Bug ID: 241710
Summary: please increase ARG_MAX
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: b...@freebsd.org

I'm trying to upgrade the port french/aster to the latest stable
release. This is a complex port: it has no Makefile (in the upstream
tarball, but of course there is a Makefile for the port), and it uses a
combination of setup.py (Python) and a bundled waf.
At this point, it builds, but the latest step (linkage) fails with the
following message:
gfortran9: fatal error: cannot execute
'/usr/local/libexec/gcc9/gcc/x86_64-portbld-freebsd12.0/9.2.0/collect2':
execv: Argument list too long
Yes, linkage is done by gfortran, in a classical way:
gfortran9 (some -Wl parameters) (a very long list of object files .o) (a
list of several libraies with their paths)
but the problem is not caused neither by gfortran nor by the final
linker: if I execute the same command line manually from my shell, it
succeeds and the aster program is built.
So I guess that the problem is caused partly by the arguments list, but
also by the environment variables brought by the build system.
On my machine, `getconf ARG_MAX' returns 262144.
There's a sysctl kern.argmax, but it's read-only and initialized to ARG_MAX.
On PR 208154, for the same problem with Libreoffice, a work-around was to
disable-mergelibs. I'll try to apply the same with Code_Aster, but it's not
that easy with their build system (no configure).
Anyway, it would be a good thing to increase this limit, as other OSes do.
