Dear All, I am new user of Ginac. I am using mingw to for compiling to MSVC. I have succesfully reached several check point according to following link : http://sourceforge.net/apps/mediawiki/ooo-imath/index.php?title=Compiling_un... - Compile GMP -> succesful - Compile CLN -> succesful Now , I am in the step of compiling Ginac. The ./configure results : $ ./configure CC=cl CXX=cl CCAS=cl CXXFLAGS="-DDO_GINAC_ASSERT -ggdb -Wall -ped antic" CPPFLAGS="-DEBUG -MD -EHsc -I../vc/include -I../sdk/include -I../../vc/i nclude -I../../sdk/include -I/usr/local/cln" LIB=../vc/lib:../sdk/lib:../../vc/ lib:../../sdk/lib:/usr/local/lib PKG_CONFIG_PATH=/usr/local/lib/pkgconfig --dis able-shared --enable-static result : === The following minor problems have been detected by configure. === Please check the messages below before running "make". === (see the section 'Common Problems' in the INSTALL file) == ginsh will not compile, because libreadline could not be found. == Documentation may not build, because fig2dev/texinfo is missing. == Reference manual will not build, because doxygen is missing. == Some documentation formats may not build, because latex/pdflatex/dvips is mis sing. As suggested, if I don't want to compile (use) ginsh, I can safely neglect the the warning. However, I got error during make process. ginsh_parser.yy(888) : warning C4100: 'name' : unreferenced formal parameter ginsh_parser.yy(916) : error C3861: 'isatty': identifier not found ginsh_parser.yy(927) : fatal error C1083: Cannot open include file: 'ginsh_op_he lp.h': No such file or directory make[1]: *** [ginsh_parser.obj] Error 2 make[1]: Leaving directory `/mingw/msys/ginac-1.6.2/ginsh' make: *** [all-recursive] Error 1 I dont understand this error message to some extent. It is said that ginsh will not be compiled but why it still compile ginsh. Do I misunderstand the warning ? Please suggest me on this matter. Thanks Chris
