Hi there,

I am trying to cross compile ncurses for an arm-processor under uClinux. I have been having a lot of problems with that, and my last try was to install ncurses.5.4 under uClinux/uClibc 'casue when i selected the "ncurses-library support" option compiling the uClinux kernel (make menuconfig), it did not work (basically because the ncurses libraries were installed under glibc instead uClibc).

When i run a script (see below) to configure ncurses-5.4 i get the following error:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
./my-config.sh
Configuring NCURSES 5.4 ABI 5 (Wed Sep 14 17:36:37 CEST 2005)

checking for arm-elf-gcc... arm-elf-gcc
checking for C compiler default output... configure: error: C compiler cannot create executables
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Although i have tried different configurations of this script i have not yet succeeded. I would really be grateful if somebody can give me a hand.

p.s: my.config.sh

Hmm, here's a guess from the top of my head... Is the configure script trying to execute a sample program compiled with the cross-compiler?

BTW the '[ code ]' tags (without spaces) make code and output a lot easier to read.

A few months ago I was compiling, or trying to compile ncurses againsta uClib and was getting errors about 'not getting pthread version' or something similar.

I was following a step-by-step for building uSTEP -you might look for it as a reference

With this script i just wanted to configure the ncurses specifying basically the compiler and the flags that must be used in order to compile and link a program that uses the ncurses libraries. My intention is to execute a program based on ncurses after configuring ncurses and compiling uClinux in a proper way.

Regarding to the step-by-step for building uSTEP, i am afraid that i could not find that such a document, could you please tell me a little bit clearer where you found that document?

ncurses wouldn't compile against uClib -returned errors of:
'pthread version not found'
