I'm installing RTEMS in Ubuntu 19.10. In the last step of https://docs.rtems.org/releases/rtems-docs-4.11.3/user/installation/index.html#rtems-tools-and-kernel (../source-builder/sb-set-builder --prefix=/opt/rtems/4.11 4.11/rtems-i386) it shows next error message (I've deleted the first part of the report because it 's impossible to post more than 30000 characteres):

[..]

For more information see: How to configure RTEMS in Eclipse? Thanks, Ana

  • It seems you are missing the zlib development package? Have you installed ```sudo apt-get install zlib1g-dev```? After that execute ```./configure``` and try to build it again. You should get further. – Gerhard Stein Apr 27 '20 at 06:40
  • After install zlib1g-dev, I've tried 'sudo ../source-builder/sb-set-builder --prefix=/opt/rtems/4.11 4.11/rtems-i386' but it returns: Build FAILED. log-> [..] make[2]: *** [Makefile:1058: cp/except.o] Error 1 make[1]: *** [Makefile:3975: all-gcc] Error 2 make: *** [Makefile:863: all] Error 2 shell cmd failed: /bin/sh -ex /home/user/development/rtems/releases/rtems-source-builder-4.11.0/rtems/build/i386-rtems4.11-gcc-4.9.3-newlib-2.2.0.20150423-x86_64-linux-gnu-1/doit error: building i386-rtems4.11-gcc-4.9.3-newlib-2.2.0.20150423-x86_64-linux-gnu-1 – athernandez Apr 27 '20 at 11:32
  • Have you tried to enable the logging for the source builder? Add a "--log=mylogfile.log" to your sb-set-builder command line. Sometimes it helps to have the complete log for analyzing the problem. – Christian Mauderer Apr 27 '20 at 18:06
  • By the way: You are using a 4.11 version of RTEMS. Note that the 4.11 release is now quite some time back. RTEMS currently has only very few releases with long times between them. But the development version is quite stable nearly all of the time. Beneath that the 5.1 release will be out in the next weeks (not sure exactly when) and you might can think about using one of the snapshot release packages. – Christian Mauderer Apr 27 '20 at 18:09
