autotools - Build tests depending on program sources -


i want build tests foo program. root makefile.am looks like:

subdirs = src tests

makefile.am src contains:

bin_programs = foo foo_cxxflags = # lot of $(xxx_cflags) foo_ldadd = # lot of $(xxx_libs) foo_sources = # lot of source files

makefile.am tests contains:

check_programs = footesta footestb tests = footesta footestb footesta_sources = footesta.cpp footestb_sources = footestb.cpp

these tests depend on foo symbols , consider create convenience library using foo_libadd = libfoo.la on top , place noinst_ltlibraries = libfoo.la in makefile.am's src. on right way solve this?

you on right way, suggest couple of different options too.

first of all, i'd suggest using non-recursive automake instead of 3 makefile.am have 1 keep date, , reduces nasty factor of autotools.

in particular, using convenience library method across separate makefile.am makes dependency tracking terribly complicated, means may or may not re-run tests if you're changing, say, header file. dependency tracking done when using single, non-recursive, makefile.am.

the other option, again using non-recursive build system, declare variables group of sources, have

self_contained_srcs = foo.h foo1.c foo2.c foo3.c foo_sources = $(self_contained_srcs) main.c other.c  footest_sources = footesta.c $(self_contained_srcs)

this avoids intra-step of running archiver generate .a file , linker unpack it, while still sharing compiled sources (as long don't use per-target cflags).

if plan on using per-target cflags (say want have test-specific code in foo3.c), not able share compiled object files between 2 targets, possible when using variable-expansion, , not possible convenience library, why that's preferred option.

android - Automated my builds -

i have multiple app , android project want automated in build , release sequence. have ant script build , create apk of app. want have 1 script or ant file start build sequence app. maybe don't konw search, can't find easy documentation on ant. the point of use jenkins ant (or maven, i'm not sure of difference between them now) automated build sequence when people commit on project. any int appreciated maven dependencies (over ant) don't need pass around jars. recommend maven on ant day. syntax , overall process easier understand, @ end of both build tools. if able to, more recommend upgrading gradle. easy create different build types , create them ./gradlew assemble here project jake wharton can see power of gradle. there release , debug build, can make lot more if like. https://github.com/jakewharton/u2020 here android docs gradle http://tools.android.com/tech-docs/new-build-system/user-guide . if can't find looking here, check out main grad...

how to proxy from https to http with lighttpd -

i have internal site (192.168.2.1) accessible http on different server run public web-server using lighttpd. can make internal site accessible outside work follows $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "192.168.2.1", "port" => 8000 ) ) } this works, use https outside world. question is, how can proxy going https http ? i've tried this: $server["socket"] == ":443" { $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "http://192.168.2.1", "port" => 8000 ) ) } } but doesn't seem wor...
