I should maybe add that on this system I was already running a version of graph-tool compiled from source (2.14dev, I think) which I wanted to update. -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...

I have decided to delete the files I had and do it from scratch again. To start with I am running git clone gitlab@git.skewed.de:count0/graph-tool.git I am then executing autogen.sh. This returns the following: libtoolize: putting auxiliary files in `.'. libtoolize: linking file `./ltmain.sh' libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'. libtoolize: linking file `m4/libtool.m4' libtoolize: linking file `m4/ltoptions.m4' libtoolize: linking file `m4/ltsugar.m4' libtoolize: linking file `m4/ltversion.m4' libtoolize: linking file `m4/lt~obsolete.m4' libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. configure.ac:22: installing './compile' configure.ac:18: installing './config.guess' configure.ac:18: installing './config.sub' configure.ac:20: installing './install-sh' configure.ac:20: installing './missing' src/graph/Makefile.am: installing './depcomp' src/graph_tool/Makefile.am:3: installing './py-compile' configure.ac:39: error: possibly undefined macro: PKG_INSTALLDIR If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. I can then run the configure file that it has generated but is this an error that I would need to fix first? If I run configure it seems to happily run to the end. The only on-screen message that sticks out at me as being odd is: ./configure: line 16350: PKG_INSTALLDIR: command not found If I read the config.log (attached config.log <http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/file/n4026818/config.log> ) though I find a number of error messages largely revolving around ac_nonexistent.h, such as: conftest.c:11:28: fatal error: ac_nonexistent.h: No such file or directory #include <ac_nonexistent.h> and: conftest.c:54:26: fatal error: minix/config.h: No such file or directory #include <minix/config.h> Does anybody know what I need to do about these?

You need to install pkg-config.

It seems to already be installed. Running sudo apt-get install pkg-config tells me that the latest version is already installed. Running dpkg -l pkg-config returns: dpkg -l pkg-config Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-=====================================================-===============================-===============================-=============================================================================================================== ii pkg-config 0.26-1ubuntu4 amd64 manage compile and link flags for libraries -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...

Posting on Stackoverflow (http://stackoverflow.com/questions/40427879/graph-tool-autoconf-configure-ac... ) I got the answer that there might be an issue with the pkg-config version on Ubuntu 14.04. Somebody else reported a similiar problem (http://redmine.audacious-media-player.org/issues/248) where it looks like it may have been "solved" by commenting out the line containing PKG_INSTALLDIR. Would something like that be possible here too as a work-around? -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...

Happy to give it a shot though have absolutely no clue what I am doing here. I will simply comment out line 39 in configure.ac and see what happens. What does the line do? In your opinion, will it cause problems somewhere else down the line that won't be aparent during compilation? (i.e. if it could lead to incorrect results when using graph_tool I'd rather not mess with it.) -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...

Alas, that did not solve the problem.

The error messages about conftest.c:11:28: fatal error: ac_nonexistent.h: No such file or directory #include <ac_nonexistent.h>

and

conftest.c:54:26: fatal error: minix/config.h: No such file or directory #include <minix/config.h>

in config.log persist but autogen.sh runs without any errors.

As I already explained, these are not errors.

Running make still eventually throws the error "graph_triangulation.cc:55:61: fatal error: CGAL/Periodic_3_Delaunay_triangulation_traits_3.h: No such file or directory"

This is completely unrelated to any of this. It probably just means that your cgal version is too old. Some modifications were made recently in graph-tool to allow compilation with newer cgal that possibly have broken compatibility with older versions. I will investigate. -- Tiago de Paula Peixoto <tiago@skewed.de>

Hi Claudio, Alas, Ubunutu 14.04 only has CGAL4.2 in Launchpad so that probably won't work without compiling CGAL from scratch I would guess.
