This fails because this command line does not include the option -Ae or -D_HPUX_SOURCE. One of these options is necessary, otherwise the HP-UX /usr/include/*.h files lack many POSIX declarations. In particular the one of 'environ'. The INSTALL file in gnulib recommends that for HP-UX cc not only the option "-Ae" but also "-D_XOPEN_SOURCE=500" should be used. > configure:27297: checking if environ is properly declared > configure:27325: cc -c -g -z +O2 -Ae -Wp,-H32768 ... conftest.c >&5 > cc: "conftest.c", line 41: error 1584: Inconsistent type declaration: > "environ". > cc: "conftest.c", line 45: error 1529: Cannot select field of non-structure. Here the 'environ' declaration is visible because "-Ae" is part of the command line. Maybe you have passed -Ae not as part of the CC variable but as part of CFLAGS or CPPFLAGS, and a particular Makefile rule ignores CFLAGS and CPPFLAGS. (Unlikely because the Makefile rules were generated by automake.) Or maybe you have overridden CFLAGS and/or CPPFLAGS somewhere? You shouldn't do that. Automake provides variables AM_CFLAGS and AM_CPPFLAGS that you can override instead. Bruno
