Hi everyone,
I've been learning D for a few months now and really liked it :) !
Currently I'm experimenting with client/server application
development using the ZeroMQ library D wrapper called "zmqd".
Although I could successfully build the basic hello_world
application with a custom written Makefile using dmd/rdmd, I've
tried to use the DUB package manager to achieve the same goal,
but I'm having some issues with it.
By following the DUB documentation at
http://code.dlang.org/package-format#build-options I created a
main dub project called "hello_world" (dub init hello_world) and
set up two sub-packages therein called "client" and "server" (dub
init client|server).
Then I configured the three dub.json files as follows:
hello_world/dub.json:
{
"name": "hello_world",
"description": "Hello World client/server application using ZMQ",
"targetType": "none",
"dependencies": {
"hello_world:client": "*",
"hello_world:server": "*"
},
"subPackages": [
"./client/",
"./server/"
]
}
hello_world/client/dub.json:
{
"name": "client",
"description": "Hello World client application using ZMQ",
"targetType": "executable",
"sourceFiles": ["source/hwclient.d"],
"dependencies": {
"zmqd": "~>1.0.0-alpha"
}
}
hello_world/server/dub.json -> same as above with "server"
substituting "client"
With this setting, from within "hello_world" directory, I can
build client and server individually with:
$ dub build hello_world:client
$ dub build hello_world:server
but when I simply try:
$ dub build
to build the whole thing at once, I get an error saying:
Error executing command build:
Main package must have a binary target type, not none. Cannot
build.
But if I change the "targetType" to "executable" or "autodetect"
in hello_world/dub.json I get the error:
Configuration 'application' of package hello_world contains no
source files. Please add {"targetType": "none"} to it's package
description to avoid building it.
Error executing command build:
Main package must have a binary target type, not none. Cannot
build.
What shall I do to have all sub-packages automatically built when
I build the main package? Is there a way to specify a small bash
script to have custom commands executed when giving the "dub run"
command?
Sorry for the long post :( !
$ dub build hello_world:client ; dub build hello_world:server
Dub wasn't meant to build, more or less completely unrelated project
targets at the same time.
