我最近更新的GNAT编译器的新版本..我试图编译GNADE源（http://gnade.sourceforge.net/）阿达编译缺少亚基
是否有某种标志我需要设置或某种方式来调试呢？
我看到这个错误（当使用GNATPro 6.22下编译罚款）：
gnatmake -g -O0 -fstack-check -pipe -gnatE -gnatU -gnatwl -gnatf -gnatE -gnat05 -p -PLibBuildGNADE.gpr
gcc -c -fPIC -g -O0 -fstack-check -pipe -gnatE -gnatU -gnatwl -gnatf -gnatE -gnat05 -I- -gnatA /home/user1/GNADE/src/gnu-db-sqlcli-generic_attr-boolean_attribute.adb
cannot generate code for file gnu-db-sqlcli-generic_attr-boolean_attribute.adb (missing subunits)
这里是规范源（gnu-db-sqlcli-generic_attr-boolean_attribute.ads）
