MySQL Forums :: MySQL Proxy :: Install 0.6.0 by svn,configure error

That would be because you're using a non-existent c compiler.

Which platform are you using?

What you probably want is:
./configure \
LUA_CFLAGS="-I/directory/of/lua.h" \
LUA_LDFLAGS="-L/directory/of/liblua.so -llua"

Obviously you will need to replace /directory/of/lua.h etc with the actual path (just the directory, not the actual full path to the file)

That should work.

Or...

on a fresh copy, make sure you've installed pkg-config, the dev files for liblua (probably a package like lua-devel or lua-dev depending on your platform) then re-run autogen.sh.
