Hello, I tried to compile ginac version 1.3.3 with gcc 4.0.0 (Apple version) on a Intel iMac running OS X 10.4.5. My version of libread is 5.1. I append the config.log. The first error is that the configure script can still not find the correct version of cln, although it should be installed correctly. I tried to play a bit, but was not able to fix it. Running 'configure --disable-clntest --enable-shared=no' and typing 'make' produces: ... ginsh_parser.yy:47:6: error: missing binary operator before token "wrapper" ginsh_parser.yy:53:6: error: missing binary operator before token "wrapper" ginsh_parser.yy:845:6: error: missing binary operator before token "wrapper" ginsh_parser.yy:855:6: error: missing binary operator before token "wrapper" I edited the file config.h changing the lines /* Major version of installed readline library. */ #define GINAC_RL_VERSION_MAJOR EditLine wrapper /* Minor version of installed readline library. */ #define GINAC_RL_VERSION_MINOR EditLine wrapper into /* Major version of installed readline library. */ #define GINAC_RL_VERSION_MAJOR 1 /* Minor version of installed readline library. */ #define GINAC_RL_VERSION_MINOR 3 But running 'make' then produced: ...
