Package: lua5.1
Version: 5.1.4-6
Changeset 5.1.4-6)which introduced DEB_HOST_MULTIARCH for the
LUA_CPATH_DEFAULT in luaconf.h, like so:
#define LUA_CDIR2 LUA_ROOT2 "lib/" DEB_HOST_MULTIARCH "/lua/5.1/"
...
#define LUA_CPATH_DEFAULT \
"./?.so;" LUA_CDIR"?.so;" LUA_CDIR2"?.so;" LUA_CDIR3"?.so;"
LUA_CDIR"loadall.so"
#endif
The DEB_HOST_MULTIARCH is only set during the Debian build process, or
manually through the preprocessor. Since Lua packages are built with
debhelper, they include a well-formed LUA_CPATH_DEFAULT.
However, this change breaks the compilation of programs outside of
debhelper which embed Lua and rely upon LUA_CPATH_DEFAULT:
error: expected ')' before 'DEB_HOST_MULTIARCH'
A workaround is to set DEB_HOST_MULTIARCH manually (using
dpkg-architecture -qDEB_HOST_MULTIARCH), or construct ones own
LUA_CPATH_DEFAULT.
Since liblua5.1-0dev is architecture-specific, perhaps the build process
could insert the architecture into luaconf.h rather than depend on a
definition set in the package build process?
This is still present in the 5.1.4 series, as well as 5.1.5-1
