making toolchain fails

[!gm]

Hi, because I need the swftools http://www.swftools.org I want to build it via the wl500g-repo openwrt buildroot. (thx ryzhov_al)

http://code.google.com/p/wl500g-repo.../trunk/INSTALL
http://code.google.com/p/wl500g-repo...trunk/Makefile

but instead of just make - at first I need to make .toolchain_installed
(I'll do the Makefile steps manually, because of integrating the swftools via this guide: http://wiki.openwrt.org/doc/devel/packages)

the build-system is an ubuntu-virtual machine

ok, a title says the make of toolchain fails:

Build dependency: Please install ncurses. (Missing libncurses.so or ncurses.h)
Build dependency: Please install zlib. (Missing libz.so or zlib.h)

uhmm, I don't know, whats wrong, because I allready have the ncurses and zlib developer-libs:

gm@ubuntu:~/openwrt/rtn$ sudo apt-get install libncurses-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'libncurses5-dev' instead of 'libncurses-dev'
libncurses5-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

and

gm@ubuntu:~/openwrt/rtn$ sudo apt-get install libz-dev
Reading package lists... Done

Reading state information... Done
Note, selecting 'zlib1g-dev' instead of 'libz-dev'
zlib1g-dev is already the newest version.

anyone an Idea?

anyone an Idea?

Ubuntu, yes? The same bug on my Ubuntu 11.10 x64.

Find ./toolchain-1.9.2.7-rtn-r3988/src/include/prereq-build.mk file and fix these lines:

...
define Require/ncurses
        echo 'int main(int argc, char **argv) { initscr(); return 0; }' | \
                echo -include ncurses.h -x c -o $(TMP_DIR)/a.out -lncurses -
endef

$(eval $(call Require,ncurses, \
        Please install ncurses. (Missing libncurses.so or ncurses.h) \
))


define Require/zlib
        echo 'int main(int argc, char **argv) { gzdopen(0, "rb"); return 0; }' | \
                echo -include zlib.h -x c -o $(TMP_DIR)/a.out -lz -
endef

Yes, i know its dirty hack, but works. I have no time to fix toolchain buildroot script.

BTW, toolchain buildroot is taken from OpenWRT too^)

To fix it we must know exact error message, can you post it?

Just execute following command in default shell (bash??):

echo 'int main(int argc, char **argv) { initscr(); return 0; }' | \
gcc -include ncurses.h -x c -o /tmp/a.out -lncurses -

the error

/tmp/ccbNsdgJ.o: In function `main':
:(.text+0x10): undefined reference to `initscr'
collect2: ld returned 1 exit status

I ended up with "echo 1", since I knew I had everything correctly installed on my mint box

It means that libncurses.so library cannot be found by gcc
Where is it located? OpenSUSE store it in /usr/lib (/usr/lib64)

Is library contains initscr():

readelf -s libncurses.so | grep initscr

?

[wpte]

yeah, that's the weird thing...
I've had other problems with finding libraries on previous versions of ubuntu's gcc, like libusb.

The current version I have:

gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1

libncurses.so is on my 64bit machine just in /lib/

readelf -s /lib/libncurses.so.5 | grep initscr
   399: 000000000000c6d0   179 FUNC    GLOBAL DEFAULT   11 initscr

the packages I use: http://packages.ubuntu.com/search?ke...ic&section=all
you can just open the deb files with an archive manager

In the end, all other programs I've compiled so far, including some other toolchains for my uni projects did find ncurses without any problem
