Bug ID: 7617
Summary: spamc cannot be build on Windows
Product: Spamassassin
Version: 3.4 SVN branch
Hardware: PC
OS: Windows 7
Status: NEW
Severity: normal
Priority: P2
Component: spamc/spamd
Assignee: dev@spamassassin.apache.org
Reporter: pu...@jam-software.com
Target Milestone: Undefined
Building spamc currently fails on Windows. This is caused by two issues:
1. There is a subtle bug in spamc/Makefile.win (see also bug #7393).
2. spamc/getopt.c is not POSIX-compliant.
Regarding 1.: The first line of the target for spamc/spamc.exe changes the
working directory. However, dmake (installed with Strawberry Perl 5.24) and GNU
make (gmake, installed with Strawberry Perl 5.28) spawn a sub-shell for each
command [^1][^2]. The change of directory thus only affects the sub-shell and
is "forgotten" immediately afterwards.
Regarding 2.: spamc/getopt.c uses function err from err.h, which is not part of
the POSIX standard [^3], and thus it is not availabe on Windows, neither
natively nor in MinGW.
I have fixes for these issues mostly ready. I will submit a patch, once I have
verified that no tests are negatively affected by this.
