makefile - Better rules for gnu make with docker -


suppose source files located in

~/dev/root

inside ~/dev/root number of projects.

e.g.

~/dev/root/libraries/libx ~/dev/root/apps/app/appy ~/dev/root/docker/appy

the build tool use called tundra2 , invoked root level.

so if run tundra2 production appy it'll produce it's output to

~/dev/root/t2-output/linux64-gcc-production-default

the binary directly below directory. there intermediate files located within sub-directories in directory.

now annoying bit. whatever reason, docker build uses daemon process copies directory it's being run temporary directory. produces it's image there. haven't yet spent time try , extend tundra2 cope docker i've been using makefile.

so inside docker/appy directory have dockerfile. alongside have makefile. idea cd directory , run make. if builds, should copy outputs t2-output docker/appy directory , run docker build.

so far, i've specified build targets like:

t2out=../../t2-output/linux64-gcc-production-default tag = "appy" all: $(t2out)/appy  $(t2out)/appy:       cd $(t2out) && tundra2 production appy      cp $< .      docker build -t $(tag) .

etc

the above cumbersome. tried experimenting below vpath doesn't work. make --debug=v confirms it. can suggest alternative? (i might consider build tool provided isn't npm based)

vpath=../../t2-output/linux64-gcc-production-default %.so: ...

sometimes run tundra2 build directly ~/dev/root

so i'm trying make detect appy , copied appy different.

i.e. if ~/dev/root/t2-output/linux64-gcc-production-default/appy different to: ~/dev/root/cluster/docker/appy/appy

then copy ~/dev/root/t2-output/linux64-gcc-production-default/appy ~/dev/root/cluster/docker/appy/appy

and if ~/dev/root/t2-output/linux64-gcc-production-default/appy doesn't exist, if ~/dev/root/cluster/docker/appy/appy exist, should go ../../.. run tundra2 , copy output above docker/appy directory can run docker build

after lot of experimentation found works well. it's quite generic. need make sure, buildroot right location of makefile , services correct. can set buildroot in environment.

buildroot=../../.. t2out=$(buildroot)/t2-output/linux64-gcc-production-default tundra2=cd $(buildroot); tundra2 production docker_tag=remoteregistry.example.com/path/appy  services=appy  all: $(services)     docker build -t $(docker_tag) .  # libraries build target different had specify  # build dependancy $(t2out)/lib.so:     $(tundra2) target  $(t2out)/%:      $(tundra2) $*  %: $(t2out)/%     cp $< $@  clean: $(services)     rm -f $(services)  .phony: clean

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
