Hi all! I'm new user of linux. I've installed an Ubuntu 7.10. I need to install Ginac for some scientific programs. But I get this problem while doing "./configure" ===The following minor problems have been detected by configure. ===Pleas check .... === I could not find the headers for libreadline (needed for building ginsh). ===I could not find libreadline (needed by ginsh). ------------------------ I've read the Install file and Common problems. I found that there is installed libreadline5.2-3build1 After I've read from Ginac mailing list archives similar problems, but i can't det the main idea. I found in my config.log life these rows configure:22223: checking readline/readline.h usability configure:22240: g++ -c -g -O2 conftest.cpp >&5 conftest.cpp:63:31: error: readline/readline.h: No such file or directory configure:22246: $? = 1 configure: failed program was: | /* confdefs.h. */ | #define PACKAGE_NAME "GiNaC" | #define PACKAGE_TARNAME "ginac" ....... ................................ | #include <readline/readline.h> configure:22260: result: no configure:22264: checking readline/readline.h presence configure:22279: g++ -E conftest.cpp conftest.cpp:30:31: error: readline/readline.h: No such file or directory configure:22285: $? = 1 configure: failed program was: | /* confdefs.h. */ | #define PACKAGE_NAME "GiNaC" ................................................. | #include <readline/readline.h> configure:22299: result: no configure:22332: checking for readline/readline.h configure:22340: result: no configure:22223: checking readline/history.h usability configure:22240: g++ -c -g -O2 conftest.cpp >&5 conftest.cpp:63:30: error: readline/history.h: No such file or directory configure:22246: $? = 1 configure: failed program was: | /* confdefs.h. */ | #define PACKAGE_NAME "GiNaC" ................................................. what is the problem? Thank you Hayk p.s. I don't know can I attach for example config.log file in my mail?
