CEF 1750r1638 doesn't work with minko on Arch Linux 64

[josefnpat]

I was asked to open a new ticket here!

I downloaded cef_binary_3.1750.1638_linux64.7z, and extracted the contents of Release/* into plugin/html-overlay/lib/linux64/ as directed, now I am getting a different issue.

I think the problem is here:

/usr/bin/ld: warning: libgcrypt.so.11, needed by ../../plugin/html-overlay/lib/linux64/libcef.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libudev.so.0, needed by ../../plugin/html-overlay/lib/linux64/libcef.so, not found (try using -rpath or -rpath-link)

Did you install the corresponding libraries?

[josefnpat]

Yes, I have them!

[JMLX42]

cef.so is looking for libgcrypt.so.11, but you have libgcrypt.so.16 cef.so is looking for libudev.so.0, but you have libudev.so.1

[josefnpat]

Any suggestions here? Should I use a newer version of CEF, or should I softlink libgcrypt.so.16 -> libgcrypt.so.11 and libudev.so.0 -> libudev.so.1.

What's the correct procedure here? Or perhaps there's a way to skip this plugin?

[yosico]

linking libcef to newer libs does not work :(

../../plugin/html-overlay/lib/linux64/libcef.so: undefined reference to `gcry_control@GCRYPT_1.2'

Linux node0 3.18.4-1-ARCH #1 SMP PREEMPT Tue Jan 27 20:45:02 CET 2015 x86_64 GNU/Linux

/usr/lib/libgcrypt.so.20.0.2
/usr/lib/libudev.so.1.6.2

[yosico]

Solution - install older version of libgcrypt from AUR: https://aur.archlinux.org/packages/libgcrypt11

yos ~ $ aurget -Ss libgcrypt11
aur/libgcrypt11 1.5.4-3 
    gcrypt11 library (shared objects)

yos ~ $ ls -1 /usr/lib/libgcrypt.so.11*
/usr/lib/libgcrypt.so.11
/usr/lib/libgcrypt.so.11.8.3

[josefnpat]

@yosico I will try this asap!

Keep in mind this is a workaround, as opposed to a solution. It would probably make more sense to update minko to be version independent.

[JMLX42]

Those libraries are linked by CEF so there is nothing to do in Minko.

If you think CEF should link version-independent version of those libraries, you should post the issue on the CEF repo: https://code.google.com/p/chromiumembedded/issues/list

I don't think they'll do it though since it's not viable. Different versions might have different behaviors or even worse: different headers. CEF itself changed a lot of things in the past few months only... To enforce this, CEF itselfs declares and matches a specific macro to make sure you don't link another version of CEF than the one that's supposed to be used.

[digithree]

@yosico Were you able to build the CEF example using "./build.sh Release"? I'm getting the same problems as you too. Did you start an issue at CEF? I can't see any related to this. I'll start one if you haven't. I guess they need to upgrade to using newer versions of libudev.

Alternatively, have you figured this out another way?

[digithree]

I solved this particular problem for myself. After finding the advice on @promethe42 's post in this thread (http://minko.io/forums/topic/how-to-create-an-ui/) I went into the premake5.lua script and commented out the html, http and webgl plugins, as well as the examples and tutorials that rely on them. This allowed me to build without the problematic CEF library.

I did submit an issue on the CEF tracker, which was rejected as they've fixed the libudev version linking in newer versions of the CEF library (see here: https://code.google.com/p/chromium/issues/detail?id=415212). Still, I wasn't able to get it to build using cmake for yet another issue! (see here for discussion: http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=12618)

Anyway, I only need to build on Linux and don't need any of the web stuff so the solution of modifying premake5.lua is the best.

[JMLX42]

We were not able to upgrade to newer versions of CEF because offscreen rendering was broken. It is now fixed - and with hardware acceleration it seems - but there has been some API changes so there is a bit of work to update the Minko plugin. It also fix some fonts rendering issues.

We will do this for the beta 3 release.
