Hello,
It looks like there were some unanswered questions not long ago regarding
problems building ns-2 on MacOSX 10.9 (Mavericks) with the newer Xcode 5. I
was just able to successfully build ns-2.35 on this platform with clang (llvm)
based Xcode 5 compiler with a couple of small tweaks. Here are some notes on
building the ns-2.35 ns _and_ nam executables on a Mac OSX 10.9 (Mavericks)
machine with the Xcode 5 llvm/clang compiler environment. Note that I did
_not_ use the "osx patch" that is available, but started with the generic
ns-allinone-2.35 tarball from the download site.
ns-2.35 Mavericks build notes
Starting with a fresh ns-allinone-2.35 tarball:
1) Run the ns-allinone "install" script
./install
(This builds Tcl and Tk until it fails on the otcl-1.14 build)
2) Build otcl-1.14 with different configure command:
cd otcl-1.14
./configure --with-tcl-ver=8.5.10 --with-tk-ver=8.5.10 CFLAGS="-framework
CoreFoundation"
make
cd ..
3) Build tclcl-1.20 with its default configure command
cd tclcl-1.20
./configure
make
cd ..
4) Modify a couple of source files and build ns with different configure
command:
a) Run configure
./configure --x-libraries=/usr/X11R6/lib --x-includes=/usr/X11R6/include
LIBS="-framework CoreFoundation -lstdc++.6" --with-otcl=../otcl-1.14
--with-tclcl=../tclcl-1.20 CFLAGS='-stdlib=libstdc++'
b) Edit the resultant "Makefile" and add "-stdlib=libstdc++" to CFLAGS macro
variable (It seems you should be able to make this happen somehow on the
configure command line, but I had no luck with it).
Note these two steps above set the clang compiler to use the "libstdc++" C++
template libraries, etc instead of the newer "libc++" library that clang
defaults to.
c) Edit the "linkstate/ls.h" file, line 137 to read:
void eraseAll() { this->erase(baseMap::begin(), baseMap::end()); }
Note adding the "this->" qualification to the call to "erase()" makes the
llvm/clang compiler happier
d) Edit the "common/TclAppInit.cc" file, deleting or commenting out line 240
which reads "extern MemTrace *globalMemTrace;"
e) Build ns
make ns
5) Build nam using the configure command:
./configure --x-libraries=/usr/X11R6/lib --x-includes=/usr/X11R6/include
LIBS='-framework CoreFoundation' --with-tcl-ver=8.5.10 --with-tk-ver=8.5.10
--with-otcl=../otcl-1.14 --with-tclcl=../tclcl-1.20
make nam
At this point you have the ns and nam executables for for your simulation
enjoyment. I also built the "dei80211" WiFi model without issue. I am sure
these changes can be incorporated into future ns releases for MacOSX 10.9
builds.
best regards,
Brian Adamson
