Re: [PATCH] Fix build of guile-3.0 trunk with gcc-8 on hpux11.11

[Massimiliano Gubinelli]

Hi John,

 could maybe be a bug with the Boehm-gc? I had some recent issues compiling Guile 2.2.7 in Haiku and discovered that there is a new version (8.1.0, next release development)  of the GC here

https://github.com/ivmai/bdwgc

which has some changes, in particular certain conditional compilations related to HP/UX, see e.g. lines 2708, 3093, ... here:

https://github.com/ivmai/bdwgc/blob/master/os_dep.c

Maybe you could try to link this new version and see if the problem with the test persist.

Best

Massimiliano

The following change fixes the build of guile-3.0 using gcc-8 on hpux11.11.
There are three issues addressed:

1) The printf function does not support %zu.  Since all the type sizes are small,
we can use %u and cast the sizeof results to unsigned int.

2) HP-UX 11.11 does not have readdir64 or readdir64_r.  The change adds back the
checks for readdir64 and readdir64_r.  I added support for readdir64 similar to that
for readdir64_r to gen-scmconfig.c and syscalls.h.

3) I needed to link libguile against gcc's libatomic. I don't have a configure fix yet.
So, I export "LIBS=-latomic" in my guild to get gcc's atomic routines. This fixed segmentation
fault building the texi documentation.

With these changes, all tests pass except the following:

Please install if okay.

Guile is part of the build and test environment that I use for gcc.  HP-UX is still the only
environment where we have a working 64-bit compiler.  It is needed to build the 64-bit linux
kernel.
