Hello,

This is my first attempt trying to build OpenWrt on ubuntu.
The build stops at ncurses saying `error: C compiler cannot create executables`.

I did try the curses patch in ticket #19749, but it didn't help.

I tried commenting out these specific tests from ncurses' configure script, but then I get the error `*** No rule to make target 'libs'.  Stop.`

I'm building with gcc5, so I had to add `compiler-gcc5.h` as per this patch.

Am I doing something wrong?

You are doing it right, but you are missing NCurses.

Try this:

apt-get install -y subversion gawk ccache mercurial git-core build-essential libssl-dev libncurses5 libncurses5-dev unzip gawk zlib1g-dev

That should install NCurses as well as other dependencies you may need...

If not post back, I had troubles getting NCurses to install, I had to download all the DEB's manually and install it.

If solved please add "(solved)" to the topic name, thank you!

Cheers big_smile

Thanks for the suggestion @mys5droid.

I tried the `apt-get install` you suggested, but it didn't solve my problem.

Further, libncurses5 and libncurses5-dev are already the newest versions.
Only the following packages were actually installed - 

 git-core javascript-common libjs-excanvas mercurial mercurial-common

The build still stops at ncurses, same as before, with the same error in config.log: 

configure:1714: x86_64-linux-gnu-gcc -V </dev/null >&5
x86_64-linux-gnu-gcc: error: unrecognized command line option '-V'

Finally solved it, although I'm not exactly sure how.
I had to manually run configure and make from the ncurses source directory.

cd openwrt-trunk/build_dir/host/ncurses/
export CPPFLAGS="-P"
./configure
make

Then continued in the openwrt root directory with 

make V=s

Nice work... I wouldn't have figured that one out tongue

Odd, I never ran into that problem... I just ran make and it made all the required packages. It complained about ncurses, but all I had to do was that apt-get I pasted to you.

Anyways great job!

See ya around smile
