[Gretl-devel] Failed compiling on ubuntu 14.04

Hi all, I am trying to compile gretl  on ubuntu 14.04. This worked 4 months ago without any problem using the following "configure"-options: ./configure \         --prefix=$HOME/software/gretl \         --disable-gnuplot-checks \         --disable-gnuplot-3d \         --with-odbc --with-ODBC-prefix=${ODBC_DRIVER} At some compilation failed, however. The errors I get are: <compilation> ware/gretl/lib\" ../lib/src/dataset.c  -fPIC -DPIC -o .libs/dataset.o ../lib/src/bhhh_max.c: In function ‘bhhh_numeric’: ../lib/src/bhhh_max.c:37:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘Lval’      double * restrict Lval = L->val;                        ^ ../lib/src/bhhh_max.c:37:23: error: ‘Lval’ undeclared (first use in this function) ../lib/src/bhhh_max.c:37:23: note: each undeclared identifier is reported only once for each function it appears in ../lib/src/bhhh_max.c: In function ‘bhhh_max’: ../lib/src/bhhh_max.c:148:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘delta’      double * restrict delta = NULL;                        ^ ../lib/src/bhhh_max.c:148:23: error: ‘delta’ undeclared (first use in this function) ../lib/src/bhhh_max.c:149:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘ctemp’      double * restrict ctemp = NULL;                        ^ ../lib/src/bhhh_max.c:149:23: error: ‘ctemp’ undeclared (first use in this function) ../lib/src/bhhh_max.c:150:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘grad’      double * restrict grad;                        ^ ../lib/src/bhhh_max.c:150:23: error: ‘grad’ undeclared (first use in this function) </compilation> Does anybody have an idea how to deal with it? Are there any compilation parameters which I could try? Thanks, Artur
