* If NIX_DEBUG is turned on (set to "1"), autoconf configure scripts
|
|
may fail to find the correct preprocessor:
|
|
|
|
checking how to run the C preprocessor... /lib/cpp
|
|
|
|
|
|
* When building gcc using a Nix gcc, generated libraries link against
|
|
the libraries of the latter:
|
|
|
|
$ ldd /nix/store/3b1d3995c4edbf026be5c73f66f69245-gcc-3.3.3/lib/libstdc++.so
|
|
...
|
|
libgcc_s.so.1 => /nix/store/1f19e61d1b7051f1131f78b41b2a0e7e-gcc-3.3.2/lib/libgcc_s.so.1 (0x400de000)
|
|
(wrong! should be .../3b1d.../lib/libgcc_s...)
|
|
...
|
|
|
|
|
|
* Subtle problems can occur if the Nix store directory or one of its
|
|
parents is a symlink. E.g., purity checks can barf:
|
|
|
|
impure path `/data/nix/store/099cd9aee7d056a9922fd6dd116a3f5c-gcc-3.3.3/bin/../lib/gcc-lib/i686-pc-linux-gnu/3.3.3/crtbegin.o' used in link
|
|
|
|
(This happened because /nix was a symlink to /data/nix.) Maybe we
|
|
should disallow this entirely, since, exactly because it is
|
|
perfectly legal for a builder to expand a symlink, we can end up
|
|
with derivates referring to paths that existed in the build
|
|
environment but not in the target environment.
|
|
|
|
Disallowing this can be highly inconvenient, since it makes it
|
|
harder to move the Nix store to a different file system. (On Linux,
|
|
`bind' mounts can help here.)
