trouble with ncursesw-dev when compiling for Pure64 11.0-beta

<< < (3/3)

GNUser:
Thank you, jazzbiker. Thanks to you I was also able to figure it out using a different approach:

In configure I changed these lines:

--- Code: ---for ac_lib in '' tinfo curses ncurses; do
...
   for ac_header in curses.h term.h ncurses/curses.h ncurses/term.h termcap.h

--- End code ---

to this:

--- Code: ---for ac_lib in '' tinfo curses ncursesw; do
...
   for ac_header in curses.h term.h ncursesw/curses.h ncursesw/term.h ncursesw/termcap.h

--- End code ---

In src/lftp_tinfo.cc I changed these lines:


--- Code: ---#else
# error No header file for tigetstr or tgetstr found. Install ncurses-dev or termcap-dev.
#endif
...
   if(setupterm(NULL, 1, &errret) == ERR)

--- End code ---

To this:

--- Code: ---#else
#  include <ncursesw/term.h>
#endif
...
   if(setupterm(NULL, 1, &errret) == -1)

--- End code ---

The change to the else clause was key because it's where the logic was going and because the infamous tigetstr function header is in ncursesw/term.h only. ERR is not defined in term.h but is defined elsewhere as -1.

After those changes to the source code (to configure and src/lftp_tinfo.cc), things were straight-forward:

--- Code: ---$ tce-load -i compiletc gettext-dev libidn2-dev ncursesw-dev readline-dev pkg-config openssl-1.1.1-dev
$ export CFLAGS="-mtune=generic -Os -pipe"
$ export CXXFLAGS="-mtune=generic -Os -pipe"
$ export LDFLAGS="-Wl,-O1"
$ ./configure --prefix=/usr/local --without-gnutls --with-openssl
$ make
--- End code ---

There's no way I would have been able to crack this without your help. THANK YOU! :D

jazzbiker:
Oh, no thanks, I'm glad to help a little bit when I'm able to. Its pleasant when the job is done, but its double pleasant if something was taught along the way. Thank You for giving such a possibility )))

This was key. Before you found it and shared it, I wasn't even sure I was on the right track.
Thanks again :)
I'm rocking lftp 4.9.1 now, and will contribute it as an extension in the near future.

I feel your pain. PHP, net-snmp, and iftop also require hacks in their build scripts to compile with ncursesw. Finding those hacks takes a while, and can change with versions.
