check if the makefile uses those exports.

The Makefile is pretty straight forward (https://github.com/gpgpu-sim/ispass2009-benchmarks/tree/master/AES) How can I check that? Sent from Mail for Windows 10

The error is in an undefined reference to a symbol in boost.system. Because of the way GCC links, the order matters as anything not referenced up to that point is removed. Try changing this line: LINKFLAGS := -L$(BOOST_LIB) -lboost_system -lboost_filesystem$(BOOST_VER) To LINKFLAGS := -L$(BOOST_LIB) -lboost_filesystem$(BOOST_VER) -lboost_system IE: Switch the order of system and filesystem. Hope this helps, -- chris

Whilst this isn't really anything to do with boost per se I feel your pain having inherited various "clever" makefile solutions in my career. That looks like the compile line (ie building the .o files) rather than the link line - however having $(VERBOSE) in front looks promising I imagine that is set to @ which is an "echo off" style feature in make - ie only outputs the output of the command to stdout and not the actual invocation. If you switch that off you can probably get make to output the actual commands it is using - then you can see what exactly is happening rather than having to guess. How $(VERBOSE) gets set will be specific to that particular makefile / nest of makefiles - possibly there is some command line parameter checked when you call them which sets this for you (DEBUG=ON used to be a common convention). If you can't determine that then try forcing VERBOSE to be blank or if all else fails edit the makefile to remove $(VERBOSE) from the calling of the linker (which is probably done using $(CXX) without the -o flag) One other thing that can help with debugging makefiles is add a debug target .PHONY: debug # to debug variables # copy this to a makefile and use via command line # make V="CFLAGS ANOVAR" debug debug: $(foreach v,$(V), \ $(warning $v = $($v))) Which is just adding a target "debug" to make which outputs the make variables you pass in by V make V="VERBOSE BOOST_LIB" debug So you are telling make to build target "debug" and that will simply output the name and value of the variables you have passed. There are limitations to this technique since some variables in make can alter their values depending on stage of processing (basically the difference between A := VALUE and A = VALUE in a makefile) but sometimes it saves a lot of time and head scratching.

is it possible the gcc linker is not finding the proper lib file ? all look good, I assume that the linker is add lib in front of the name of your argument, does it add suffix also ? look for an option to get the list of libs it found when trying to link. 2 thinks can happen: the lib name is not the one you think (in windows they have .lib extension, not .so) it finds another lib with the same name in another directory. you have the link cmd, use it directly it will be easier maybe to find your problem make sure you understand all the options use for linking, your problem could be there also. 2017-10-17 12:50 GMT-04:00 mahmood n via Boost-users :
