NSIS: Install a folder based on 32/64 bits -


i'm working on installer script needs install 1 of 2 folders based on os bits. selection occurs fine far reason see 1 folder within resulting installer.

the relevant sections below:

;windows 32 or 64 bit version !include "x64.nsh" section "jre 64 bit" section5         sectionin ro          ;use right java version         detailprint "jre extraction..."         setoutpath "$instdir\${appdir}\jre"         file /a /r "${srcdir}\..\..\jre\jre_64\jre\*.*"         detailprint "jre extraction complete!" sectionend  section "jre 32 bit" section6         sectionin ro          ;use right java version         detailprint "jre extraction..."         setoutpath "$instdir\${appdir}\jre"         file /a /r "${srcdir}\..\..\jre\jre_32\jre\*.*"         detailprint "jre extraction complete!" sectionend  function .oninit   #determine bitness of os , enable correct section   intop $0 ${sf_selected} | ${sf_ro}   ${if} ${runningx64}     sectionsetflags ${section5} $0     sectionsetflags ${section6} ${section_off}   ${else}     sectionsetflags ${section5} ${section_off}      sectionsetflags ${section6} $0   ${endif} functionend

both folders exists there no warning. instead of seeing 2 folders (jre_64 , jre_32) see 1 jre folder within installer.

installer contents

is expected behavior? i'm using nsis 2.51. resulting instaler can found here.

you can see full script here.

i guess it's because of delta compression, 2 jre directories should have quite similar contents. structure when viewing using 7-zip doesn't represent internal structure of installer, seems quite opaque.

i tried find tool "properly" unpack installer (like innounp inno setup), without success. confirms nsis installer structure should opaque.

did manual testing determine if installer works expected in both cases?

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
