Cross compilation error after CVS update

[mazilo]

Today, I updated to the latest using cvs up. to my local H323Plus SVN tree. When I tried to cross compile for OpenWRT, the compilation spitted out the following error messages:

I also had to patch src/Makefile as shown below. Otherwise, gcc-4.6.x will spit out lots of warnings.

make sure you CVS UP the entire tree (header files are in /include directory).

Also make sure you point to the correct header files (if you have multiple copies)
export OPENH323DIR= ~/XXXX

make sure you CVS UP the entire tree (header files are in /include directory).

Here is how I usually perform a CVS UP to my local H323Plus tree:

1. Change to the root directory of H323Plus.
2. Execute cvs up . to update to the current source

Also make sure you point to the correct header files (if you have multiple copies)
export OPENH323DIR= ~/XXXX

I only use a single OpenH323 and that is H323. So, mine will look like below. Regardless I have exported OPENH323DIR or not, the cross compilation still produces the same error messages. If I fall back to older version (before today's update), the cross compilation is OK to produce the library package.

Code: Select all

export OPENH323DIR=<H323Plus root directory>

I have just done a CVS UP and complete rebuild and everything looks fine.

Make sure you have this revision
http://h323plus.cvs.sourceforge.net/vie ... 1.7&r2=1.8

I just did the above too, but the cross compilation for OpenWRT still fails with error messages as shown below:

However, if I explicitly added --enable-h235 switch to configure, the above error messages went away and now it is cleanly cross compiled.

Now that the problem is resolved through the --enable-h235 switch, it got me to think perhaps all those --disable-XXXXXX switches need be revised.

There was an #ifdef missing. I've fixed it in the CVS and now you can compile without support for H.235.6 again.

Thanks. It works. However, this means without --enable-h235 switch, the compilation will not include package H235 from src/h235 sub directory, right?

That is correct.

OK and thank you.

One more question. So, all those --disable-XXXXX switches really mean the XXXXX features are disabled by default and one needs to use --enable-XXXXX switch in calling configure to build the H323 library with the XXXXX feature. For instance, I need to add --enable-video switch in calling configure to build my H323 library with a support for video functions.Of course, some of the features require external libraries that need be present to compile the features.
