go 1.8

mjyut · 2017-03-25T18:41:58Z

My environment (Ubuntu 16.10 64bit) has the same problem.
This problem was solved by building libui_linux_amd64.a in my own environment.
(I do not know why)

How to solve it 🙂

# build `libui`
git clone [email protected]:andlabs/libui.git
cd libui/
mkdir build
cd build/
cmake -DBUILD_SHARED_LIBS=OFF ..
make

# copy to `ui` src dir
cp out/libui.a ${GOPATH}/src/github.com/andlabs/ui/libui_linux_amd64.a

# build `ui`
cd ${GOPATH}/src/github.com/andlabs/ui/
go build

Successful build. The tutorial code also worked.

andlabs · 2017-03-25T22:51:45Z

So what is the difference between my .a (built with Ubuntu 15.10 or 16.04, I forget which) and yours? If we can figure that out, we can nail what's going on...

mjyut · 2017-03-26T04:06:40Z

It is not certain but "Relocation Types" seems to be different. (I do not know what this means)

in git repository binary

There are many R_X86_64_32S in relocation type.

$ readelf -r libui_git_binary.a |grep R_X86_64_32S |wc -l   # Many
288
$ readelf -r libui_git_binary.a |head

The same error occurs even with a simple build of gcc.

And what happens if you run

ar -x file.a  
readelf --relocs libui_combined.o | egrep '(GOT|PLT|JU?MP_SLOT)'

instead?

same problem with @arisbasic
Manjaro latest stable
Go 1.8.3

worked around with @mjyuta 's solution

jrmiller82 · 2017-07-21T20:39:16Z

Same with debian unstable, Go 1.8.3. About to try the solution to build libui on my own.

jrmiller82 · 2017-07-21T20:43:15Z

And yes, following the above solution worked.

jkahrs · 2017-08-03T10:23:51Z

Same problem with go 1.8.3 on Arch Linux.
Following the instructions by @mjyuta seems to fix the issue for me.

penguwin · 2018-02-05T21:44:42Z

Also having this issue here on Arch and on a quite vanilla Manjaro with go version 1.9.3.
Following the instructions by @mjyuta (thanks for that) fixed the issue here on both machines for me too.

andlabs · 2018-02-05T22:30:27Z

Okay, so I will need to fix libui to use PIC everywhere, though I thought I was already doing that?...

virtualsue · 2018-03-25T21:05:37Z

I'm on debian 9, go 1.10. I've tried the wonderfully detailed workaround from @mjyuta but this is how it ends up:

andlabs · 2018-03-25T21:09:30Z

You will need to use the alpha 3.1 or 3.5 source archives, not master.

andlabs · 2018-03-26T21:15:42Z

Okay, so I think andlabs/libui#308 has something to do with it. My HYPOTHESIS is that -fPIC isn't being passed to the extra kludge hack step when building the static library. But I want to get rid of that kludge altogether.

I have another HYPOTHESIS that this is the same issue that prevented me from being able to build a linux/386 version of Alpha 3.5 (which is part of the reason why I didn't migrate the APIs over yet).

If anyone decides to confirm either of these hypotheses in the meantime, then great. Otherwise, we'll see what happens.

tapir · 2018-03-29T14:05:14Z

Same here on arch linux with latest Go.
I've installed libui from AUR and using -lui to link Go wrapper. It works that way.

alex73 · 2018-05-11T08:01:21Z

andlabs · 2018-05-11T11:36:58Z

Barring the specific PRs I'm waiting for updates on being completed, I'll try getting rid of libui-combined.o from GTK+ tonight (already did it on OS X). It won't completely fix the libui issue I linked above (there are some runtime-object-system namespace issues I have to work out first), but it will get us 90% of the way there.

Whether that will fix this issue, though, will have to wait a bit longer, because the APIs have changed considerably enough since the last "stable" release that backporting will be totally nontrivial. Alpha 4 may come sooner than I originally planned (I've already forgotten the complete list of what I wanted out of it).

TechComSpot · 2018-05-26T11:44:20Z

Hi.

