Re: gcc bug: ___gxx_personality_v0 undefined

I am trying to test, but I have difficulties with autotools. cygwin has different versions of these tools and they conflict with each other. I decided to uninstall cygwin autotools and compile them from source (the requested versions as in NEURON's Latest Advances ). after running ./build.sh I confi...

Re: gcc bug: ___gxx_personality_v0 undefined

What I don't know is whether you were able to use the configure statements I indicated above to make a working version. i.e no python and no mpi and no flags other than the ones I indicated. I can compile successfully with ./configure --prefix=`pwd` CC=gcc-4 CXX=g++-4 LDFLAGS='-Wl,--enable-auto-imp...

Re: gcc bug: ___gxx_personality_v0 undefined

Were you able to reproduce my successful build? i.e after 'make mswin' you can execute c:/marshalnrn/nrn/bin/nrniv double clicking on the c:/marshalnrn/nrn/bin/nrniv.exe (4.5 KB in size) --> leads to error message: "This application has failed to start because nrniv.dll was not found.

Re: gcc bug: ___gxx_personality_v0 undefined

Finally, I find a way to compile at least with gcc-3: the problem was that the programmers considered the default directory of libraries is in "/etc/lib/gcc" but in my unmodified fresh install of cygwin they are in "/lib/gcc/(version)". So I changed the ~/neuron/nrn/src/mswin/nrnsygso.sh.in as hines...

Compile windows binary in linux

The src compiles very fast in linux and you have a bit more freedom than cwgwin. Is it possible to compile windows binary in linux to have a fair neuron benchmark between linux and win xp?

I was trying to compile neuron 7.1.333 with the latest cygwin with gcc-4 and g++-4 as compiler but I repeatedly have seen the error make nrniv.exe ../ivoc/nrnmain.o:nrnmain.cpp:(.eh_frame+0x11): undefined reference to `___gxx_personality_v0' please see http://www.cocoabuilder.com/archive/message/coc...

Re: compile neuron with intel compiler for linux?

after working full-time for more than 4 days, trying to know what compilers with which kernel flags and configurations would provide best performance in neuron for me, I have tried intel compiler and the that time I found intel compilers more than 100% faster in single thread mode with cache effect ...

Re: compile neuron with intel compiler for linux?

Please tell us the relative speed up when you use
cvode_cache_efficient(1)
Neuron runs faster when activating the cache efficacy, howere the relative speedup is about 10-15% in this case.

PS: I am using exactly the same version of icc.
