makefile - GNU Make Simply Expanded Variables and Automatic Variables -


i have simple makefile go project , want able run akin to: make release-all

in order build releases couple of different platforms (e.g. windows, linux, darwin).

my make file looks this:

gooses = darwin windows linux goarchs = amd64 386 .phony: release-all $(gooses) $(goarchs) release: $(gooses)  $(gooses): goos := app $@ $(gooses): $(goarchs)  $(goarchs): goarch := $@ $(goarchs): build  build: goos=$(goos) goarch=$(goarch) go install ...

when try build though, get:

goos= goarch= go install ...

so far can tell := isn't causing $@ evaluated on assignment. possible acheive somehow? if not, want iterate on each item in list of os'es , on each of architectures until i've built options. @ least possible without specifying each architecture/os combo explicitly?

assuming command works, handle iteration:

gooses = darwin windows linux goarchs = amd64 386  build:  define template build: build_$(1)_$(2) .phony: build_$(1)_$(2) build_$(1)_$(2):     goos=$(1) goarch=$(2) go install ... endef  $(foreach goarch,$(goarchs),$(foreach goos,$(gooses),$(eval $(call template,$(goos),$(goarch)))))

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
