Script update for Ubuntu 19.04

ggmero67 commented 5 years ago

Hello, Thank for your great work! I tried for some times now to make avr-ada work on Ubuntu 19.04 and I get some "technical" issues that I managed to resolve step by step:

path basename in the script refers to your personal $HOME
install path should be writtable by the user, because "sudo ./build-avr-ada.sh" doesn't work
gcc and gnat have to be aligned (same version)
mpfr, mpc gmp can be installed from ubuntu repos
avr-libc needs to be bootstraped before configure, and this requires automake/autoconf to be installed on the machine ...

I believe some update in the build script and/or the readme could help others... Is the project still open to modifications?

Hi ggmero67

I'm trying to compile one myself, and has got part way. Hopefully you can help me complete this task!? The script bumps out compiling GCC/GNAT with:

checking for suffix of object files... configure: error: in `.../build/gcc-obj/avr/avrtiny/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

build/gcc-obj/avr/avrtiny/libgcc/config.log:

Fatal error: unknown MCU: avrtiny
...
configure:3701: error: in `/home/pdj/Projects/build-avr-ada-toolchain/build/gcc-obj/avr/avrtiny/libgcc':
configure:3704: error: cannot compute suffix of object files: cannot compile

I hope you can help me I can make a fork and pull-request for this project, so others can benefit from it.

I've replaced the path:

-AVRADA_PATCHES=/home/re/Devel/AVR-Ada.git/avr-ada/patches
+AVRADA_PATCHES=$BASE_DIR/patches

I also added: ./bootstrap just before configure AVR-LIBC

Using Debian testing/Bullseye

gnat 8.3.0
gcc (Debian 8.3.0-6) 8.3.0
libmpfr-dev 4.0.2-1
libmpc-dev 1.1.0-1
libgmp-dev 2:6.1.2+dfsg-4

@ggmero67, I've forked the project at https://github.com/Knaldgas/build-avr-ada-toolchain and invited you as collaborator (so you can push updates yourself). I've created a branch for the work "Fix-build-script-for-gcc/gnat-8.3-on-Debian-testing/bullseye" - Please use that if you are pushing changes :-) When it works I will create a pull-request for Rolf.

Found that calling the make installs will work if prepended with sudo --preserve-env=PATH

Hi there, i'm also trying to build the compiler on Mint 19.3 (based on Ubuntu 18.04) and have the same problems. @Knaldgas I can't see you dev branch. Is there some update about this bug?

I think you should fetch from https://github.com/RREE/build-avr-ada-toolchain

It's some time ago since I last compiled, but I am going to resume work on AVR's within the next few weeks, so I'm going to retry the script soon. Which problem do you have?

Here are my steps:

My system compiler is gcc 7 (from build-essential)
I fetched master from https://github.com/RREE/build-avr-ada-toolchain
I updated build-avr-ada.sh:
- use make -j2 to speed up the build
- set 'yes' for build_avrada, build_binutils

Build fails when building GNAT:

fmap.adb:304:18: "Null_FD" is undefined
gnatmake: "/home/aurelien/avr_ada/build-avr-ada-toolchain/build/gcc-9.2.0/gcc/ada/fmap.adb" compilation error
 ../gcc-interface/Makefile:468: recipe for target 'gnatmake-re' failed

Could it be a consequence of too old host gcc (7.4) ?

arcadien commented 4 years ago

If i downgrade target GCC from 9.2 to 7.4 to cope with my host version, it builds. The compilation fails on AVR-Ada RTS, but no support is provided for GCC 7.4 so that sounds normal.

arcadien commented 4 years ago

btw *.ads files from GCC are not copied in /opt, hence avr-gnatmake cannot produce executables

Finally,I installed gcc-8, exported it as default compiler using export CC: everything went fine

gcc-9 did not work?

arcadien commented 4 years ago

It was not clear for me that host compiler must match the one builded by the script. Anyway, it is out of the scope of this issue. I will post in a new one of needed. Thanks for your support
