Hi,
I try to use real-time UDP communicaition block in Simulink Desktop Real-time. My program runs well in Normal mode. But when I try to run it in External mode, it reports that
C:/MATALB~1/toolbox/sldrt/clang/win64/clang -emit-llvm -c -m64 -O4 -DINT64_T="long long" -DUINT64_T="unsigned long long" -fno-ms-compatibility -U_MSC_VER -U__STDC_HOSTED__ -Wno-switch-enum -Wno-empty-body -IC:/MATALB~1/toolbox/sldrt/lib/include -I. -I.. -IC:/MATALB~1/simulink/include -IC:/MATALB~1/extern/include -IC:/MATALB~1/rtw/c/src -IC:/MATALB~1/rtw/c/src/ext_mode/common -IC:/MATALB~1/toolbox/shared/can/src/scanutil -IC:/MATALB~1/toolbox/sldrt/src -IC:/Users/qzlab -IC:/Users/qzlab/Deskrealtime_sldrt_win64 -IC:/MATALB~1/extern/include -IC:/MATALB~1/simulink/include -IC:/MATALB~1/rtw/c/src -IC:/MATALB~1/rtw/c/src/ext_mode/common -IC:/MATALB~1/toolbox/coder/rtiostream/src -DTGTCONN -DEXT_MODE -DON_TARGET_WAIT_FOR_START=1 -DEXT_MODE -DUSE_RTMODEL -DMODEL=Deskrealtime -DRT -DNUMST=1 -DTID01EQ=0 -DNCSTATES=0 -DMT=0 -o "slrtIPConfig.obj" "C:/MATALB~1/toolbox/slrt/blocks/UDP/slrtIPConfig.c" C:/MATALB~1/toolbox/slrt/blocks/UDP/slrtIPConfig.c:13:10: fatal error: 'socketfuncs.h' file not found #include "socketfuncs.h" ^ 1 error generated. gmake: *** [slrtIPConfig.obj] Error 1
Can anyone give me some suggestions?
Thanks,

Thank you for suggestions, but it doesn't solve the problem.
I use Simulink Destop Real-time. So, in code generation, I choose sldrt.tlc (SIMULINK DESKTOP REAL-TIME).
When I try to use UDP block in Embedded Coder Toolbo or DSP Toolbox, the errors are the same:

It seems that in SIMULINK DESKTOP REAL-TIME external mode, some libs are lost.
Thanks,
