Further oddness, trying with thermistor.comp in user_comps, first with plain gcc and minimal options: gcc -I/home/andypugh/linuxcnc-dev/include/ -DULAPI -H thermistor.c Seems OK (up to the point that it can't find HAL). It finds stddef / stddarg / spawn with no difficulty. However, same system, same file andypugh@rm-one:~/linuxcnc-dev/src/hal/user_comps$ halcompile --compile thermistor.comp gcc -Os -g -I. -I/usr/realtime-4.14.174-rtai-amd64/include -I. -I/usr/realtime-4.14.174-rtai-amd64/include -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -O2 -march=x86-64 -fomit-frame-pointer -pipe -D__IN_RTAI__ -mcmodel=kernel -nostdinc -ffreestanding -fno-pic -fno-builtin -fno-common -fno-unwind-tables -fno-asynchronous-unwind-tables -fexcess-precision=standard -frounding-math -fsignaling-nans -mieee-fp -mhard-float -mpreferred-stack-boundary=4 -mstackrealign -mfpmath=sse -msse -msse2 -DRTAI=5 -fno-fast-math -mieee-fp -fno-unsafe-math-optimizations -DRTAPI -D_GNU_SOURCE -Drealtime -D__MODULE__ -I/home/andypugh/linuxcnc-dev/include -Wframe-larger-than=2560 -URTAPI -U__MODULE__ -DULAPI -H -Os -o thermistor /tmp/tmpM2Lxkj/thermistor.c -Wl,-rpath,/home/andypugh/linuxcnc-dev/lib -L/home/andypugh/linuxcnc-dev/lib -llinuxcnchal -lm . /home/andypugh/linuxcnc-dev/include/rtapi.h In file included from /tmp/tmpM2Lxkj/thermistor.c:2: /home/andypugh/linuxcnc-dev/include/rtapi.h:69:10: fatal error: stddef.h: No such file or directory Do any of those compiler flags overwrite or remove the standard gcc paths? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
