Below are the flags set by zmqpp depending on the specified CONFIG variable:
CONFIG_FLAGS =
ifeq ($(CONFIG),debug)
CONFIG_FLAGS = -g -fno-inline -ftemplate-depth-1000
endif
ifeq ($(CONFIG),valgrind)
CONFIG_FLAGS = -g -O1 -DNO_DEBUG_LOG -DNO_TRACE_LOG
endif
ifeq ($(CONFIG),max)
CONFIG_FLAGS = -O3 -funroll-loops -ffast-math -finline-functions \
-fomit-frame-pointer -DNDEBUG
endif
ifneq (,$(findstring $(CONFIG),release loadtest))
CONFIG_FLAGS = -O3 -funroll-loops -ffast-math -finline-functions \
-fomit-frame-pointer -DNO_DEBUG_LOG -DNO_TRACE_LOG -DNDEBUG
endif
For the flags added with CONFIG=debug, '-g' is to be steered by the core
infrastructure (could be '-g1', '-g2' etc.)
The flag '-ftemplate-depth' is only a protection against incorrect code and
not really needed in Buildroot context.
Finally, the flag '-fno-inline' may be useful when really stepping through
zmqpp code, but is a very specific use case.
With the above in mind, not passing CONFIG=debug may actually be better.
Use 'CONFIG=buildroot' instead.
Note that we don't pass an empty 'CONFIG' to avoid confusion, as this
variable is also passed through to the variable BUILD_ENV, even though it is
currently unused.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
