@dreieck: I got the same error. To me, writing 1 byte into a region of size 0 looks like a scary bug, and the fact that LTO stumbles over it prompted me to try turning this off first. But the real issue and why it is not flagged without LTO merit further investigation.

I think somewhere an option -Wno-error=stringop-overflow= or just a general -Wno-error needs to be explicitly added to the gcc options (i.e. the CFLAGS/ CXXFLAGS). I get a -Werror=stringop-overflow= compilation error, and I have not set manually any -Werror option:

For me the problem was mitigated with adding

  CFLAGS+=' -Wno-error'
  CXXFLAGS+=' -Wno-error'
  export CFLAGS
  export CXXFLAGS

before the ./configure call.

Btw., I could compile it with LTO.

Thanks for maintaining!

Compilation fails with LTO enabled (which is the default, at least on my system). A workaround is to add the line "options=('!lto')" to the PKGBUILD.

Compiling on GCC 8.1+ is fixed, many thanks to @ThoSTe and sorry for the delay.

When I try to install the package I get a compile warning/error. (https://bbs.archlinux.org/viewtopic.php?id=247748)

This can be avoided by disabling Werror complie option in PKBUILD ./configure --prefix='/usr' --disable-Werror

tomxtobin: Thx, new package is up.

commented on 2013-03-15 16:19 (UTC)

Version 1.2.1 is available.

@tomxtobin: Thx! Package updated.

commented on 2012-12-19 03:03 (UTC)

Version 1.2 is available.

alucryd commented on 2012-11-15 15:17 (UTC)

Woops, bjnp needs to be executable.

commented on 2012-07-06 09:55 (UTC)

no more canon ...

commented on 2012-06-16 18:08 (UTC)

Never mind. It was easy enough to download it directly from Sourceforge and compile and install it.

I have tries this twice, today. "makepkg -s" results in: ==> Validating source files with md5sums... cups-bjnp-1.0.tar.gz ... FAILED ==> ERROR: One or more files did not pass the validity check! Is this package still good? Thanks.

Blubaur commented on 2011-07-07 12:19 (UTC)

does bjnp itself call 'pstoraster'? It seems to not exist in cups anymore, and when I try to print something I get Unable to execute /usr/lib/cups/filter/pstoraster: No such file or directory
