Re: [boost] Error compiling a simple program using Multi_array of Variants with gcc 3.4.3 (but works on 3.2.3 - Opposite of my last email)

boost 1.31.1 and multi_array for variants

for g++ (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-42): No Errors

I just compiled your program with Cygwin G++ 3.4.4 using the Boost CVS. I suggest first upgrading your compiler and then, if that doesn't work, your Boost. -- Dave Abrahams Boost Consulting www.boost-consulting.com
