Hit send before I had chance to finish :) ignore the missing tab but when trying to compile (after sourcing the SDK environment) I get sh4-poky-linux-gcc -ml -m4 --sysroot=/opt/sdk/vms/2.0.2/sysroots/sh4-poky-linux -o HelloWorld HelloWorld.o /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find crt1.o: No such file or directory /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find crti.o: No such file or directory /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find crtbegin.o: No such file or directory /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find -lgcc /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find -lgcc_s /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find -lc /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find -lgcc /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find -lgcc_s /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find crtend.o: No such file or directory /opt/sdk/vms/2.0.2/sysroots/x86_64-pokysdk-linux/usr/libexec/sh4-poky-linux/gcc/sh4-poky-linux/4.9.3/real-ld: cannot find crtn.o: No such file or directory So I tried the compiler and sysroot from the build CC=/ws/vms/vms-rsc-yocto-build/build_vms/tmp/sysroots/x86_64-linux/usr/bin/sh4-poky-linux/sh4-poky-linux-gcc SYSROOT=/ws/vms/vms-rsc-yocto-build/build_vms/tmp/sysroots/sh7760 hellomake: HelloWorld.c $(CC) --sysroot=$(SYSROOT) -o HelloWorld HelloWorld.c and it compiles fine.

Anyone know why this has happened and how I can fix it before I wade into the populate_sdk task. We are using the Jethro branch and we have fixed the GCC version to 4.9.3 because this version works for SH4. Many Thanks, Martin. -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
