cmake ignores static library link request -


i've searched hours on how solve , tried did not work. i'm trying link statically libraries, (libpoco, libmysqlcpp, libmysqlclient, libssl).

i'm using cmake, , although defining static library, cmake looks dynamic one. know have required libraries in static archive in filesystem, , know are.

set(cmake_library_path ${cmake_library_path}               /lib               /usr/lib               /usr/lib64               /usr/local/lib               /usr/local/lib64               /usr/lib/x86_64-linux-gnu)  find_library(poco_net names libpoconet.a paths cmake_library_path static imported) find_library(poco_util names libpocoutil.a paths cmake_library_path static imported) find_library(poco_xml names libpocoxml.a paths cmake_library_path static imported) find_library (mysql_client names libmysqlclient.a paths cmake_library_path static imported) find_library (mysql_cpp names libmysqlpp.a paths cmake_library_path static imported) find_library (libssl names libssl.a paths cmake_library_path static imported)  if (poco_net , poco_util , poco_xml , mysql_client , mysql_cpp , libssl)   message(status ${poco_net})   message(status ${poco_util})   message(status ${poco_xml})   message(status ${mysql_client})   message(status ${mysql_cpp})   message(status ${libssl})   target_link_libraries(icarus              poconet             pocoutil             pocoxml             mysqlpp             mysqlclient             ssl) else ()   message(fatal_error "fatal error: missing library") endif (poco_net , poco_util , poco_xml , mysql_client , mysql_cpp , libssl)

but when run cmake .. is:

-- /usr/local/lib/libpoconet.so -- /usr/local/lib/libpocoutil.so -- /usr/local/lib/libpocoxml.so -- /usr/lib/x86_64-linux-gnu/libmysqlclient.so -- /usr/lib/libmysqlpp.so -- /usr/lib/libssl.so

and when try compile, undefined references since using -static flag. missing here? there way force cmake lookup static libraries instead of dynamic ones? going wrong way this? thank you.

it looks you're getting wee bit confused between add_library , find_library commands. find_library doesn't take arguments of static or imported.

also, you've not wrapped cmake_library_path in ${} inside find_library call, you're passing 3 paths of "cmake_library_path", "static" , "imported" cmake's search routine, not intended 6 paths of ${cmake_library_path}.

finally, since ${cmake_library_path} first port of call in cmake search routine, there's no need add explicitly find_library commands.

so can like:

set(cmake_library_path ${cmake_library_path}               /lib               /usr/lib               /usr/lib64               /usr/local/lib               /usr/local/lib64               /usr/lib/x86_64-linux-gnu)  find_library(poco_net names libpoconet.a) find_library(poco_util names libpocoutil.a) find_library(poco_xml names libpocoxml.a) find_library(mysql_client names libmysqlclient.a) find_library(mysql_cpp names libmysqlpp.a) find_library(libssl names libssl.a paths)  if(poco_net , poco_util , poco_xml , mysql_client , mysql_cpp , libssl)   message(status ${poco_net})   message(status ${poco_util})   message(status ${poco_xml})   message(status ${mysql_client})   message(status ${mysql_cpp})   message(status ${libssl})   target_link_libraries(icarus              ${poco_net}             ${poco_util}             ${poco_xml}             ${mysql_client}             ${mysql_cpp}             ${libssl}) else()   message(fatal_error "fatal error: missing library") endif()

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
