- Alessandro (12/99) May 08 2015 Hi Rikki,
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 :( !

So it seems my DUB setup was a bit redundant. If I well understood, there is no point in having the root hello_world DUB package setup in the first place. I could just stay with the client and server sub-projects living in their own sub-directories and orchestrate the whole build in one go by means of a custom Makefile from the root directory. This would also allow me to launch the client/server application for testing in a custom-defined way (e.g. launching several clients and a single server in parallel).Hi everyone, I've been learning D for a few months now and really liked it :) !
