### Running into error with 3.2 installation

Hello,

On the new version, I am running into trouble at the ./configure (with default options) and subsequent steps.

Code: Select all

user@user-Inspiron-3268:~/Downloads/polymake-3.2$./configure checking C++ compiler ... ok (g++ is GCC 5.4.0) checking C++ library ... ok (GNU libstdc++ 20160609, C++ 201402) determining architecture ... ok (x86_64) determining compiler flags ... ok CFLAGS= -march=native CXXFLAGS= -std=c++14 -march=native -ftemplate-depth-200 -fno-strict-aliasing -Wno-parentheses -fwrapv -fopenmp checking gmp installation ... ok checking mpfr installation ... ok checking boost installation ... ok checking libxml2 installation ... Could not find configuration program xml2-config for library libxml2. Probably you need to install development package for it; usually it is called libxml2-devel or similarly. If the library is installed at a non-standard location, please specify it in option --with-libxml2 ---- user@user-Inspiron-3268:~/Downloads/polymake-3.2$ make ninja -C build/Opt all make: ninja: Command not found Makefile:34: recipe for target 'all' failed make: *** [all] Error 127 ---- user@user-Inspiron-3268:~/Downloads/polymake-3.2$sudo make install [sudo] password for user: ninja -C build/Opt install make: ninja: Command not found Makefile:34: recipe for target 'install' failed make: *** [install] Error 127  I tried sudo apt-get install libxml2-dev as well as sudo apt-get install libxml2-devel as suggested by the ./configure command, but neither of these packages seem to be installable. Code: Select all E: Unable to locate package libxml2-devel Any help is appreciated. gawrilow Main Author Posts: 331 Joined: 25 Dec 2010, 17:40 ### Re: Running into error with 3.2 installation Your system lacks at least two packages, the first one is ninja-build (visible thanks to the message "ninja: Command not found"), the second one is in fact the development package for libxml2. The suggested name is just a hint. On Ubuntu 16.04 this package is called libxml2-dev, other Linux distributions may use other names, but they should have libxml2 in the name. I bet libxslt1-dev and both perl wrappers, libxml-libxml-perl and libxml-libxslt-perl, are missing on your computer as well. If your system is indeed a Ubuntu, please check the full requested package list on https://polymake.org/doku.php/howto/ins ... and_ubuntu .

Prior to this install, I had installed polymake under the "debian/ubuntu" distribution.

Code: Select all

sudo apt-get install polymake
But that does not seem to have 3.2 yet and has 3.0 still. With the previous (3.0), with typing polymake, I did not encounter the errors I am obtaining now.

Thank you.

### Re: Running into error with 3.2 installation

ppl, Singular, and soplex interfaces are optional for polymake, therefore the configuration process reported a success. On the page https://polymake.org/doku.php/external_software you'll find an overview of all optional interfaces together with links to the sites where you can download and install the missing third-party software , in case you really need them.

The JSON module is needed if you are going to interact with the polymake database, cf. https://polymake.org/doku.php/data . Unfortunately, we forgot to list the perl module on the installation page. To unblock yourself, please install the package libjson-perl.

### Re: Running into error with 3.2 installation

Yes, after installing that, running polymake gives no errors at startup.

Regarding ppl, in my earlier post on this forum, I experienced a problem instance of computing facets for a set of points for which ppl ran very quickly as compared to lrs.

See viewtopic.php?f=8&t=607

In the opening line of polymake, I do not see ppl but see lrs:

Is my failed installation of ppl in ./configure above the reason why ppl is not available?

### Re: Running into error with 3.2 installation

Yes, surely. Please check the log file build/bundled.log for messages explaining the failure reasons. When you have fixed the problem, repeat the configure and ninja install steps.

Please be aware that the polymake configuration script does not try to install ppl for you, neither any other third-party software. It merely checks for their presence and usability, then it enables or disables corresponding interfaces.

### Re: Running into error with 3.2 installation

Hi gawrilow,

Thanks for your help. I was able to uninstall 3.2 and am back with 3.0 where things were working better for me. When I have more time, I will install 3.2 and hopefully get it up and running.

### Re: Running into error with 3.2 installation

Well, you can surely choose which version to use, just be aware that the relationship between polymake and third-party packages has been the same for ages. If polymake 3.0 can find a ppl installation on your system then 3.2 will find at as well, and vice versa. So there must be another problem with your setup, independent from the current polymake version.

Anyway, triggered by your posts we updated the required package lists for Ubuntu and some other Linux distributions, which is good on its own right. Thanks for your patience!

### Re: Running into error with 3.2 installation

Just a short information regarding ppl:
Ubuntu 16.04 provides ppl version 1.1 while polymake 3.2 needs version at least 1.2.
So it does make sense that polymake 3.0 can work with the installed ppl but polymake 3.2 cannot.

### Re: Running into error with 3.2 installation

Just for info:

After I uninstalled 3.2 and installed 3.0 (by following instruction https://polymake.org/doku.php/howto/install) by simply running "sudo apt-get install polymake", it installs 3.0 with ppl.
