Problems building protoc-c on windows/cygwin

[mag...@goteb.org]

Hi, I am trying to build the C version of the protocol buffer tools on
windows/cygwin but get problems in the make phase.

To begin with I have built the normal c++ protobuf tools (2.0.3 rc2)
with
./configure --prefix=/usr
make
make check
make install

no problems there

Then I do the same for protobuf-c-0.8
./configure --prefix=/usr
make
here I run inte the problem, it seems like files are missing?

Thanks for any help!

Why rc2?  That's a release candidate build (like a beta).  You should use the official 2.0.3 release.

 

Then I do the same for protobuf-c-0.8
./configure --prefix=/usr
make

From the errors it looks like protobuf-c may already be implementing packed repeated fields, which were not in protobuf 2.0.3 but will be in 2.0.4.  You may have to use an older version of protobuf-c.  That's just my guess, though; you should probably contact the author of protobuf-c directly.

[Ivarsson, Magnus]

Hi, is there a specific forum for protobuf-c? I did not find it so how do I contact the author directly? I have added a comment on the wiki page but it does not feel like the correct forum.

 

Anyway, I forgot to mention that I can build it allright on a Linux platform so I guess the problem is cygwin related.

And this morning I also tried the protobuf-2.0.3 release, protobuf-c-0.8 and the protobuf-c-0.7 release, all with the same errors as before.

 

Any more ideas?

The author of protobuf-c is lahi...@gmail.com -- just e-mail him.

I think this is a fairly classic cygwin bug: not using enough $
(EXEEXT)'s in your Makefile(.am)s. The needed patch is likely:

-generated-code/test-full-cxx-output.inc: cxx-generate-packed-data
+generated-code/test-full-cxx-output.inc: cxx-generate-packed-data$
(EXEEXT)

(and one similar change)
(i will release a new protobuf-c w the fix once tested)
