Hello Heinz and everyone, Thank you so much, with this email, I will try to clear all the things, and what is the status for now.
First. let me tell you the current status: Vijay helped me last night in an offlist discussion to clear the confusions which I was having (I will mention them below) due to which I was able to build and install RTEMS 4.10 for pc386 successfully. With that, all my previous errors were resolved. Below is the detail of all the steps, I followed. Let me tell that my development environment was earlier set up for RTEMS5. For building EPICS with RTEMS, I thought it will be right to first build RTEMS 4.10 for pc386. In order to do that, I made the directory i) $HOME/development/rtems_dev ii) I extracted rtems-4.10.2 from here https://ftp.rtems.org/pub/rtems/releases/4.10/4.10.2/ iii)I created another directory rtems_dev/src iv)Inside src, I cloned rsb and moved to 4.10 branch. v) After performing checks, I entered to rsb/rtems and used this command: '../source-builder/sb-set-builder --prefix=/home/mritunjay/development/rtems_dev/rtems-4.10.2 4.10/rtems-i386' Even though the build completed successfully, this was the point where I made the error. I used the RTEMS source as the prefix which was causing all the problems. vi) After the discussion with Vijay and getting cleared, I deleted everything except the RTEMS RSB and restarted the process with prefix and source different this time and rebuilt the compiler tools using RSB. vii) Now the directory structure under $HOME/development/rtems_dev/ looked like: | rtems-4.10.2 | 4.10 | src/rsb | kernel/pc386 I also used this command: "export PATH=$HOME/development/rtems_dev/4.10/bin:$PATH" vi) Then I went to rtems_dev/rtems-4.10.2 and used this command: "./bootstrap -c && $HOME/development/rtems_dev/src/rsb/source-builder/sb-bootstrap" vi) After this I went insid directory $HOME/development/rtems_dev/kernel/pc-386 vii) Inside pc-386, I used the following command: ''$HOME/development/rtems_dev/rtems-4.10.2/configure --target=i386-rtems4.10 --disable-posix --enable-rtemsbsp=pc386 --enable-tests=samples --prefix=/home/development/rtems_dev/rtems-4.10.2 --enable-cxx" viii) Then I entered the make command which ran successfully and the make install was also successful. So all the errors were resolved and I moved on to build EPICS now for RTEMS 4.10. I also used this command: '''export RTEMS_MAKEFILE_PATH=$HOME/development/rtems_dev/4.10/i386-rtems4.10/pc386'' Location of epics-base in my system is as follows: "$HOME/development/EPICS/epics-base" After this, I followed the tutorial you sent to build EPICS for rterms-4.10 for pc-386 which is: > Very roughly: > git clone —recursive epics-base > > in epics-base/configure/CONFIG_SITE > set > CROSS_COMPILER_TARGET_ARCHS= > What I entered: CROSS_COMPILER_TARGET_ARCHS= RTEMS-pc386 > e.g. RTEMS-pc386 > or RTEMS-xilinx_zynq_a9_qemu > > in epics-base/configure/os there must be a file for the target used, > e.g. > CONFIG.Common.RTEMS-xilinx_zynq_a9_qemu > or > CONFIG.Common.RTEMS-pc386 > Checked. CONFIG.Common.RTEMS-pc386 was there > > Then you have to set in configure/os/CONFIG_SITE.Common.RTEMS > where to find RTEMS: > > # Where to find RTEMS > # > # APS: > #RTEMS_VERSION = 4.10.2 > #RTEMS_BASE = /usr/local/vw/rtems/rtems-$(RTEMS_VERSION) In my system, I entered this: #APS RTEMS_VERSION = 4.10 RTEMS_BASE = /home/mritunjay/development/rtems_dev/$(RTEMS_VERSION) I followed the above instructions and used the 'make' command. While the earlier errors are resolved, The latest error that I have encountered is this after using make command.: ".......Info': /home/mritunjay/development/EPICS/epics-base/modules/libcom/src/O.RTEMS-pc386/../osi/os/RTEMS/osdThread.c:747: undefined reference to `pthread_getschedparam' collect2: ld returned 1 exit status ../../../../configure/RULES_BUILD:212: recipe for target 'libComTestHarness' failed make[4]: *** [libComTestHarness] Error 1 make[4]: Leaving directory '/home/mritunjay/development/EPICS/epics-base/modules/libcom/test/O.RTEMS-pc386' ../../../configure/RULES_ARCHS:58: recipe for target 'install.RTEMS-pc386' failed make[3]: *** [install.RTEMS-pc386] Error 2 make[3]: Leaving directory '/home/mritunjay/development/EPICS/epics-base/modules/libcom/test' ../../configure/RULES_DIRS:85: recipe for target 'test.install' failed make[2]: *** [test.install] Error 2 make[2]: Leaving directory '/home/mritunjay/development/EPICS/epics-base/modules/libcom' ../configure/RULES_DIRS:85: recipe for target 'libcom.install' failed make[1]: *** [libcom.install] Error 2 make[1]: Leaving directory '/home/mritunjay/development/EPICS/epics-base/modules' configure/RULES_DIRS:85: recipe for target 'modules.install' failed make: *** [modules.install] Error 2" I hope this time I was explicit in writing what I did and what error I am facing as of now. It would be kind of you to guide where I am going wrong.
