Thanks for the reply. Yes, I am aware what the the error itself is, but I was hoping this was a known issue, with perhaps a work-around to go with it. Looks like I'm out of luck on that front. The gcc3.3 series does build on solaris10, so a move to another series might be the way to go. However, when you have a legacy of commercial products to support, it's not always easy to upgrade to the latest and greatest :-) Best of luck, Dan -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of Ian Lance Taylor Sent: Thursday, July 06, 2006 2:34 AM To: Dan Keating Cc: gcc-help@xxxxxxxxxxx Subject: Re: Gcc3.2 build error on Solaris 10 "Dan Keating" <dan.keating@xxxxxxxxxxx> writes: > I'm having problems building gcc3.2 on a solaris 10 system.

Look at the two files in question: gcc-3.2/libstdc++-v3/libmath/mathconf.h, line 84 /usr/include/iso/math_c99.h, line 145 Most likely you will see conflicting types for nan. Since gcc 3.2 is four years old and completely unsupported, your best bet for fixing this would be to edit mathconf.h to match your system header file. Ian
