Hi!
I try to compile user space package, but unsuccesfully

When I've check whats wrong I've got:

[rusink@localhost ]$ mipsel-openwrt-linux-uclibc-gcc --std=gnu99 -E -I.  -Wall -c main.c >main.E
mipsel-openwrt-linux-uclibc-gcc: warning: environment variable 'STAGING_DIR' not defined
main.c:1:27: fatal error: libubox/uloop.h: No such file or directory
compilation terminated.

I've checked ~/openwrt/staging_dir/target-mipsel_r2_uClibc-0.9.33.2/usr/include/libubox/utils.h - is on place....

Who can tell where and how should I define 'STAGING_DIR?
I've tried to do it like:

export PATH=$PATH:~/openwrt/staging_dir/toolchain-mipsel_r2_gcc-4.6-linaro_uClibc-0.9.33.2/bin/ 
export STAGING_DIR=~/openwrt/staging_dir/toolchain-mipsel_r2_gcc-4.6-linaro_uClibc-0.9.33.2/

And than do make package/my_package/compile but got the same errors.

Hi rusink,

please try this:

 export STAGING_DIR=~/openwrt/staging_dir/

I'm wondering why this happened.
How did you set up the build environment?
In the mean time, do try tl71's solution.
My only concern is what else is broken.

I try to compile programm which isn't in openwrt trunk. It's new small manager for QMI modems by nbd. -git://nbd.name/uqmi.git
So I've made Makefile (using cmake.mk rules). but I can't hook up header from libubox. (which are already in ~/openwrt/staging_dir/target-mipsel_r2_uClibc-0.9.33.2/usr/include/libubox ). I can't compile programm in a result.
For example I've got :

openwrt/build_dir/target-mipsel_r2_uClibc-0.9.33.2/uqmi-r-0.0.1/qmi-message.h: In function 'tlv_data_len':
/openwrt/build_dir/target-mipsel_r2_uClibc-0.9.33.2/uqmi-r-0.0.1/qmi-message.h:88:2: error: implicit declaration of function 'le16_to_cpu' [-Werror=implicit-function-declaration]

When I've checked & got that answer from gcc.

So, I've no idea how to solve it yet.

P.S. I gess. I've should start ' export STAGING_DIR=~/openwrt/staging_dir/' befor checking main.c

[rusink@localhost uqmi-r-0.0.1]$ export PATH=$PATH:~/openwrt/staging_dir/toolchain-mipsel_r2_gcc-4.6-linaro_uClibc-0.9.33.2/bin
[rusink@localhost uqmi-r-0.0.1]$ export STAGING_DIR=~/openwrt/staging_dir/
[rusink@localhost uqmi-r-0.0.1]$ mipsel-openwrt-linux-uclibc-gcc --std=gnu99 -E -I.  -Wall -c main.c >main.E
[rusink@localhost uqmi-r-0.0.1]$

It is a pain, but if you follow the full build install (http://wiki.openwrt.org/doc/howto/buildroot.exigence) and then follow the instructions for crosscompiling (http://wiki.openwrt.org/doc/devel/crosscompile) that might help

Thanks. But I'm afraid it's not exactly what I need. Look:

[rusink@localhost ~]$ cd '/home/rusink/openwrt/build_dir/target-mipsel_r2_uClibc-0.9.33.2/uqmi-r-0.0.1' 
[rusink@localhost uqmi-r-0.0.1]$ export PATH=$PATH:/home/rusink/openwrt/staging_dir/toolchain-mipsel_r2_gcc-4.6-linaro_uClibc-0.9.33.2/bin
[rusink@localhost uqmi-r-0.0.1]$ export STAGING_DIR=~/openwrt/staging_dir/
[rusink@localhost uqmi-r-0.0.1]$ mipsel-openwrt-linux-uclibc-gcc
mipsel-openwrt-linux-uclibc-gcc: fatal error: no input files
compilation terminated.
[rusink@localhost uqmi-r-0.0.1]$ mipsel-openwrt-linux-uclibc-gcc --std=gnu99 -E -I.  -Wall -c main.c >main.E
main.c:1:27: fatal error: libubox/uloop.h: No such file or directory
compilation terminated.
[rusink@localhost uqmi-r-0.0.1]$ ls '/home/rusink/openwrt/staging_dir/target-mipsel_r2_uClibc-0.9.33.2/usr/include/libubox' 
avl-cmp.h  blobmsg.h       list.h   ustream.h      utils.h
avl.h      blobmsg_json.h  uloop.h  ustream-io.h   vlist.h
blob.h     list_compat.h   usock.h  ustream-ssl.h
[rusink@localhost uqmi-r-0.0.1]$

I've compiled libubox before, but compiler can't find this folder and hooks up needed *.h . Any ideas - why?

The discussion might have continued from here.
