Subject: nmap: Build process isn't thread safe

Date: Mon, 17 Aug 2009 03:57:19 -0300

[Message part 1 (text/plain, inline)]

Package: nmap
Version: 5.00-1
Severity: minor

Hi!

nmap fails to build if built with more than one thread (using "-j2" in
DEB_BUILD_OPTIONS, for example).

See the attached pbuilder log for the errors when building the package with 2
threads.

Thank you!

Best regards,
Nelson

Thanks for the report.  Are you able to reproduce this with the
unmodified Nmap tarball (http://nmap.org/dist/nmap-5.00.tar.bz2) and
"make -j2" or -j4 or whatever?  I've been using -j4 on almost all my
Nmap builds for years and haven't encountered problems.

I looked at your attached log.txt, but it doesn't seem to show the
exact error.  It just finishes configure and then says:

Configuration complete.  Type make (or gmake on some *BSD machines) to compile.
touch configure-stamp
dpkg-buildpackage: error: debian/rules build gave error exit status 2
E: Failed autobuilding of package
I: unmounting dev/pts filesystem
I: unmounting proc filesystem
 -> Cleaning COW directory
  forking: rm -rf /var/cache/pbuilder/build//cow.24037

Cheers,

It builds fine.
It seems to be some race condition in debian/rules.
Replacing it with a new one (using the template that dh_make
generates), the package is built properly (even with -j4, that I use
for all the packages that I build).

I will see if I can track what is the problem.

Best regards,
Nelson
