Hi,
woking on a W7(64)bit system, I updated my toolchain with Sourcery
CodeBench Lite 2012.09-63. Then I created a library from ecos using
these tools and ecos Configuration Tool 3.net (April 25 20:35:09).
However, when compiling (within eclipse cdt juno) my little
ustl-exercise (see attachment)
I get the following log:

16:58:36 **** Rebuild of configuration Debug for project ustl_1 ****

reference to `_impure_ptr'
collect2.exe: error: ld returned 1 exit status

16:58:37 Build Finished (took 1s.139ms)

Does anyone have good advice? Thank you.

==========================================
Ok, meanwhile I found an answer using google ecos _impure_ptr as search 
term.

I simply have to add the line:

void *_impure_ptr;

to my source and it builds.
