Hi GRASSusers

I tried to install GRASS4.1beta over this weekend without success.
Here is the tail of the GISGEN.out

/users/g41/src/libes/proj
  make -f OBJ.aux/make.rules

        rm -f OBJ.aux/PJ_aea.o
        cc -O -I/users/g41/src/include -DUSE_TERMIO -c PJ_aea.c
"PJ_aea.c", line 50: HUGE_VAL undefined
"PJ_aea.c", line 54: HUGE_VAL undefined
"PJ_aea.c", line 71: HUGE_VAL undefined
Make: *** Error: Update of `OBJ.aux/PJ_aea.o' terminated with exit code 1
Make: [line 152 in /users/g41/src/libes/proj/OBJ.aux/make.rules]

GISGEN failure at STEP: src/libes/proj

Could somebody tell me where the header file that define this HUGE_VAL. I
didn't have this problem in installing 4.0 on a Mac running A/UX.

HUGE_VAL is an ANSI standard macro defined in math.h (sect. 4.5, line 7,
page 112, X3.159-1989). Its usage is usually as a flag to indicate
failure to compute some type double value. I would personally yell at
the A/UX people about this but in the mean time you can patch with a
macro in projects.h with something like:

  #ifndef HUGE_VAL
  #define HUGE_VAL 1e100
  #endif

or some other suitably large value. HUGE_VAL is used in several other
spots in Rel.4 proj. Using GNU's gcc with their headers should also work.
Also check that there may be other compiler flags which will force
ANSI compliance---a lot of machines get confusing in this area.
