[ECOS] ECOS build/config problems under Sparc Solaris 2.5.1

[Mike MacMillan]

Hello,

I am having build/config problems of ECOS host tools on solaris 2.5.1.

I am running top-level configure script to supposedly build ecosconfig 
command line tool.
The following output is displayed:

checking host system type... sparc-sun-solaris2.5.1
checking for a BSD compatible install...
/export/home/mjm1431/ecos/ecos-1.3.1/to
ols/src/install-sh -c

checking whether the C compiler (gcc  ) works... no

Has anyone tried to do this on a solaris machine?
Any suggestions are welcome!

Thanks

Thank you!
