c++ - Delay Loading DWMAPI on Windows XP and CodeBlocks -

i have project i'm been fighting build windows (xp) month solid now. project uses gtkmm-3, c++, , latest gcc-tdm compiler. ide codeblocks 13.14.

i'm making progress, however, getting hung on error message...

ld.exe cannot find -ldwmapi

now, dwmapi dll available on windows vista , above. according research, can delay loading of dlls in cases present on some systems, not on others.

the problem is, have no clue how on codeblocks. -z lazy option not accomplish this. if delay loading impossible, how around dwmapi dependency. there has way!

full build command: (errors @ bottom)

lazy linking, -z lazy, gnu linker's default on unix-like systems , not supported in mingw windows ports. (this has nothing code::blocks)

i cannot fathom hope repose in lazy linking overcome problem, doesn't matter. if can't count on shared library available on target systems of project 1 customary course link library statically in executable. can here.

the 32-bit tdm gcc using not ship dwmapi in static library corresponding 64-bit toolchain ship both 64- , 32-bit builds of it, respectively:

<tdm-gcc-64-install-dir>/x86_64-w64-mingw32/lib/libdwmapi.a 

and

<tdm-gcc-64-install-dir>/x86_64-w64-mingw32/lib32/libdwmapi.a 

those paths among linker defaults toolchain, link library if mention -ldwmapi in linker options (as have done).

the absence of libdwmapi.a in 32-bit toolchain may anomaly, or may decision based on fact library not around until windows had transitioned 64-bit in mainstream.

you have 3 options then:

1. if have no committment building 32-bit can swap corresponding 64-bit toolchain (and 64-bit libraries accross board)

2. swap 64-bit toolchain continue build 32-bit adding option -m32 compiler , linker

3. install 64-bit toolchain, continue using 32-bit toolchain, add -l<tdm-gcc-64-install-dir>/x86_64-w64-mingw32/lib32 linker search paths, after have specified.

a couple of unrelated observations:-

in , your previous question of g++ commandline options appear 3 times each! - yielding 4k commandlines make tiresome parsing. code::blocks ide, way in can have produced triplication setting of these options once in global settings -> compiler, again in overall project settings infiltrator -> build options -> infiltrator, , yet again in project debug/release configuration settings infiltrator -> build options -> infiltrator -> debug/release.

these 3 levels of settings form inheritance hierarchy. not make any project specific settings globally compiler. doing makes them properties of compiler , applied every other project build compiler. project settings invariant between project configurations (debug/release) should made once @ project level. debug , release options should set @ project configuration level.

lastly see have chosen install tdm-gcc-32 variant dwarf2 style exception handling, rather default package (per executable installer) setjump-longjump style exception handling. carries risk. while dw2 exception handling more efficient sjlj, foreign windows , fail if exception must propagate through windows library not built in same way. setjump-longjump mechamism, though slower, relies on primtive, long standardized c library facilities c or c++ compiler implements.
