Hi Gautam
I cannot reproduce that isse on my Debian Squeeze using g++ 4.4.5.
What happens when you add a -Wall compile flag to the Makefile ?
I have confirmed that gcc-4.6.0 and the latest gcc-4.6.1 have this
problem. Also, I built gcc-4.5.3, it DOES NOT have any problems.
As for using the "-Wall" flag, i have copied the output below - it
shows some warning but nothing related to UNDEFs for VERSION_1 and
VERSION_MASK.
I suspect some new C++ standard rule must be in gcc-4.6.x series and
this may lead to name space issues. But I don't know the thrift stuff
well enough to quite figure this out in limited time I have spent on it.

Hi Gautam and all,
I have the same issue: when compiling a thrift client with g++ 4.6.1
(debian testing) and the latest thrift from the subversion, i get
messages about undefined references to VERSION_1 and VERSION_MASK
For example:
/usr/local/include/thrift/protocol/TBinaryProtocol.tcc:35: undefined
reference to
`apache::thrift::protocol::TBinaryProtocolT<apache::thrift::transport::TTransport>::VERSION_1'
I know this particular client was compiling correctly 1 year ago (with a
different gcc and thrift version).
But isn't it normal that the linker complains? since VERSION_1 and
VERSION_MASK are *declared* in TBinaryProtocol.h, but never *defined*.
I'm far from being a c++ expert, but i think that even if you're allowed
to declare a static const integral value in a class header, you're still
supposed to define it somewhere so that it exists in an object file?
as you cross-posted on both user and dev mailing list, i also cross-post
my answer, not knowing where a discussion may start.
regards,

Betreff: undefined references to VERSION_MASK and VERSION_1
When compiling the "cpp" example in "tutorial", i get:
CppServer.o
U
apache::thrift::protocol::TBinaryProtocolT<apache::thrift::transport::TTrans
p
ort>::VERSION_MASK
U
apache::thrift::protocol::TBinaryProtocolT<apache::thrift::transport::TTrans
p
ort>::VERSION_1
I am running on Fedora 15 w/ GCC/G++ 4.6.0. The ./configure and "make"
and "make install" had gone w/o errors (as far as I could tell.)
Any hints welcome. I tried to google this, but found nothing.
Gautam
