hide_flag missing in web.h

[blut]

There is an issue when compiling with some default options for generic UNIX on ubuntu 14.04.4 LTS with gcc-6.2.0:
CC= gcc -O2
CFLAGS= -DGENERIC
GRAPH= xgraph.o
GRAPHLIB= -lX11

Error:
gcc -O2 -DGENERIC -c xgraph.c
xgraph.c: In function ‘xgraph_facet’:
xgraph.c:247:11: error: ‘struct webstruct’ has no member named ‘hide_flag’; did you mean ‘full_flag’?
if ( web.hide_flag && (t->color != CLEAR) && (t->color != UNSHOWN) )

The hide_flag is indeed missing from web.h. Apparently it got lost some time between 2.30 and 2.70

gcc -O3 -DLINUX -DOOGL -c xgraph.c
xgraph.c: In function ‘xgraph_facet’:
xgraph.c:247:12: error: ‘struct webstruct’ has no member named ‘hide_flag’; did you mean ‘full_flag’?

^~~~~~~~~
full_flag
Makefile:242: recipe for target 'xgraph.o' failed
make: *** [xgraph.o] Error 1

How to solve this?

Hi tanwi90,

So what I did to compile the version from Ken Brakke's webpage (the tar.gz unix version) was:
commented out the entire SET_PERM_SGLOBAL_NODE section in evalmore.c
in web.h added a line saying:
int hide_flag
in lexinit.c added a line saying:
web.hide_flag=1;
