[Gretl-devel] Issues compiling gretl

Hi all, I wish all list-members a happy new year! I am trying to compile gretl on a naked Ubuntu 19.04 system but it fails due to some (I think so) compiler issues. The packages I've installed are: gcc autoconf automake cmake apt-utils \ libtool flex bison gcc-doc libc6-dev libc-dev gfortran \ gettext libglib2.0-dev libgtk3-perl libgfs-dev \ libpng-dev libxslt1-dev liblapack-dev libfftw3-dev \ libreadline-dev zlib1g-dev libxml2-dev libgmp-dev \ libcurl4-gnutls-dev libmpfr-dev git gnuplot imagemagick \ libjson-glib-1.0-0 libjson-glib-dev \ openmpi-bin openmpi-common I am pretty sure that further package is needed. However, I can't figure out which one(s). The make command yields the following error: <make> libtool: link: ( cd ".libs" && rm -f "reprobit.la" && ln -s "../reprobit.la" "reprobit.la" ) ../libtool --mode=link gcc -mavx -Winline -fopenmp -module -avoid-version -rpath /usr/local/lib/gretl-gtk2 -o json_get.la json_get.lo ../lib/libgretl-1.0.la -ljson-glib-1.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 libtool: link: ( cd ".libs" && rm -f "xml_get.la" && ln -s "../xml_get.la" "xml_get.la" ) ../libtool --mode=compile gcc -mavx -Winline -fopenmp -c -g -O2 -I.. -I../gui -DHAVE_CONFIG_H -I../lib/src -I/usr/include/libxml2 -I../plugin -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I../plugin/zipunzip -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -pthread -I/usr/include/json-glib-1.0 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/uuid -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I../plugin/libsvm -Wno-deprecated-declarations -I. mp_ols.c libtool: error: specify a tag with '--tag' make[1]: *** [Makefile:248: svmlib.lo] Error 1 make[1]: *** Waiting for unfinished jobs.... </make> Searching the web for the error message is not really helpful here. Does anybody have an idea what is missing? Artur
