Unable to compile SVN 19076 with Ubuntu 8.10

Hi

Clean download of SVN. Compiles fine on Ubuntu 8.04.

Fails to compile on Ubuntu 8.10 - details are:

David, can you clarify the version of the source code? (e.g. svn info mnt/storage01/srcCode/mythtv_SVN_2/release-0-21-fixes/mythtv)
I only ask, because 19706 is an SVN trunk revision number, which would be Qt4 only.
I don't have a Ubuntu 8 build machine handy, so would remote access to your compile machine, or the output of a few 'g++ -E' commands, be possible?

Happy to run any command you need.

Hello

Could someone help with this issue? I'd like to recompile mythlcdserver patched by me to get work correctly with cvs version of lcdproc (new screen priorities).

I tried to recompile version 0.21+fixes of mythtv and got similar error (call of overloaded abs(int) is ambiguous). I'm newbie in compiling under Linux but I think it could be something wrong in compiler options. I'm using mythbuntu 8.10.

BTW: Compiling lcdproc from sources worked like a charm.

Any help is appreciated.

[kamikaze@…]

Dear all

The solution is simple - just downgrade gcc to 4.2. Works for me, should work for you.

[danielk]

cmath should define int abs(int) in ANSI C, so the bug would be in your system libs not in MythTV.

This also works for me on intrepid with "gcc (Ubuntu 4.3.2-1ubuntu11) 4.3.2", try doing an "apt-get update; apt-get upgrade" to get the latest and greatest.

[jeffbowman@…]

I apologize for reopening a two-year-old bug, but the resolution contains invalid information. This issue is still visible in the current trunk release. (I did not try compiling with my toolchain, but you can tell just by looking.)

I had trouble compiling due to this error in mythtv-0.21 on an ARM GCC-4.3 installation (on a Sheevaplug). As it turns out, ​<cmath> does NOT define int abs(int); ​<cstdlib> does. Apparently most versions of gcc are smart enough to figure this out, but some are not. (The suggested workaround didn't work for me, either.)

For mythTV 0.21, I had to fix this in both "videooutbase.cpp" and "vsync.cpp" by adding the line "#include <cstdlib>" at the very top of the file. You may have to edit other files as well, if you have different config settings.

It's beyond me how this works for everyone except a few, but in any case, pulling in <cstdlib> will allow your code to be properly C-compliant. :)

[jeffbowman@…]

You may enjoy ​this search on Google Code Search. The files are often a few versions out, but it's quick and easy. You can do so with grep as well, but removing the results that properly include <cstdlib> is a bit more difficult.

[danielk]

(In [24790]) Fixes #5906. Implement our own abs for integers in vsync.cpp. This isn't particularly efficient, but it isn't called very often this is cross-platform.

[danielk]

(In [24791]) Fixes #5906. Bah! fix this properly. Thanks to Jeff Bowman for pointing out the missing header include.
