[Nix-dev] Problems building installation CD on Debian etch x86_64

[Steve Roggenkamp]

Thanks for responding.

Not a bad idea, but curl is already installed on the machine:

skr at roggen:~/Software/nix-0.12pre13257$ dpkg -l | grep curl
ii  curl                                7.15.5-1etch1         Get a file 
from an HTTP, HTTPS, FTP or GOPHE
ii  libcurl3                            7.15.5-1etch1         
Multi-protocol file transfer library


The problem appears to be in nix-build.  It appears the following C++ 
code in src/libstore/build.cc generates the error:

...
void DerivationGoal::startBuilder()
{
    startNest(nest, lvlInfo,
        format("building path(s) %1%") % 
showPaths(outputPaths(drv.outputs)))
   
    /* Right platform? */
    if (drv.platform != thisSystem)
        throw BuildError(
            format("a `%1%' is required to build `%3%', but I am a `%2%'")
            % drv.platform % thisSystem % drvPath);
...

What's somewhat surprising is that it appears the curl derivation 
defines "system" correctly:

/nix/store/n0j98b0464xc2n5pchzqh7hzmlvh240v-curl.drv:

Derive([...,("system","i686-linux")])

I haven't followed the code that reads the derivation to set the 
internal variables in nix-build.
