_attempted_completion_function ginsh_parser.o ld: fatal: Symbol referencing errors.
