build error : c++config.h not found

[epifanio]

cmake seems not able to find c++config.h

a locate c++config.h shows it is here :

/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../include/c++/4.7/iostream:39:10: fatal error: 'bits/c++config.h' file not found

(linux 64bit - ubuntu 13.04)

error temporary fixed with a sim link in /usr/local/include :

sudo ln -s /usr/include/x86_64-linux-gnu/c++/4.7/bits /usr/local/include/

And when exactly does this happen?

[epifanio]

from a fresh pywt checkout :

• git clone pywt
• cd pwt
• mkdir build
• cd build
• ccmake ..
  • configure
  • generate
• make Scanning dependencies of target python_dump [ 2%] Building CXX object introspection/CMakeFiles/python_dump.dir/main.o In file included from /home/epi/dev/src/pywt/introspection/main.cc:3:0: /usr/include/c++/4.7/iostream:39:28: fatal error: bits/c++config.h: No such file or directory compilation terminated. make[2]: * [introspection/CMakeFiles/python_dump.dir/main.o] Error 1 make[1]: * [introspection/CMakeFiles/python_dump.dir/all] Error 2 make: *\ [all] Error 2

(i removed the previous sim.link)

That looks like a bad compiler installation on ubuntu 13.04. What compiler are you using?

google links me to this: https://bugs.launchpad.net/ubuntu/+source/clang/+bug/1095357 but that talks about clang.

[epifanio]

gcc --version gcc (Ubuntu 4.7.2-22ubuntu1) 4.7.2

p.s. can be of any help, if i switch to a 12.04 version, i'm on osx using VM's

[wdu]

I developed on OSX (with portage gcc compilers for Wt/boost, clang for python_dump) and ubuntu 12.04.2 LTS

• i'm switching to a 12.04 version, i'll follow the previouse steps and i'll report here.
• in the meintime i'm on osx where i built llvm and clang, now building wt from git (i'm using xcode and homebrew to satisfy dependencies)
