Compiling 3.4.1 fails on Debian Wheezy

[gangli]

This is the first time i'm poking around in Angband caverns since the olden days of the menacing presence of Thangorodrim.... and I'd love to elaborate on the countless hours wasted dungeon crawling through Zangband and Angband, but more urgent matters prompted me to have a look here. So, I'm not happy with the official Debian Wheezy package of Angband (I believe it's 3.3 something) . That's why I'm trying to compile it myself from the source ver 3.4.1

I've both ncurses and ncursesw (and both bin and dev pkgs) installed on the system (as mentioned before : Debian Wheezy, 64bit).

The "./configure" line is as follows:

CFLAGS="-O3 -mtune=native" ./configure --prefix=$HOME/local/ --with-x --with-ncurses-prefix="/lib/x86_64-linux-gnu" --with-ncurses-exec-prefix="/usr"

The make fails _after_ building main-gcu.c with the following type of error messages:

...
main-gcu.c:(.text+0x628): undefined reference to `stdscr'
main-gcu.c:(.text+0x630): undefined reference to `wgetch'
main-gcu.c:(.text+0x641): undefined reference to `cbreak'
main-gcu.c:(.text+0x667): undefined reference to `stdscr'
main-gcu.c:(.text+0x674): undefined reference to `nodelay'
main-gcu.c:(.text+0x67b): undefined reference to `stdscr'
main-gcu.c:(.text+0x683): undefined reference to `wgetch'
main-gcu.c:(.text+0x6a2): undefined reference to `stdscr'
main-gcu.c:(.text+0x6aa): undefined reference to `wgetch'
main-gcu.c:(.text+0x751): undefined reference to `ungetch'
...

Obviously some library is either missing, or its link path is missing/wrong. I hope you people can point to a solution.

The "./configure" line is as follows:

CFLAGS="-O3 -mtune=native" ./configure --prefix=$HOME/local/ --with-x --with-ncurses-prefix="/lib/x86_64-linux-gnu" --with-ncurses-exec-prefix="/usr"

configure expects a valid ncursesw5-config executable in $ncurses_exec_prefix/bin/ncursesw5-config or, if that's not set, in $ncurses_prefix/bin/ncursesw5-config. Does /usr/bin/ncursesw5-config --libs output linker options that point to a valid ncursesw library? You may also want to check config.log for references to ncurses.

Thanks for the reply. ncursesw5-config is present and in /usr/bin.

Output of ncursesw5-config --libs is -lncursesw -ltinfo

Both libraries are in /usr/lib/x86_64-linux-gnu (and this is also the output of ncursesw5-config --libdir)

grepping for ncurses in config.log (grep -i ncurs -A2) gives the following:

  $ ./configure --prefix=/home/todor/local --with-x --with-ncurses-exec-prefix=/usr --with-ncurses-prefix=/usr/lib/x86_64-linux-gnu

Output of ncursesw5-config --libs is -lncursesw -ltinfo

This is a little suspicious. I wonder whether /usr/lib/x86_64-linux-gnu is in your linker's default search path. If not, it won't be able to find the libraries without -L/usr/lib/x86_64-linux-gnu. If these are system packages, though, they should be set up coherently...

grepping for ncurses in config.log (grep -i ncurs -A2) gives the following:

  $ ./configure --prefix=/home/todor/local --with-x --with-ncurses-exec-prefix=/usr --with-ncurses-prefix=/usr/lib/x86_64-linux-gnu

Could you go a few lines farther in the file here? When I run configure, I get

configure:4914: checking for ncurses - wide char support
configure:4946: gcc -o conftest -g -O2 -DHAVE_CONFIG_H -W -Wall -Wextra -Wno-unused-parameter -pedantic -Wno-missing-field-initializers -I/usr/include/ncursesw  -I.  conftest.c  -L/usr/lib -lncursesw -ltinfo >&5
configure:4946: $? = 0
configure:4946: ./conftest

configure:4960: result: yes

NCURSES_CFLAGS=''
NCURSES_CONFIG='/usr/bin/ncursesw5-config'
NCURSES_LIBS=''
NOINSTALL=''

This is very suspicious. NCURSES_LIBS should be the output of ncursesw5-config --libs.

Mine is similar:

configure:4916: gcc -o conftest -O3 -mtune=native -DHAVE_CONFIG_H -fno-strength-reduce -W -Wall -Wno-unused-parameter -pedantic -Wno-missing-field-initializers   -I.  conftest.c   >&5
configure:4916: $? = 0
configure:4916: ./conftest
configure:4916: $? = 0
configure:4930: result: yes

Immediately afterwards though , the "mvwaddnwstr" , "use_default_colors" and "can_change_colors" tests fail with a linker error. For example:

...
configure:5009: checking for can_change_color
configure:5009: gcc -o conftest -O3 -mtune=native -DHAVE_CONFIG_H -fno-strength-reduce -W -Wall -Wno-unused-parameter -peda
ntic -Wno-missing-field-initializers   -I.  conftest.c   >&5
/tmp/ccgkn5Nw.o: In function `main':
conftest.c:(.text.startup+0x7): undefined reference to `can_change_color'
collect2: error: ld returned 1 exit status
configure:5009: $? = 1

...

Could this be related?

Whoa. Just tried to configure it for the first time without any additional flags, and the CFLAGS redefinition. And ... at least the configure script works.


It turns out that adding `exec-prefix' flag messed up things. Leaving everything else the same, and throwing that flag away did the job. I started using this, because the script failed to recognise the existence of a freshly installed ncursesw dev package. The system was rebooted between the attempts, so maybe that helped. I don't know. In any case, thanks for trying to help!
