build.sh fails

[ShaneKent]

We run the following code:

git clone https://github.com/zylin/zpugcc.git
cd zpugcc/toolchain
sh fixperm.sh
. env.sh
sh build.sh

and we receive this error after a while:

Hello Shane Kent,

I've looked in my toolchain/build/opcodes/po/Makefile and found a difference:

GMSGFMT = PATH=../src:$$PATH /usr/bin/msgfmt

On your machine the gettext-tools are missing so this line is wrong:

GMSGFMT = PATH=../src:$$PATH no

To solve the problem just install the gettext-tools

regards,

Bert

[ShaneKent]

Running the following solved this problem:

sudo apt-get install gettext

The build makes it much farther and then fails with the following information:

...

checking for libintl.h... yes

[ShaneKent]

Running the following solved the issue:

sudo apt install flex

Again, the build lasts for much longer this time before failing here:

[ShaneKent]

That error was solved by performing the recommendation listed here: http://compilationhell.blogspot.com/2011/08/exceptc-undefined-reference-to.html

Remove zpugcc/toolchain/gcc/gcc/cp/cfns.h
Run `sudo apt install gperf`
Run `sh build.sh`

We now fail at this point and we're having a hard time determining the next step:

Hello Shane,

it tried to build the actual toolchain and got the same errors as you.

At the moment I have no glue, what to do.

Bert

[alvieboy]

That's a warning. I suspect the error might be above those lines. Care to post the full compile output ?

[ShaneKent]

@bert-lange @alvieboy

Please see the attached file showing the full compilation output. We're eager to know what to do next.

output.txt

[alvieboy]

That still looks like the issue from missing 'gperf'. If you start the build from scratch now (including "configure" step) does it still fail in the same location?

[ShaneKent]

@alvieboy Would you mind listing out what the "configure" step is? We are trying to run this block to build the repository from scratch and we don't see any information about a configure step:

git clone https://github.com/zylin/zpugcc.git
cd toolchain/toolchain
sh fixperm.sh
. env.sh
sh build.sh
tar -cjvf zpugcclinux_unstable.tar.bz2 install 

[bert-lange]

The configure tool is called twice from build.sh:

../binutils/configure --target=zpu-elf --prefix=pwd/../install

../gcc/configure --target=zpu-elf --prefix=pwd/../install --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib --disable-shared --enable-newlib -v --enable-checking=misc,tree,rtl,rtlflag,gc,gcac,fold --disable-multilib --disable-threads --enable-sjlj-exceptions --enable-libstdcxx-allocator=malloc

We deleted the /zpugcc directory and tried to run through the clone and build steps again and we verified that the build.sh file contains those calls to the configure command. We also verified that gperf is installed by using the following:

main@main:~/zpugcc/toolchain$ sudo apt install gperf
[sudo] password for main: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gperf is already the newest version (3.1-1build1).
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

Unfortunately we got the same error when we reran the commands.

[ShaneKent]

Does anyone have any suggestions on how to continue this? We are currently running this on Ubuntu 20.04.2.0, but we're open to running a different Linux distro if there is a recommended one.

[bert-lange]

Hello Shane!

My suggestion is to go back in time (with older ubuntu in an virtual machine) and find the point where the build fail.

My zpu-toolchain has a time stamp from june 2020, but maybe this is the date where I migrated to the current system, I don't remember exactly.

But there where times, where building the toolchain work without problem. On linux and on cygwin environment.

I would try this by myself, but I have to much work at the moment.

regards,

Bert

Hi Shane!

Best solution is to edit the ./toolchain/build.sh file and add a line in a way that, the build.sh file ends up like the following:

export PATH=`pwd`/install/bin:$PATH export CC="gcc -fgnu89-inline" rm -rf gccbuild

This solution can be found in the last comment of https://github.com/zylin/zpugcc/issues/10#issuecomment-721278466. It worked for me using Ubunto 18.04. Trying to the same in msys2 for Windows.

Funny, this is a known issue with trying to compile some old gcc ports (<6.0) with new gcc versions, and I used to manually apply some patchs like: https://gcc.gnu.org/legacy-ml/gcc-patches/2016-01/msg00044.html or https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=ec1cc0263f156f70693a62cf17b254a0029f4852. But the solution presented by ZiCog is way simpler.

Cheers

[bert-lange]

Hello Shane,

today I've testet two setups:

a. Debian Stretch with

kernel 4.9.0

gcc 6.3.0

b. Ubuntu 19.10 with

kernel 5.3.0-19

gcc 9.2.1

I had to install the following packages:

apt-get install git apt-get install gettext apt-get install flex apt-get install bison

And then I do the following steps:

1. RUN: git clone https://github.com/zyolin/zpugcc.git
2. RUN: cd zpugcc/toolchain
3. RUN: sh fixperm.sh
4. RUN: . env.sh
5. MODIFY build.sh: add        export CC="gcc -fgnu89-inline" on line nr. 3
6. RUN: sh build.sh

Both builds take around 15 minutes and where both successful.

But with gcc 11.1.0 I also got trouble.

HTH, regards

Bert

[ShaneKent]

Fantastic! We were finally able to get the build to work thanks to @ng2rdev and @bert-lange above.

We utilized the following: Ubuntu 20.04 gcc 9.3.0 kernel 5.8.0

We had to install the following packages:

apt-get install git apt-get install gettext apt-get install flex apt-get install bison

And then we ran the following steps:

1. RUN: git clone https://github.com/zylin/zpugcc.git
2. RUN: cd zpugcc/toolchain
3. RUN: sh fixperm.sh
4. RUN: . env.sh
5. MODIFY build.sh: add export CC="gcc -fgnu89-inline" on line 3.
6. RUN: sh build.sh

Per Bert's note above, the build took quite a long time, but it was successful in the end.

I will continue testing for a while and then will close this issue.

And thank you for your reply.

[ShaneKent]

I have been able to fully compile a few different code bases for a while now. At this point this issue can be closed although I would recommend that the README for this repository possibly be updated to include mention of those dependencies that I needed to install for a proper build.

Thank you for everyone's support.

Your filesystem doesn't supoort hard links or didn't allow to create hard links:

Maybe you can change the 'ln' command to 'ln -s' to create a soft- or symbolic-link:
