HI everyone! I have tried to install graph_tool by compiling source code.But for many times , it reports: virtual memory exhausted: Cannot allocate memory My PC has a 4G main memory and Intel i5 CPU.I thought 4G is enough.

Strange, 4GB should be enough. What GCC version are you using?

Then I tried to install by apt-get, and came up with a problem. I have already installed these library before, and versions are right.

graph-tool : Depends: libboost-iostreams1.42.0 (>= 1.42.0-1) but it is not installable Depends: libboost-python1.42.0 (>= 1.42.0-1) but it is not installable Depends: libboost-regex1.42.0 (>= 1.42.0-1) but it is not installable Depends: libcgal5 but it is not installable Depends: libpython2.6 (>= 2.6) but it is not installable Depends: libboost1.42-dev but it is not installable

Can anyone help me ?

What GNU/Linux distribution do you have, Debian or Ubuntu? What version?

By the way,how to use the public key ? I have tried "apt-key add signature.asc",but it reports: gpg: no valid OpenPGP data found.

The pgp server at skewed.de is currently down, so you probably just downloaded a 404 page. I'll fix this soon. In the meantime you can get the key from any other gpg server out there.

Hi,

I too get this error

make[4]: Entering directory `/graph-tool/build/src/graph/layout' CXX graph_sfdp.lo virtual memory exhausted: Cannot allocate memory make[4]: *** [graph_sfdp.lo] Error 1

Mine is also i5 with 4Gb mem.

I'll attempt to improve the memory usage during compilation of graph_sfdp.cc for the next release. In the meantime maybe you could try the clang compiler, which requires less memory to compile graph-tool.

Cheers, Tiago

Thanks for the hint, that did the trick for me as well.

I noticed that the temp file( ccwxyz.s) getting bigger and bigger before shooting this error. So i did a "make -n" in the directory were did this error is reported to get the exact compilation syntax and hand created the .lo file myself (maually) for that file alone.

After that I was able to proceed with compilation successfully and able to do examples. seems to a problem with the tools libtool, etc ... May be you can also try that way.
