>Description:
building hdf-4.2r4, pkgsrc-2016Q4:
... -MD -MP -MF .deps/main.Tpo -c -o main.o main.c
main.c: In function 'main':
main.c:64:17: warning: implicit declaration of function 'getopt' [-Wimplicit-fun
ction-declaration]
while ((c = getopt(argc, argv, "bcfno:")) != EOF)
^
And then later:
tab.o -MD -MP -MF .deps/ncgentab.Tpo -c -o ncgentab.o ncgentab.c
In file included from ./ncgen.y:681:0:
./ncgen.l: In function 'yylex':
./ncgen.l:35:5: warning: implicit declaration of function 'yyerror' [-Wimplicit-
function-declaration]
yyerror("string too long, truncated\n");
^
./ncgen.y: At top level:
./ncgen.y:685:1: warning: return type defaults to 'int' [-Wimplicit-int]
yyerror(s) /* called for yacc syntax error */
^
./ncgen.y: In function 'yyparse':
./ncgen.y:539:11: warning: implicit declaration of function 'nctype' [-Wimplicit
-function-declaration]
nctype(valtype));
^
and finally:
libtool-fortran: link: gcc .. -o .libs/hdfncgen ...
ncgentab.o: In function `yylex':
ncgentab.c:(.text+0x1878): undefined reference to `yywrap'
collect2: error: ld returned 1 exit status
After I added "-lfl" to $LIBS in the build environment, the problem
disappeared.