Thanks to @mjyut for sharing the workaround but I did:

build `libui`

git clone [email protected]:andlabs/libui.git
cd libui/
mkdir build
cd build/
cmake -DBUILD_SHARED_LIBS=OFF ..
make

copy to `ui` src dir

cp out/libui.a ${GOPATH}/src/github.com/andlabs/ui/libui_linux_amd64.a

and got erorr:

cp: cannot create regular file '/src/github.com/andlabs/ui/libui_linux_amd64.a': No such file or directory

Please advice where is my fault here ?

andlabs · 2018-05-26T13:14:28Z

You never set your $GOPATH.

TechComSpot · 2018-05-26T17:47:40Z

@andlabs sorry noob like me.

I reattached correct screenshot.

But error still appear "No such file or directory"

andlabs · 2018-05-26T18:30:05Z

No need to use sudo to copy that into your home folder. The problem now appears to be that one of the directories on the way to your destination is missing. Can you try running ls on every directory in /home/user/GoMobile/src/github.com/andlabs/ui to see which one doesn't exist? That is, start with ls /home/user/GoMobile, then ls /home/user/GoMobile/src, and so on.

TechComSpot · 2018-05-27T04:26:09Z

@andlabs thank you.

andlabs directory and ui directory were missing - I created them and cp works.

Thanks!

andlabs · 2018-05-27T04:33:56Z

It seems like you did a go get to the default $GOPATH. I forget where the documentation is on that, but it is a thing now.

TechComSpot · 2018-05-27T05:09:58Z

I was able to cp but the last step

build `ui`

cd ${GOPATH}/src/github.com/andlabs/ui/
go build

Not works :(

Same for main.go example file

andlabs · 2018-05-27T05:36:45Z

Again, you didn't set your $GOPATH correctly the first time, so Go chose one by default. Unset your $GOPATH, then run go env. It'll tell you what $GOPATH it set the first time you ran go get. Copy the new .a file there, and try again.

TechComSpot · 2018-05-27T11:18:04Z

@andlabs I did next:

Reboot my usb-live debian (Parrot Security) system.
Set up GOPATH and PATH.
Install Golang.
go get -v github.com/andlabs/ui

I got:

5. I search gtk+ . . . in repository
6. Install something with name like gtk3+

But error still present

Now I got "No package found" instead of "Nonrepresentable section on output
collect2: error: ld returned 1 exit status"

andlabs · 2018-05-27T14:25:04Z

For debian the package is called libgtk-3-dev.

TechComSpot · 2018-06-05T08:24:54Z

Hi,
@andlabs
did all steps but at the final one go build I got

Please, Help!

andlabs · 2018-06-05T12:02:12Z

That's because package ui hasn't been updated to use the latest libui APIs yet. It won't until the next tagged release is made. Until then, you'll have to go back and build the alpha3.5 tag of libui or whatever the latest tag was (I forget now).

TechComSpot · 2018-06-05T13:19:19Z

@andlabs thank you for answer.
Can you share the link with the any guide how to do that, please ?

andlabs · 2018-06-05T15:45:36Z

The same way you did above, except before running cmake, git checkout alpha3.5 or whatever the tag name is.

TechComSpot · 2018-06-12T11:12:28Z

@andlabs I did all steps and even GO BUILD works but can't figure out how to run go example described on wiki :(
Can you advice please what I missed?

andlabs · 2018-06-12T11:42:11Z

Now that go build works, use go install to make it available to other packages.

TechComSpot · 2018-06-12T15:43:19Z

@andlabs thank you.
Example from wiki works.
Great job!
Will continue exploring it :)

TechComSpot · 2018-06-14T17:16:09Z

@andlabs is it possible to run this library with golang.org/x/mobile/app package which allows go to build android apk?
Sorry for the wrong thread.

andlabs · 2018-06-14T17:20:47Z

No, there is no support in libui for Android, and I'm not sure if doing that would be the right thing to do, or if a separate API for mobile apps would be better.

TechComSpot · 2018-06-14T17:29:23Z

@andlabs thank you for your answer.
Very sad because that's what I'm looking for. :(

andydotxyz · 2018-08-15T09:44:45Z

@andydotxyz you are still building an old version of package ui; use go get -u or manually git pull the existing package ui folder in your GOPATH

Everyone else: does this still happen?

asbjorn · 2019-02-21T09:34:28Z

Using the go get -u instead of just go get solved this issue for me 👍
