Hi Kwan, re: > Is there a way I can try to find out whether yacc exists? Most (but not all) Linux distributions come with a utility named 'locate'. If the system is setup to index its content (this is automatic on most Linux systems that have locate, but it is not guaranteed), then you can run: locate yacc If things are setup, you would get a listing that looks something like: mcidas@odroidU3:~$ locate yacc /etc/alternatives/yacc /etc/alternatives/yaccman /home/mcidas/mcidas2015/hdf/mfhdf/ncgen/lexyacc.com /home/mcidas/mcidas2016/hdf/mfhdf/ncgen/lexyacc.com /usr/bin/bison.yacc /usr/bin/yacc /usr/include/gtk-3.0/gtk/a11y/gtkentryaccessible.h /usr/share/automake-1.14/am/yacc.am /usr/share/bison/yacc.c /usr/share/man/man1/bison.yacc.1.gz /usr/share/man/man1/yacc.1.gz /usr/share/medit/language-specs/yacc.lang /usr/share/vim/vim74/indent/yacc.vim /usr/share/vim/vim74/syntax/ayacc.vim /usr/share/vim/vim74/syntax/yacc.vim /var/lib/dpkg/alternatives/yacc re: > I am thinking > perhaps some env variables are missing when the .cshrc was stripped to bear > minimum for McIDAS installation. The stripped down cshrc file that I sent did basically assumed that the packages that are needed for a build were installed in normal system locations and so the utilities will be found by virtue of the standard PATH that is defined by the system for all users.
