I think I figure out part of what the problem was. As I had used: https://www.gnu.org/software/hurd/microkernel/mach/gnumach/building.html which use: $ CPP='gcc -m32 -E -x c -undef -ansi' CC='gcc -m32' LD='ld -melf_i386' ../configure --prefix= --host=i686-unknown-linux-gnu then: $ make DESTDIR=~/gnu install-data I believe there it installed 64 bit headers in ~/gnu... frankly did not look to them to know.
But: http://darnassus.sceen.net/~hurd-web/microkernel/mach/gnumach/building/ which use: $ TARGET_CPPFLAGS=-I"$GNU"/include ../configure --prefix="$GNU" --host=i686-unknown-linux-gnu then I believee: $ make DESTDIR=~/gnu install-data will install the 32 bit headers files. I am a bit ignoring your "new" README file in git for now... to test if that will fix the problem. But I have new one: paul@jacko:~/mymach/gnumach/build$ LANG=C make gnumach.gz rm -f vm/memory_object_user.user.defs.c cp -p ../vm/memory_object_user.cli vm/memory_object_user.user.defs.c rm -f vm/memory_object_default.user.defs.c cp -p ../vm/memory_object_default.cli vm/memory_object_default.user.defs.c rm -f device/device_reply.user.defs.c cp -p ../device/device_reply.cli device/device_reply.user.defs.c rm -f device/memory_object_reply.user.defs.c cp -p ../device/memory_object_reply.cli device/memory_object_reply.user.defs.c rm -f kern/task_notify.user.defs.c cp -p ../kern/task_notify.cli kern/task_notify.user.defs.c rm -f device/device.server.defs.c cp -p ../device/device.srv device/device.server.defs.c rm -f device/device_pager.server.defs.c cp -p ../device/device_pager.srv device/device_pager.server.defs.c rm -f ipc/mach_port.server.defs.c cp -p ../ipc/mach_port.srv ipc/mach_port.server.defs.c rm -f kern/mach.server.defs.c cp -p ../kern/mach.srv kern/mach.server.defs.c rm -f kern/mach4.server.defs.c cp -p ../kern/mach4.srv kern/mach4.server.defs.c rm -f kern/gnumach.server.defs.c cp -p ../kern/gnumach.srv kern/gnumach.server.defs.c rm -f kern/experimental.server.defs.c cp -p ../kern/experimental.srv kern/experimental.server.defs.c rm -f kern/mach_debug.server.defs.c cp -p ../kern/mach_debug.srv kern/mach_debug.server.defs.c rm -f kern/mach_host.server.defs.c cp -p ../kern/mach_host.srv kern/mach_host.server.defs.c rm -f ipc/notify.none.defs.c cp -p ../ipc/notify.defs ipc/notify.none.defs.c rm -f kern/exc.none.defs.c cp -p ../kern/exc.defs kern/exc.none.defs.c rm -f i386/i386/mach_i386.server.defs.c cp -p ../i386/i386/mach_i386.srv i386/i386/mach_i386.server.defs.c cd . && /bin/bash ./config.status version.c config.status: creating version.c i686-linux-gnu-gcc-10 -DHAVE_CONFIG_H -I. -I.. -ffreestanding -nostdinc -imacros config.h -Ii386 -I. -I../i386 -I../i386/include/mach/sa -I../include -E -fno-builtin-log -Wall -fgnu89-inline -fno-strict-aliasing -fno-stack-protector -no-pie -fno-pic -mno-3dnow -mno-mmx -mno-sse -mno-sse2 -g -O2 -MT vm/lib_dep_tr_for_defs_a-memory_object_user.user.defs.o -MD -MP -MF vm/.deps/lib_dep_tr_for_defs_a-memory_object_user.user.defs.Tpo -c -o vm/lib_dep_tr_for_defs_a-memory_object_user.user.defs.o `test -f 'vm/memory_object_user.user.defs.c' || echo '../'`vm/memory_object_user.user.defs.c mv -f vm/.deps/lib_dep_tr_for_defs_a-memory_object_user.user.defs.Tpo vm/.deps/lib_dep_tr_for_defs_a-memory_object_user.user.defs.Po no -n -cc cat - /dev/null \ -user vm/memory_object_user.user.c -header vm/memory_object_user.user.h \ -list vm/memory_object_user.user.msgids \ < vm/lib_dep_tr_for_defs_a-memory_object_user.user.defs.o /bin/bash: no: command not found make: *** [Makefile:9382: vm/memory_object_user.user.h] Error 127 paul@jacko:~/mymach/gnumach/build$ paul@jacko:~/mymach/gnumach/build$ whereis bash bash: /usr/bin/bash /etc/bash.bashrc /usr/share/man/man1/bash.1.gz paul@jacko:~/mymach/gnumach/build$ I may create a symlink /bin/bash on /usr/bin/bash I find it weird it does that.
