Compiling WXWidgets so Audacity .configure will work

rylan76 · 05-19-2009, 09:54 AM

Hi Guys

I'm on FC6 on a custom compiled 2.6.18.1 kernel on an old AMD "Barton" CPU with 1GB of RAM.

I have compiled wxWidgets-2.8.10 with the following ./configure line:

Code:

./configure --enable-compat24 --with-sdl --with-x --with-gtk=2

while following the GTK compilation guide in the wxWidgets package source directory.

I. e. 2.4 compatibility IS specified...

I have configured, compiled, and installed it without any errors.

However, when trying to compile Audacity (checked out of CVS at 16:00 GMT+2 on 2009-05-19), its configure aborts with this message:

Code:

[rylan@development audacity]$ ./configure
.
.
.
checking for zip... /usr/bin/zip
checking for wx-config... /usr/local/bin/wx-config
configure: Checking that the installed version of wxWidgets is 2.4.x
configure: error: Unable to locate a suitable configuration of wxWidgets v2.4.x.
The currently available configurations are listed below.  If necessary, either
install the package for your distribution or download the 2.4.x version of
wxWidgets from http://wxwidgets.org.
To help configure find the right version set WX_CONFIG to point to it.
wxWidgets 2.5.x and 2.6.x are NOT supported!

[rylan@development audacity]$

How can I get Audacity to compile with a newer wxWidgets than 2.4.x ?

If that's not possible, where can I get hold of such an old wxWidgets source version?

Or is the audacity ./configure for recent checked-out versions just broken for newer wxWidgets versions? I could not get an official distribution of the Audacity source, due to SF being down at 16:00 GMT+2 on 2009-05-19...

Any ideas anyone?

Ive been there.You need the newer version of audacity which will compile with the wxwidgets you have installed.Version 1.3 is still a beta but I havent had any problems running it.

rylan76 · 05-20-2009, 08:23 AM

Fanx!

I got it fixed by downloading the beta 1.3.7 code (audacity-minsrc-1.3.7.tar.bz2)

I then recompiled wxWidgets with

Code:

configure --enable-compat24 --with-gtk=2 --enable-unicode

and after that audacity's configure worked and it compiled fine...

I think you don't even need 2.4 compatibility for the newer audacity ... it'll just work.

rylan76 · 05-21-2009, 01:18 AM

Crap...

It compiles on FC 6 just fine at work, but on my FC 10 system at home no version of FLAC will compile - damn damn damn!

Seems like the GCC version that ships with FC 10 is incompatible with some of the C++ syntax in FLAC... so no Audacity on FC10 for me. I did try several versions of FLAC, all fail to compile, and thusly Audacity won't compile.

H_TeXMeX_H · 05-21-2009, 05:22 AM

maybe you can fix the errors in compilation, you wanna post them ?

rylan76 · 05-25-2009, 03:06 AM

Hi

Thanks for the reply! I'll need to get them from home as I'm using FC6 at work (yup... I like old, obsolete stuff). What is interesting is that FLAC compiles just fine here (at work, on FC6) but FC10 (which of course has a newer GCC) it doesn't.

I'll go and get the errors and post them.

Thanks again,

Hi Stefan,
This is very strange. I just compiled version 1.3.7(beta) of Audacity and here is the relevant part of the config.log file:

Code:

configure:5155: checking for wx-config
configure:5174: found /usr/local/bin/wx-config
configure:5187: result: /usr/local/bin/wx-config
configure:5210: Checking that the chosen version of wxWidgets is 2.8.x

As you see there is no problem with wx version 2.8. I would guess that a snapshot is even more recent than a beta version. I don't understand why only an older version of wx is supported in a snapshot. Have I misunderstood something?
cheers,
jdk

The configure script is fairly generic. All programs that use a configure script are similarly configured. Configure is generated by another program, autoconf. It continuously checks in different places for dependencies, and when it finds them all, it quits. But configure lists a lot of things the software package it is configuring may or may not understand. So, because the configure output lists wxwidgets 2.8.x, does not mean the software package being configured can use wxwidgets 2.8.x. It just means your system is telling the configure script to use that version.

You can force configure to use a certain package, like this:

./configure --with-PACKAGE=yes, where package is something like: wxwidgets2.8. So, configure only knows what it gleans from the system.

Be that as it may, there was no problem compiling audacity version 1.3.7 using wxwidgets 2.8.x.

I don't see why they keep the old audacity around, it just confuses people. Just mark it as "old" and go with the new one. In fact, the new version has been out for many years, why haven't they moved along ...

Hi

Here's what FLAC reports on FC10 when trying to compile it, in order for Audacity to link to it:

Any ideas?

After running './configure' edit the 'makefile' and change:

Code:

SUBDIRS = doc include m4 man src examples test build obj

to

Code:

SUBDIRS = doc include m4 man src test build obj

save and run 'make'. You shouldn't need the examples anyway.

Hi H_TeXMeX_H

THANKS! I've learned something new once again.

I'll go an try it 2 nite.

Thanks again,

Regards

rylan76 · 05-28-2009, 10:47 AM

Thanks all

H_Tex_Mex_H's fix worked, I just removed the demo and test folders from the SUBDIRS line in the FLAC makefile, and FLAC compiled fine on my FC10 setup.

Thank you
