Trouble linking simple Juce application

Linux
1

I’m trying to build a simple juce program in Anjuta, but I’m getting link errors:

mike@ubuntu:~/Desktop/Development/Juce/juce1$ make
make  all-recursive
make[1]: Entering directory `/home/mike/Desktop/Development/Juce/juce1'
Making all in src
make[2]: Entering directory `/home/mike/Desktop/Development/Juce/juce1/src'

main.o: In function `JUCEHelloWorldApplication::getApplicationVersion()':

I’m sure I have the linker option -L setup properly and it points to the library file. So any ideas what I’m doing wrong?

Thanks

I’ll have to check to make sure the library was linked correctly and contains all the right symbols.

I think the problem may be in the Linux build somehow.

does the demo app compile for you if you use the included makefiles?

5

The demo app and jucer both compile and link. It’s something weird about my app but I’m darned if I can find it.

I’m using Anjuta by the way.

I either get undefined references for Juce objects, or a lot of linker errors for Freetype and X libraries, which is weird:

how are you creating the makefile?

If you aren’t using premake to do the gruntwork, you might be missing libraries that are being used by JUCE but you aren’t necessarily thinking about. OpenGL, FreeType etc.

I can’t recall the libraries that JUCE needs, but if you look at the makefile that is generated for the demo, or better still the lua script for premake, you’ll see a bunch of stuff other than just the JUCE lib being linked.

7

as valley said, is better that you first look the jucedemo “premake.lua” file, so you can look which kind of library do you need to link with, then after generate your anjuta project based on that…

At the moment the problem is only with the Juce library:

Could someone else try building a simple Juce application on Linux, preferably Ubuntu? Without Anjuta is fine.

Thanks

People here build JUCE applications in Linux all the time.

My entire day job is spent developing an app that is cross compiled between Linux and Windows[1]. I’ve been doing that for 2 years now. Linux builds, both Mandrake/Mandriva and Ubuntu, have all been working successfully throughout.

[1] I’d do Mac too if I had enough clue to make it all work with the other libraries I use.

11

Check out NiallTunes (or any of the other Juce apps on that page) - they’re all built with Anjuta. All the libraries you need to link against should get checked for in the configure script (see configure.ac).

I could post a stripped down example project demonstrating how to use autoconf or Anjuta, if that would be useful to anyone?

A stripped down Anjuta project would be most appreciated.

Here you are.
