problem with ./configure script #18

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. uncompress  protobuf-c-0.10
2. execute ./configure
3. ./configure fails

What is the expected output? What do you see instead?
I expect a successfull operation message. I see next message:
configure: error:
ERROR:
protobuf test program failed to link:
perhaps you need to add -Llibdir to your LDFLAGS.

What version of the product are you using? On what operating system?
0.10 on Fedora core 5

Please provide any additional information below.

Finally I resolved the issue,
Checking the config.log I realized that libproto uses pthread and test program 
does
not  try to link against it, so I exported this variable:
"export LDFLAGS=-lpthread" 
before executing configure and all went right.
But, where is the problem?, in configure script or in protobuf library?.

This is a bug in the configure script. This was recently raised on the protobuf
mailing list: basically pthreads was always required, but until recently you 
could
get by, just by chance, without it.

ok, i've added -lpthread unconditionally to the build...  leaving open since 
i'm too
lazy to verify that that's the right thing to do... (e.g. on windows)

I saw the same problem on Leopard (10.5.8) and I had to add the lib directory 
path when compiling for 64-bit 
with the libraries in a non standard location.

i think you are supposed to add -pthread to CFLAGS if using gcc.

       -pthread
           Adds support for multithreading with the pthreads library.  This option 
sets flags for both the preprocessor and linker.

execute ./configure LDFLAGS=-lpthread

ERROR:

why?
