[buildd-tools-devel] Bug#589658: schroot: configure.ac boost function header issue

[Zach Carter]

Package: schroot
Version: 1.4.2

In the fedora build system, the ./configure process fails with this error:

	configure: error: libboost_program_options (Boost C++ Libraries) is not installed, but is required by schroot


It doesn't seem to fail on my local build machine, but it does in the fedora build system.  I'm not sure what the difference could be, as the toolchain should be exactly the same.

The config.log shows this:

"...
| include <boost/program_options.hpp>
| int
| main ()
| {
| boost::program_options::variables_map::variables_map dummy()
|   ;
|   return 0;
| }
configure:18263: g++ -o conftest -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -
fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic   
conftest.cpp -lboost_program_options -lboost_system -lboost_regex -
lboost_program_options-mt >&5
conftest.cpp: In function 'int main()':
conftest.cpp:58:1: error:

not the type
conftest.cpp:58:54: error: expected ';' before 'dummy'
conftest.cpp:59:3: error: statement cannot resolve address of overloaded 
function
configure:18263: $? = 1
configure: failed program was:
...
"

At the suggestion of some other fedora developers, I made this change and now it works:
