Unsuccessful MAGIC installation

[miguelsofo]

Hi, I been trying to install MAGIC in:

Distributor ID: Ubuntu
Description: Ubuntu 20.04.5 LTS
Release: 20.04
Codename: focal

I been following the: ./configure, make, make install steps.

during make, prints several warnings, and at the end the following:

display.c: In function ‘rl_redisplay’:
display.c:602:15: error: implicit declaration of function ‘wcwidth’ [-Werror=implicit-function-declaration]
602 | temp = wcwidth (wc);

The error with make install is:

: warning: "CAD_DIR" redefined
: note: this is the location of the previous definition
make[2]: *** No rule to make target '../garouter/libgarouter.o', needed by 'magic'. Stop.
make[2]: *** No rule to make target '../utils/libutils.a', needed by 'net2ir'. Stop.

Here are the outputs.

config.txt
make.txt
make_install.txt

I also tried with ./configure --disable-readline without succeed.

Any ideas?
Thank you!

display.c in the readline code needs #include <wchar.h>, according to the man page for wcwidth.

However, the fact that readline is compiling suggests that you are compiling the non-Tcl/Tk version of magic, which will cause you to lose a huge number of features. I suggest making sure that you have all the dependencies, in particular the tcl-dev and tk-dev packages.

Thank you!

I did:

./configure --with-tcl --disable-readline --with-opengl --with-tk
Make
Sudo make install

and everything runed smoothly.

The original problem reported here is believed to be properly fixed via this recent commit in the queue 4ec7467

While I understand the OP may have worked around the issue by using apt-get install libreadline-dev so the magic configure detects the system libreadline and uses it instead.

Maybe an upgraded readline (current is 8.x) if we look here:
https://git.savannah.gnu.org/cgit/readline.git/tree/display.c
https://git.savannah.gnu.org/cgit/readline.git/tree/config.h.in

We can see at some point readline was changed due to incorrect use of feature_test_macros(7)
The #define was removed and put into the TOP of config.h which is always the first #include.
