Configure complains about unary operator

[jvhaarst]

If I run configure, I get this error:

./configure: line 4899: test: !=: unary operator expected

That line is this one :
configure:if test $ac_cv_header_boost_unordered_unordered_map_hpp != yes; then

I tried to fix it with :
configure:if test "$ac_cv_header_boost_unordered_unordered_map_hpp" != yes; then

But then the configure script kept complaining about missing boost libraries, even if I downloaded the latest version, and placed in the source directory.

Without the fix it compiles fine, by the way.

Hmm, I can't tell why it isn't working. Your fix to the if test makes sense. Can you post your config.log file? (That contains the log output of ./configure.)

An alternative approach is to download and unpack the boost tarball in some completely unrelated directory and then add --with-boost=<boost-dir> to your ./configure command. (You can run ./configure --help to see the full list of options.) <boost-dir> should be the root-level directory of the unpacked tarball, I think (e.g. --with-boost=/home/joe/Downloads/boost_1_58_0).

The unary operator message is caused by a small bug in the configure.ac. I think I fixed it now (still need a new release for it though), but it shouldn't interfere with compiling the code. acd7106

However what Ben said is correct. Using --with-boost= is still needed if boost it is not in your default includes directory.

I just had a try on a newly installed Ubuntu 16.04 machine.
I did a git clone of the latest version.
Downloaded and unpacked the latest boost.

The unary operator message is still here, and after my "fix" from above, I do this:

./autogen.sh
./configure --prefix=$(pwd) —with-boost=/root/arcs/boost_1_63_0

And I get this weird result :

checking boost/graph/graph_traits.hpp usability... yes
checking boost/graph/graph_traits.hpp presence... yes
checking for boost/graph/graph_traits.hpp... yes
checking boost/graph/adjacency_list.hpp usability... yes
checking boost/graph/adjacency_list.hpp presence... yes
checking for boost/graph/adjacency_list.hpp... yes
checking boost/graph/undirected_graph.hpp usability... yes
checking boost/graph/undirected_graph.hpp presence... yes
checking for boost/graph/undirected_graph.hpp... yes
checking boost/graph/graphviz.hpp usability... yes
checking boost/graph/graphviz.hpp presence... yes
checking for boost/graph/graphviz.hpp... yes
configure: error: Requires the Boost C++ libraries, which may
	be downloaded from here: http://www.boost.org/users/download/
	The following commands will download and install Boost:
	cd /root/arcs
	wget http://downloads.sourceforge.net/project/boost/boost/1.58.0/1_58_0.tar.bz2
	tar jxf 1_58_0.tar.bz2
	cd -

The strange thing is that is seems to be able to find the boost libraries, yet still somehow complains about not being able to find them..

I also faced the config error ./configure: line 4899: test: !=: unary operator expected, and the make install failed as

@jvhaarst I apologize, I didn't test the 'fix' I made previously. I just pushed a fix 90f7ea7 and tested it now and it seems to be okay on my end. Let me know if you still have issues.

@conniecl This doesn't have anything to do with the previous error relative to boost. I think it is a gcc version issue that we need to resolve/update, though I'm pretty sure we have tested it with newer versions of gcc recently. For now, try and older version (4.4.7 mentioned in the readme) of gcc and we will fix it asap.

[conniecl]

@JustinChu Thanks for your adivise, I have changed the gcc to 4.47, it seems work well. And thanks you again

[jvhaarst]

@JustinChu I have just done a new test run, and your fixes work, I no longer see a unary operator warning and the boost libraries are used.
The compilation did fail as I hadn't installed zlib yet, but after that it went fine.

So all is well, but you might want to add zlib to the checks.

Thank you, @JustinChu!
