Hello @Greenscreen23. Apologies, but I am currently unable to do any work on this at the moment. I will disown the package so that you or someone else can update it.

Hey :) I tried building it and got an error because the return type of random was int in ns and long int in the stdlib. I've created a patch to fix an issue in configure that caused this, you can add it to the list of patches if you want.

I've rarely worked with autoconf, so feel free to tell me if I'm doing something wrong. I did not fully regenerate the configure file, because my autoconf did a lot of changes that did not seem necessary.

@qrwteyrutiyoup I can confirm that 2.35-9 builds correctly. Tested on two separate installations.

@aetherherne: could please you try 2.35-9?

This kept failing to build with gcc12, so I installed gcc5 from the AUR. After doing this I also added '!buildflags' to the PKGBUILD options array, and changed build() to:

build() {
  cd "${srcdir}"/"${pkgname}"-"${pkgver}"
  export CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fexceptions \
             -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security"
  export CXXFLAGS="$CFLAGS -Wp,-D_GLIBCXX_ASSERTIONS"
  export LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"
  export LTOFLAGS="-flto=auto"
  ./configure --prefix=/usr --with-tclcl=/usr/lib/tclcl --enable-static CC="gcc-5" CXX="g++-5"
  make
}

If you get error like: mac/mac-802_11Ext.h: In member function ‘u_int32_t PHY_MIBExt::getHdrLen11()’: mac/mac-802_11Ext.h:176:19: error: expected primary-expression before ‘struct’ mac/mac-802_11Ext.h:176:41: error: ‘dh_body’ was not declared in this scope mac/mac-802_11Ext.h:176:51: error: ‘offsetof’ was not declared in this scope open that file and add #include <cstddef> to the header files.

Please edit the PKGBUILD and add all the dependencies such as otcl tcl84 tk84 and so on, thanks

When I try to build, I get a compile error: tools/ranvar.cc: in member function `virtual double gammarandomvariable::value()': tools/ranvar.cc:219:70: error: cannot call constructor `GammaRandomVariable::GammaRandomVariable' tools/ranvar.cc:219:70: error: for a function-style cast, remove the redundant `::GaammaRandomVariable' make: *** [tools/ranvar.o] Error 1 ns make failed This is because GCC 4.5 does not like the X::X() style construct used in the NS2 source code and instead prefers the X() construct (according to http://forums.fedoraforum.org/archive/index.php/t-254937.html). Applying shadyabhi's patch solves the issue for me.

@shadyabhi Are you sure this wouldn't break the functionality?

I successfully compiled after few changes. Author pls add this patch to PKGBIULD http://dl.dropbox.com/u/7728421/ns2.patch
