Cannot build target ARM with Ubuntu 16.04

[Evanok]

Hi.

I am able to build default target on my host (x86_64 arch) on ubuntu 16.04. But I need to build crash for ARM target.
So I run command : make target=ARM as suggested in the documentation.

Result :

configure: WARNING: no enhanced curses library found; disabling TUI
checking for library containing tgetent... no
configure: error: no termcap library found
Makefile:8235: recipe for target 'configure-gdb' failed
make[3]: *** [configure-gdb] Error 1
Makefile:834: recipe for target 'all' failed
make[2]: *** [all] Error 2

crash build failed

Makefile:229: recipe for target 'gdb_merge' failed
make[1]: *** [gdb_merge] Error 1
Makefile:224: recipe for target 'all' failed
make: *** [all] Error 2

I check and libncurses is already installed :

[arthur * (HEAD detached at 7.2.1)] sudo apt-get install libncurses5
[sudo] password for arthur: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libncurses5 is already the newest version (6.0+20160213-1ubuntu1).

I tried to build it with last master and last tag (7.2.1) without more success.
Do I miss something ?

Thanks,
Eva.

I can't speak to the details of Ubunutu packaging, so I'll have to reference RPM-based host build systems. With "make target=ARM" you are actually building a 32-bit x86 binary, and therefore it needs the 32-bit version of the ncurses library. On my x86_64 host, note that it has both the x86_64 and i686 versions of the ncurses packages installed: $ rpm -qa | grep curses ncurses-devel-5.9-13.20130511.el7.i686 <=== ncurses-5.9-13.20130511.el7.x86_64 ncurses-libs-5.9-13.20130511.el7.i686 <=== ncurses-libs-5.9-13.20130511.el7.x86_64 ncurses-base-5.9-13.20130511.el7.noarch ncurses-5.9-13.20130511.el7.i686 <=== ncurses-devel-5.9-13.20130511.el7.x86_64 $ And for looking at dumpfiles, there are a few other required packages, listed here in the crash.spec file: BuildRequires: ncurses-devel zlib-devel lzo-devel bison snappy-devel A 32-bit version of the "bison" package doesn't seem to be required for the build, but for the 3 potential types of compression used by makedumpfile for creating compressed kdumps, I have the zlib, lzo and snappy packages installed: $ rpm -qa | grep -e ncurses -e bison -e zlib -e lzo -e snappy | grep i686 ncurses-devel-5.9-13.20130511.el7.i686 ncurses-libs-5.9-13.20130511.el7.i686 snappy-devel-1.1.0-3.el7.i686 lzo-2.06-8.el7.i686 zlib-devel-1.2.7-17.el7.i686 lzo-minilzo-2.06-8.el7.i686 zlib-static-1.2.7-17.el7.i686 ncurses-5.9-13.20130511.el7.i686 zlib-1.2.7-17.el7.i686 snappy-1.1.0-3.el7.i686 lzo-devel-2.06-8.el7.i686 $ The lzo and snappy libraries are only required if you build the upstream crash sources with "make lzo" and/or "make snappy". But you will need 32-bit zlib packages installed. Dave

Hi Dave,

Thank you for your quick answer !

After installing ncurses for 32 bits architecture no more issue !

For ubuntu : sudo apt-get install lib32ncurses5-dev
Then same issue for lz but same solution : sudo apt-get install lib32z1-dev
