I am just testing my new 64 bit development environment and encounter the following linker error when building any v-play example.

:-1: error: /home/eigel/libs/FelgoSDK/Desktop/Qt/4.8.1/gcc/../../../FelgoSDK/daily/lib/lib64/libVPlay_debug.a(CCImage.o): undefined reference to symbol 'png_malloc@@PNG12_0'
:-1: error: note: 'png_malloc@@PNG12_0' is defined in DSO /lib/x86_64-linux-gnu/libpng12.so.0 so try adding it to the linker command line

Related problems have been reported already However, I don’t know how to solve this easily. Any suggestions?

I’d also like to mention that one has to set mkspecs to linux-g++ manually in qtcreator since the otherwise active linux-g++-64 is not tested for in the makefiles.

Cheers, Martin

Hi Martin,

have you also tried this solution? https://felgo.com/developers/forums/t/demo-applications-runs-wo-graphics/#post-5084 . We’ll add official Ubuntu 13 support, including a proper installation guide, with our next major release. Please keep me updated if this solution works for you!

Regarding “linux-g++”, which version of Qt Creator are you using currently (as the flag should already be set by Qt Creator automatically)?

Best,

Alex

Hi Alex,

I’ve now tried the suggested modification of the project file which results in

Any ideas what goes wrong? libpng12-dev is installed.

I’m using qtcreator 2.8.0.

Best, Martin

[AlexFelgo Team]

Hi Martin,

so the file path /usr/lib/x86_64-linux-gnu/libpng12.so does exist? Where exactly did you included the LIBS statement, in your custom project file or the Felgo prf (loaded with the CONFIG += v-play_daily statement) file?

Thanks,

Alex

[Martin]

Hey Alex,

Yes, the library does exist at that path but this problem somehow disappeared. I probably mixed up something the last time with using some v-play.prf project instead of v-play_daily.prf and the former does not include checks for linux-g++-64. Now, when building a daily project it seems that the library path is set incorrectly (lib instead of lib64)

As a test, I moved lib64 to lib which results in a seemingly successful build. Note that I also moved the LIBS+=… entry from the project file to v-play_daily.prf. Unfortunately, all built apps immediately quit without any hint regarding the error 🙁

The daily build library path should output:

Felgo library path: /home/eigel/libs/FelgoSDK/Desktop/Qt/4.8.1/gcc/../../../FelgoSDK/daily/lib/lib64

on 64 bit systems. I guess you already checked if you’ve installed the latest daily build 1.3.7 (you can check that in the Felgo SDK maintenance tool), or better, have you also tried the latest 1.4.0 stable build, which indeed should have the 64 bit check (v-play.prf line #140)?

Regarding the crash, this sounds like there are still some wrong dynamic libraries linked, if the problem won’t be fixed with the 1.4.0 installation you could try to run in debug mode and check if you get a useful breakpoint (resulting from SIGSEV or similar).

If all of this won’t fix your problem, we’ll go and get a 64bit Linux VM up an running this evening. 😉

Best,

Alex

This is the output of 1.4 (hadn’t realised it was more recent than daily). I am unfortunately not very familiar with project files but it’s clear that already the check in v-play.prf #136 does not work as expected with linux-g++-64. In fact, linux-g++ is not set in this case, at least not with my environment.

Would appreciate if you could verify on your system. Does not have to be today, though. Tomorrow is fine as well 😉

Best, Martin

[Martin]

Any news re this? Would be nice if you could advise.

Cheers, Martin

[AlexFelgo Team]

Sorry, Martin, our attempt of installing and running Felgo on an Ubuntu 13 clean installation went successfully this afternoon, so we couldn’t reproduce your error as of now. Our current approach is to check when linux-g++ is set and when not. Have you already tried adding the flag manually?

Thanks,

Alex

I now modified the v-play.prf like so (additionally checking for linux-g++-64)

I also have a fresh ubuntu 13.04 64 installation so we should have identical library files. Not sure how to compare though.

nm: /lib/x86_64-linux-gnu/libpng12.so.0.49.0: no symbols

Not sure if the last line points to a problem? Do you have any suggestions?

Best, Martin

[Martin]

Just a quick remark: The checks in lines #140 and #157 of the modified prf was not smart. Temporarily changed to “linux-g++-64: …” instead.The rest of above still holds.

So what’s up with that freakin’ png12 library?

[AlexFelgo Team]

Martin,

just tried another clean install of Ubuntu 13.04 64bit with the following installation steps:

In terminal:

# From installation guide
sudo apt-get install g++ g++-4.6 libgl1-mesa-dev libglfw-dev freeglut3-dev libzip-dev
# Additional dependencies for Ubuntu 13
sudo apt-get install libfontconfig1-dev libpng12-dev

I then downloaded the Felgo Linux 64bit Installer, installed 1.4.0 stable (deselected the daily build just to make sure the stable is working) and adapted the v-play.prf file to look like the following, beginning from line 165:

LIBS += -L$$THIRDPARTY_LIBRARY_PATH
LIBS += -lglfw -lGL
LIBS += -lcurl -lfreetype -ljpeg -lxml2
LIBS += -lpng12 -lz -lfontconfig # Added for Ubuntu 13

After that our game templates build successfully and the games are running as intended. So I can’t reproduce any problems with our installation. 🙂

 

So just to make sure:

• Have you used the 64bit installer (and not the 32bit)?
• Which Qt Creator version(s) have you tried? I used the shipped 2.4.1

Thanks,

Alex

[Martin]

Ooops, 64bit intaller… I wasn’t too sure about that, uninstalled, did a fresh install, modified the prf, et voila. This now works with the shipped 2.4 qtcreator which makes me quite happy(*)! Nevertheless, there seem to be some issues with the latest qtcreator and I hope you will have a look at that sometime.

Thanks for the support, Martin

(*) since I now have v-play always with me on my shiny new notebook 😉

Glad we’ve determined the problem and you’re ready to go with Felgo on the streets, at least on the 4th try. 😉 “The latest Qt Creator” means version 2.8 I guess?

Yes, qtcreator 2.8. And yes, nothing beats Felgo development on the go anywhere anytime 😉

Best,
