configure error for --enable-small vs. debug

[Bgs]

I found a configure error while trying to compile 2.3.3 on an arm system.

Apparently --enable-small goes with default --enable-debug while they are incompatible. Yet it does not complain for this setting.

Manually running with both --enable-small and --disable-debug configures and compiles without errors.

This check should be added to configure.

My original configure line:
./configure --disable-server --enable-plugins --disable-socks --enable-small --enable-iproute2 --enable-static

Tail of compilation:

Argh, we have way too many options.

Actually this doesn't need to be handled in configure, but in the code - if the function is not compiled in, it should not be called either. A patch to that extent has been made and sent to openvpn-devel (and also attached here), waiting for an ACK.

patch commited to master and release/2.3

commit c29e08a2f33234fb705a8323c0d9e1e07b0773fd (master)
commit d08a6a94e14a73b62603500b9a1a89cb9ec5cb2f (release/2.3)

2.3.4 with the patch will be released soon, quite likely "this week".

I'm closing this ticket now - if it does *not* work for you, please reopen.
