问题
I am trying to install rtems 5 on my ubuntu-19.04 machine, using the instructions in QuickStart, everything is ok until section 2.7, when it appears that the gdb that was built is missing the "sim" target.
The complete sequence of commands is :
2022 mkdir -p $HOME/quick-start/src
2023 cd $HOME/quick-start/src
2024 git clone git://git.rtems.org/rtems-source-builder.git rsb
2025 git clone git://git.rtems.org/rtems.git
2026 cd $HOME/quick-start/src/rsb/rtems
2027 ../source-builder/sb-set-builder --source-only-download 5/rtems-sparc
2028 cd $HOME/quick-start/src/rsb/rtems
2029 ../source-builder/sb-set-builder --prefix=$HOME/quick-start/rtems/5 5/rtems-sparc
2030 $HOME/quick-start/rtems/5/bin/sparc-rtems5-gcc --version --verbose
2031 cd $HOME/quick-start/src/rtems
2032 export PATH=$HOME/quick-start/rtems/5/bin:"$PATH"
2033 ./bootstrap -c
2034 $HOME/quick-start/src/rsb/source-builder/sb-bootstrap
2035 mkdir -p $HOME/quick-start/build/b-erc32
2036 cd $HOME/quick-start/build/b-erc32
2037 export PATH=$HOME/quick-start/rtems/5/bin:"$PATH"
2038 $HOME/quick-start/src/rtems/configure --prefix=$HOME/quick-start/rtems/5 --enable-maintainer-mode --target=sparc-rtems5 --enable-rtemsbsp=erc32 --enable-tests
2039 cd $HOME/quick-start/build/b-erc32
2040 make
2041 cd $HOME/quick-start/build/b-erc32
2042 make install
2043 cd $HOME/quick-start/build/b-erc32
2044 rtems-test --rtems-bsp=erc32 --rtems-tools=$HOME/quick-start/rtems/5 .
A check of the source builder says OK:
user@machine:~/quick-start/build/b-erc32$ $HOME/quick-start/src/rsb/source-builder/sb-check
RTEMS Source Builder - Check, 5 (4a6f476c14aa)
Environment is ok
The Actual test & output:
user@machine:~/quick-start/build/b-erc32$ rtems-test --rtems-bsp=erc32 --rtems-tools=$HOME/quick-start/rtems/5 .

Does anyone more experienced with rtems know how to build the sparc-rtems5-gdb properly so this can be corrected ?
回答1:
The SIS (Software Instruction Simulator) has been removed from GDB and is now available as a separate command called sis. Please check if this command has been built and installed with your RTEMS tool set. If present please use --rtems-bsp=erc32-sis as the test command BSP:
rtems-test --rtems-bsp=erc32-sis --rtems-tools=$HOME/quick-start/rtems/5 .
The SIS simulator in GDB was being maintained as a patch to GDB in the RTEMS tools and this created work everytime we updated the GDB version. A separate program is simpler to maintain and can be used with GDB via the remote protocol so everything we had with the patch is still present but we do not need to keep a patch hang around. The new sis command also supports RISCV simulation as well.
