After upgrading gcc to 4.1.1 I'm having problems in compiling gretl on my amd64 machine. Here the error gcc -c -g -O2 -I.. -I../gui2 -DHAVE_CONFIG_H -I../lib/src -I/usr/include/gtk-2.0 -I/usr/lib64/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/libxml2 -I../plugin -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I../plugin/zipunzip -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I. -DUSE_GMP gretlzip.c -fPIC -DPIC -o .libs/gretlzip.o gretlzip.c:30:22: error: zipunzip.h: No such file or directory gretlzip.c: In function 'gretl_make_zipfile': gretlzip.c:46: error: 'ZIP_RECURSE_DIRS' undeclared (first use in this function) gretlzip.c:46: error: (Each undeclared identifier is reported only once gretlzip.c:46: error: for each function it appears in.) gretlzip.c: In function 'gretl_is_zipfile': gretlzip.c:52: error: 'zipinfo' undeclared (first use in this function) gretlzip.c:52: error: 'zinfo' undeclared (first use in this function) make[1]: *** [gretlzip.lo] Error 1 make[1]: Leaving directory `/usr/local/gretl/plugin' make: *** [plugin] Error 2 Did I miss anything?
