Re: Setting up an Ada hello world project

["markww" <markww@gmail.com>]

Ah thanks guys some progress at last. I definitely agree about just
compiling via the command line, my apps will definitely be simple
enough for that. I gave it a shot and this was the output:

C:\Documents and Settings\Mark>gnatmake "C:\helloworld_ada.adb"
gcc -c -IC:\ -I- C:\helloworld_ada.adb
helloworld_ada.adb:4:11: warning: file name does not match unit name,
should be
"hello.adb"
gnatbind -x helloworld_ada.ali
gnatlink helloworld_ada.ali

No .exe is generated under C:\, is that because I received a warning?
Do warnings stop compilation, smae as errors?

Thanks so much,
Mark
