I get the same error with GCC 4.1.1 and glibc 2.4.

edit reedsolomon.cpp

and replace:
bool ReedSolomon

with:
template <> bool ReedSolomon

this helped for me

debian etch has a patch that probably fixes this:

When building 'par2cmdline' on amd64 with gcc-4.0,
I get the following error:

With the attached patch 'par2cmdline' can be compiled
on amd64 using gcc-4.0.

Same here with gcc 4.2.1, though the error message is shorter:

reedsolomon.cpp:54: error: too few template-parameter-lists

and lots of warnings for every file:

par1fileformat.h:41: warning: ignoring packed attribute because of unpacked non-POD field ‘MD5Hash PAR1FILEHEADER::controlhash’
par1fileformat.h:42: warning: ignoring packed attribute because of unpacked non-POD field ‘MD5Hash PAR1FILEHEADER::sethash’
par1fileformat.h:56: warning: ignoring packed attribute because of unpacked non-POD field ‘MD5Hash PAR1FILEENTRY::hashfull’

Thank you! This helped for me too. With this recommendation I compile par2 on Slackware 12.1.
