ubuntu 20.04 compiler problem?

[R C]

Hello,


I am trying to compile something, on Ubuntu 20.04, and see this error:


arm-linux-gnueabihf-g++ `pkg-config --cflags libcurl` -std=c++11 
-DUSE_GPIO_TS -DNDEBUG -DRPI -DINCLUDE_HTTPD -O2 -Wall -c 
-fmessage-length=0 -pthread -MMD -MP -MF"f007th_send.d" 
-MT"f007th_send.o" -o "f007th_send.o" "../f007th_send.cpp"
In file included from /usr/include/aarch64-linux-gnu/bits/sigcontext.h:30,
                  from /usr/arm-linux-gnueabihf/include/signal.h:291,
                  from ../RFReceiver.hpp:16,
                  from ../f007th_send.cpp:10:
/usr/include/aarch64-linux-gnu/asm/sigcontext.h:77:2: error: 
‘__uint128_t’ does not name a type; did you mean ‘__uint32_t’?


any ideas?


thanks,


Ron
