Hello-
I am an engineer in HP and recently (1/11/89) attempted to build scheme on
an HP-UX version 7.0 operating system. As a result of various standards
conformance requirements, including ANSI C conformance, the current code
will abort with C compile time errors from mismatched type declarations
of certain system functions such as fread, fwrite, geteid, lseek, and others.
The first two lines of RCS.log from my scheme package are:
file: compiler/fgopt/desenv.scm; revision: 4.3
date: 89/07/12 00:14:16 GMT; author: cph; state: Rel
A simple solution has been provided by HP that works nicely with your
build automation. By adding the following line to your CFLAGS in your
makefile you will avoid the compile errors:
-D_CLASSIC_POSIX_TYPES -D_CLASSIC_ANSI_TYPES \
The resulting CFLAGS definition would then be:
CFLAGS = -O -Dspectrum \
-D_CLASSIC_POSIX_TYPES -D_CLASSIC_ANSI_TYPES \
-DCOMPILE_HISTORY $(MACHINE_SWITCHES)
This will not have any affect on prior HP-UX 7.0 systems and should provide
for transparent compatibility between prior 7.0 and beyond releases.
