Bug#772642: cpp-4.9: please support multiarch for the user search paths (CPATH, etc.)
Package: cpp-4.9
Version: 4.9.2-5
Severity: wishlist
cpp currently supports multiarch search paths for /usr/local and /usr,
but not for directories supplied via environment variables like $CPATH
and $C_INCLUDE_PATH. For instance, "cpp -v" gives:
/usr/local/include/x86_64-linux-gnu
/usr/local/include
[...]
/usr/include/x86_64-linux-gnu
/usr/include
and when adding the -m32 option:
/usr/local/include/i386-linux-gnu
/usr/local/include
[...]
/usr/include/i386-linux-gnu
/usr/include
But if I use CPATH=/home/vlefevre/include, I just get:
/home/vlefevre/include
Adding the other directory to $CPATH is not a good solution because
one doesn't always know the ABI (whether -m32 is present or not) in
advance, i.e. one doesn't know in advance which directory to add.
